When the battery begins to "boil" the level of electrolyte falls and its density becomes greater. If you "run" this moment and do not fix it on time, then the AKB can over time to lose its container. So that he "does not boil", it is necessary to add the required amount of distilled water into it. Before you start doing this, the best solution will be consulted with a specialist or at least ask the more experienced car owner, how to add water into the battery. Before that, it is necessary to clean the surface of the battery. This procedure is necessary for several reasons. First. The surface is most likely heavily contaminated with sulfuric acid, which splashed during a boiling, and contact with it is dangerous for a person and his clothes.
Second. Dirt can get inside the battery and spoil it even more. Third. It is simply nicer to do work clean. In order to clean the surface, you need to gently wipe it with a damp cloth. It is best to smoke the tissue with a solution of food soda. Available on the top lid of deepening, especially around the plugs, it is easiest to be cleaned with a match or cotton wand. In the battery you can pour only distilled water. Moreover, only in banks in which the level of electrolyte is lower than the minimum. The level of translucent batteries in special notes - risks on the sides of the case are determined. Inside the filling holes, you can see the tides that indicate the upper and lower levels. If there are no labels, then you can navigate the level of about 10-15 mm above the top of the plates.
Top water in the battery is recommended using a conventional rubber pear, a large syringe or using an aerometer (more precisely, its external flask) to measure the electrolyte density. After taking water, the electrolyte density is not restored not immediately, since there are small gaps between the plates between the plates and mix the liquids therefore rather slowly (sometimes the density is restored only after a few weeks). For this reason, after adding water, the battery should stand for at least a few hours. Only in this case the density indicators are more or less close to real, and it can be measured.
In order to determine the most accurately to determine the density, it is necessary to measure it several times at equal intervals. If the difference between measurements before and after is not very high, it means that the battery is ready to operate again after a small recharging. The most common error of car enthusiasts with small experience is a top of the dismissal water. If we fill in the battery conventional water from the tap, which contains a lot of different impurities and salts, the density of the chemical composition of the electrolyte is broken. Because of this, then the battery begins to lose the charge faster, sulfation and destruction of the plates occurs, and the battery capacity is reduced.
Another frequent mistakes is the topping of water in the cold. This should not be done for obvious reasons - the upper electrolyte layer in this case simply freezes, not having time to mix with the bottom. The result may be the destruction of the hull of the battery itself, as well as the output of it. If in the winter immediately before the trip somewhere, the need to add water is found, then it is better to do it before departure, otherwise you have to mess around on the road, and then it may be possible to buy a new battery. To make the density of the electrolyte faster, it is possible to drive it up to the norm after the top of the top (up to 40-50 minutes) on the car running at idle. You can also add water into the battery when the engine is installed.
Another of the most common motorist entry errors is forgetfulness or simple negligence. Many do not bother clean the surface of the battery from pollution. What can happen from this, described in one of the first items of this article. This is how the usual human laziness can lead to the fact that the battery even new will simply stop how their functions should be performed or will stop working and will go to the recycling market.
There are cases when the AKB requires a water tank to restore the electrolyte level. In no case cannot add it before reloading. It is also a typical error of inexperienced or lazy drivers. Simply during recharging the volume of electrolyte increases, and the excess fluid can simply fire through the covers, damaging cables, clamps, stands and floors. You can not add water before 2-3 hours before the end of recharge. Errors often make those who have never read the instruction manual for the battery and those who are inattentively, "between lines" read tips that are given on the forums on how to add distilled water into the battery.
The low level of electrolyte automotive battery says either about leakage, or on the evaporation of the fluid to which the boiler leads. The latter is accompanied by an increase in density, which causes harm to the instrument up to the destruction of the plates and the complete loss of performance. To avoid this, it suffices to reduce the concentration of the acid of the working mixture by adding water into the battery. But it must be absolutely clean, so it is recommended to use distillates.
Purified fluid is obtained by two-time evaporation and condensate collection. The result is getting rid of outsided salts, minerals and other substances. That is, there is a clean H 2 O at the exit. In the desired proportion, sulfuric acid and water create the necessary electrical conductivity of the working mixture.
Condensate after evaporation during the operation of the automotive battery does not leave the sediment. Therefore, it can be constantly tossed into the battery without consequences. That is, deposits will not appear on the electrodes. The presence of impurities threatens to adversely affect the battery:
- The occurrence of precipitate on the plates, because of which they are constantly destroyed, the resistance increases and the container decreases.
- Unpredictable electrical conductivity change.
- Acceleration of the self-discharge, due to an increase in the density of the working mixture.
Attention! Distilled water is sold at gas stations and stores. But there are fakes there. Therefore, even by purchasing the necessary product, you can pour ordinary water into the battery with all the ensuing consequences.
So that this does not happen, it is enough to check for the availability of information about the manufacturer on the label. The most reliable to measure the electrical resistance to the tester. Without impurities, it will strive for infinity, otherwise the instrument will show a specific figure.
What will happen if pour boiled water?
In the absence of a distillate, it seems the only solution to add a fluid to acid with a different way, for example, boiled water. Requirements for conventional water from under the tap implies cleaning. This is true, but its processing always leaves a large amount of various substances. This quality water can be used in food, but not to use to dilute the electrolyte. This is the result of the standards that the presence of salts of rigidity, metals are allowed, and some elements must be mandatory.
If you pour boiled water into the battery, the situation will not improve much. At 100 ° C, rigidity decreases, forming a precipitate. However, it does not fall to zero. In addition, there is a lot of steam, without taking a single foreign substance. The volume decreases, and impurities remain. The action from heat treatment will be, but the following is:
- disinfection from which it absolutely does not depend on whether this liquid can be added to the battery or not;
- reducing the share of water and a total volume and, as a result, an increase in the concentration of impurities;
- loss of precipitate from the salts of temporary rigidity, with a constant nothing happens, that is, the effect is meager;
- as a result, the concentration of minerals remains almost at the same level, and this worsens the properties of the electrolyte.
Important! Pour into the battery conventional drinking quality water or boiled categorically impossible. The composition is first saturated with numerous impurities. The second does not differ in the content of foreign substances. As a consequence of their use, all the disadvantage of pollution will affect the battery.
What can be poured instead of distilled water into the battery?
What is the quality of water to add to the battery, if you do not get to the nearest store to buy the necessary fluid? To begin with, try still to purchase the required, because distillates are also sold in pharmacies. Car owner will need only a roomy container, it is desirable not iron. If this method is unavailable, it remains to add to the acid electrolyte close in composition analogues.
These options are rather sparing rather than a full replacement. Even in the last two points there is one evaporation, whereas the fluid recommended for electrolyte passes the procedure twice. Is it possible to add one of them a working mixture depends on the required quantity and confidence in their quality. For example, the purity of precipitation from rain or snow strongly affects the dustiness and contamination of air. It is more reliable to add such water into the battery after it dents. During the day, impurities will fall, the upper layers will remain either without them, or with a minimum amount.
Preparation of distilled water for battery with your own hands
There are several ways to independently prepare distilled water at home. Two most faithful. First, without tangible harm, you can add the collected pairs from a boiling teapot into the working mixture of the battery or pan. The main thing at the same time is not to forget about high temperatures. Capacity or barrier for condensate you need to keep a towel so as not to burn.
The second method will suit the owners of the device for obtaining alcohol, or rather moonshine. If it is pouring and overtaken by ordinary water, the required condensate will be at the output. One disadvantage: the process takes a lot of time, since the device is designed for another density and volatility of substances. This design is really done with your own hands, and simply and simply:
In everyday life, boiled water has the best drinking quality due to the disinfective action of high temperature. By purity, it is practically no different from the tap taken. The distillate is manufactured at home. And the replacement of its counterparts will still damage certain harm. Although the latter is less compared to the one that will occur if in the battery pour ordinary water even after thermal processing. If you find yourself in a similar situation, please share your experience solving a problem in the comments.
The car is not alive, but capricious. Everyone knows that bad gasoline or diesel fuel, antifreeze and oil will not fill in it. But after all, he needs the right - distilled! We understand how to use it with maximum benefit for your iron horse.
Many are perplexed, looking at the bottle with transparent liquid, marked "GOST 6709-72": they say, is it just water, how can it cost so expensive? It is impossible to drink it even!
Only here distilled water is not simple water, but purified by distillation through the distiller. It contains at least impurities and has low specific electrical appliances. That is why it is indispensable when servicing the car, and it is not necessary to save on it.
We offer four ways to use distilled water:
1. Top the distilled water into batteries
Pulling the water into the battery when swinging electrolyte - an ordinary, but very responsible procedure. Only distilled water should be used as the diluent, otherwise the battery life will be reduced by more than 2-3 times.
The fluid that is filled with a battery is a solution of sulfuric acid with additives, expensive and complex components like self-discharge inhibitors, barium salts and strontium. These electrolyte additives retain parts in pristine purity and ensure stable battery operation.
Conventional water contains calcium, magnesium, iron, zinc salts and other impurities - almost half of the Mendeleev table! If you add it to the battery, a fragile chemical equilibrium will break. The plates of the electrodes will cover the flare, the battery will begin to "fool" - badly charged and not to keep the current. Because of this, problems will begin with the launch.
2. Dilute antifreeze distilled water when the cooling fluid is dropped
Surely you noticed that over time, the cooling fluid level in the cooling system drops, although there are no currents in it. It happens because water evaporates from antifreeze. During the year, up to 1 liter of coolant can disappear from the cooling system. The difference between the minimum and maximum level of antifreeze level is usually only 0.5 liters!
The lower the level of coolant, the greater the risk that the air will fall into the upper part of the radiator, the stove and cooling channels. At a critical moment, the engine will start overheating, and as a result - the risk of breakage will increase by an order. Therefore, if there are no leaks in the cooling system, and the fluid level fell, topping distilled water to restore the concentration of antifreeze. Find distilled water is much easier than a suitable cooling fluid. In addition, in this case you do not need to think about the compatibility of antifreeze, and it will be cheaper as a result.
By the way, the automaster use distilled water in order to rinse the cooling system when replacing antifreeze. This simple procedure prevents the formation of scale and other harmful deposits. And the purity in the cooling system is the key to the fact that there will be no problems in the engine.

3. Use distilled water instead of a glass washer
In the manual leading automakers, black on white it is written that only distilled water can be poured into the washer tank. Otherwise, there will be a lime flare, precipitate and even Tina in the wash system. Over time, these contaminants will scratch the nozzles of the sprayers and break their work.
Distilled water as a washer fluid can be used both in the solo version and dilute the concentrate washers (both summer and winter), which are much better coped with mud or insect traces.
4. Use distilled water at home
White lime bloom on black fabric after you logged out a completely clean thing - the usual problem of those who pour ordinary water from under the tap into the iron. Filtering and boiling with impurities in tap water do not cope. Pour distilled water into irons, and then no unpleasant surprises are terrible. It is also possible to fill it into the system of individual heating in a private house - it is also sensitive to harmful sediments.
And still distilled water recommend using electrocamine manufacturers in which the flame effect is formed with the help of light and water vapor. Like a car system, such devices are very demanding to the quality of the fluid and will work much longer, if you pour off distilled water in them.
The rechargeable car battery is on average in operation from 3 to 5 years, some Akb models are able to work up to seven, and even up to 10 years. But that the energy drive could serve for a long time, it should be regularly maintained, if necessary, fasten the water into the battery. With a low level of solution, lead plates in banks are rapidly destroyed, as a result of the sulfate, the battery fails. The service consists in the content of the battery clean, maintain the density and the required volume of electrolyte, and how much water to be poured, what a density should be and some other moments we will consider in this article.
The car rechargeable battery ensures the operation of energy consumers with a non-working engine, and also allows you to make an uninterrupted launch of the motor in different climatic conditions. Charging the battery gets from the generator, but if electrical equipment is faulty, the battery may lose charge and do not start the machine. We will not deeply immerse yourself in the theory, but let's try to explain the device and the work of this node with simple words. So, the battery for a passenger car:
- has six cans with lead plates, filled with electrolyte (sulfuric acid solution);
- each of the plates has electrodes with positive and negative charges;
- charging, the plates accumulate energy and give it to consumers (including the starter when starting the engine).
Sulfur solution in banks for the normal functioning of the AKB should contain a strictly defined proportion of acid and water, which is called density, and various battery problems occur when this balance is violated. The density would be a constant value, but when the plate accumulator is discharged, lead sulfate is covered with sulfuric acid hydrogen, entering into the reaction with oxygen, the solution becomes too "liquid", and the density drops.
It is necessary to add to the battery only water, and it is strictly forbidden to add electrolyte. The fact is that when charging the seed battery, the density increases to the desired level, the lost capacity returns, and if this does not occur, the battery is needed no longer, but recovery (if the battery has not yet failed). The electrolyte is poured only in the following cases:
- the very first refueling of the dried accumulated battery is performed;
- it is precisely established that the electrolyte of the seal from cans.
In the non-servant batteries, the topping is not required during the entire period of their operation, the banks of this type of batteries are sealed, and evaporation does not occur.
With the question, pour water or electrolyte, we have already figured out, now it is necessary to find out what fluid added by quality should be. Water is the usual (raw), boiled and distilled, and although all fluids externally and to taste are not much different, but they have different chemical composition. If you pour ordinary water, current from the crane, when joined the reaction with sulfuric acid, it can give an unpredictable result, as a result of a full charge of the battery will not happen. The thing is that this moisture contains many different salts, microparticles of metals, other impurities, and significantly affects the chemical process. Of course, in our time various filters are used, providing efficient cleaning, but they do not fully give a 100% result. Another option is boiled water, bacteria die from severe heating, but salts and other microparticles remain.
The distillate is the only composition of the liquid that is allowed for mixing with an electrolyte, it is released from dissolved and undisguised particles, does not conduct an electric current. Distilled water can be obtained in several ways:
The distilled liquid does not have taste and odor, and even the minimum number of different impurities is different, rainwater, but it is not recommended to add them to the electrolyte.
At the very beginning of the article, we have already noted that the low level of electrolyte in the banks of the battery can lead to the destruction of lead plates, so the electrodes cannot be dry, they are completely poured with a solution. But the water level should be determined, 10-25 mm above the upper edge of the plates (depends on the model of the AKB and the recommendations of the manufacturer's plant), any deviations from the norm in any direction lead to undesirable, and even sometimes to the deposits:
- if the electrolyte in the battery is flooded by little, the battery falls quickly, it is often completely out of order, even an explosion of AKB is possible under load;
- with too much level, the desired density is not achieved (1.27 g / cm³ is considered to be the standard), the liquid from the cans begins to go out, oxides appear on the housing and terminals.
But overflowing water is not so terrible as nothing, although he also does not bode anything good, for example, at low temperatures, it may not have enough density to start the engine starter. 
How to pour water:
With too much level (for the most "neck") density falls, and it is not possible to raise it even by charging. Therefore, in this case, it is allowed a little more than the norm to stretch a pear solution from the can and add not water, and the electrolyte. Such actions should be trusted to professional batteryers, you can not cope with the task and ruin the AKB.
Currently, the automobile industry is mainly produced by low-service batteries, they require a minimum of care, however, prevention should be carried out regularly. To serve the battery, you need:
- remove the battery with the car:
- attribute it to the warm room;
- clean the body from dirt and salt sediments (turning over the case can not);
- clean the terminals from the falling paper by sandpaper, if they are oxidized, wipe dry with clean rags;
- give to stand for 10-12 hours (you can and day, it is especially important to give the battery "to move" in winter).
Then check the level of electrolyte in banks, if necessary to add distilled water, put the battery for charging. Without a charger, it is not necessary to do here, as well as without a carometer, and it would be nice to have a multimeter and a loading plug. After the battery stand out, check the multimeter voltage without load, it must be in the range of 12.4-12.7 volts. When connected to the loader terminals, the voltage should not fall below 9.6 V, the load load lasts about 5 seconds.
After taking water to the desired level, the area is checking the density, in those banks, where it has accounted for more, respectively, there will be a smaller density. Then we put the traffic jams in places without spinning them, connect to the terminals the charger if the battery is in a fairly good condition, automatic mode is suitable for charging.
The most efficiently battery is charged at room temperature + 20ºC, after charging, it is necessary to give abbus, but it is already enough to 5-7 hours. Then repeat all the inspections again, the most optimal values \u200b\u200bare:
- stress without load - 12.7 volts (up to 13.0 V);
- under load - from 9.6 to 10.4 V;
- density - 1.27-1.28 g / cm³.
For the northern regions, the electrolyte density can be installed more (to a value of 1.31), 1.26 g / cm³ is often sufficient for the southern regions. Depending on the type of AKB, it is recommended to prevent the battery one or twice a year, minority batteries require maintenance more often, about once every 3 months.
Video: Water or electrolyte, what to add to the battery?Lead car batteries accumulate energy until a chemical reaction is underway between the electrolyte and conductive plates. When changing the density of the electrolyte, this process is broken. It doesn't matter for what reason the electrolyte has spoiled, the battery does not work. Replacing electrolyte, adjustment of the density or purchase of a new battery. In case the electrolyte has acquired a black color, there is a suspension of coal and scale - the battery will have to be changed.
The electrolyte is a mixture of sulfuric acid with water in a certain proportion. The concentration of the solution will be recognized by density measured by the area. The main indicator, even hundredths affect the ability of the electrolyte to work on the accumulation of energy.
Signs of unfit electrolyte:
The replacement of electrolyte in the battery will be effective when the cavities of the cans are examined, washed, the sulphate sediment is removed. If the plates are destroyed, the active substance matched - the battery is not maintained.
At home, the complete replacement of the electrolyte in the car battery occurs in the sequence:
- Prepare enameled or glassware to drain electrolyte, personal protective equipment, work space, better, outdoors.
- The battery is removed from the car, remove the plugs or drill holes in the non-serving battery, drain the liquid into the prepared container, using a pear or a syringe.
- The battery is washed with distilled water repeatedly until the precipitate is removed. Perhaps you will have to remove lead sulfate if there is a precipitate on the plates. It is necessary to make sure that the active smelting is not crumbled, the coal grille is.
- Slowly, with interruptions to pour the electrolyte of the desired density into each bank above the plates by 5-7 mm. Wait 2-3 hours to exit bubbles, measure the density of the electrolyte, bring to normal
- Charging the battery after the electrolyte is replaced to carry a small current of 0.1 A, not allowing boiling. After a set of half a capacity, charging is cyclically.
- Make sealing cans.
How much time to charge the battery? Charge the battery after replacing the electrolyte is needed carefully, as after deep discharge. The electrolyte replacement operation in the automotive battery is considered complete if it fully takes a current for a long time. Charging is carried out carefully, boiling in banks is unacceptable.
We offer to watch the video for the correct replacement of the electrolyte in the automotive battery.
Why can not top up electrolyte in battery
Did you measure the level of battery banks, is it below the norm? This means that part of the water evaporated. If this is served by the battery, you need to measure the level in each bank and add the electrolyte to the weather. In the abbrevatory battery, the bay mirror is visible.
The level has fallen, it means there is little water in solution and high density. The added electrolyte will increase the level, but the density of the solution will remain high. It is a detrimental for the battery plates, the battery life is reduced. Therefore, electrolyte should be adjusted to a level, topping distilled water.
Watch the video about electrolyte replacement rules.
In what cases to top up the electrolyte in the battery?
The electrolyte in the battery is attached when the container is reduced. At the same time, the measurement of the contents of each bank show the decrease in density. It is possible that sulfate occurred in the battery, the associated acid residue in PBSO4 is not involved in the reaction.
If the electrolyte extracted from the cans transparent, light, it can be used again, adding a correction solution, a density of 1.4 g / cm3. After removing the precipitate on the plates, the battery is filled with the previous electrolyte, but it is low concentration. Is it possible to bring the solution to the desired density, topping the electrolyte? What is the composition to take, and how much should I add to the battery of the corrective solution?
According to the technology, it is necessary to replace the portion of the weak composition strong. It is possible to add and withdraw the electrolyte from cans from cans, using a pear and a measuring cylinder. How to change the solutions in which proportion is seen from the table.
In this case, only the electrolyte for adjustment should be used. After the replacement operation, recharging is carried out for half an hour so that the fluids are mixed. Two hours after turning off the memory, the density is checked if necessary, the adjustment is repeated.
We offer to read the video, how to add electrolyte into the battery.
What to top up in battery, water or electrolyte
Under the operating conditions, the maintenance-free batteries do not require the control of the density and level of electrolyte. Served ACB have special traffic jams - access to each bank. They regularly check the quality indicator and level of electrolyte. Battery energy reserve is determined by the most weak element. Therefore, it is necessary to maintain the electrolyte density in all banks equal.
Density in the bank may decrease if sulfate began. Then the electrolyte adding does not help. The strong resistance of the slated plates does not miss the charge, the added acid will increase the deposit. In this case, the charge will restore sulfatization. That is why it is impossible to fill the electrolyte in the battery with the sulfate.
Does water to the battery? If the level of electrolyte in banks is low, it indicates intensive boiling battery during operation. It evaporates mainly hydrogen. From bare plates can turn an active melting, sulfatorium will occur, corrosion. Therefore, it is necessary to pour distilled water, but after that the battery needs to be charged for a complete cycle.
During the recovery period, the lead crystals are partially destroyed, the dense mortar is diluted, the electrolyte activity is restored. Tighten the electrolyte or water into the battery in the holes covered with corks, a small jet through the funnel. Charging starts not immediately to come out the air, the compositions mixed.
The density control should be made after half an hour after turning off the memory. With density deviations, perform adjustment.
When to add to the electrolyte, and when water
The question is how to add, if little electrolyte in the banks of the battery requires special lighting. Such fluids like electrolyte or distilled water, you need to fill in the battery correctly. The housing and funnel must be pure, poured fluid transparent, without suspension. You can add the electrolyte with water using a medical syringe without a needle if the adjustment is required to be insignificant.
When can I add water to the battery electrolyte? If in one or more banks the electrolyte level in the battery is low. This is due to the boiling of cans in an elevated temperature or deep discharge. The addition of distilled water is replenished with volume losses, the density of the electrolyte is reduced, the battery will be prevented.
Do I need to charge the battery after adding water, or replacing the electrolyte? Any internal balance change requires alignment and stabilization. After changing the concentration of the fluid, it is necessary to carry out a full charging cycle, make sure that the battery does not lose the container, stable voltage on the terminals, provides a starting current.
Is it possible to add the electrolyte into the battery if it is accidentally spilled out? How did it happen? Perhaps turned over the device. This is one of the few cases when the eliminated electrolyte is replaced exactly the same and even the temperature is customized. But still it will be necessary to recharge and check the density.
Watch the video how to correctly add the electrolyte into the battery. Water or electrolyte, what to top up?
How to add the electrolyte in the non-servant battery
Everything is much more complicated if it took to add water into the electrolyte of the car's non-servant battery. Through the translucent walls can be seen how much electrolyte in banks. But how to penetrate the housing of the non-servant battery?
There are models, penetrate inside in which you can cut off with a baccake upper cover. But such actions are needed if you need to remove scale and rinse the sludge at the bottom. In order to add liquid to the desired level drill the hole in the housing. Later it is sealed with epoxy glue.
The fully maintenanceable battery requires careful circulation, it is afraid of deep discharges and an unstable work onboard battery. He declared 5-7 years old only in ideal conditions.
How to disassemble a non-liable battery to add electrolyte
In modern battery, such as Varta, you can see 6 plates under the decorative sticker, tightly releated into the housing. If you hide a tilt circle, you can detect the rubber plug below it. Then the ability to select the electrolyte sample will appear, check the density, adjust the composition. If there is no plug - in each bank, the hole is fine with a thin selection, and the water starts from the syringe, drops.
But if it is found that in banks on the plates, whitic stripes are sulfate. To clean the cavities, remove the precipitate at the bottom, you will need to open the cover with the saw.
Look at the video, how to add the electrolyte into a non-servant battery.
Add electrolyte in gel battery
Pull the water in the battery banks simply. It is necessary to remove the sticker on the body, remove the valves caps and roll 1.2 ml of water into each jar. Water should absorb in the jelly-shaped mass. Need time. After half an hour, if the water is above the surface of the battery plates - remove it with a filter or syringe.
