How to raise electrolyte density in a car battery at home

In car batteries that are in active operation over time there is a drop in density. This can occur in a number of reasons. Services offer services to adjust the density of the AKB. Also, the problem can be solved on your own. But first of all, it is worth familiar with how to raise density in the battery at home.

For what reasons are the drop in density

Before immediately proceeding with the correction, the problem should be understood due to its occurrence. For battery, the phenomenon of the density drop is a natural phenomenon. When discharge, it decreases, when charging rises.

Low indicators in the battery say the following:

  1. The battery is simply discharged.
  2. The battery suffered a recharge, because of which the solution was simpsed.
  3. Distilled water simply taped without measuring the indicators.

Pulling distilled water

In the first case, the fall is a natural phenomenon. In the second, when the battery suffered a recharge occurred partial bumping, which greatly affected the parameters of the fluid. In the third, the electrolyte density fell in the battery due to the large water content.

Important! The electrolyte density directly affects the quality of the battery. And most importantly, how she will keep charge.

It is recommended to constantly measure the electrolyte density indicator at the first signs. They can be attributed to the fast discharge of AKB. Otherwise, with long work with incorrect indicators, the plates inside the battery will be destroyed. You can fix this only completely replacing the battery.

Ways to increase density

Increase the density of electrolyte in the battery can be raised in several ways. They differ in their complexity of performance and durability.

Corrective electrolyte

Increased electrolyte density in the battery occurs in several stages. In this action, it is important to comply with the sequence, only in this case you can get reliable results.

The following tools and products will also be required:

  • hydrometer;
  • Glass containers;
  • pear to extract excess fluid;
  • gloves for protection;
  • Plastic protective glasses;
  • corrective electrolyte;
  • distilled water.

Hydrometer

Important! Before you begin work, you must make sure that the battery was several hours in the room with a temperature of 20-25 degrees.

Check density range

To reanimate the battery and raise the electrolyte density in the battery, the following steps are required:

  1. Charge a battery in which the electrolyte density presumably fell. It is important that the battery charges about 8-12 hours. It is necessary that it becomes completely charged, since this moment strongly affects the indicators.
  2. After charging, it is required to measure the parameter with a steamer in each bank of the battery. Indicators must be within 1.25-1.27 g / cm in Cuba. Deviation in the indicators between banks is allowed to 0.01.
  3. If the result was below the norm, it is required to pump part of the electrolyte from cans with unacceptable parameters.
  4. A corrective electrolyte is poured into the jar, in the amount of two less than the cleansing. Next poured distilled water to close the plates.
  5. As soon as the partial replacement of the electrolyte was performed, it is necessary to put the battery on recharging. It is enough 30-60 minutes. After you need to leave the battery for 2 hours so that the liquid is mixed.
  6. After the time expired, repeated measurement. If it is also repeated and below normal action.

Important! If it is planned to independently make a correction electrolyte it is worth pouring an acid into water, and not vice versa. Otherwise, the reaction will occur during which water will boil, and the acid is splashing.

Charging Alignment

For this method, you will need a charger for battery with the ability to adjust the output voltage. Easy charging that reduces current strength with full charge will not fit.

Adjusting the electrolyte density in the battery occurs according to the following scheme:

  1. The battery is fully charged.
  2. When the electrolyte begins to boil the strength of the current decreases to 1-2 A.
  3. While the electrolyte boils water from it evaporates and the density gradually rises.
  4. After a drop in the level, it is necessary to add electrolyte, and measure the density.

The fluid will be evaporated very slowly and may need more than 24 hours. This method is most safe. Due to natural evaporation, the replacement is made without pumping a chemical solution.

Connection to Akb

Full replacement

If at least in one bank, the indicators are lower than 1.18 g / m in the square, only the complete replacement of the electrolyte will help. This action is worth spending very carefully because when mistaken, the entire battery may fail.

The replacement is made as follows:

  1. From the cans in the battery, the maximum possible amount of fluid with a pear is reset.
  2. After that, it is necessary to gently flip the battery on the side and drill holes in each can. With them it is necessary to drain the remnants of the electrolyte.
  3. After that, all the tanks are gently washed with distillate. The holes are sealed with plastic, which is resistant to acid.
  4. A solution of electrolyte with the necessary density is poured into freshly leaned banks. Next, the battery is charging and checked for performance.

You can pour a ready-made correction solution, and after normalize the parameters simply topping distilled water.

Important! The battery is required to flip very carefully and slowly. The fact is that at the bottom there is a sediment from lead and with a sharp coup, it can get stuck between the plates thereby stroke. After that, as a rule, the battery becomes not capable.

How to downgrade

In some cases, the density does not fall, but on the contrary increases. This outcome also negatively affects the overall state of the battery. The decrease is as follows:

  1. Some electrolyte pumped out of the cans.
  2. After which distilled water is poured.
  3. The density is measured, and if it is above 1.27, it is necessary to add water.

It is advisable to introduce water gradually. This will help to avoid too strong lowering indicators.

Than dangerous high or low density

High density of electrolyte in the battery leads to rapid destruction of the plates. Over time, the plate will be eaten by acid, and the battery will fail.

The low electrolyte density in the battery does not allow the battery to keep the charge as much as the container drops. Also, the increased concentration of water increases the likelihood that in winter such a battery is simply zoomed due to crystallization at low temperatures.

Density and temperature

Also, the density is recommended to choose from the time of year and the region. The spread in parameters is not strong, but it will help to avoid many problems with battery service.

Tips and recommendations

In order for the density adjustment to be successful, and the battery was not damaged to follow some recommendations:

  • Measuring only at a temperature of 20-25 degrees;
  • All parameters are measured in a fully charged battery;
  • To adjust the use of a special solution with a density 1.4. You can not pour a more saturated acid solution, it will lead to heating electrolyte in the battery;
  • The fluid in each bank is adjusted, the main thing is that there are no more than 0.01 between the values ​​of individual containers;
  • The fluid should cover the plates for 1-2 cm.

Tip! If after all manipulations, the indicators fall in a short time and does not come back after charging the battery should be replaced.

Sometimes it is impossible to align the density of the electrolyte in the banks of the battery. This, as a rule, occurs due to the fact that the battery is not good and the battery cannot keep density.

Conclusion

Electrolyte density and its level have a strong effect on the performance and efficiency of the battery. Timely adjustment allows you to increase battery life. The main thing is to make all actions correctly in line with security standards.

Home> Accumulators> Car Batteries

Car owners are often faced with the problem of engine failure from launch. This happens due to the discharge of the battery and deterioration of the properties of the electrolyte. Before raising the density in the battery, you need to find out the reason for the deterioration of the quality of the acidic solution. After that, you can proceed to the restoration of the battery. Actions do not represent special difficulties.

Raising and checking the density of electrolyte in the battery at homeIn the process of operation, a decrease in the battery density is a common phenomenon, especially when the old electrolyte is untimely replacing.

Why the electrolyte density is reduced

Factors contribute to a decrease in density:

  1. Discharge. When the charge loss is reduced and the density of the filler. In the process of charging, this parameter gradually increases. If the battery loses most of the tank, we are talking about the fall of the concentration of the acid.
  2. Long exploitation or storage under conditions of low temperatures.
  3. Switching electrolyte when reloading. If the charger supplies too high voltage, the liquid electrolyte goes into a gaseous state and is output through the holes available on the body.
  4. Frequent addition of water. Drivers add liquid to maintain a stable electrolyte level. Not everyone uses a rayometer measuring density. Together with water, acid is thrown out, which leads to a decrease in concentration.

Raising and checking the density of electrolyte in the battery at homeAn example of sulfation of a car battery plates.

Hazards low and high acid concentration

Increased electrolyte concentration causes premature battery output. Acid destroys metal plates. Even steel is sensitive to the effects based on sulfuric acid.

Low concentration leads to such problems:

  1. Sulfate. The plates appear on the plates consisting of lead sulphate. The battery becomes unable to take a charge.
  2. Increasing the frost threshold. The liquid is crystallized already at -5 ° C. Ice shifts and damages metal parts. When deforming the plates and short circuit of the capacities, the battery is not possible. At a density of 1.28 g / cm³, the electrolyte will freeze only at -58 ° C.
  3. Problems when starting the engine. This feature is most pronounced in the winter.

Raising and checking the density of electrolyte in the battery at homeTo verify the density of the electrolyte, they use a densimeter (right).

Checking the density of electrolyte

It is possible to determine the density of the electrolyte at home. The procedure is recommended at room temperature.

Before starting work, prepare such tools:

  1. Protective gloves, suit and glasses. The composition of the battery filler includes an acid. In case of contact with the skin, the substance causes a chemical burn. Acid couples are dangerous, so they work only in a well-ventilated room.
  2. Densimeter. The device is used to measure density. It has a glass tube with a pear and a built-in range.

Alone, the density measurement is performed as follows:

Raising and checking the density of electrolyte in the battery at homeTo check the electrolyte density, the end of the densimeter is immersed in the battery capacity.

  1. The battery is removed from the landing socket. The protective casing is dismantled, screwed the plugs.
  2. Check the electrolyte level. In lead-calcium batteries, the solution should close the plates by 1.5 cm.
  3. The battery is fully charged. Checking density starts 5-6 hours after completing the charging. At a normal level of electrolyte, the Densimeter tube is immersed in banks, pumping out a small amount of liquid filler.
  4. Evaluate the instrument indicators. The areaometer should float freely in solution. The contact of the device with the walls of the container is not allowed. Indications are evaluated based on ambient temperature.
  5. Check the electrolyte density in the rest of the banks. Indications are recorded and compared with normal density.

This method of checking is suitable only for the collapsible battery when there is access to the electrolyte. The maintenanceable battery is equipped with an indicator, the color of which varies depending on the density of the filler.

How to adjust the density of the solution

Normal reading lies in the range of 1.25-1.29 g / cm³. If at a temperature of + 25 ° C is a lower value, it must be raised. A drop in concentration in one of the cans indicates a short circuit.

High values ​​are detected after charging with a powerful current accompanied by boiling electrolyte. It is possible to increase the density by adding acid, refueling the finished composition or use of the charger.

Cold Solution Density

In the cold season, the density of the filler of the charged battery should be 1.27 g / cm³. Additional adjustment in the regions with a harsh climate when changing the season is not carried out.

Preparing for the restoration of the battery

At the preparation stage, such actions are performed:

  1. Battery charge. It is impossible to start recovery at low charge. Adding an electrolyte contributes to a sharp increase in the concentration of acid. This leads to the destruction of metal plates, in which the battery is disposed of.
  2. Normalization of electrolyte temperature. The indicator lies within + 20 ... + 25 ° C. The electrolyte level in each bank should be normal.
  3. Inspection of the battery. The case should not have cracks and chips, especially near the conclusions. Damage contributes to swaying when trying to remove the accurate terminal.

Increased electrolyte density

If the density is more than 1.18, the finished composition with the normal concentration of sulfuric acid.

The procedure includes such steps:

  1. Battery discharge. The topping of the electrolyte is carried out only with full discharge. For this, the battery is connected to a powerful lamp or other energy consumer.
  2. Preparation of the correction component. The acid level in such a means should be at least 1.4 g / cm³.
  3. Adding a corrective composition. Preliminate part of the electrolyte existing. The density of the solution should rise to 1.25. The action is performed for each bank. The volume of the fluid being fused should be no more than 50% of the died. After adding the liquid, the battery shake, giving the filler to shuffle.
  4. Battery charge. The battery is left for half an hour, which allows concentrations to align in banks. The battery is connected to the charger for 30 minutes. The strength of the current must be minimal. 2 hours after stopping charging, the density and amount of filler measure the density. If the concentration does not rise, the above actions are repeated.

Is it possible to increase the minimum density

When the density drops to a mark below 1.18, the addition of acid turns out to be ineffective. To restore the battery, a solution is used containing greater than the electrolyte, the amount of active substance.

Raising and checking the density of electrolyte in the battery at homeBefore the fill of the new electrolyte old need to merge.

To replace the filler, perform such actions:

  1. Drain of content. The maximum amount of fluid roll out pear. Then the battery is placed in a large container and turn over side. In the bottom of each bank form a small hole. The battery is returned to the previous position and wait for the leakage of the liquid filler.
  2. Adding water. The liquid is poured through the covers of cans to remove the remains of the old filler. The previously made holes are closed with a polymeric material resistant to the effects of acids.
  3. Filling the battery with a new solution. If all actions are completed correctly, the battery becomes ready to use. The disadvantage of the method is to reduce the battery life. A few weeks the device will work, but then you will have to buy a new one.

How to increase with the charger

If the acid concentration fell over winter, it can be restored by supplying a weak current. Charging takes at least 3 days, it is considered effective if you cannot restore the battery with other methods. The contents of the full battery power when charging begins to boil. A sign of water evaporation is the formation of small bubbles on the surface.

Excess liquid evaporates, the acid concentration will increase. The overall level of the filler will become small, so you have to add a ready-made battery solution. After completion of the procedure use the range. If the instrument indicators are too low, charging and adding electrolyte repeat.

How to restore electrolyte density in the battery at home?

It often happens that with a long service, your car without visible reasons begins to start worse. And even with full maintenance there are no reasons for such behavior. Of course, the problem may hide anywhere. But sometimes the answer may be on the surface - insufficient electrolyte density in the battery.

It is also sometimes there is such a phenomenon as a battery self-discharge. In this article we would like to tell about how to check the electrolyte density in the battery at home. And what to do if the density when measurements turns out to be too low.

What is electrolyte?

Raising and checking the density of electrolyte in the battery at home

Let's start with the fact that the electrolyte is an aqueous solution of sulfuric acid, which, with the electrolysis reaction with lead sulfate (lead plates), creates the required voltage. Most often there are batteries for 12 volts, less often with 6 and 24-ex volt voltage.

Also, the electrolyte solution has a certain density at which it perfectly performs its functions.

In the case of a long discharge of the battery, substances that are in electrolyte under the action of the electric current are disintegrated, which reduces the density of the electrolyte.

And with insufficient density indicators, the electrolyte efficiency is reduced, as a result of which the car battery is worsen.

How to check the electrolyte density in the battery at home?

So, we want to measure the density of electrolyte at home. For this, we will need such a device as a carometer. It is a cylindrical body body from transparent glass.

At one end there is a hole for the fence of the fluid, on the other hand, a pear is built, with which the liquid is gained inward. Inside the cylinder is a float, with an applied scale for measuring.

Check density is best after 6-12 hours after complete battery charging. This will make it possible to most accurately determine the indicators. To measure the electrolyte density at home you need to perform the following steps:

  • First you need to attribute the battery to the warm room, the air temperature of which will be within 20-25 ° C and give it to warm up. The implementation of this condition will allow you to learn more accurate density of the areaometer.
  • Then it should be removed all the tubes from the battery and omit into one of the tanks with the electrolyte of the aometer spout.
  • Further, all you need to gain a sufficient amount of fluid so that the float in the cylinder can freely swim.

Raising and checking the density of electrolyte in the battery at home

At the very float there are special risks, noting which of them is fluid, you can easily determine the density indicators. But that the testimony is the most accurate, the area meter is just right, without tilting on the sides. All these actions must be done for each of the batteries can individually.

In a serviceable battery, the electrolyte density should be within 1.24-1.29 g / cm³. At the same time, the difference in the testimony between tanks should not exceed 0.01 g / cm³.

The fluid level in each bank should also be the same. Plates should not rise above the surface of the solution.

In a serviceable battery, lead plates must be immersed under a layer of electrolyte with a thickness of 12 to 15 mm thick.

If the density of your battery is below the norm, then you must add battery acid.

And if the indicators are 1.3 or more, you should add distilled water to reduce the concentration of the acid inside the battery.

Although for some cold regions of the country a high density indicator is the norm. Therefore, before starting any work, do not be lazy to find out the parameters of the Akb density according to your region.

Raising and checking the density of electrolyte in the battery at home

Remember that it is not necessary to use technical sulfuric acid to increase the density, it will only speed up the process of self-discharge and sulfate. A too high density rate will strongly reduce the battery life.

If the electrolyte density is normal in your battery, and the fluid level does not require an attractive, then you can close the plugs and put the battery into the machine. This is the completed verification process on this. And if there were any problems with density, then read further about how to enhance it.

Acid work safety

First of all, it is necessary to think about your safety, as you work with one of the most "strong" acids on the planet. Therefore, it is better to comply with safety techniques, prepare protective gloves in advance and soda.

Work only in rubber gloves and in no case use tissue, because acid does not react with rubber, and the cloth burns very well.

Have a solution of alkali at hand, and if you do not have it, the usual food soda is suitable. Soda or weak alkaline solution is necessary in order to neutralize the consequences of acid from entering the skin.

Raising and checking the density of electrolyte in the battery at home

If it was not possible to avoid acid from entering the skin on the skin, then immediately sprinkle this place with soda and scroll with massaging movements, and then rinse with water. In no case, do not wash off with water immediately, otherwise you risk a chemical burn add also thermal.

How to increase electrolyte density in the battery?

As a rule, the decrease in the density of the electrolyte indicates that the process of plate sulfation began. This is accompanied not only by changing the density, but also the battery capacity. Therefore, in such cases, the simple plot of electrolyte in the battery does not solve the problem. The density will certainly increase, but other battery characteristics will remain unchanged.

Many car enthusiasts in these cases advise the battery to change, otherwise there is a risk that the battery will refuse to the most inopportune moment. However, more experienced drivers know that the sulfate plates are quite reversible. This procedure is possible at home, using one way:

  1. Using a charger. In essence, charging across a specific algorithm or the use of special "smart" charging devices. This method is considered the most efficient. It not only increases the density in the battery, but also restores the performance of the AKB.
  2. Complete electrolyte change and careful cleaning of battery cans using soda solution. A less effective method, however, can inhale the second life in the battery.

In more detail how to restore the density of the electrolyte, raising it with its charger, you can learn by clicking on this link. Below will be described the second method of restoring the density of the Akb, the change of the entire solution.

To do this, you will have to pour the entire old electrolyte and replace it with a new one. If you have an insecured battery, you will have to buy a new source of electricity in the car. Although many motorists even in such ankb are managed to replace the solution, drill the hole in the right places.

Battery restoration by replacing the entire electrolyte solution

Before starting work, as mentioned above, you need to remove the battery from the car and put it in a warm place. After that, you should give it to warm up if you are going to change the electrolyte in the winter. The next step will be a complete charging of the battery with a small current.

Raising and checking the density of electrolyte in the battery at home

Next, remove the protection from it and unscrew all the plugs. Take the punch enema and give up the maximum amount of electrolytic solution from all compartments. Get rid of liquid residues, without the rowing banks of the battery can be two of the ways:

  • Slowly and smoothly turning the battery first on the side, and then turn it up at all. This is a less secure method, there is a high probability to shorten the jar in its execution.
  • Rotate the battery on the side, drill on the reverse side of the hole in each bank. Through these holes, it is safe to drain the residues of the solution. The holes later are simply sealed.

At the same time, be careful, you work with acid, do not forget about gloves. Pour the old solution into banks and cover the lid, this solution can be useful in the farm when cleaning some surfaces.

Next, proceed to the manufacture of soda mortar. We make it at the rate of 3 teaspoons of soda per 100 ml of water. The resulting solution is poured into the container and bring it to a boil. The next step is to fill the resulting hot mix in the banks of the battery for several hours. After that, the solution merges and washed several times with hot distilled water.

When you clean the battery from the remains of the old solution, you should add a new one. Fill a new electrolyte in each compartment to the desired level using a funnel.

If you do not have ready at hand, then do it yourself! To do this, mix the sulfuric acid and distilled water so that the solution is a density of 1.27-1.29 grams per centimeter cubic, depending on your region.

Raising and checking the density of electrolyte in the battery at home

Remember the main rule of the preparation of acid solutions. It is necessary to add acid into water, and not vice versa. Otherwise, due to the booming of the solution and its splashing, you risk obtaining chemically skin burns, as well as damage the mucous membrane.

The bay of the new electrolyte must be processed to charging the battery. The fact is that the new electrolyte immediately enters the reaction of electrolysis with lead sulfate plates inside the battery.

So, loses charge and therefore the battery needs to be charged. Charging is carried out at 0.2 amps until the density reaches the normal range of values.

Although other recovery battery charging techniques can be applied.

Desulfation Trilon-B

In addition to the soda solution, a special means is quite popular, which is intended for purifying lead plates from lead sulfates. In addition, this tool is well suited for flushing the car cooling system.

Raising and checking the density of electrolyte in the battery at home

After draining the electrolyte, the trilder solution is poured into each jar for about an hour. After that, the stormy reaction of its components begins, which is most accompanied by heating, and in some even foaming or splashing the liquid from cans. Therefore, it is best to carry out this procedure on the street.

The next step is to drain the solution, and then thorough flushing of all the cans of the battery with distilled water. And you need to do this at least in 3, or even in 4 approaches. After all the above-described manipulations in the battery, the electrolyte is poured by the desired density and is charged.

Raising and checking the density of electrolyte in the battery at home

Remember that the use of this agent on old batteries can lead to the destruction of the lead plates of the AKB.

This is all that we wanted to say on this issue, now you know how to check the density of electrolyte in the battery at home. And what to do if the density during measurements fell greatly. We hope that this material was useful for you. We wish you success in this difficult business!

We raise the electrolyte density in the battery

02/16/2018

Raise the battery density and what is needed for this

Many nuances in this matter. Sometimes it is easier to attribute the battery to the service center, where experts will be checked, if necessary, he will be charged, they will take 500-600 rubles from you and you will calmly ride further.

If a sorry for money, then the battery maintenance procedure should always be started with the preparation of the workplace.

We are needed broad, free from the rubble table, aareometer, charger, disposable cups, capacitance with a ready-made electrolyte 1.34-1.4, the necessary tool.

If our battery is serviced, then first it is necessary to check the density and level of electrolyte. If in some bank the level of electrolyte is low - it is necessary to add distilled water.

To gain access to the banks, you can use a conventional coin (ruble or double-channel). If the plugs are hidden and unscrewed off the coin - you can use a powerful wide screwdriver.

Raising and checking the density of electrolyte in the battery at home

First fill distilled water. A liter distillate bottle is about 100 rubles on the market. It is always necessary to observe the golden rule of the motorist - water is added, and not acid.

Next, put the battery for charging. Shooting the plugs should not. Modern chargers have a light indication of the charging process. You need to drive acb about 12 hours. As soon as the battery stops accepting the charge - we produce damility measurement.

We will need a carometer - a special device that measures the electrolyte density.

Normal density - 1.27. If it is necessary to raise the density of the electrolyte - in stores there is a finished electrolyte with a density of 1.34 - 1.4.

  • So, our batteries fully charged (judging by the indicators on the charger).
  • Now you can measure the density in each bank and it is desirable to write the testimony to write on the sheet of paper.
  • This operation must be done on a fully charged battery.
  • For example: after the measurement in all banks we see that in two banks density 1.16-1.17.

Our actions to raise density in banks

  • We use disposable cups (can be sturdy glass);
  • From the banks with a reduced density in the first cup with the help of a steamometer, we pump out the maximum possible volume of electrolyte. You can also use a medical pear - who has what is in the garage;
  • In no case cannot be merged the electrolyte turns over the battery. As a result of such actions from the bottom of the bank, raising the sediment;
  • In the second one-time cup pour the finished electrolyte with a density of 1.34 - 1.4. Now again, with the help of areometraial pear, we fill the electrolyte with an elevated density (to the level);
  • We carry out such an operation with a second bank.

It is necessary to wait about half an hour until the fresh electrolyte is impregnated with grilles in banks.

Next, using the hydrometer, we check the electrolyte density in two restored banks. Received 1.27. And it happens that one such procedure is not enough. Then the process repeat anew.

After that, again check the density of the electrolyte in all banks. If there are no large deviations in the testimony - again recharge the battery to such a condition when it ceases to take charge.

Well, in principle, and that's it! Details about what electrolyte in the article "What you need to know about the electrolyte for batteries"

P.S. In order not to damage yourself - with batteries and acid work very carefully, use individual means of protection (rubber gloves, apron, protective glasses).

In the workplace, do not use open fire, apply low-voltage lighting lamps.

How to raise electrolyte density in battery - Drive2

Raising and checking the density of electrolyte in the battery at home

I met this article and decided to share. Who has any considerations? Is the author right?

It often happens that already after a day after the car downtime, the engine becomes impossible - it does not twist the starter. It turns out that during this short period of time, the battery has time to discharge. In this case, the battery charging for quite a long time does not help.

Such symptoms say that the electrolyte density fell in the battery. This can happen due to evaporation of the solution, for example, because of its boiling when recharging (so that in the future, to exclude boiling when charging, read the article how to charge the auto battery correctly).

To maintain the level of fluid into the battery, it is usually topped with distilled water. After that, few people comes to check the density of the solution. And since the electrolyteok, the electrolyte is swollen with water, then this process leads to a gradual decrease in density.

As a result, after some time, its value becomes below critical.

And here is a natural question: how to increase the density of the battery? Following the instructions below, you can make sure that you can restore the battery yourself in the presence of the necessary tool and "direct hands". Whether to start working

Measure the battery density at air temperature 20-22s. Be maximally carefully when working with electrolyte (especially with acid), use safety glasses and rubber gloves. Chemistry lessons at school.

If you breed the electrolyte yourself, be sure to add acid into water, and not vice versa! Due to the difference in the density of both liquids, you can get serious burns. Do not turn the battery upside down. This can lead to a sprinkling of the active surface of the plates and short circuit. The complex under the drain of the old electrolyte and for breeding fresh should be prepared in advance.

Remember that the density of the charged battery increases. Check the plastic-used plastic holes to the chemical resistance with respect to the electrolyte.

  • The procedures described below and the reduced density values ​​of the electrolyte are acidic batteries, in an alkaline battery, these quantities are different.
  • Required tool
  • The device for measuring the density of the liquid meterometer (the device for measuring the density of liquids); a measuring glass; murrass (can be purchased in a pharmacy); electrolyte; distilled water; rechargeable acid; solution of food soda; soldering iron;
  • drill.

Electrolyte density in the battery: how to check and increase

The electrolyte density in the battery is the most important parameter for acid battery. From the density of the electrolyte directly depends on the service life and the overall performance of the battery, the battery capacity, the ability to accumulate and hold with the charge, and also work under load.

In this case, during operation, the density in the battery may vary, which indicates the need to check. Next, we will look at what the electrolyte density should be in the battery, how to check the battery density, as well as how to increase the density in the battery at such a need for the maintenance of the AKB.

What density should be in a car battery

So, before we consider which the density of the electrolyte should be and how to correct the density of the battery, it is important to understand that under such a density it is necessary to understand the proportion of acid in the solution, which is filled into the banks of the AKB.

First of all, the density check is an important step in the framework of the AKB service. So, in lead batteries, the density is measured in grams per cm3. The density indicator is proportional to the concentration of the solution, and also depends on temperature. The stronger the solution is heated, the less density will be.

In this case, the density of the electrolyte indicates that the ACB is located. As a rule, if the battery loses the ability to keep the charge, it is necessary to check the level and state of the electrolyte in banks. Such a check is carried out by the range, while the temperature should be about 25 degrees Celsius. If the temperature is different, it is necessary to make separate amendments (you can use the table).

We go further. During the operation of the AKB, it is important that the electrolyte density indicator corresponds to the norm, and with the climatic conditions. This means that the electrolyte density in winter and in the summer is different.

If the climate is moderate (there is no heavy heat and cold), the electrolyte density must be 1.25-1.27 g / cm3.

If in the frost region more -30, then the value is raised by 0.01 g / cm3 more, if there is a strong heat above +30, then the indicator is reduced by 0.01 g / cm3.

If the frost is strong (the temperature drops to -50 ° C) so that the electrolyte in the battery does not freeze, in this case, it is necessary to increase the electrolyte density in the battery in winter to 1.29 g / cm3.

For clarity, the electrolyte density table in the battery allows you to understand what the battery density should be in winter or in summer, in conditions of severe heat or cold, in moderate climate, etc.

It is important to take into account that the smaller the density is, the longer the overall service life of the car battery is. This means that without the need to raise the density is not recommended.

It should also be borne in mind that the battery installed on the machine is not charged by 100%, but by 85-90% of the rated tank. This means that the density of the electrolyte when measurements often turns out to be lower compared to the fully charged battery. At the above reasons, you need to select a value that is slightly higher (by 0.01) than is shown in the density table. This approach will mean that the battery will not freeze in the winter.

However, if we are talking about summer, too high density can lead to boiling electrolyte in the battery. It is important to comply with the balance, since the increase in the density reduces the battery life, while the decrease leads to a decrease in voltage, the battery turns the starter worse, it is discharged faster, etc.

We also add that if in the winter the temperature does not fall below -30 and does not rise above + 30 in the summer, then the standard value of the battery density should not be changed. The main thing is to ensure that this value is constantly preserved.

Electrolyte density in battery in winter and summer

So, the nominal electrolyte density in the battery in the winter is 1.27. If the temperatures are below -35, then the density increases to 1.28 g / cm3. In this case, further increasing density is also not recommended.

If the density is reduced, for example, up to 1.09, then the electrolyte will freeze already at -7 degrees Celsius. However, if in the winter it was found that the density dropped, instead of raising it immediately, you must first charge the battery from the charger.

In fact, in winter, often during short trips, the battery does not have time to recharge, badly accumulates charge, etc. As a result, the battery is reduced, and density falls. In this case, the density by means of an acid reeling is not recommended independently.

It is allowed to change except by using distilled water to correct the level (the rate of 1.5 cm above the plates in the passenger cars or 3 cm. In cargo cars). At the same time, if the battery is new or fully operational, the change in the electrolyte density with full discharge and complete charge should be at 0.15-0.16 g / cm3.

It is also important to take into account that it is impossible to use a discharged battery at a minus temperature, since the electrolyte freezes and lead plates are destroyed. In practice, if the battery is discharged in winter and more than a quarter in the summer, the battery must be recharged.

As for the density of the battery in summer, banks are usually dry and the density increases. Given that high density badly affects the plates, it is better to keep an indicator of 0.02 g / cm3 below the optimal value in the regions with a hot climate.

In fact, in the summer, water from the cans of the battery is actively evaporated, since the outer air temperature and heating under the hood (where the battery is often often) also lead to a strong increase in the temperature of the battery. As a result, the battery "boils".

At the same time, the decrease in density does not affect the quality of the current when the battery is heated. For example, even at 1.22 g / cm3, the battery will turn the starter well. It turns out if it is hot on the street, the electrolyte level decreases and the density increases. In turn, the high density "kills" the battery.

That this does not happen, you need to check the level of electrolyte and topping the water into the battery, lowering the density and maintaining the desired level of the solution in banks to prevent the reload and sweeping plates.

At the same time, it should be remembered that constant tallowing of water into the battery leads to the fact that the density falls.

At low density, it is impossible to further use the battery, as it is necessary to increase the electrolyte density in the battery.

How to check the density in the battery

Having understood with what affects the density in the battery and what it should be, we proceed to how the density in the battery is checked. Such an inspection must be performed every 20-25 thousand km. Mileage, as well as before the onset of summer and winter.

For measurement, you need a device called a carometer (densimeter). In fact, it is a glass tube with a storometer inside. At one end there is a tip of rubber, and on the other is a pear.

To check, it should alternately unscrew the covers of the cans of the battery serviced, then immerse the rubber tip into the solution, the pear pull the electrolyte. Next, the range with the scale will show, what is the density of the solution. The smaller the density, the lower the battery charge.

By the way, I will also add that the maintenance-free acb is not possible in this way, since there is no direct access to banks. At the same time, there is a special color indicator (density indicator) of a non-listed battery.

In fact, if the indicator is green, then it indicates that the battery is charged by 65 or 100%. If the density is low and the battery needs to be charged, then the indicator will be black. Moreover, if the color, for example, is red, then it indicates water boiling and the need for the topping. By the way, on the battery itself there should be a sticker indicating what the color of the indicator says in one way or another.

Now back to check. The electrolyte density check should be made on a fully charged battery. At the same time, the battery can be charged only when the level in banks is normal. In other words, the order is as follows:

  • First, the level of electrolyte is adjusted, then the battery is charged completely;
  • After charging and shutdown, the memory should also be given a battery "stand out" about 2-3 hours.
  • After checking the electrolyte density in the battery.

If you add water or charge the battery and immediately measure the density, the data will be not accurate. It is also important to measure the density at the optimal air temperature. If there are deviations, then you need to check the above table and make amendments.

When the electrolyte fence is made, the area meter must be alone and swim, while not touching the walls. Measures from each bank can be recorded. It is important that the electrolyte density is approximately the same in all banks.

If it is noted that the density has greatly decreased in one bank or several, but not in all, then it indicates defects. As a rule, we are talking about a short closure of the battery plates. If the density fell in all banks, this indicates that the battery in a deep discharge, the plates sat down or the old battery worked out its resource.

To accurately determine the cause, you need to check the battery voltage by a multimeter and with a load fork. In the case when the density is high, it also talks about problems. As a rule, the density increases when the electrolyte boils.

Anyway, you need adjustment using a corrective solution or distilled water, after which the battery is charged with a rated current (about 30 minutes), and then the battery is withstanding several hours at rest. It is necessary to align density in banks. Let's look at how to increase the electrolyte density in the battery, in more detail.

How to raise battery density

First of all, it is important to know how to correctly lift density in the battery. First of all, when working with the electrolyte, you need to be extremely careful, since there are sulfuric acid in the solution.

Acid can cause bodges of the skin, mucous and respiratory tract. It is necessary to work with the electrolyte in a well-ventilated room, put on gloves, mask, etc. You still need to take into account all the nuances and know how to raise density in the battery.

Note, the need to do this occurs when the electrolyte level in banks was adjusted several times with water or the density measurement indicate that the density is too low for winter.

Also increase the density you need after a long battery recharge. As a rule, it is necessary to lift density if the charge interval and discharge decreased significantly. For the concept of density of AKB, a concentrated electrolyte can be used (adjusting the electrolyte solution) or simply add acids.

In any case, you need to have an areaometer, a measuring glass, a capacity for electrolyte dilution, a corrective solution of electrolyte or an acid, distilled water.

  • In general terms, a little electrolyte is pumped out of the battery bank, then a correction electrolyte is added in the same amount to raise the density or distilled water to reduce;
  • Then the battery is then charged to charging from the memory, it is necessary to charge the rated current so that the liquid is mixed;
  • Next, the battery is turned off from the memory, the pause is withstanding about 2-3 hours, so that during this time the density in all banks is leveled, the bubbles of gases came out, the temperature was reduced;
  • Now you can again check the density of the electrolyte, if necessary, repeat the procedure, reducing or increasing the amount;
  • When measurements, the difference in density in all banks should not be greater than 0.01 g / cm3. If such a density is unable to achieve, then you need to make a so-called leveling charging again, and the current, which is 2-3 times less than the rated current of the charge.

To be more convenient, it is recommended to study in advance what volume in cm3 in each bank of a particular acb. The electrolyte itself has a composition in the following proportions: 40% of sulfuric acid by 60% distilled water. By the way, proportions and density can be calculated by the formula, however, it is easier to use this method in practice:

  • The liquid is pumped out of the jar and merges into a measuring glass, which allows you to determine the volume;
  • Then the half of the resulting quantity merges, and the other is filled with an electrolyte (the glass must be shown for mixing).

If the density values ​​are still low, then you can add another ¼ of the electrolyte from the volumetric volume. Such a topway can be produced repeatedly, reducing the number twice.

At the same time, if the density in the battery is too low (below 1.18), in this case there is not enough ordinary electrolyte topping. In such a situation, it is necessary to add acid (1.8 g / cm3).

The procedure itself is similar to the addition of electrolyte. The only one to add acid into solution is a step by step, as you can immediately pour a large number and exceed the necessary indicators. Note, during the preparation of the solution, it is mandatory to pour acid into water. Pour water into acid is prohibited!

Tips and recommendations

As practice shows, the battery life of the battery (average at a price) is 3-4 years, expensive analogues can serve 1-2 years more. In this case, such indicators are possible only if the rules of operation and maintenance are observed, as well as equipment properly.

First of all, it is important to prevent the battery recharge or, on the contrary, a deep discharge of the battery. As a rule, the owner itself can plant a lot.

Also, the discharge is the malfunctions of electrical equipment or errors when connected. Anyway, consumers "pull" charge even when the machine is not used, the battery sits down.

As for reloading, it can occur as a result of a breakdown of the relay regulator, etc.

In any case, if the battery is maintenance free and / or old (extended more than 3 or 4 years), then try to restore its performance by replacing the electrolyte. Often, in this case, the plates (partially or fully) have already appeared in the banks. The result is a battery will not work normally even with fresh electrolyte.

Often, if the electrolyte in the battery has become brown or brown, in frosts such a battery if it will work, it is bad.

If the electrolyte is painted, this indicates that the shiny of plates and particles have come into the solution. In fact, the surface area of ​​the plates has become less.

It turns out, even after servicing and charging, get the necessary characteristics of the AKB is not possible. In this case, the battery is better to change immediately.

That in the end

As can be seen, the density of the electrolyte, the level and its condition in the battery is the most important indicators. For this reason, not even normally working batteries need to be monitored by the electrolyte level in the banks of the battery, as well as check and adjust the density when the norm is deviating, taking into account the climatic conditions in the region, etc.

Finally, we note that only the correct maintenance, charging and compliance with the rules of operation allows you to maximize the efficiency of work and increase the battery life of the car.

What density should be an electrolyte in the battery in winter. All you need to know

Check density - This is one of the items of the battery maintenance process, since it will depend on it the degree of charge and the state of the battery.

What will directly affect whether you can start a car with a strong frost or not.

Therefore, if you have a battery serviced in your car, then you are simply obliged to know which electrolyte density should be and what to do when it differs from the desired value!

The battery density is measured at + 25 ° C. In case the temperature differs from the required, the amendments are made in the readings (± 0.01 g / cm3 ).

What should be the density in the automotive battery

  • The battery density should be established on the basis of the set of requirements and operating conditions:
  • With moderate climates must be at the level 1.25-1.27 g / cm3 ± 0.01 g / cm3;
  • - in the cold zone, with winters up to -30 degrees by 0.01 g / cm3 more;
  • - in the hot subtropical - on 0.01 g / cm3 less ;
  • - in the regions, Where is the winter of particularly severe (up to -50 ° С) have to raise the density from 1.27 to 1.29 g / cm3, In order, the battery is not frozen.

The smaller the electrolyte density in a fully charged battery, the longer will last.

Remember that, as a rule, the battery, being by car, charged no more than 80-90% Its rated containers, so the electrolyte density will be slightly lower than with full charge.

High electrolyte density leads to a decrease in the battery life. The low density of the electrolyte in the battery leads to a decrease in voltage difficult to start the engine.

Note that In winter, in the summer electrolyte density in the battery do not need to change , it is only required to measure and control so that it does not deviate from the nominal value . Only in very cold zones, where the thermometer column is often at the mark below -30 degrees (in the flesh to -50), the adjustment is allowed.

Reducing the density to 1.09 g / cm3, leads to the freezing of the battery at a temperature of -7 ° C.

In the event that the density and dropped to the critical value, this does not mean that it needs to be lifted using a corrective solution, first fully charge the battery using a charger.

Since half-hour trips from home to work and back do not allow the electrolyte warms up, and, therefore, it is well charged, because the battery takes the charge only after heating.

So the discharge of day after day increases, and the result is density.

The interval of changes in the electrolyte density from the full discharge to a complete charge of a serviceable battery should not exceed 0.15-0.16 g / cm3.

Measuring the density of the stage is important that the data in all cells were the same. Highly low density in some of the cells indicates the presence of defects in it. But if it is equally low in all cells, it indicates a deep discharge, sulfate, or just obsolescence.

If there is a need for density adjustment. You will need to select a certain amount of electrolyte with batteries and add adjusting (1.4 g / cm3) or distilled water with a subsequent 30 minute charging of the rated current and shutter speed for several hours to align the density in all compartments.

I met this article and decided to share. Who has any considerations? Is the author right?

It often happens that already after a day after the car downtime, the engine becomes impossible - it does not twist the starter. It turns out that during this short period of time, the battery has time to discharge. In this case, the battery charging for quite a long time does not help.

Such symptoms say that the electrolyte density fell in the battery. This can happen due to evaporation of the solution, for example, because of its boiling when recharging (so that in the future, to exclude boiling when charging, read the article how to charge the auto battery correctly).

To maintain the level of fluid into the battery, it is usually topped with distilled water. After that, few people comes to check the density of the solution. And since the electrolyteok, the electrolyte is swollen with water, then this process leads to a gradual decrease in density. As a result, after some time, its value becomes below critical. And here is a natural question: how to increase the density of the battery? Following the instructions below, you can make sure that you can restore the battery yourself in the presence of the necessary tool and "direct hands". Whether to start working

Measure the battery density at air temperature 20-22s. Be maximally carefully when working with electrolyte (especially with acid), use safety glasses and rubber gloves. Chemistry lessons at school. If you breed the electrolyte yourself, be sure to add acid into water, and not vice versa! Due to the difference in the density of both liquids, you can get serious burns. Do not turn the battery upside down. This can lead to a sprinkling of the active surface of the plates and short circuit. Package under the drainage of old electrolyte and for dilution of fresh should be prepared in advance. Please note that the density of the charged battery increases. Check the plastic sealing of the plastic screws to the chemical resistance to the electrolyte. The following procedures and the above electrolyte density values ​​are acidic batteries, in an alkaline battery, these quantities are different.

Required tool

Areometer Devices for measuring the density of the liquid meterometer (device for measuring the density of liquids); dimensional glass; murrass (can be purchased in pharmacy); electrolyte; distilled water; battery acid; food soda solution; soldering iron; drill.

Instructions for increasing electrolyte density

First of all, you need to measure the electrolyte parameters for each can separately. The answer to the question of which the battery density should be depends on the climatic conditions. Meal of the density of electrolyteav of the northern regions This value is somewhat higher, in the southern - below. The density of the solution must be in the range of 1.25-1.29. The scatter of values ​​for banks should not exceed 0.01. If the measured value was 1.18-1.20, then it will be more expedient to increase its increase by topping the electrolyte with a density of 1.27. At first we carry out this process for one bank. We pump out with the help of a tuber-pear as many old solutions as possible and measure its volume. Press the fresh electrolyte with a half of half from the diverted. After this, you need to actively shift or shake the battery, so that the fluids are mixed. If the value has not achieved the desired, we fill half from the remaining volume. The operation repeat, until we obtain the density value you need. Polize the residue with distilled water.

How to raise density in the battery, if it fell below 1.18

In this situation, one electrolyte can not do. Here you need rechargeable acid, the density of which is significantly higher. We produce the process according to the same scheme as in the case of the addition of electrolyte. If the first time to raise the density to the desired value did not work, it is necessary to repeat the procedure until the desired value is reached. To enlarge a very low electrolyte density in the battery

If, according to measurements, we obtain a completely low electrolyte density, it is necessary to make it a complete replacement. To this end, we first pump out the maximum volume of the solution with the help of the "pear", then tightly close the ventilation holes of the traffic jams on the battery banks. We put the battery on the side and the drill of 3-3.5mm we do the holes alternately in the bottom of each can, merge the electrolyte. After that, we thoroughly rinse the battery with distilled water. We seserve the drilled holes of the acid-resistant plastic (for example, from the tube from another battery).

Density recovery

Now you can pour fresh electrolyte. It is better to use the cooked independent solution with a density somewhat higher than the calculated for this climatic belt. However, it is worth understanding that due to the peculiarities of the chemical processes occurring in the battery, after a complete replacement of the electrolyte, its service life will not be as long as the new battery.

How to increase the battery density at home

How to increase the density of electrolyte in the battery. Alone, charger without it. Simple steps

Surely most motorists faced the situation when the car left for a while ceases to start. At the same time, the starter may not submit any signs of life at all. The main reason for this is most likely the battery is that in a few days it is completely discharged. Attempting to charge it in this case will not lead to a positive result. A similar problem is the result of a decrease in the density of electrolyte, which is covered in the banks of the battery ...

THE CONTENT OF THE ARTICLE

After all, this liquid is essentially a catalyst for the electrochemical process, without it the battery is a set. lead And plastic that will not work. As we know, consists of from distilled water (approximately 65%) and Sulfuric acid (35%), this liquid has a certain density that can be reduced and increased, depending on charge.

Why does the electrolyte density decrease?

Most often, in order to maintain in the required level, the amount of fluid inside the automotive battery The owners of the machine taking a distilled water there. At the same time, the density of the resulting solution is rarely checked. At the same time, when the amount of distilled water is large enough, when recharging, together with this liquid, will also pour electrolyte, which leads to a decrease in its density.

Sooner or later, this indicator will fall below the critical level, and the vehicle will not turn out.

In this case, it becomes necessary to increase this solution parameter in the battery, which will return its performance.

Preparing for the restoration of the battery

Before you increase the level of battery density on your own, it should be carefully prepared. First of all:

  • This main indicator of the automotive battery is measured at a temperature of about 22 degrees. You can do this with a special device - the areaometer. At the same time, it is possible to work only in gloves and protective glasses to avoid possible burns.

  • When cooking a new electrolyte acid is added to water. If you do vice versa, liquid Start boiled What can lead to acid burns.
  • To turn the battery when working with it is strictly prohibited, since its plate can be sprinkled, which will lead to the exit of the device.
  • You should prepare the containers in which the old liquid will merge and prepare a new one.
  • Accurate calculations of the required acid volume are required, since in the process of charging the density of the liquid in the battery will increase.

Increased electrolyte density

There are several cans in the battery, the electrolytic solution is in each of them. Check and if necessary, raise the density level is necessary in each bank.

The normal level of this indicator depends on several factors, first of all - on air temperature. Normal is considered to be the value of 1.25-1.29g / cm3. The difference of such indicators between banks should not exceed 0.1.

If the measurement of this indicator is below the norm, it is necessary to increase the electrolyte density in the battery.

With the help of a fringe from each bank, a solution is discouraged. At the same time, you need to type as many liquid as possible, measuring its volume to then add exactly the same amount of fresh electrolyte.

The bay of as much fresh solution, how much the old one was extracted, the battery is hosted well in order to stirring the new and old electrolyte.

After that, the measurement of this indicator is again: if it is still below the norm, all actions are repeated until the desired density value is reached. Upon completion, if necessary, distilled water is added to the automotive battery banks.

Density below the minimum value

There are such cases when the level of this indicator falls below the 1.18 mark. In this case, the above method will not help anything.

To restore the efficiency of the battery, instead of an electrolytic solution you need to use acid, the density of which is higher, which is in electrolyte. At the same time, all actions are carried out in the same way as in the previous case until the indicator comes to normal.

Is it possible to increase the minimum density?

If the level of the density of the solution is that spending the current in the car's battery fell much lower than 1.18 g / cm3, there is no point in lifting it. In this case, it is necessary to drain the whole solution, replacing it fresh.

First, the cans are pumped out with the help of a scratch as possible an electrolyte as possible. Next, the battery is placed in a large container, gently turns over to the side, a small hole is drilled in the bottom of each can. Inverting the device, all excess the remaining liquid merge from it.

Next, distilled water is poured through the covers of cans in order to wash them. After that, the velocked holes are sealed with plastic, resistant to the effects of electrolytic fluid.

Having done this, a fresh solution is poured into the battery, after which the device will be ready for use. The disadvantage of this method is that the end result is reduced the service life of the device, but for some time it will still work until buying a new one.

How to increase with the charger

It is also simple here, we need to charge the battery on a weak current, a long period of time. The essence is as follows, when achieving a complete charge, the electrolyte will start boiled, bubbles will go, it disintegrates and water evaporates. To increase density, we need excess water evaporated, and the acid remained. Of course, there will be a level in the battery - but instead of the departed level, add the desired density of the electrolyte. This process is long and vigorous (bumping - adding), but in about a couple of days you can catch up to a density in 1.27 - 1.29 g / cm3, which is already normal.

As you can see how to raise density, it is possible, and this process is done often with your own hands, but in different ways - choose your own you need.

Increase the density of electrolyte in the battery

The electrolyte is a battery fluid consisting in an ideal concentration of 35 percent of sulfuric acid and 65% distilled water. On our portal Vodi.su, we already led the table in which the optimal electrolyte density in the battery is indicated. If you bought a starter battery in the store, the sales assistant was obliged to measure the density of the electrolyte, as well as check the battery under load. That is how the factory marriage can be revealed.

The electrolyte density may vary in small limits. However, if you measure it with a carometer at an air temperature of 20-25 degrees and with a complete charging of the battery, it should be 1.27-1.28 g / cm. cube But for various reasons, the density may decrease.

Why is this happening:

  • The concentration of sulfuric acid does not comply with the established requirements due to the regular attachment of distilled water;
  • Battery discharge;
  • frequent recharging leading to the boiling of electrolyte, evaporation of water and a part of the acid;
  • Splashing electrolyte and his leakage due to mechanical damage to the battery case.

Note that when the electrolyte is boiling, water evaporates mainly. The boiling point of sulfuric acid exceeds 300 degrees. Even if the battery is fully charged, the electrolyte density in different banks may differ slightly due to different concentrations. For this reason, it is not recommended to top up the electrolyte, and only water in equal doses into each jar.

How to raise electrolyte density?

Rechargeable battery manufacturers recommend regular density measurements at least twice a year during seasonal car service. If there are no special complaints to work the battery, it is enough to recharge it when the density fall. We also wrote about charging on our portal vodi.su. If the level of fluid in the banks dropped, it is necessary to add some water to make it 15-20 millimeters to cover the plates. With this approach, the acid is mixed with water during the engine operation.

The electrolyte density depends on the two parameters:

  • ambient temperature;
  • Sulfuric acid concentration.

It would seem that if the density fell, you need to simply add sulfuric acid or finished electrolyte. But this is a delusion because A higher concentration of acid leads to fast sulfate plates and their sprinkling . Accordingly, the battery will rapidly lose charge, and all subsequent recharging only bring it to the "death". Moreover, if the battery is long exploited with a reduced density, which indicates a decrease in the share of sulfuric acid, this is also the road to its speedy failure.

Thus, if you encountered the fact that the electrolyte density fell, the following steps must be taken:

  1. Try to find out the reason for changing this parameter - perhaps the density (and with it and the level of charge) fell due to the fact that you forgot to turn off the headlights on the night or there are current leaks;
  2. Charge completely ACB to the values ​​specified by the manufacturer and again measure the density;
  3. Carefully inspect the battery case on the availability of mechanical damage and holes.

The battery has its secrets, how to bring the density to the optimal indicators. To do this, they put the battery for a period of 12 hours to three days and charge weak currents of no more than 0.5 of the battery capacity. In this case, the density is measured at equal time intervals. Ideally, if there are no defects in the form of discontinuation of the plates and sinking the active mass of lead, the charged battery will work normally for a long time. Naturally, it will be necessary to carry out the diagnosis of the electrical circuit to detect current leaks.

Radical way to increase electrolyte density in battery

If the density fell due to the fact that an electrolytic solution was leaked, it would have to align its concentration in all banks to the old method - by draining the old liquid and fill the new one. Note that sometimes it is resorted to this method and in the case of fullying the resource and the density drop to 1 gram per see cube.

This operation is performed according to the following algorithm:

  • We make a disassembly of the battery and refer it to a well-ventilated room with an air temperature not lower than 15 degrees;
  • using a pear, pump out electrolytic fluid from each bank;
  • Fully pumping the electrolyte of a pear will not work, so the battery is placed and drilled holes in the bottom of each of the cans and drain the residues of the liquid;
  • Wash the inside of the battery with distilled water.

The drilled holes are sealed with a soldering iron or rush with a special adhesive composition based on plastic. Next, proceed to the preparation of electrolyte. You can buy a ready-made correction composition, or to pour separately, first distillate, and then acid (concentrated solution).

Please note - the order of fill must be exactly the following: first pour water, then acid. If it is broken, the chemical reaction will begin and the electrolyte will boil.

We remind you that this procedure will be appropriate only if you know exactly what an electrolyte leakage occurred or it fully developed his resource, and the battery does not hold the charge. But it will not help if sulfate occurred.

  • Shake a little battery for stirring;
  • When the composition falls a little, measure the density range - if it is within up to 1.25 and there is no difference in banks (no more than 0.1 g / cm. Cube), then you can put an acb on a short charge for two or three hours, or immediately put on the car and drive some distance;
  • If the difference between the banks is greater than 0.1, spend corrective charging.

To carry out similar manipulations, it is necessary to have charger and additional tools. In addition, working with acid is dangerous by itself: there must be good ventilation, protective glasses and gloves are required. Therefore, if you do not have experience, time or desire to delve into these technical details, it is better to turn to professionals in a car service center.

Detailed guide to an increase in electrolyte density in the battery at home

Raise the density in the battery at home can be in several ways: to completely replace the old electrolyte on a new or fill the battery charge. Both manipulations should be carried out in well-ventilated premises in compliance with safety. After completion of the procedure, you need to adjust the volume of the working solution, and then measure the density parameter by the range.

Why does the electrolyte density fall?

The main reasons for which the electrolyte level may fall in the automotive battery banks (AKB):

  1. Device device. As a rule, the discharge in the car battery occurs during the cold season, so in the winter use special methods to restore and raise the level of charge. The problem may manifest itself in a car battery, which is close to natural wear. With a rapid discharge, it can be concluded about the fall in the proportion of the working solution to a critical low level. The problem of discharge can be associated with mechanical damage to the device or a malfunction of the generator set, as a result of which the car's power grid is powered by the battery.
  2. Swinging the working fluid as a result of recharging the battery. If a constant voltage comes to the device, this leads to the separation of water to oxygen and hydrogen. As a result, when charging, the liquid rolls out and the electrolyte level decreases.
  3. Continuous addition of distilled water instead of a chemical solution. If you add the liquid once, the density level of the battery in the car should not fall, but constant advantages will contribute to this.

How to prepare a battery for recovery?

Before you restore the electrolyte density on the serving battery, you must perform a number of actions:

  1. Dismantling the battery with a car is made, for this, terminal clips of devices are pre-weakened.
  2. If you have protection, it is removed. This requires a wrench of the appropriate size.
  3. With a screwdriver or other fixture with a flat tip, unscrewing traffic jams. It is recommended to use protective glasses and gloves to prevent burns.
  4. The user performs the diagnostics of the volume of the working fluid in the device. For passenger vehicles, this parameter must be about 1.5 centimeters above the plates. The diagnosis of electrolyte density should be carried out 3 hours after recharging the device or about 10 hours after stopping the engine. If the fluid level corresponds to the norm, the areaometer is lowered into the cans and with a pear is a set of a small amount of water.
  5. Depending on the air temperature, the parameters obtained are evaluated. Check is performed for each can separately. Ideally, this indicator should range from 1.25 to 1.29 g / cm3.

When preparing the battery, it is necessary to take into account the following nuances:

  1. Before opening the cans, the user needs to clean the body of the device from pollution with pure rag. This needs to be done so that the dirt did not get inside the battery when unscrewing traffic jams. Otherwise, a complete output of the device is possible.
  2. If the diagnosis is performed without disassembling the battery, then you need to make sure it is high-quality landing. The device should not hang out.
  3. When preparing the battery can not be turned over, as this can lead to the destruction of the plates located inside. As a result, the Akb will fully fail without the possibility of recovery.

Video: ARETER MEASURE TREATMENT

The Channel "Battery" in his video described in detail the process of preparing the battery and spoke about the use of the area.

How to independently increase the density of the electrolyte?

For the correct procedure, the following nuances must be taken into account:

  1. When preparing a new working solution, acid is added to distilled water, and not vice versa. Otherwise, boiling fluid will begin.
  2. The user will need accurate calculations of the desired acid volume, since in the process of charge, the electrolyte density level increases.

On a new battery, it is not recommended to lift the electrolyte density independently, as this will lead to a faster discharge of the device. The increased working parameter will negatively affect the functionality of the battery.

The procedure is necessary in compliance with safety, since the electrolyte is nothing but acidic solution, so:

  • put on rubber gloves;
  • Mainly secure yourself from the ingress of electrolyte on clothes and the more skin;
  • Use safety glasses and respirator.

What do you need?

To correctly increase the battery density before the winter period, you need to prepare the following materials and tools:

  • hydrometer;
  • a measuring glass or other similar capacity;
  • Separate capacity for breeding a new working solution;
  • Pear enema;
  • corrective solution or acid;
  • distilled water.

Step-by-step instructions for an increase in electrolyte density by adding fluid

Proper method for increasing the battery electrolyte density parameter:

  1. Before raising the density in the battery, the battery is removed from the car. For this, terminal clamps are disconnected and the locking plate is disassembled. Actions to fulfill the task are carried out using a wrench.
  2. A small amount of working solution is selected from the battery banks. To do this, use a carometer.
  3. Instead of the exhaust volume of fluid, a correction solution of the substance is added to the bank if the density is needed. In case you need to lower this parameter, distilled water with a density of 1.00 g / cm3 is used.
  4. Then the battery is placed on recharging. Over the next 30 minutes, recharging the device with a rated current. Such actions will allow the corrective solvent to mix with the working fluid.
  5. The battery is disconnected from the charger for one or two hours. This will allow density in the banks to "align" and decrease the temperature level. Also, in two hours, all bubbles will come out of the cans, thereby eliminating the likelihood of error during the control measurement.
  6. The diagnosis of the electrolyte density level is reused, if necessary, the procedure is repeated again. Also, if necessary, liquid is added to the banks to increase or decrease the parameter, and then the measurement is re-performed.

It must be borne in mind that the difference in the density parameter between banks should be not more than 0.01 g / cm3. If when executing the task, it was not possible to achieve such a result, it is required to perform an additional charge, "leveling" charging for 1-2 hours. In this case, the current parameter must be 2-3 times less than the nominal.

Formula for calculating the amount of fluid to adjust the density of electrolyte

Where:

  • VE - the volume of the electrolyte removed from the bank, cm3;
  • Vb - electrolyte volume in one bank, cm3;
  • ρn - initial electrolyte density to adjustment, g / cm3;
  • ρk - the final density that should be obtained, g / cm3;
  • ρd is the density of the fluid being fused, (water - 1.00 g / cm3 or corrective electrolyte - * g / cm3).

When using this formula, the volume of the removed and the added electrolytes is equal.

Table: Correction of density in battery

How to raise the charger?

To increase density charger, the following actions are performed:

  1. The battery is communicated until complete charge. You must first remove the device from the car and connect to the equipment, which will charge the battery, with the polarity. First, connecting to the device, and then connect to the network.
  2. In the process of charge recovery, the user needs to follow the state of the electrolyte. After the liquid began to boil, it is necessary to reduce the power supply parameter to 1-2 amp. When boiling water, its evaporation occurs, this leads to the fact that the electrolyte concentration density begins to rise.
  3. The time of evaporation of the fluid is determined by a specific situation, in some cases it may be required for more than 24 hours.
  4. After reducing the water level in banks, electrolyte is added and the density measurement.
  5. If necessary, the repetition of this operation is made.

Density Rapip Guide in a non-servant battery

Action to increase density are performed similar, the difference is to access the working fluid:

  1. In the unworthy devices, the case is completely closed, so the user needs to dismantle the battery and remove the sticker from it. The battery cover does not need to be removed, since it will be difficult to install it.
  2. It is necessary to make a hole in the lid using awl or drill. It should be small because it will have to be seeded later.
  3. Using a disposable syringe into the battery, a distillate is added or a corrective electrolyte depending on what needs to be done with the operating parameter. 5 ml of liquid should be added. It is recommended to use the battery bank in which the density indicator is located. If the indicator has become black or green, then another 20 ml of fluid should be added to the battery.
  4. To determine the level of working solution, the needle is lowered into the jar, and the rod pulls up in the opposite direction. Tightening the working solution into the syringe, it is recommended to mark the level using the marker. If a light shade plastic is used in the battery, the liquid level can be defined on the lumen or measure using the ruler. The remaining banks are valued to the level, which should be 1.5-2 cm above the surface of the plates.
  5. After performing the task of the opening, you need to be sealing with sealant or special rubber stoppers. Then the battery should be carefully shaken to mix the electrolyte. But it is necessary to act neatly so as not to damage the plates.

How to increase the density if it is below 1,18

If the density is less than 1.18 g / cm3, the described methods will not allow solving the problem and the user will need to completely fill the acid from cans.

The algorithm of actions will be like this:

  1. The electrolyte is pumped out of the battery, as far as possible (for pumping, you can use a pear with the mud).
  2. The battery is carefully flushed without sharp movements. This will prevent possible shower of plates. In the bottom of the device, you need to drill holes in each jar with a drill. These actions are recommended to perform in the container, for example, a bowl or basin.
  3. The battery is then installed in a vertical position and remnants of the working solution merge from it.
  4. Battery washed with distillate.
  5. The openings in the bottom of the battery are sealed, at this stage it is important to make sure that the device is tightlying to prevent further fluid leakage. A new solution is filling in the battery.

Plastic for seating the hole in the battery must be maximum resistant to sulfuric acid. In addition, if the electrolyte color is brown or black, restoring the battery does not make sense. A dark shade testifies to sweeping plates or on the destruction of the battery.

The channel "Denis Mechanic" in his video outlined in detail the process of charging the battery and addition of electrolyte, as well as increasing its density.

How to increase electrolyte density in the battery?

Every driver in his life came across such a problem as a batching battery. One of the common causes of the discharge of the battery is the low density of the electrolyte. Many people do not know that it is possible to raise the density of electrolyte in the battery at home.

Why in the car battery

The word "battery" came to us from the Latin dictionary, it is translated as "Drive". In our case, the battery accumulates energy and stores it. To start the car engine, you will need a sufficiently large amount of electric current. The generator in the car can not yet produce energy, and therefore it is necessary to take it from any source. This source is the battery.

The battery serves not only to start the engine, but also to maintain certain functions of electrical appliances in the machine (for example, car alarm, which, when the engine is turned off, is powered by an electrical charge from the battery). Therefore, it is necessary to carefully follow the charge of the battery and not to allow its complete discharge.

Electrolyte in battery

The electrolyte is a substance that conducts and saves the electric current. The electrolyte includes two essential components: sulfuric acid and distilled water. One of the electrolyte parameters is its density. Measure it with an instrument called "Aareometer". Density measurement is performed at a plus temperature (22-25 ° C).

Increased electrolyte density in the battery can cause corrosion on a positive electrode and banks. But the low battery density will not bring anything good. At a minus temperature, the electrolyte with reduced density can simply freeze.

The discharged battery can contribute to a decrease in electrolyte density. So in winter it is important to carefully follow the charge of your battery. But if still the car did not start, and the battery was discharged, how to increase the electrolyte density in the battery? In this case, it is not worth running to the nearest car service. Charge the battery and raise the electrolyte density can be at home. This will require certain tools.

Required tools

To determine which electrolyte density in your car battery, you will need an areaometer. The price of such an instrument is 150-500 rubles. You can buy it in any construction or automotive store. You also use a measuring glass and a medical pear to pump out part of the electrolyte. And most importantly - you will need electrolyte and distilled water.

If the electrolyte density in the battery is completely low (we will look at this situation below), then you need such tools such as a charger, drill, soldering iron and food soda. All these items can be at home, and if there is no something, you can ask for acquaintances. Be sure to buy rubber gloves in a pharmacy or shop.

Preparation of battery

In winter, the car battery must be taken home and leave for a day in the warm room. After this time, you can check the battery charge. To do this, you need to extort the terminals with sandpaper and measure the charge with a tester or multimeter. If the battery requires recharging, then before filling the electrolyte, it should be charged it.

As soon as the battery charged, you can proceed to the density measurement. Carefully unscrew all the lids of battery cans. Lower the areaometer into each jar and type the electrolyte until the float floats. On the scale, measure the electrolyte density in the battery. Winter is a harsh test for your battery, so the density should be slightly higher than in summer - about 1.30-1.31.

We increase the density of electrolyte

So, if you measured the electrolyte density in the battery, you must proceed to the next step. First you need to know that for each region and the time of year, the density is different. The electrolyte density in the battery in the summer is approximately 1.26-1.27. In each bank, it should be the same, the variation of the maximum values ​​is allowed to be 0.01.

What electrolyte density should be in the battery, you can see the table below.

First, we pump out the electrolyte from each can with a medical pear. Try to do it as closely as possible. Next, you need to pour a new electrolyte in the volume in which it was reproached. Once all banks are ready, they should be closed and shaking a little battery.

We measure the density again. If the values ​​are still small, we repeat the procedure again, and so as long as the result is satisfactory. Distilled water is used to fill the remains of the cans after the entire procedure.

If the density is completely low

How to raise the electrolyte density in the battery, if it fell below 1.20? We will have to go to the nearest auto shop or the power tools store and buy rechargeable acid. Battery density is 1.84. The process of pouring the acid is made in the same way as the electrolyte. Be sure to work in gloves! If rechargeable acid falls on the skin, chemical burns will appear.

Full replacement of electrolyte

There are cases where the electrolyte density in the battery is too low (below 1). Then it will take full replacement. First you need to pump out the maximum possible amount of acid from cans. After that, close hermetically jars and turn the battery on the side. Drill 3-4 mm Do the hole at the bottom of each can and download the remnants of the electrolyte. Distilled water rinse the battery. Take the soldering lamp and throw holes. Seating is carried out by acid plastic, which can be taken from the old battery.

Now you can start pouring a new electrolyte, it is best to prepare it yourself. It is prepared with the help of battery acid and distilled water. Attention! Dilute by adding an acid into water, and not vice versa. It is necessary to mix until the density is a certain value (the density for each region and the season is presented in the table above).

Useful tips when choosing a battery

The battery life of the battery is an average of 3 to 5 years. With the onset of cold weather, buying a battery is the same as an important task as the purchase of winter tires. When choosing this item, it is necessary to take into account some important points.

  1. Battery capacity. It depends on the type of your car and the type of engine. Mostly for passenger cars, there is enough battery with a capacity of 55-65 am / h. Buy the current source with a higher capacity is optional, especially if the ignition and power system are set correctly.
  2. Battery type. There are two types of batteries - served and maintenance-free. In the latter, the topping of the electrolyte and distilled water will be needed 1-2 times a year. The minus is that the maintenance-free battery cannot be charged with a conventional charger. The cost of such current sources is higher than that of the serviced batteries.
  3. Exploitation. If you're going to ride off the road, then you should take a battery with high protection so that the plate is not damaged when shaking. For short-term trips, a non-listed battery is suitable, it has a speedy charge from the generator.

Operation in winter

Before the beginning of the winter season, be sure to check the battery charge and the electrolyte density. On how to raise the density of electrolyte in the battery at home, you already know. Now in the shops are sold thermokes for batteries, as well as special blankets for the carpenter of the car. To start the engine in the winter, there were no problems, the hood should be insulated. Be sure to change the engine oil, it should maintain its fluidity even at a minus temperature. Usually, synthetic oil is poured for winter (0W30, 5W40, etc.).

At temperatures below 20 degrees should not try to immediately run the engine. To begin with, turn on a few seconds of the distant light or "emergency" to enable the battery "Wake up". This will help heat the electrolyte and reproduce electrochemical processes in the battery. Do not twist the starter more than 30 seconds: first, it can burn, and secondly, you put the battery.

If you got a battery on the road

There are moments when I got a battery, and you need to go, what to do then? One of the most popular ways is to cure from another car. On both cars, the ignition should be turned off. Connect the cable first to the positive terminal of the discharged battery, the other end is on the terminal of the donor. In this way, connect another cable. Run the donor engine and let it work on revolutions for 20 minutes. Try to run the engine of your car after that.

Cables for charging may not be or given the method does not work. Then it will help the towing of the car (this method is intended only for models with manual gearbox). Towing cable should be consolidated by both cars and start moving. Turn on the second transmission and squeeze the clutch. Next, you should sharply throw the grip and click on the gas pedal. Once the car becomes necessary to give time to the engine so that the battery is charged from the generator.

Let's summarize

What density of the electrolyte should be in the battery for your region or season? This you can clarify using the table above. It is possible to increase the electrolyte density at home. But in the car service, such a service will cost 500-700 rubles. If you do it yourself, there is confidence that do everything on conscience. How to check the electrolyte density in the battery, you now know. Carefully following the instructions, you can easily perform all the work.

If you follow the health and status of your iron friend, it will never let you down and serve for a long time.

How to lift the density of electrolyte in the battery at home

Author: Maxim Markov

Good day! All blog readers know that the battery is served, requires periodic checks. After all, the concentration of sulfuric acid in it falls over time. Therefore, every self-respecting motorist should know how to raise the density of the electrolyte in the battery. About this, we and talk.

Why the electrolyte density drops

Before you understand how to increase the electrolyte density in the battery, let's find out the reasons for its fall.

For any battery, the change in density is a normal phenomenon. Those., The battery was discharged - its value decreased. Charged - rose. But in some situations, the battery simply does not hold charge. And this suggests that the concentration fell too much and it's time to raise it.

Why does the battery become a small density:

  • The battery is simply discharged;
  • The battery was reloaded, as a result of which the electrolyte was knocked out;
  • Distilled water fills in banks, and the concentration measurements are not conducted. As a result, the electrolyte density gradually falls;

By the way, if the battery will work for a long time in such a state, this will lead to sulfically plates. Therefore, it is better not to run it.

Preparation

So, if as a result of testing the range, the low electrolyte density in the battery should be lifted. But before doing it, you need to make sure that some conditions are followed:

  • Akb is charged;
  • The electrolyte temperature in banks is within 20-25 OS;
  • In all banks, the fluid level is normal;
  • Battery whole. On the battery, cracks often appear near the currents, due to the loosening of contacts. Therefore, you do not need to knock and apply unnecessary effort to remove the terminal on the battery. It is better to spend a little more time and make it carefully.

If the battery is discharged, it is charging, and after the density is measured. Why is that? The fact is that with low charge - the concentration of acid in banks is reduced.

If you pour the adjusting solution into an uncharged battery - the concentration of sulfuric acid can be increased to such an extent that the plates are crushed into banks.

It is necessary to consider, and the fact that the car generator is charged by the battery by only 85-90%. Therefore, before measurements, the charging of the battery needs to be carried out at mandatory.

Corrective recharging AKB

Sometimes, there may be a situation that after a complete charge, the electrolyte density in banks is different. In general, the difference in density is allowed not more than 0.01 kg / cm3. Otherwise, it is required to align.

To do this, you can conduct correction of the battery recharging. 2-3 times the strength of the current decreases (compared with the nominal value) and the battery charges 1-2 hours. If it did not help align the density of electrolyte - more radical measures will be required.

Corrective electrolyte

Correcting, called electrolyte with a density of 1.40 kg / cm3. Remember, in no case, you can not just pour it into the battery. Those. At first, you need to check the battery and find out the cause of the drop in the fluid level, and then raise it.

The situation is often found when novice motorists incorrectly interpret the name "corrective". For example, when water was evaporated from the cans. Those. It is necessary to raise the level of fluid, and here just a correction solution. Logic is simple:

  • electrolyte floods in battery, and its level fell;
  • The solution is adjusted, which means it is designed to adjust the fluid level.

Unfortunately, such a point of view is rooted incorrect. In most cases, distilled water pours into the battery.

A corrective electrolyte is poured in such cases:

  • If the liquid flowed out of the cans;
  • If you poured too much distillate in the battery and lowered the density.

Therefore, it does not need to pour it if, for example, the battery is simply discharged, and, accordingly, the concentration is lower than the desired one.

Raise the density of the electrolyte in the battery

So let's understand how to increase the density of the battery. I will say right away - it's not a tricky, but quite painstaking and besides, takes a lot of time. Therefore, it is better to be patient in advance.

The normal electrolyte density should be within 1.25-1.27 g / cm3. Moreover, this value should be equally for all cans. In order to raise the electrolyte concentration in the battery banks, a correction solution is used. If you want to independently prepare a mixture at home, remember the sequence:

  • Distillates pour into the container, and sulfuric acid is added to it. If you do vice versa, the solution will begin to boil violently.

Also, you will need:

  • Aerometer with a pear for pumping liquid from cans;
  • Glass tank for the drain of old electrolyte;
  • beaker ;
  • Protective glasses, gloves.

It is important to remember that the liquid can have different density in banks. Therefore, it makes sense to make a simple sign, where to make the results of measurements for each bank - otherwise you can get confused.

Immediately do one important clarification. Some comrades, advise how to raise the density in the battery, are offered to completely pour the electrolyte and pour a new one. And for this, they recommend simply turning the battery, pour the liquid and rinse with everything with distilled water. And as a result of such manipulations, one or more cans stop working.

Why is this happening? The fact is that a lead sediment is going to the bottom. And if the battery turn over - the pork pieces can fall between the plates and move them. Those. Bank ceases to work.

So, when the density of the electrolyte fell, there are several effective methods to raise it painlessly. Let's look at them.

Adjusting the corrective electrolyte

To do this, you will need a concentrated electrolyte.

How to increase density:

  • A liquid is pumped out of the bank using an aerometer or a conventional fringe;
  • Instead of it, the same amount of corrective solution is poured;
  • The battery is placed on half an hour - an hour, after which, it is maintained for 2-3 hours;
  • control measurements are carried out;
  • If necessary, the procedure is repeated.

When pumping, you need to monitor so that the surface of the plates is not taken off.

Alignment using a charger

Everything is simple here. The only condition will need a charger for a car with rigid output voltage adjustment. Automatic charging, reducing current strength when the full charge is achieved.

How to restore density:

  • Akb is communicated until complete charge;
  • When it is charged and begins to boil - the current is reduced to 1-2 amp;
  • Logic simple - battery boils, water evaporates, electrolyte concentration rises;
  • evaporation time depends on a specific case and can last more than a day;
  • when the level fell - the electrolyte fills and the density is measured;
  • If necessary - the operation is repeated.

Of the minuses, it is worth noting that it is long.

If the density is too low

How to align the density if it is too low? For example, if its value is below 1.18, the methods described will not work. We'll have to merge the acid completely.

Let's see what to do in this case:

  • The electrolyte is pumped out of cans, as far as possible;
  • The battery is neatly turned over, and the holes in each can be drilled in the bottom.
  • It is advisable to do it in some capacity, for example, in the pelvis;
  • After that, the battery is put in a vertical position, and the residues of the liquid are poured;
  • The battery is washed with distilled water;
  • Holes are searched, and a new solution is poured.

Plastic for plating holes should be resistant to sulfuric acid.

Sometimes there are situations where there is no density in old batteries. This speaks about deep sulfate. In this case, more serious measures will be required.

In fact, if the electrolyte density fell in your battery - this is not such a big problem. And it is possible to raise it without any hard work. But, only if you determine the fall in the concentration on time. If you do not follow the battery - it will simply fail.

Ways to raise the electrolyte density in the battery

Almost all car owners came across the need to raise electrolyte in the battery, when the vehicle stood for a long time and did not start. Sometimes the battery in winter can be discharged so much that the starter does not give any signs of life.

In the event that the starter does not twist under any circumstances, it is worth trying to charge the battery. If this procedure does not give an even account anything, then the problem is most likely related to a decrease in the electrolyte density in the battery.

The fact is that the electrolyte is a compound of sulfuric acid with distilled water, that is, without this catalyst, the battery will not work. The density of the electrolyte directly depends on the charge of the substance, which can be lifted or reduced.

The main reasons for reducing electrolyte density

Bay of electrolyte in battery

Often, motorists do not understand why the electrolyte density in a practically new battery is rapidly reduced. In order for inside the battery, a sufficient amount of electrolyte contains, it is necessary to periodically complement it to the norm by periodic topping the distilled water.

Learn Charging Time Your Battery

It should be related that the rate for the electrolyte density in winter and in the summer is 1.25 or 1.27 grams per cubic centimeter, but the indicator between the banks cannot be greater than 0.1.

Often the owners of the vehicle almost never measure the density of the electrolyte immediately after the liquid fastened. In the event that distilled water is poured too much, then during operation of the charger, the substance will repurchase, taking with me and electrolyte, which causes the need to raise the electrolyte density in the battery at home or in a hundred times, as shown in the video.

This should be done as soon as possible, because soon the battery will not even work even fifty percent. Improving the density of electrolyte in the battery will help return its capacity.

How to raise electrolyte density at home

In order to raise the electrolyte density at home, you should prepare an AKB by executing a few simple rules:

Measuring electrolyte density in battery

  • measure the range of electrolyte density level at a temperature of above twenty-two heat degrees;
  • mix the solution, gently adding acid into the water with a thin flowing;
  • It is necessary to use the container in which the old mixture will merge and prepare new;
  • Before raising the electrolyte density in the battery, you should measure it in both banks

In cases where it is necessary to raise the density of the electrolyte, it should be done correctly, and for this, to roll out a larger fluid to the device and measure its number. After that, the lack will be required by the same amount of a mixture of acid and distilled water, and then connect the charger to the battery at home for thirty minutes.

After the old and new mixtures were mixed, you will have to again measure the density of the electrolyte in each bank of the battery. Correctly repeat all the above will have several times, until the electrolyte level comes to normal.

Electrolyte density measurement

After the density managed to raise, the required amount of distilled water is added to each bank. By the way, if the density is after all procedures of 1.18 grams per cubic centimeter in winter or in summer, then independently raise the level at home, unfortunately, will not succeed.

It is worth trying to bring the indicators to the norm by adding non-distilled water to the battery, but acid, since its density significantly exceeds the same indicator in the electrolytic mixture.

However, most accumulators with such an indicator of electrolyte density, especially in conditions of harsh Russian winter, will not work. In order to reanimate the unit, without trying to raise the density of the electrolyte, it is necessary to tritely drain the solution completely, replacing it to a new mixture. Upon the service life of the battery will be disastrously decreased, but the car will still be able to ride before purchasing a new unit.

Increased electrolyte density using charger

Removing the battery from the car

Another way to quickly raise the battery electrolyte density in the home conditions independently, is the increase in this indicator using the charger.

This method is equally suitable for winter and summer, but only everything should be done correctly and stages:

  • Charge the battery on weak currents for a long time;
  • Make sure that the full charge is reached when the electrolytic mixture begins to boil;
  • wait for the moment when water evaporates, and the acid will fall;
  • clarify how much the electrolyte level in the battery has decreased, and add the electrolytic mixture of the required density;
  • Measure the booming level and add the required amount of electrolyte at least two days.

It is worth clarifying that it is possible to raise the density of the electrolyte in a separate battery, at home in several ways. It must be remembered that the basic safety rules should be observed in winter and in summer, that is, working with glasses and protective gloves to avoid chemical burns.

Car owners are often faced with the problem of engine failure from launch. This happens due to the discharge of the battery and deterioration of the properties of the electrolyte. Before raising the density in the battery, you need to find out the reason for the deterioration of the quality of the acidic solution. After that, you can proceed to the restoration of the battery. Actions do not represent special difficulties.

Voltage check battery

In the process of operation, a decrease in the battery density is a common phenomenon, especially when the old electrolyte is untimely replacing.

Why the electrolyte density is reduced

Factors contribute to a decrease in density:

  1. Discharge. When the charge loss is reduced and the density of the filler. In the process of charging, this parameter gradually increases. If the battery loses most of the tank, we are talking about the fall of the concentration of the acid.
  2. Long exploitation or storage under conditions of low temperatures.
  3. Switching electrolyte when reloading. If the charger supplies too high voltage, the liquid electrolyte goes into a gaseous state and is output through the holes available on the body.
  4. Frequent addition of water. Drivers add liquid to maintain a stable electrolyte level. Not everyone uses a rayometer measuring density. Together with water, acid is thrown out, which leads to a decrease in concentration.
Sulfate battery plates

An example of sulfation of a car battery plates.

Hazards low and high acid concentration

Increased electrolyte concentration causes premature battery output. Acid destroys metal plates. Even steel is sensitive to the effects based on sulfuric acid.

Low concentration leads to such problems:

  1. Sulfate. The plates appear on the plates consisting of lead sulphate. The battery becomes unable to take a charge.
  2. Increasing the frost threshold. The liquid is crystallized already at -5 ° C. Ice shifts and damages metal parts. When deforming the plates and short circuit of the capacities, the battery is not possible. At a density of 1.28 g / cm³, the electrolyte will freeze only at -58 ° C.
  3. Problems when starting the engine. This feature is most pronounced in the winter.
Densimeter and protective gloves with glasses

To verify the density of the electrolyte, they use a densimeter (right).

Checking the density of electrolyte

It is possible to determine the density of the electrolyte at home. The procedure is recommended at room temperature.

Before starting work, prepare such tools:

  1. Protective gloves, suit and glasses. The composition of the battery filler includes an acid. In case of contact with the skin, the substance causes a chemical burn. Acid couples are dangerous, so they work only in a well-ventilated room.
  2. Densimeter. The device is used to measure density. It has a glass tube with a pear and a built-in range.

Alone, the density measurement is performed as follows:

How to measure the electrolyte density densimeter

To check the electrolyte density, the end of the densimeter is immersed in the battery capacity.

  1. The battery is removed from the landing socket. The protective casing is dismantled, screwed the plugs.
  2. Check the electrolyte level. In lead-calcium batteries, the solution should close the plates by 1.5 cm.
  3. The battery is fully charged. Checking density starts 5-6 hours after completing the charging. At a normal level of electrolyte, the Densimeter tube is immersed in banks, pumping out a small amount of liquid filler.
  4. Evaluate the instrument indicators. The areaometer should float freely in solution. The contact of the device with the walls of the container is not allowed. Indications are evaluated based on ambient temperature.
  5. Check the electrolyte density in the rest of the banks. Indications are recorded and compared with normal density.

This method of checking is suitable only for the collapsible battery when there is access to the electrolyte. The maintenanceable battery is equipped with an indicator, the color of which varies depending on the density of the filler.

How to adjust the density of the solution

Normal reading lies in the range of 1.25-1.29 g / cm³. If at a temperature of + 25 ° C is a lower value, it must be raised. A drop in concentration in one of the cans indicates a short circuit.

High values ​​are detected after charging with a powerful current accompanied by boiling electrolyte. It is possible to increase the density by adding acid, refueling the finished composition or use of the charger.

Cold Solution Density

In the cold season, the density of the filler of the charged battery should be 1.27 g / cm³. Additional adjustment in the regions with a harsh climate when changing the season is not carried out.

Electrolyte density table in battery

Table of electrolyte density dependence in the battery from temperature.

Preparing for the restoration of the battery

At the preparation stage, such actions are performed:

  1. Battery charge. It is impossible to start recovery at low charge. Adding an electrolyte contributes to a sharp increase in the concentration of acid. This leads to the destruction of metal plates, in which the battery is disposed of.
  2. Normalization of electrolyte temperature. The indicator lies within + 20 ... + 25 ° C. The electrolyte level in each bank should be normal.
  3. Inspection of the battery. The case should not have cracks and chips, especially near the conclusions. Damage contributes to swaying when trying to remove the accurate terminal.

Increased electrolyte density

If the density is more than 1.18, the finished composition with the normal concentration of sulfuric acid.

The procedure includes such steps:

  1. Battery discharge. The topping of the electrolyte is carried out only with full discharge. For this, the battery is connected to a powerful lamp or other energy consumer.
  2. Preparation of the correction component. The acid level in such a means should be at least 1.4 g / cm³.
  3. Adding a corrective composition. Preliminate part of the electrolyte existing. The density of the solution should rise to 1.25. The action is performed for each bank. The volume of the fluid being fused should be no more than 50% of the died. After adding the liquid, the battery shake, giving the filler to shuffle.
  4. Battery charge. The battery is left for half an hour, which allows concentrations to align in banks. The battery is connected to the charger for 30 minutes. The strength of the current must be minimal. 2 hours after stopping charging, the density and amount of filler measure the density. If the concentration does not rise, the above actions are repeated.

Is it possible to increase the minimum density

When the density drops to a mark below 1.18, the addition of acid turns out to be ineffective. To restore the battery, a solution is used containing greater than the electrolyte, the amount of active substance.

Drain of electrolyte with battery

Before the fill of the new electrolyte old need to merge.

To replace the filler, perform such actions:

  1. Drain of content. The maximum amount of fluid roll out pear. Then the battery is placed in a large container and turn over side. In the bottom of each bank form a small hole. The battery is returned to the previous position and wait for the leakage of the liquid filler.
  2. Adding water. The liquid is poured through the covers of cans to remove the remains of the old filler. The previously made holes are closed with a polymeric material resistant to the effects of acids.
  3. Filling the battery with a new solution. If all actions are completed correctly, the battery becomes ready to use. The disadvantage of the method is to reduce the battery life. A few weeks the device will work, but then you will have to buy a new one.

How to increase with the charger

If the acid concentration fell over winter, it can be restored by supplying a weak current. Charging takes at least 3 days, it is considered effective if you cannot restore the battery with other methods. The contents of the full battery power when charging begins to boil. A sign of water evaporation is the formation of small bubbles on the surface.

Excess liquid evaporates, the acid concentration will increase. The overall level of the filler will become small, so you have to add a ready-made battery solution. After completion of the procedure use the range. If the instrument indicators are too low, charging and adding electrolyte repeat.

The design of the modern battery is checked and rechecked by time, and the bulk of instruments on the market is a compromise of technological solutions and the final cost. For this reason, classic lead - acid accumulators are so common, they are quite thought out and technologically, but they have an acceptable price.

However, such AKB requires regular maintenance and control over its condition. Checking the density of the battery electrolyte is the basis of diagnostics, it indicates the state of the battery, its ability to keep charge, ensure trouble-free start, the operation of other systems.

It is important not only to be able to independently measure the state of the electrolyte, but also know how to correctly increase the density in the battery.

Checking the density of electrolyte

The electrolyte is a solution that for the most part consists of distilled water containing 35% sulfuric acid. During operation, the density of this substance may vary.

Often indicator It falls due to the periodic addition of distilled water, which is required to maintain the optimal level. When the battery is charging, water evaporation occurs, and if the distillate content exceeds the norm, turns out and electrolyte.

In this case, the indicator may fall too low , the battery will stop working normally, engine Does not start.

Before deciding question how to increase the density in the car battery, you need right Measure it, taking into account the ambient temperature. It is better to carry out the procedure at +25 degrees.

Preparation for work:

  • Gloves and glasses for protection, clothing that is not sorry - all this is mandatory, since the composition of the working fluid there is sulfuric acid (entering the skin leads to serious burns, even pairs are able to harm the person, so the room should be well ventilated);
  • Densimeter - required to determine the density of the solution, is represented as a glass tube with a rubber tip and a pear, an areaometer is located inside.

How check is performed:

  1. The drive must be removed from the machine.
  2. If protection is provided, it is dismantled, then jams are unscrewed.
  3. Next, the amount of solution in the system is checked. For passenger models, the composition should be at the level of 1.5 cm above the plates.
  4. Important battery charge. Check start a few hours after charging It will be completed. If the level is normal, the densimeter is lowered into banks by typing a small amount of fluid.
  5. Depending on the temperature, the instrument indicators are estimated. In this case, the area should be in a calm state, floating in the solution, touching the walls of the device is not allowed.
  6. After writing the results obtained after checking each bank, you can compare them by defining the optimal density and level of charge.

Attention: Like method Suitable for collapsible models where there is an opportunity Alone Control indicators, replace the solution.

If the battery is maintenanceable, a special indicator is provided for control, which, depending on the color indicates a certain level of density, the need to increase.

How to adjust the density of the solution?

The optimal value should be in the range of 1.25-1.29 g / cm3, under normal climatic conditions, the ambient temperature is +25 degrees.

If a lower result is detected, it means that you need to increase the indicator. It sometimes it turns out that the result is only one of the cells is much lower than norm .

This indicates a defect - a short circuit that occurred between the plates. Exceeding the norm suggests that the electrolyte is boiling.

Wanting to increase car battery density at home, care must be taken.

Process plain - It will take the container where you can drain the old liquid from the drive, a scratch, a measuring glass. To restore it is better to use the finished electrolyte.

Wanting to make the solution independently, take into account the Rule - the acid is added to the water, otherwise the composition will boil.

Main steps:

  1. Announced battery, protection, unscrewing caps of cans.
  2. Next, using the scripture, you need to remove as much liquid as much as possible from all jars. At this point it is important to measure the amount of solution.
  3. To restore due Level, add corrective composition in the corresponding volume. The drive is slightly shake, so, the liquid is slightly stirred.
  4. Next, the battery is sent to recharging. This will allow the composition to be completely shuffled. After all, the device can not shake very much, completely turning over - this leads to a shower of the plates.
  5. After 30 minutes, the battery is turned off, the control is carried out after 2 hours so that there are no errors.
  6. If the required level is not restored, the procedure is repeated again.

Important: The error between the results obtained is allowed not more than 0.01 g / cm3.

Maintaining the optimal electrolyte density is extremely important for the characteristics of the drive, the capacity of the car battery depends on it.

The growth of the density leads to an increase in the capacity of the plus electrodes, while the capacity of minus decreases, especially when the temperature drops.

Also reduced electrolyte temperature can become The reason for the reduction of discharge capacity due to viscosity growth.

What should be the density of the solution in the cold period?

Increased indicators help reduce the initial life of the device. At the same time, the decrease in the indicator is accompanied by a voltage drop, which is why it is difficult wind Motor in the cold time. Thinking on what the battery density should be in the winter period, you can use a special table.

In cold areas, where the average temperature is in the limits of -30 - -15, the optimal density of the solution in the charged battery is 1.27 g / cm3.

The same parameters are installed for regions with a temperate climate, where in the winter period the averages are at level -15 - -8. For these regions, additional adjustments are not required when changing the season.

It is enough just to provide periodic check and restore the desired indicators.

Attention: In winter, monitoring the state of the electrolyte is extremely important, due to the decrease in density, not only problems with the start may occur. It is possible to freezing the solution, accompanied by the destruction of lead plates. Because of this, the device will stop working.

Often, the results are reduced to 1.18 g / cm3, which means that the freezing is possible at -15 degrees. In this case, you must first try to charge the drive efficiently.

Since constant movement for short distances does not allow the battery to warm up well, therefore it is impossible to normal charge during operation.

Gradually rechargeable The charge is lost, and with it and the desired density.

Thinking on which density should be in the winter battery, it is necessary to take into account that during the data below 1.18 g / cm3, the recovery procedure will not give the result. We will have to completely replace the electrolyte.

The main steps:

  1. Deleting the old solution, the battery is turned over on the side, which will make the hole in the bottom of each can and remove the remaining part of the composition.
  2. Then the banks are washed with distilled water, and the holes are sealed with a special plastic.
  3. Having completed manipulation, pour a new liquid.

This option is rather time consuming, the service life is reduced, but it will give the time required to buy a new device.

How to easily raise density

In the competent car owner, the battery is always charged. The knowledge of the knowledge and skills of the electrolyte density check is guaranteed no trouble when starting the engine and operation of the alarm.

The importance of the battery in the system of ensuring the functioning of the car cannot be overestimated. The engine launch itself, first of all, depends on the stable operation of the battery. One of the reasons for the sudden or late discharge of the AKB is to deviate the value of the electrolyte thickness parameter from the norm.

What should be the concentration of acid?

The density reflects the ratio of the mass fraction of sulfuric acid and distilled water in the electrolyte.

Required ratio - 1: 2. , in percent it looks like 35% / 65% . More familiar to motorists and service specialists is the measurement in grams per cubic centimeter (g / cm³).

The indicator is measured by a special device - Aareometer . Indications in the range 1.27-1.29 g / cm³ They talk about the normal density that ensures the stable operation of the battery.

Rechargeable battery is sequentially connected isolated compartments in which plates electrodes (plus and minus) are loaded. Each compartment generates such a voltage, which in sum is about 12 volts.

Why falls saturation of the solution in the battery

Changes in the concentration of electrolyte during the use of AKB naturally. The main causes of the drop value of the parameter are:

  1. Evaporation of solution as a result of boiling, which can occur with a long charge;
  2. Looking for fluid through traffic jams on the body when the car is operated on the roads with Ughabs or off-road;
  3. Dewding AKB which leads to the sedimentation of sulfuric acid on the plates ( Sulfation )

Consider in detail Why density falls:

Evaporation of electrolyte. This is usually a long process that a long time allows the battery to work, providing a power of power, but it can be rapid, in the event of a liquid boiling.

The battery for most cars is located next to the engine. The device's heating occurs naturally during engine operation. In the summer, when the ambient temperature contributes to the speedy evaporation of fluids, the electrolyte density weekly should be checked.

When evaporated with sufficient action is the topping of distilled water into the banks of the battery, since only water can evaporate. Mandatory should be the procedure for mixing added water with a solution of acid available in banks. It is extremely important this process becomes in the period of cold weather when water can freeze.

How to level the proportions at home?

Every driver in his life came across such a problem as a batching battery. One of the common causes of the discharge of the battery is the low density of the electrolyte. Many people do not know that it is possible to raise the density of electrolyte in the battery at home.

Why in the car battery

The word "battery" came to us from the Latin dictionary, it is translated as "Drive". In our case, the battery accumulates energy and stores it.

To start the car engine, you will need a sufficiently large amount of electric current.

The generator in the car can not yet produce energy, and therefore it is necessary to take it from any source. This source is the battery.

The battery serves not only to start the engine, but also to maintain certain functions of electrical appliances in the machine (for example, car alarm, which, when the engine is turned off, is powered by an electrical charge from the battery). Therefore, it is necessary to carefully follow the charge of the battery and not to allow its complete discharge.

Electrolyte in battery

The electrolyte is a substance that conducts and saves the electric current. The electrolyte includes two essential components: sulfuric acid and distilled water. One of the electrolyte parameters is its density. Measure it with an instrument called "Aareometer". Density measurement is performed at a plus temperature (22-25 ° C).

Increased electrolyte density in the battery can cause corrosion on a positive electrode and banks. But the low battery density will not bring anything good. At a minus temperature, the electrolyte with reduced density can simply freeze.

  • The discharged battery can contribute to a decrease in electrolyte density. So in winter it is important to carefully follow the charge of your battery.
  • But if still the car did not start, and the battery was discharged, how to increase the electrolyte density in the battery? In this case, it is not worth running to the nearest car service.

Charge the battery and raise the electrolyte density can be at home. This will require certain tools.

Required tools

To determine which electrolyte density in your car battery, you will need an areaometer. The price of such an instrument is 150-500 rubles. You can buy it in any construction or automotive store. You also use a measuring glass and a medical pear to pump out part of the electrolyte. And most importantly - you will need electrolyte and distilled water.

If the electrolyte density in the battery is completely low (we will look at this situation below), then you need such tools such as a charger, drill, soldering iron and food soda. All these items can be at home, and if there is no something, you can ask for acquaintances. Be sure to buy rubber gloves in a pharmacy or shop.

Preparation of battery

In winter, the car battery must be taken home and leave for a day in the warm room. After this time, you can check the battery charge. To do this, you need to extort the terminals with sandpaper and measure the charge with a tester or multimeter. If the battery requires recharging, then before filling the electrolyte, it should be charged it.

As soon as the battery charged, you can proceed to the density measurement. Carefully unscrew all the lids of battery cans.

Lower the areaometer into each jar and type the electrolyte until the float floats. On the scale, measure the electrolyte density in the battery.

Winter is a harsh test for your battery, so the density should be slightly higher than in summer - about 1.30-1.31.

We increase the density of electrolyte

So, if you measured the electrolyte density in the battery, you must proceed to the next step. First you need to know that for each region and the time of year, the density is different. The electrolyte density in the battery in the summer is approximately 1.26-1.27. In each bank, it should be the same, the variation of the maximum values ​​is allowed to be 0.01.

What electrolyte density should be in the battery, you can see the table below.

Electrolyte density in battery

Areas and seasons The density of the flooded electrolyte Electrolyte density charged battery
Summer 1.25 1.27
Winter 1.28. 1.30
Northern District 1.28. 1.30
Southern District 1.24. 1.26.

First, we pump out the electrolyte from each can with a medical pear. Try to do it as closely as possible. Next, you need to pour a new electrolyte in the volume in which it was reproached. Once all banks are ready, they should be closed and shaking a little battery.

We measure the density again. If the values ​​are still small, we repeat the procedure again, and so as long as the result is satisfactory. Distilled water is used to fill the remains of the cans after the entire procedure.

If the density is completely low

How to raise the electrolyte density in the battery, if it fell below 1.20? We will have to go to the nearest auto shop or the power tools store and buy rechargeable acid.

Battery density is 1.84. The process of pouring the acid is made in the same way as the electrolyte.

Be sure to work in gloves! If rechargeable acid falls on the skin, chemical burns will appear.

Full replacement of electrolyte

There are cases where the electrolyte density in the battery is too low (below 1). Then it will take full replacement. First you need to pump out the maximum possible amount of acid from cans. After that, close hermetically jars and turn the battery on the side.

Drill 3-4 mm Do the hole at the bottom of each can and download the remnants of the electrolyte. Distilled water rinse the battery. Take the soldering lamp and throw holes. Seating is carried out by acid plastic, which can be taken from the old battery.

Now you can start pouring a new electrolyte, it is best to prepare it yourself. It is prepared with the help of battery acid and distilled water. Attention! Dilute by adding an acid into water, and not vice versa. It is necessary to mix until the density is a certain value (the density for each region and the season is presented in the table above).

Useful tips when choosing a battery

The battery life of the battery is an average of 3 to 5 years. With the onset of cold weather, buying a battery is the same as an important task as the purchase of winter tires. When choosing this item, it is necessary to take into account some important points.

  1. Battery capacity. It depends on the type of your car and the type of engine. Mostly for passenger cars, there is enough battery with a capacity of 55-65 am / h. Buy the current source with a higher capacity is optional, especially if the ignition and power system are set correctly.
  2. Battery type. There are two types of batteries - served and maintenance-free. In the latter, the topping of the electrolyte and distilled water will be needed 1-2 times a year. The minus is that the maintenance-free battery cannot be charged with a conventional charger. The cost of such current sources is higher than that of the serviced batteries.
  3. Exploitation. If you're going to ride off the road, then you should take a battery with high protection so that the plate is not damaged when shaking. For short-term trips, a non-listed battery is suitable, it has a speedy charge from the generator.

Operation in winter

Before the beginning of the winter season, be sure to check the battery charge and the electrolyte density. On how to raise the density of electrolyte in the battery at home, you already know.

Now in the shops are sold thermokes for batteries, as well as special blankets for the carpenter of the car. To start the engine in the winter, there were no problems, the hood should be insulated.

Be sure to change the engine oil, it should maintain its fluidity even at a minus temperature. Usually, synthetic oil is poured for winter (0W30, 5W40, etc.).

At temperatures below 20 degrees should not try to immediately run the engine. To begin with, turn on a few seconds of the distant light or "emergency" to enable the battery "Wake up".

This will help heat the electrolyte and reproduce electrochemical processes in the battery. Do not twist the starter more than 30 seconds: first, it can burn, and secondly, you put the battery.

If you got a battery on the road

There are moments when I got a battery, and you need to go, what to do then? One of the most popular ways is to cure from another car. On both cars, the ignition should be turned off.

Connect the cable first to the positive terminal of the discharged battery, the other end is on the terminal of the donor. In this way, connect another cable. Run the donor engine and let it work on revolutions for 20 minutes.

Try to run the engine of your car after that.

Cables for charging may not be or given the method does not work. Then it will help the towing of the car (this method is intended only for models with manual gearbox).

  • Towing cable should be consolidated by both cars and start moving. Turn on the second transmission and squeeze the clutch. Next, you should sharply throw the grip and click on the gas pedal.
  • Once the car becomes necessary to give time to the engine so that the battery is charged from the generator.
  • What density of the electrolyte should be in the battery for your region or season? This you can clarify using the table above. It is possible to increase the electrolyte density at home.

But in the car service, such a service will cost 500-700 rubles. If you do it yourself, there is confidence that do everything on conscience. How to check the electrolyte density in the battery, you now know.

Carefully following the instructions, you can easily perform all the work.

If you follow the health and status of your iron friend, it will never let you down and serve for a long time.

Is it possible to raise the density in the non-servant battery?

Often car owners face the engine launch problem, which is relevant after a long parking lot in winter. The reason for this is the hittered battery.

As an alternative to buying a new, many car owners with the help of a recharge device are trying to correct the situation, but it does not always lead to a positive result.

Even charging the battery for a long time does not always help, since the battery density has not been raised when charging.

When such a problem arises, it is obvious that the density decreased in the battery electrolyte. Let's look more in more detail how to raise the electrolyte density in the battery and what to do.

Why the electrolyte density is reduced

Before, playing recovery, we find out how to correctly raise the density of the battery and find the reasons that led to the fall of this indicator. In any automotive battery, this value is not static.

It is constantly changing and it is normal. When the battery is discharged, the electrolyte density is reduced. When charged, then this parameter goes up.

If a quick discharge occurs, this indicates that the concentration fell to a critical level.

You can list several of the main reasons due to which the low electrolyte density in the battery is formed:

  • prolonged exposure of low temperatures;
  • swallowing electrolyte as a result of recharging the battery;
  • Permanent fostering of water.

As for the third point, it is very often to maintain the fluid level, fill the distilled water of the battery. Mandatory condition is a regular density check. Simultaneously with water, electrolyte rolls out, which, as a result, leads to a decrease. In addition to the recharge device, it is also important to have a carometer to verify the density value.

Preparing for the restoration of the battery

Before raising the density in the battery, we will measure it with a carometer. It should be done separately for each of the cans. As for the normal level, here the range must be from 1.25 to 1.29.

Such a scatter is explained by the fact that in the regions where cold winters, it is better to keep an elevated electrolyte rate, and in regions with a temperate climate just below.

If the indicator is below the value of 1.25, it is possible to restore the normal level using the topping.

Increased electrolyte density

To raise the density of the battery, you should start with the following:

  1. You should make sure that the battery is charged. If the battery is discharged, then you need to recharge and carry out the measurement of density. It is impossible to start working if the battery has a low charge, since, in the bay of the corrective solution, the H2SO4 concentration can sharply climb into the battery. As a result - complete destruction in the cans of plates, after which, the battery can only be disposed of.
  2. The electrolyte in the battery must have a temperature of at least 20, but not more than 25 degrees Celsius.
  3. In each bank, the level should be normal.
  4. The battery should not have cracks and damage, especially near the current. Often there is a problem to remove the terminal due to the fact that it is accurate or tightly spinning. Some owners begin to draft and knock on the current and terminal, which can the integrity of the battery.

At a level of not lower than 1.18, the electrolyte topped with a normal density should be performed to increase at least 1.25. The topping is performed for each can separately. Through the enema, the pear is taken by the fence of the old, the level is measured and fastened the fresh volume of no more than half from the reputable one. After that, it should be a little shake acb to give fluid the ability to move as much as possible.

Is it possible to increase the minimum density

What if the level fell below 1.18? It is necessary to take more serious steps, because, the topping is not to do. In such cases, the accumulator acid is used. Its main difference in greater density (approximately 1.84). The work itself is made according to the same scheme as the addition of electrolyte.

Usually, after one replacement, it is possible to achieve a normal concentration, but if measurements show that the density is lower necessary, then you should repeat the operation again. This acid is for sale in any automata, so it will not be possible to acquire it. Opening with acid should be opened in an outdoor or in air and necessarily in gloves.

Acid hit to unprotected parts of the body threatens the appearance of thermal burns.

How to increase with the charger

Another way to restore the performance of the battery, recharging it on a weak current. This method requires a lot of time, but rather effective if the electrolyte density is not raised to a normal level.

  • The essence of the method is such that the battery can be independently, through the recharge device, charge to full. When the charge is maximum, the liquid will begin to boil.
  • A sign of complete recharging will be the appearance of small bubbles (there is evaporation of distilled water in the battery). Excess water will evaporate, and the acid will remain. Simultaneously decreases the overall level of electrolyte. Now you can add the new density required.
  • After that, the testimony should be measured with a steamer and if they are not sufficient, then repeat the entire procedure until the norm is not lower than 1.25 g / cm3.

If the question of buying a new or restore the existing battery, then of course it is cheaper to choose the second, especially since the work is not difficult and reading the article carefully, even a person who does not understand the technique, can easily be able to improve the density of electrolyte and recovery The performance of the battery, at least a couple of seasons. It is a serious budget economy, especially since a high-quality battery costs considerable money.

Proper replacement of electrolyte

Car batteries are created not only for starting the engine, but also to power the electrical devices of the machine at the moment when the ignition is turned off. By inattention, the driver can easily forget about the headers or a working magnetol included in the car, the volume of which is reduced to zero.

Returning to the car the next day, it can be found that it does not start, and the reason for the extext power supply. You can start the machine with a discharged battery, but after two, the emergency engine start-up methods begin to bother, and it is clearly the need to return the battery to the operating state.

"Battery density" or a ratio of sulfuric acid and water in electrolyte

In common, such a term is distributed as "battery density". In fact, it is erroneous because no one measures the density of the power supply directly.

Any car amateur will say that under the concept of "battery density" is meant the density of the electrolyte, which is covered in the battery.

It is from the density of the electrolyte in the battery, it depends on its ability to charge and maintain the accumulated energy.

If the battery was discharged by the driver's carelessness or other reasons, you should try to return to it a working state with the help of a charger. Before charging the battery, distilled distilled water, which could evaporate during the operation of the power supply.

The water in the battery is mixed with the finished electrolyte, which leads to a decrease in its density, that is, to a decrease in the percentage of sulfuric acid in the final solution. After some time, the electrolyte density in the battery, due to the constant dilution of it with distilled water, decreases, and falls below the comfortable level.

The exploitation of the battery becomes impossible, and in such situations there is a need to increase the density of electrolyte in the battery.

How to raise electrolyte density in the battery yourself?

The density of the battery, and even more precisely, the electrolyte in it, it is possible to raise quite simple without contacting the specialists of the service center. First of all, it is necessary to hold a number of preparatory procedures:

  • Prepare the containers that will need to drain the part of the old battery electrolyte;
  • Get your personal protective equipment - gloves, glasses, clothing (which is not scary to spoil). Remember: the electrolyte of the battery partially consists of sulfuric acid, which is dangerous, and when it can cause a burn, and clothing is seriously spoiled;
  • Take the tools that you will need to raise the electrolyte density in the battery: a rayometer, a pear enema, a measuring glass, a funnel;
  • Buy the necessary consumables: distilled water, rechargeable acid or finished electrolyte.

To raise the density of electrolyte in the battery, you will have to independently replace the entire electrolyte, which is already covered in the battery, to a new solution. It is quite simple to do, if you fulfill everything according to the instructions and comply with the necessary precautions.

How to change the electrolyte in the battery?

Most modern batteries are issued in collapsible, and they provide for the possibility of replacing electrolyte independently.

Inspection batteries are rare, and it is impossible to unscrew the tubes if necessary to remove the old electrolyte and fill the new.

If you wish, you can pour the electrolyte and in an unintebled battery, but for this it is necessary in each bank using the drill to do the hole. After replacing the electrolyte, plastic is attacked in the place of the holes, and the battery becomes workers again.

The electrolyte replacement itself is quite simple, and it consists of the following items:

  • First of all, it is necessary to remove the battery from the car and find a suitable place to replace the electrolyte in it and charging;
  • Next, you need to remove the protection from the battery, if it is available, and unscrew the tubes with cans;
  • After that, we take the punch enema and insert her end into one of the battery cans. Using this rubber device, pump the old electrolyte from the battery and drain it into a pre-prepared container.

Attention: In no case do not pour the electrolyte to the ground, if you perform work on the street;

  • Pulling almost the entire old electrolyte from all cans, it is necessary to clean the battery plate from its residues. This can be done with distilled water, which will not cause unwanted reactions inside the battery. To do this, distilled water is poured into each bank of the battery, after which it raises and shake. Well hold the battery so that in the process of shaking it does not fall. After that, we drain the resulting solution.

It is worth noting that some motorists are recommended for the "purity" of the future electrolyte in the battery not only to rinse it with distilled water, but also use various solutions. For example, it is recommended to pour water with soda water into the battery and leave it there for 4 hours. After that, it is also recommended to pour an hour in the battery to the battery.

  1. Cleaning the battery banks from the old electrolyte, you need to pour a new one. Well, if you purchased the finished electrolyte in the store, then it is enough to pour it with a turn to the specified faces into each jar. If you have accumulatory acid and distilled water, it is required to pre-make the electrolyte solution with a density of 1.27-1.28 grams per centimeter cubic;
  2. After that, we close the banks and begin the battery charging process;
  3. Replacing the electrolyte in the battery, it is necessary to perform the battery charging process over the "Charging-Dewding" cycle with no more than 0.1 amp until the battery density (electrolyte density) does not reach the working values.

Attention: Charging can be finished and start using the battery only after the battery terminals are performed to measure 14 volts.

If you decide to change the electrolyte in the battery yourself, we strongly recommend complying with all precautions. Acid medium, which is an electrolyte, is harmful not only if the skin is hit, but also in the respiratory tract. The electrolyte should be changed solely in well-ventilated rooms with marginal caution.

Proper proportion in electrolyte

During the operation of vehicles, drivers often face the situation when the car starter does not spin from the battery, the rotational speed of the crankshaft from the starter is insufficient to start the engine, etc. In other words, the battery is strongly discharged.

A not less common situation is that the battery is fully charged from the charger quickly discharged, with a re-charging (even taking into account the compliance with all rules and recommendations regarding how to charge the battery) to eliminate the problem still fails.

It should be noted that the density of the electrolyte and the discharge of the battery are interconnected. The electrolyte is one of the main components in the battery device, allowing you to accumulate and hold the charge.

It turns out exactly the low density of the electrolyte in the battery after charging does not allow the battery to save the accumulated energy, also the charge is not restored from the automotive generator after installing the battery on the car.

If this happened, then the element requires maintenance that involves aligning the electrolyte density in the battery or its complete replacement. Note that in some cases it is enough to restore the performance of the battery that the electrolyte density in the banks of the battery is given normal.

In this article, we will look at why density decreases, as and what is measured by the electrolyte density in the battery. We will also talk about what to do to the driver if a small density of electrolyte was discovered during measurements in the battery.

The electrolyte density fell in the battery: the reason and consequences

As a rule, the decrease in density occurs as a result of evaporation of the aqueous-acid solution in the AcB sections. In this case, we are talking about boiling electrolyte in banks, which occurs when recharging the battery. Also, water is gradually evaporated from the battery and for natural reasons, while the process proceeds slowly, allowing the battery for a long time to maintain a working state.

  • Taking into account the foregoing, it becomes clear why those serviced by AKB are needed. Access to banks allows you to control the level of electrolyte. Often this level is maintained in the specified limits by the plot of distilled water. Many auto owners are familiar with this process.
  • However, not everyone understands that the problem is alone, the problem is possible to solve far in all cases, since the density of the resulting solution is required in parallel. The fact is that together with water, the electrolyte itself is partially evaporated. For this reason, it is necessary to attach not only water, but also an electrolytic solution.
  • After compulsory, the electrolyte density is measured in the battery with a rayometer. It should be borne in mind that the correct density of the electrolyte in the battery will not only effectively accumulate and hold the charge, but also keeps the bottle of freezing with the onset of cold weather.

In practice, this means that if the driver regularly poured into the banks only water and did not follow the density of the solution, then in winter such a battery can freeze and / or fail.

The fact is that when in the winter period, the temperature of the battery electrolyte in the sections is decreased, and the solution itself is not sufficiently dense, then the water in its composition turns into ice.

It is quite obvious that the summer or winter density of electrolyte in the battery is a relative concept.

It is necessary to constantly maintain the recommended density indicator regardless of the season. Also, the density for regions with a cold climate can be somewhat increased, while leaving the value within the permissible indicators, that is, without exceeding.

It is also important to understand that the minimum electrolyte density in the battery may not cause problems in the warm season, however, with the onset of cold weather, the battery fails even at a normal level of the solution in banks. Also note that the electrolyte in the battery can turn or poisoned. In this case, it helps its replacement, in the process of which density is also regulated.

How to properly raise the density of electrolyte in the battery

As can be seen, the need to increase the battery density may occur for various reasons. First of all, you need to figure out which density electrolyte pour into the battery in one way or another. Please note that the solutions are presented on sale, the density of which is initially somewhat overestimated.

This means that during the adjustment process to reduce the density, distilled water may be needed. It should be borne in mind that the bay of ordinary flow water, technical water, etc. is not allowed. So, we go further. To determine which density is necessary, we recommend to familiarize yourself with the electrolyte density table (see above).

The next step will be the preparation of the necessary devices, tools and basic components to create a solution:

  • hydrometer;
  • glass (measured);
  • Capacity for drain;
  • rubber pear;
  • distilled water;
  • Rechargeable electrolyte;

Before starting work, note that the performance of acid operations involves compliance with safety. To protect the skin and eye, it is advisable to use rubber gloves and safety glasses.

Also in cases where the electrolyte solution is divorced independently, it is forbidden to add water to acid! It is necessary to fill the water at first, after which the acid is neatly and carefully and carefully! This will avoid injury and chemical burns.

If a complete replacement of the electrolyte is performed or it is necessary to drain the fluid, it is forbidden to turn over or tilted the battery. The fact is that such actions can lead to squeezing lead plates, after which the short circuit occurs and the battery fails.

As for the measurements of density, it is necessary to measure the measurements when the outdoor temperature will be at about 20 degrees Celsius. It turns out if it's cold on the street, the battery must first put into the heated room and give it the opportunity to warm up.

It is also important to remember that the battery density drops with a discharge and rises after charging. For this reason, to obtain the most reliable indicators before measurements, you need to fully charge the battery.

If there is no possibility to replace the battery, while in the presence of a battery type (i.e., work is made with a non-servant battery), then to gain access to banks, it will be necessary to drill in the housing of the holes using a drill. You also need to make a soldering iron for further sealing cans.

Plastic that will be used for a sealing should be resistant to the effects of acid.

To drain the old electrolyte or collecting it, it is necessary to prepare a container in advance. Glass jars or bottles are best suited for such purposes. It will also be necessary to take care of further disposal.

It is forbidden to pour the electrolyte into the sewer, merge on the ground or in the reservoirs!

Acid solution must first neutralize alkali. If you do not have certain skills, then you need to consult in advance with specialists, to study the question of profile forums, contact a similar question to the items of reception of old batteries, etc.

After all the nuances were taken into account, you can go to the battery maintenance. Next, we consider the process on the example of an acid battery. We note that if an alkaline type AKB, then some indicators will differ from those below.

How to increase electrolyte density

So, the density is measured in grams per centimeter cubic, that is, g / cm3. Density measurements need to be produced in each bank of the battery. The density of the solution must be from 1.25 to 1.29.

The scatter of the indicators by battery sections should not be above the mark of 0.01. In cases where the indicator fell about 1.20, then it is possible to raise density in banks by topping the electrolyte, which has a density of 1.27.

To implement the task, you will need to perform the following actions:

  • The topping is made in each individual bank. For this, a pear from the bank is reaping as much old electrolyte as possible.
  • The electrolyte is then merged into a measuring glass, which allows you to measure its number.
  • Further, fresh electrolyte is poured into the jar, and we need to pour only ½ from the volume that was previously dumped.
  • Next, the battery needs to be shoved from side to side, not allowing strong slopes and turning. Such actions will allow mixing the remaining fluid into the battery with fresh.
  • Now you can measure density. In the case when the value does not reach the desired indicator, you can add another half of the volume that was previously dumped.
  • Such actions are repeated until the desired density indicator is reached.
  • After the density came to normal, it is necessary to add distilled water in terms of the level, then proceed to work with another bank.

If the density in the battery is reduced to 1.18, then no electrolyte must be addressed, but a battery acid. The density of such acid is much higher. In cases where the density cannot immediately manage, the process is repeated until it is possible to get the desired value.

When working with all AcB sections is complete, the battery can be charged.

After charging the battery, the electrolyte density is again dimly, if necessary, the indicator is adjusted using distilled water or electrolyte.

Tips and recommendations

In some cases, you can face the situation when the electrolyte density is initially very low, and after the topping it is not possible to increase it. Also electrolyte gray, black, turbid or redhead in one can or immediately in all sections. This indicates the need to complete fluid replacement.

  1. To replace the electrolyte, a pear need to completely remove the liquid from the cans.
  2. Next, you will need to close the control ventilation plugs on sections.
  3. After that, the battery is put on the side or supports.
  4. Then, in the bottom of each section, a small hole is drilled alternately (diameter 3-5 mm).
  5. Through the specified holes in a predetermined container, the electrolyte remained in the battery case.
  6. Then the plugs are unscrewed, the banks are thoroughly washed with distilled water.
  7. The next step is to be sealed with plastic holes, resistant to the effects of acid.
  8. Next, you can pour into the batter of fresh electrolyte, repeating the steps described above to adjust the density of the solution.

Finally, add that in some cases such operations allow you to restore the performance of the battery for a sufficiently long term, but this is not always happening. Certain chemical processes in the battery, as well as gradual squeezing of the plates, leads to the fact that even after a complete replacement of the electrolyte, the battery may not keep charge.

If, after all the work done, the density of the liquid still falls quickly or does not rise after charging until the desired values, then it is worth thinking about replacing the battery.

Also, the driver may notice that in the process of operation of the battery, the fresh solution is black again, it becomes muddy, throws out (taking into account the fact that the battery is correctly charged from the memory, as well as the car, the generator and the relay-regulator are working on the car), then such a battery is required to be replaced.

Is it possible to top up the electrolyte in the battery at low density?

A variety of motorists are familiar with such a problem as fast battery discharge even in the absence of high load.

There are very difficult cases - the battery charged today, tomorrow, becomes completely discharged and it is detected during an attempt to start the engine.

The motorist charges the battery 100%, but tomorrow it is half lowered again.

How to solve this problem? Buying a new battery is not noone, but the replacement objectively requires not in each case, sometimes enough density check and electrolyte topping.

Many car owners causing how appropriate addition to the electrolyte in the battery under insufficient density. Perhaps it is better to replace? Consider different situations to find out how best to act in one way or another.

When the electrolyte topping in the battery is more appropriate than the replacement of the battery?

The electrolyte components of any acb are acid and distilled water. These fluids form a mixture, in which water prevails, while the acids are much smaller. For example, you need an electrolyte whose density should be 1.28 g / cube. See in this case in 1 l of distilled water, it is necessary to pour 0.36 liters of acid. The proportion will be approximately 1: 3.

For safety requires an acid in water, but in no case on turnover! Since otherwise there is a high risk of a chemical reaction, accompanied by heat release and splashing. Eating accumulator to the skin leads to strong burns. The reason for this is a lower density of water compared to acid, as a result of which these liquids are mixed extremely slow.

The volume proportion of water and acid is found with the help of an area. This device determines the density of the liquid. After decreasing the density of the electrolyte to a certain value, it is not well kept well the charge. At density slightly lower than the desired 1.3 g / cubic cm, the electrolyte should be addressed.

Changing the density of the electrolyte depends on the battery charge. For this reason, the accurate density of the battery liquid is possible only when the battery is 100% charged. How to charge the battery you can read in a separate article.

Low electrolyte density - how to solve the problem?

If the battery does not hold the charge, is it necessary to replace it? Is the electrolyte topping appropriate in case of insufficient density? Or does it still not allow to restore the performance of the battery? Here everything is determined by the age of the battery, as well as the rates of the area.

In the case when the battery is quite old (four years or more), the loss of the ability to hold the charge is primarily caused not by the disadvantage of the electrolyte density, but the destruction of the rechargeable cans.

In such a situation, even the restoration of the previous level of electrolyte density will not help. But in the case of a comparative freshness of the battery, the solution is possible by adding electrolyte.

However, it is not always necessary to pour it.

The average density of this fluid in a working battery is 1.25 to 1.3 g / cube. See it is necessary that this value is approximately the same in all battery cans. The maximum allowable deviation is 0.03. In the case when the density is below 1.25, but above 1.20, the electrolyte will be eliminated by the problem.

Liquid density less than 1.2 g / cube. cm

Is it possible to add electrolyte in this case?

Answer: Yes. However, this way will not be able to achieve the restoration of the battery performance, since when the electrolyte is topped up, the density of up to 1.25 g / cube will not exit. cm.

At a density in the range 1 ... 1.2, it is advisable to add battery acid, since its density is much higher than the electrolyte density.

Liquid density less than 1 g / cube. cm

When the area is shown the electrolyte density of less than 1 g / cube. See, even an acid topping will not solve the problem. But in the case when it is impossible to replace the battery, you can try to replace the electrolyte.

To perform this operation, it is required to pump out of all battery cans with a pear of the maximum possible volume of the liquid, followed by laying its side. Then drill small holes in the bottoms of all battery cans, the diameter of each of which should be three to five mm. Rinse the cans with distilled water.

After that, the holes can be sought (there is a plastic sustainable, resistant to the effects of acids, it is first recommended to check its reaction to the electrolyte) and pour into all banks a new electrolyte.

However, even if this operation, the AKB will not be long, since the operation time is determined by many factors.

After complete drainage of electrolyte, rechargeable cans for some time have contacts with oxygen, as a result of which rapid corrosion begins.

For this reason, a long time to operate the battery after complete replacement of the electrolyte is undesirable, it is better to replace the battery at the first opportunity that appeared.

When to lift the electrolyte density in the battery?

It often happens that already after a day after the car downtime, the engine becomes impossible - it does not twist the starter. It turns out that during this short period of time, the battery has time to discharge. In this case, the battery charging for quite a long time does not help.

Such symptoms say that the electrolyte density fell in the battery. This can happen due to evaporation of the solution, for example, because of its boiling when recharging (so that in the future, to exclude boiling when charging, read the article how to charge the auto battery correctly).

To maintain the level of fluid into the battery, it is usually topped with distilled water. After that, few people comes to check the density of the solution. And since the electrolyteok, the electrolyte is swollen with water, then this process leads to a gradual decrease in density.

As a result, after some time, its value becomes below critical.

And here is a natural question: how to increase the density of the battery? Following the instructions below, you can make sure that you can restore the battery yourself in the presence of the necessary tool and "direct hands".

Before starting to work

Measure the battery density at air temperature 20-22s. Be maximally carefully when working with electrolyte (especially with acid), use safety glasses and rubber gloves. Chemistry lessons at school.

If you breed the electrolyte yourself, be sure to add acid into water, and not vice versa! Due to the difference in the density of both liquids, you can get serious burns. Do not turn the battery upside down. This can lead to a sprinkling of the active surface of the plates and short circuit. The complex under the drain of the old electrolyte and for breeding fresh should be prepared in advance.

Remember that the density of the charged battery increases. Check the plastic-used plastic holes to the chemical resistance with respect to the electrolyte.

The procedures described below and the reduced density values ​​of the electrolyte are acidic batteries, in an alkaline battery, these quantities are different.

Required tool

The device for measuring the density of the liquid meterometer (the device for measuring the density of liquids); a measuring glass; murrass (can be purchased in a pharmacy); electrolyte; distilled water; rechargeable acid; solution of food soda; soldering iron; drill.

The reduced or elevated electrolyte density in the battery reduces the efficiency of the battery and accelerates its wear. Therefore, it is periodically necessary to measure this indicator and in the case of deviations from the norm, to adjust. We will analyze in detail how to do it.

How and how to check the electrolyte density for batteries

The norm is considered to be an indicator of 1.27 grams per cubic centimeter. Measurements are carried out by a special diagnostic tool - a steeometer. It is important that it be qualitatively manufactured and showing accurate results. A good and inexpensive device is the RedMark Areometer in a tube. It can be used to check electrolyte and antifreeze.

46-980-78976.jpg.

Here are a few rules to follow:

  • Measurements need to be carried out with a fully charged battery.
  • Check each bank.
  • The air temperature should be 20-25 degrees of heat.

Taking into account the last item, the question may arise how to increase the electrolyte density in the battery in the winter. If the car is not in the warm garage, you will have to remove the battery and put it home. Fully charge and only then check every jar.

How to raise electrolyte density in a car battery

Before proceeding to work, we prepare everything you need. It is important to remember that this liquid is a compound, dangerous for a person. His getting into open areas of the skin can cause severe chemical burns. Therefore, it is necessary to work in protective rubber gloves. In addition, you will need:

  • hydrometer;
  • glass container;
  • corrective electrolyte;
  • distilled water.

4545-09-9098.jpg

The essence of the work is to pump out part of the liquid from the battery and replacing it with a corrective electrolyte. For pumping, you can use a carometer. We recruit liquid from battery cans and drain it in a pre-prepared container.

When pumping it, it is important to remember that the battery plates cannot be pulled. It is necessary that they all the time are covered with liquid.

Many car owners are wondering what kind of corrective electrolyte for batteries to buy? A good option is "DRECO", having a density of 1.3 g / cm3. With it, we give the indicators of each bank to normal.

You ask, what will happen if you move? Parameters 1.28-1.29 g / cm3 is an increased electrolyte density, which in a new battery must be reduced. Just add distilled water. Use the usual from under Crane, it is impossible.

Summary

A quick discharge and a weak starting current is not always suggested that the battery is time to change. It is possible that the reason for inefficient work lies precisely at low density. To solve the problem, it is enough to buy an electrolyte for batteries, having an increased concentration, and with it to bring the indicators to normal.

Hello, dear friends!

On the Internet there is a lot of videos about how to restore the old battery, almost to the state of the new one. How to raise density for the winter and so on.

How to raise the density in the battery for the winter period, so as not to spoil it, told my friend the battery

The most interesting thing is that a lot of vidos can not help restore your battery, but on the contrary "finish it."

For example, I watched a material in which a person proposes to restore the battery in which the sulfate plates occurred, with the help of soda.

How to raise the density in the battery for the winter period, so as not to spoil it, told my friend the battery

Friends. When I showed this video to my friend, a battery with a lot of experience, he laughed and said that it was impossible to do so.

Also, some "scientists" are advised at a low level of electrolyte density add this very electrolyte. So it is also impossible to do, as it may later lead to too high density level.

Electrolyte is added to the battery in the event that there was a leakage. If the liquid has fluttered with time, distilled water is added. Since the electrolyte does not pump out, only water rolls out.

The density drops when the acid is converted into sulfate and settles on the plates. They reduce the working surface, so the battery ceases to hold the charge and quickly discharged.

How to raise the density in the battery for the winter period, so as not to spoil it, told my friend the battery

In order to restore the battery, you need to conduct a reverse process. This requires only charging.

Pulse charging (automatic) works very well. But it is worth remembering that for other batteries takes several days of charge to restore the density, which ideally should be 1.27 - 1.28. SM3.

If you have a normal charger, then to pull the battery you need to install a small charge current and charge at least 24 hours! And perhaps you will have to spend 48 hours.

So you understand, now we are talking about the workers in general batteries that you just need to serve.

If the battery does not hold at all charges, for example you charged it, and after a few hours of idle time, it is again discharged (the right sign of shortening cans or collapsed plates) then such ankb will not work normally so that you do not do.

If the plates were scattered from time to time, then no cleaning and topping electrolyte will help him.

How to raise the density in the battery for the winter period, so as not to spoil it, told my friend the battery

The sign of the sprinkled plates is a dirty electrolyte. These are sulfates and particles of plates.

Impurities that are in the electrolyte contribute to the AKB self-discharge.

So, here's a simple and understandable conclusion. If you do not have problems at the moment with the battery, but you wish to serve it before winter, you need to do the following:

As need to attach distilled water. Put for charging using a small current, not less than 12 hours.

After installing the battery on the car, the electrolyte density and load fork should be measured, to determine how the battery holds the load.

And be sure to check which charge gives your generator. Since if the charge is low or too high, it will quickly disable your batteries, especially when it's cold on the street.

If the battery does not take charge, try using another charger!

I just have ankb, whose density is 1.25 and a slightly muddy electrolyte.

With the onset of the cold, he began to work badly. Here on it, I will conduct experiments with cleaning plates of soda, with the addition of electrolyte and will show you in detail in the next article!

Put your thumbs up and relax on the canal!
