Today car-gourmet.ru decided to tell you about such an important parameter as electrolyte level in battery And to introduce you to him closer. Below we will talk about what should be the level of this substance, how to check and add it. We also give the possible reasons for splashing electrolyte from the battery. But first will get acquainted with the terminology.
Electrolite: basic concept
Electrolytes are liquid-shaped or solid substances, in which ions are present in a certain amount. Ions are able to move independently and carry out electricity. If we talk easier and understandable, electrolytes are salts that can conduct electricity Due to the fact that there are ions in their composition, which, in turn, are formed in the process of electrolytic dissociation.Electrolyte level
The electrolyte level is not constant and during operation it gradually falls, regardless of that expensive or cheap. The level of level decline depends on the relay controller. If it works faulty, the water quickly turns away, and if everything is normal, then this happens much slower. For example, if the relay is faulty, then with an increase in voltage at the battery terminals above 14.5 V electrolyte, it is capable of pumping in just a couple of days, which leads to a rapid wear of the battery and its complete replacement. It is possible to determine the increased voltage on the terminals, both in the heating itself of the AKB itself and on splashes from the boiling electrolyte. Also, with high voltage, air will be out of the filling holes, and abundantly.It is possible to determine the electrolyte level in the battery, unscrewing the plug holes and peeling into the inside. In the place of contact of the electrolyte with a skirt, which comes from the holes themselves down and is in every bank, Menisk must be visible.
In the process of charging the battery, the electrolyte level increases. This reaction is the result of temperature expansion. Also, the cause becomes small bubbles from air and hydrogen, accumulating near the plates. It is for this reason, after charging, to check the level of the electrolyte, the battery is allowed to completely cool to obtain accurate data.
Increased electrolyte level will result in its leakage through holes in traffic jams.
Checking the level of electrolyte
Checking the level of electrolyte requires a certain preparation. First, as already mentioned above, if the battery was just disconnected from charger, then he needs to stand for a while. Secondly, work should be carried out in whole rubber glove. Thirdly, there should be pure water nearby so that in the case of the electrolyte in the case of entering hands, you could quickly wash it.Now the verification process itself is directly.
Batteries in transparent enclosures are checked by their visual inspection. With side, such ankb should be two labels (min and max), showing the allowable minimum and maximum level of electrolyte. The level of level is when the electrolyte is located in the middle between two labels.
Most batteries have a not quite transparent case, but there are still marks on it. In this case, it is necessary to unscrew all the plugs for checking and see that the electrolyte is at a distance at least 1 cm above the surface of the plates, but it did not exceed the maximum mark.
That is, in both cases, the electrolyte level in the battery is visually carried out without the use of special means. However, in order to obtain accurate data, it is necessary to arm a glass tube at least 10 cm long.
This tube is inserted until it stops to the upper edge of the plates in the bay opening of the battery. As soon as it is inserted, her hole at the end needs to be closed with a finger. After that, the tube is getting and the line is measured the length of the electrolyte remaining in it. If the level is slightly more than 10 cm, it means everything is in order. With the indicators below, 10 cm electrolyte is worth adding.
Toping electrolyte
To work, you can use the finished electrolyte or prepare it yourself.For the preparation of the electrolyte, distilled water (1 liter) and sulfuric acid (0.36 liters) will be needed. Distilled water can be replaced by stunned water from the module or rain (settling should not be carried out in metal tanks). Water water to use is completely prohibited.
All ingredients pour into plastic containers and stirred everything carefully. After that, close the container with a dense lid and leave the substance for a day. After 20-24 hours, the electrolyte is ready for use.
To pour the electrolyte into the battery you need to unscrew the plug on the bay hole and put it on the fitting of the ventilation opening. Wear it upper. After that, just pour distilled water through the thread of the hole and tighten the cork back. Charge the battery.
Upon completion of the charging, the electrolyte density is measured in the battery. For these purposes, you will need a special device - an areaometer. But we would recommend to call in a specialized service, where you would tell exact indicators. After all, for each battery its permissible density rate. And the prepared electrolyte is fastened only in the case of low indicators.
Causes of splashing electrolyte
We complete this article description possible causes splashing electrolyte from battery.And so, the reasons may be as follows:
- Excess of the permissible level of electrolyte;
- Damage to the battery case;
- Voltage regulator fault;
- Sulfation of battery plates (full failure of the battery).
Auto-Gourmet.Ru sincerely hoped that from this article you learned all that you wanted to know about the level of electrolyte in the battery. Do not forget to check the battery in a timely manner and in the case of which you always hold ready.
The battery is definitely the most important detail of any car. So that there are no problems when starting the engine, the battery (AKB) must necessarily match the power of the car. The higher the power of the engine, the larger capacity Must stand acb. For example, on "Zhigulenok" it is desirable to put a battery with a capacity of 60 a / hour. These requirements are fully consistent with reliable domestic battles: Tymen Battery, "Acts", "AKOM" and others. Given the modern requirements for traveling and the day with the closest light, it will be a guarantee of a permanent battery working state. On the other hand, it is unacceptable to put heavy-duty batteries, since such ankb can lead to the failure of the elements of the car electrical equipment.
For the same reason, do not approach the "Seek" to the owners of powerful cars - high current On the start of the engine can play a cruel joke.
Follow the level of electrolyte
The electrolyte in the battery is a 36% aqueous solution of sulfuric acid. Its average density should be 1.28 g / cc. Lead plates in banks are all the time in a fully immersed state - the electrolyte level must rise above them by 10-15 mm. Make measurements with a glass tube, lowering it into the plug hole to the plates and climbing the top hole with a finger. The pillar's height in the tube must match the specified numbers.
On the battery with a transparent case, the electrolyte level is determined visually. It should be located between MIN and MAX marks.
As a result of operation, evaporation of the water component of the solution and the drop drop is possible. In this case, it is necessary to add distilled water into banks. The electrolyte is valued only in the case of a solution spill. At the same time, in no case is not allowed to fill directly into the banks of concentrated acid!
If you are exploiting unqualified batteryIn them, the procedure of the Treatment is not provided. but this type Akb requires more strict demands In operation.
Other Operation Rules Akb
To your battery serve for a long time and did not let down in the most critical situationsObserve the following basic rules on its operation:
- watch the serviceability of the relay generator and periodically measure the voltage issued by the generator;
- Keep the pole conclusions of the battery clean. It is desirable to cover them with consistency lubrication;
- Do not store the battery in the discharged state;
- Run the engine short-term (5-10 sec) turn on the starter with interruptions by 10-15 seconds.
Future motorists are taught not only how to drive a car, but also from what it consists. To your "Iron horse" worked as a clock, you need to have at least a minimum knowledge of the car maintenance and repair. Today we will talk about how to check the electrolyte in the battery.
What does the electrolyte level affect?
Autoinstructors believe that the battery does not require maintenanceBut only if it is used under standard conditions. This is the right opinion, but when long trips And when exposed to high temperatures, experts advise from time to time to control the level of electrolyte located in the battery. If, of course, you have a served battery.
First of all, we note that the electrolyte consists of acid and distilled water, that is, water can evaporate, for example, at high temperatures.
If the electrolyte level is very low, then due to the drying of the inner plates, it loses its power. And this later will lead to a dense cellular connection.
And, on the contrary, in the case of a too high level of electrolyte, excessive acid will damage (and quite strongly) the outer part of the battery. Other causes of problems due to improper level of electrolyte is:
- self-discharge, that is, with a long parking lot of the car or because of high consumption current;
- the voltage regulator breakdown, which is in the generator.
So the proper level of electrolyte is a guarantee of the normal functioning of the battery and the machine as a whole.
Battery electrolyte check procedure
Check the electrolyte in two ways. The first is at the maximum and minimum mark, that is, the fluid level can be seen with the naked eye, as the battery case with marks is usually transparent. If the level is between max Mark And min, then everything is in order.
If these marks are not, then there is a second way. First you need to prepare a glass tube, where the inner diameter does not exceed 5 mm.
Next, we unscrew the cover on the battery and omit the tube inside until it is stripped into the safety shield. The outer hole closes with a finger. Then pull the phone. The level of electrolyte in it is a measurable level.
The optimal value of the electrolyte in the battery
It is believed that the normal value of the electrolyte in the battery should be between 10 and 15 millimeters. If the obtained value is in this range, then your battery is in order and do nothing with it.
But if the value exceeds the allowable, that is, there is an extra liquid, it can be removed with a pear or a syringe. In the event of a lack of electrolyte, distilled water fills.
Remember that water from under the tap cannot be poured, otherwise the battery will simply discharge. The temperature of distilled water should be 15-25 degrees.
By the way, when working with an electrolyte, observe increased security measures. During the inspection of the battery, always wear rubber gloves so that the acid does not hit the skin of the hands because of which it is possible to get a burn. If the liquid still sheds into unprotected hands, then as soon as possible, rinse it with running water.

The main condition for the normal operation of the standard car battery is normal level electrolyte. Of course, this statement is true only to those batteries that use a liquid medium to operate charged plates. IN gel batteriesFor example, it is impossible to check the level of the electrolyte, because the medium itself is gel, and the battery case does not understand. But most motorists prefer precisely old options acid batteriesthat work in a liquid working environment. Today we will consider the situation when the level of electrolyte in the battery is reduced.
Today it is quite difficult to argue about certain problems of the battery, since the types of devices, their varieties and the complexity of the repair today are forced to think about the meaning of the service - for many it became easier to buy a new battery and forget about the problem. Manufacturers actively began to make non-maintained batteries, that is, such batteries, in the case of which it is extremely difficult to get. After reducing the level of electrolyte in such devices, they simply utilize and buy new ones.
Battery maintenance and addition of electrolyte into the system
Let's start with the fact that the battery that has already started to reduce the level of electrolyte, often has a serious problem. In such a battery, working plates could be sprinkled, or in the case of the device was formed to flow, which is even more dangerous. In such cases, the electrolyte evaporates or follows, collapses or converts. In a word, it becomes an order of magnitude less.
Because of such a decrease in the number of working fluid, plates occur, which should not touch each other. Also the top working element that holds the charge is not covered working fluidthat quickly destroys it. Therefore, it is impossible to reduce the level of electrolyte in the battery, and the loss can be filled in the following way:
- make sure your disposal is serviced by the battery, that is, you can reach the inside;
- unscrew all the upper tubes to assess the level of electrolyte in different banks batteries;
- carefully inspect the battery for the presence of leaks or cracks from which the liquid can be cooked;
- to add to the distilled water tanks to the level, which is determined by the manufacturer as optimal;
- leave traffic jams open and connect a charger to the battery to resume charge;
- periodically monitor the process of charging, estimating the state of the electrolyte and the visual properties of the inner part of the battery;
- if the electrolyte will boil or becomes muddy after turning on the charger, it is worth getting rid of such a battery and buy a new one.
The turbid liquid inside the battery says that your battery is no longer capable of maintaining a normal charge. The top layer of lead plates or other elements that are responsible for the work of the battery and holding the charge for a long time remaining collapsed. Such ankb can be touched at any time, and in winter it is not possible in winter.
Of course, most of the problems with car batteries is detected in winter timeWhen the battery is immersed in extreme conditions for itself. However, in the warm season, a sharp leakage of fluid or evaporation may occur due to a violation of the normal operation of the device. Often a sharp decrease in the level of fluid in the battery will mean the need to replace this element.
Recovery work Akb or buying a new battery?
In working with a car battery you need to be extremely careful, because the electrolyte in most modern batteries use hazardous sulfuric acid. By adding distilled water, you reduce the density of the electrolyte, which reduces the efficiency of the battery. But this is the only way to somehow extend the life of the device and postpone the purchase of a new battery.
Nevertheless, do not keep themselves with hopes that distilled water and distilled water will be able to fully revive normal work battery. Often to restore the battery completely fails at all. After a short time, the battery will again require interference. If the battery began to show a character, it is better to change it and not to substitute yourself for the danger of an unforeseen breakdown. The main factors for choosing a new battery are as follows:
- determination of the nominal capacity of the battery, which is recommended by the manufacturer (sometimes you can buy AKB by 10 a * h more recommended);
- selection of the desired starting current with a possible change from the factory characteristics only towards the increase;
- consideration in the store only those options for batteries that are ideal in shape and will be installed without any problems;
- choice by manufacturers, assessing the reliability of batteries on various ratings and reviews, the purchase of only official equipment of well-known brands;
- visual assessment of the battery in the store or in delivery, checking for the absence of various physical damage, the irregularities of the case;
- assessment of the battery life - Akb, stood in the store for two years, can already be considered used.
The battery life for the car is equal to 7-9 years to the maximum. But this period begins to be considered not from the moment of installing the battery on the car, but from the moment the element is released from the factory. Therefore, do not buy batteries on stocks and sides, because thus sellers most often try to get rid of illiquid products, which will soon cost a penny.
Also give up experiments with technical characteristics. Many motorists with the time of operation of the machine begins to seem to appear that they know their own transport. better producer. In fact, the best technical specifications Specified in the operating instructions Experiments with volume, starting current, size and other parameters are not completed for the machine well. We offer to watch videos with all battery tests and some tips for preparing the battery for winter operation:
Let's sum up
Recently, life car batteries Actively went to reduce. Therefore, in most cases, it is necessary to prefer to replace any other options for repair and restoring batteries. It leads to increased expenses For operation and significant waste for unforeseen breakdowns. When the battery fails in the middle of the route, the driver has to spend a lot of time, forces and means for delivering the car to the garage.
Therefore we recommend choosing only high-quality equipment with excellent characteristics. So you can guarantee yourself excellent operating opportunities, as well as get rid of constant problems with the battery. Buy Akb with a guarantee from the manufacturer and do not forget to regularly inspect this node for possible violations in the work. If you have something to add batteries from your own experience, be sure to share information in the comments.
Thanks rechargeable battery We have the ability to run a motor. Currently, there is a huge amount of acB of various brands, tanks and quality. But we will touch the topic of service, as it is this that is the main uninterrupted operation of the product. Nevertheless, not everyone knows how to check the level of electrolyte in the rechargeable battery. Although it is extremely simple to do it and now consider how it is.
Akb location under the hood of the car
Before proceeding directly to business, you need to find a battery under the hood. Different car brands suggest the accumulation of the battery in different places. In most cases, it is located on the left side of the engine, near air filter. There is also an installation option under the front left wing ( american cars). The same brands like "Mercedes", "BMW" or "Volvo" set the battery in special compartments in the trunk.
With any scenario, before checking the level of electrolyte in the battery, you need to find it. Next can be moved to the next step. 
Careful cleaning of AKB
Before checking, it is advisable to completely clean the battery from road dust, dirt, and corrosion. It is necessary that the battery does not get trash in the "banks". In addition, the pure body will suspend corrosion.
If the latter is available, then you need to remove it. For this, it is suitable as a special rust solvent sold in auto shops or a solution of soda with water.
Of course, the service is more convenient to perform, after having dismantling the battery, but this can not be done, it all depends on the situation. If the terminals are strongly zakisli and coated corrosion, they must be dipped in boiling water and clean carefully. Just before dressing back, you need to dry them. 
How to check the level of electrolyte in the battery?
There are several types of filling holes on the battery. There may be 2 rectangular or 6 round. The point does not change. Rectangular corks are fitted with a flat object and are dismantled, and round covers twisted with a wide flat screwdriver counterclockwise.
It is likely that you will see the inscription "maintenance-free" on the battery. In this case, the manufacturer recommends simply replace the faulty battery. If you saw the dirt under the plugs, then it must be removed. At the same time, make sure that nothing fell inside. If you hold such a procedure regularly, it will be possible to slow down the corrosion process inside the battery and save the plates in the normal state.
Check and maintenance
Before you need to increase if it is required, you must perform it. To do this, check the level of electrolyte in the wells. It should be the same everywhere. At the same time, I would like to draw your attention to the fact that the normal level of electrolyte in the battery must be observed for its efficient operation. IN summer time It can evaporate a little, so if necessary, then plot distillate. 
An essential difference in the electrolyte level in banks may indicate a crack in the building. It is better to replace such a battery, as at the most inopportune moment she can refuse. In addition, the electrolyte falling on the body can cause metal corrosion. In some cases, the crack can be searched, but this is a temporary solution.
What should be the level of electrolyte
We have already figured out a little, how to check the level. But it is not always possible to understand, you need to add or not. I would like to note that the level of electrolyte in the battery in winter is usually preserved in its usual position. Normal is the one that fully covers the plates. Also permiss and overflow at 0.5 cm. The drop drop requires an attachment of distilled water.
If everything is in order, then tighten the traffic jams and perform the next check after 3 months of operation. For a more accurate level check, you must use a flashlight and determine overflow (meniscus).
How to increase the electrolyte density in the battery
Before raising the density, it is necessary to adjust the level. To do this, alternately pour distilled water to the desired mark. If the battery is discharged, then we fill it up to the lower part of the neck and put it for charging. Since when heated, the electrolyte is expanding, it is possible to hit the case and partial leakage. 
The adjusting element is a correction element - an elevated density electrolyte. It must be addressed to the banks before obtaining the desired result. So how to increase the density of the electrolyte in the battery is simple enough, then there should be no problems with this procedure. After the attribute, check the level and density, if everything is in order, put the battery back to the car.
About battery stress measurements
This article presents the electrolyte density table, which can be used during adjustment. Before charging, it is desirable that the level is normal. We take a multimeter and connect to "-" and "+" batteries. It is necessary to achieve 12.6-12.9 volts. In this case, the AKB can be considered a fully charged and ready-to-use. Remember that riding on a discharged battery contributes to gradual destruction. This is especially true of calcium acb. Now you know a little about how the car battery is maintained with your own hands. The electrolyte level should always be followed, and if necessary, adjust. Sometimes the electrolyte density is too high. In this case, it is necessary to dilute it with distilled water. Having achieved the necessary value, the battery can be used.
Individual protection means
How to check the level of electrolyte in the battery, we figured out. It is worth saying a few words about what you will work with acid. Therefore, it is desirable to use rubber gloves, as well as special glasses. Acid into the eyes is very dangerous, so you have clean water at hand, which in the case of which you can use. 
Of course, B. emergency cases You can do without protection, but it should be extremely careful. In general, it is always necessary to keep the normal level of electrolyte in the battery, do not ride on the discharged battery and do not use the battery with a destroyed body. Regular service and check are the key to long and uninterrupted work Power element. There are also non-listed batteries, they are not clear from the name, absolutely not provided for foreign interference. This battery is completely sealed, and if it fails, then nothing but replacement will not help.
