What level of electrolyte should be in the battery? Recommendations

A modern car necessarily has a battery in its system. It is responsible for starting the work of the motor, as well as all the electricians of the machine. During maintenance, the battery should be cleaned and the charge level checked.

The measurement procedure can be made independently. . For this, first of all, it is necessary to find out what level of electrolyte should be in the accumulator . Experienced auto mechanics are ready to give a number of recommendations for car battery maintenance.

Device Features

, необходимо изучить подробнее его устройство. Before you find out what level of electrolyte should be in the battery , you need to study its device in more detail. There are two types of batteries. They are divided into maintenance-free and maintenance-free batteries. Recently, the second type of devices is more popular.

Serviced batteries have the ability to pour electrolyte inside when needed. However, this will require certain tools. Maintenance-free batteries are replaced with a new device after exhausting their life. When such a battery is unusable, the indicator will glow dimly green. In this case, you can not extend the battery life.

Electrolyte creates a certain environment, which accumulates electricity through a chemical reaction. This solution is concentrated sulfuric acid in distilled water. When these two substances interact with each other, a large amount of heat is released.

Electrolyte density

, необходимо сказать о его допустимой плотности. Considering what the electrolyte level should be , it is necessary to say about its permissible density. Sulfuric acid in its pure form is characterized by a rather high value of this index. Its density is equal to 1.8 g / cm³.

The electrolyte in the battery should not exceed 1.44 g / cm³. Density can vary from 1.07 to 1.3 g / cm³. The temperature of the mixture will be about + 15 ° C. The quality of sulfuric acid should be high. Otherwise, the battery may quickly become unusable.

A low level of electrolyte helps to dry the inner plates of the device. It will not be possible to restore the battery. Therefore, it is important to know how to refuel the battery.

Why does the level change?

может меняться в силу естественных причин. The level of electrolyte in the car battery can vary due to natural causes. It is considered normal if the amount of liquid in the battery's capacity is above its plates at the 11-15 mm boundary.

The electrolyte is estimated visually. Its decrease is due to the evaporation of water from the solution. This increases the concentration of sulfuric acid. The density of the solution will be higher than the original value.

If in the course of the operation of the machine all the unfavorable factors are combined simultaneously, the life of the battery can be exhausted in almost 1 month. If the driver has noticed even a small glitch in the on-board electronics system, he should inspect the battery and determine the level of internal contents.

Change in operating level

, нужно знать особенности его изменения при эксплуатации устройства. Before you check the electrolyte level in the battery , you need to know the features of its change when operating the device. Over time, it constantly falls, regardless of whether an expensive battery was purchased or cheap. The speed of this process depends on the relay-controller. If this item of equipment is defective, the liquid quickly boils away. And the timing of this process can be very short.

As experts say, when the voltage at the terminals is increased to 14.5 V, if the relay-regulator is faulty, the electrolyte boils away in just a couple of days. The device will most likely require a full replacement. It can not be restored.

If the battery becomes very hot, splashes from the boiling electrolyte appear, it is necessary to take urgent measures. At high voltage, air will escape from the holes to fill the liquid.

Determination of electrolyte level

. There are two ways to check the fluid level in the car battery . The first is suitable for the owners of batteries, on the case of which there are labels. Two parallel lines indicate the minimum and maximum amount of solution inside the container. The state of the electrolyte is visually assessed and a decision is taken on the further operation of the battery.

For devices in which there are no such labels, there is another way to estimate the amount of solution. To do this, it is necessary to use a glass tube (diameter 3-5 mm). After opening any plug of the device, it is inserted into the safety shield until it stops.

The hole that remains on the surface is covered with a finger. Next, the tube is removed from the battery and evaluated. The liquid remaining in it corresponds to the amount of electrolyte inside the test can.

The column of substance should be not less than 11-15 mm. This procedure must be performed for all cans. If in some containers the level is insufficient, it is necessary to pour the solution inside. When the level is higher than the specified value, the syringe or excess syringe must be eliminated.

Visual method

. There is another approach, how to check the electrolyte level in the battery . It is less precise, but in the absence of improvised means, too, will do. To do this, unscrew the plugs of the holes for filling the liquid. This must be done in good light.

Looking inside the can, you should evaluate how the electrolyte touches the skirt from the holes down. In each of them, a meniscus should be visible. This is the surface of the solution, which has a semicircular shape. A meniscus is formed between closely located walls of the vessel.

Some models of batteries have a special indicator. It is necessary to knock on it lightly. In this case, the color will be more clearly visible. Green shade is the norm. White color indicates the need to charge the device, and red - on the lack of water in the tank.

Recommendations of experts

There are some rules that experts are advised to adhere to. They must be remembered by checking the electrolyte level in the battery. сводятся к пониманию принципа работы устройства, а также выполнению рекомендаций техники безопасности. The basic rules are reduced to understanding the principle of the device, as well as the implementation of safety recommendations.

If the battery has just been removed from recharging, the electrolyte level will be high. This is due to the temperature expansion. Also, around the plates, hydrogen and air bubbles accumulate during the charging process. Therefore, experts say that the battery should be completely cooled down. Otherwise, it will be inaccurate.

All work is carried out in new rubber gloves. Just in case, it is necessary to put a sufficient amount of clean water nearby. If electrolyte gets on your hands, it should be rinsed immediately. Water is required for these purposes. Also it is necessary to protect the eyes with special glasses. The implementation of these simple recommendations will maximize the safety of metering.

Preparation of the solution

, можно предпринять меры по восстановлению требуемого значения раствора. After determining what level of electrolyte should be in the battery , you can take measures to restore the required value of the solution. If you want to top up it in a container, you need to prepare the appropriate material.

The solution can be purchased or prepared independently. To create the correct electrolyte, it is necessary to prepare 1 liter of distilled water (sold at the pharmacy). It will also require sulfuric acid in the amount of 0.36 liters. Tap water is not allowed for this purpose.

All components are poured into a plastic container. All you need to mix well. After that, the solution is closed with a dense lid and left for a day. Then you can use the prepared product.

Battery recovery

To fill the prepared solution inside, it is necessary to unscrew the plug and put it on the vent hole. The plug must be firmly seated on the corresponding hole. Then the product is poured in. The plug is twisted and charged.

Some drivers may wonder how to restore the battery. произведения этого процесса сводятся к зарядке при низком токе. The ways of producing this process are reduced to charging at low current. The procedure takes a long time, after which the density may increase slightly. Sulfuric acid can be poured in only when the plates are in working order.

, а также рекомендации экспертов, можно восстановить эксплуатационные свойства обслуживаемого устройства. Having considered what level of electrolyte should be in the battery , as well as expert recommendations, it is possible to restore the operational properties of the serviced device.
