The battery is like a "lifeline" that provides supplies for the car. However, the high temperature will evaporate the water in the battery, causing the plate to be exposed and accelerate the oxidation, and the white oxide will appear at the pole head, causing the voltage of the battery to be unstable.

First determine the volatilization or leakage

The life of the battery is one year, and some can reach 3 to 4 years. Once there are problems such as insufficient power or inability to charge, most owners choose to add distilled water, but the results may not be ideal. Some people have doubts: "The composition of the battery is not distilled water or deionized water?" Adding distilled water is a good idea."

That's only half true. The battery does contain distilled water and deionized water, but it also includes concentrated sulfuric acid with a density of 1.84, which is synthesized with distilled water and deionized water, with a density between 1.25 and 1.40, while the density of distilled water is 1.00, and direct addition will reduce the density of the electrolyte.

What about direct electrolyte replenishment? The result is the same, but the density is increased, but the vulcanization phenomenon will occur on the plate, and ultimately affect the service life. In view of this, when dealing with, the owner should first find out the reason, in the end is the high temperature evaporated the water in the battery, or the electrolyte leakage, and then treat the specific situation.

Correct handling method

If the high temperature evaporates the water in the battery, resulting in a lower liquid level, then distilled water must be added, because the electrolyte density is very high at this time. If it is an electrolyte leak, then directly replace the same density of electrolyte.

Note: When adding, do not be higher than the limit range of the electrolyte level, which is easy to overflow the electrolyte, resulting in poor contact or damage to the pole, and will cause excessive internal pressure of the battery, or even make it explode.

Maintenance-free batteries can also run dry

The appearance of maintenance-free batteries has greatly reduced the consumption of electrolyte. However, many owners believe that maintenance-free batteries do not need to do any maintenance. If the owner holds this idea, then it is naive.

Maintenance-free battery is only a form of battery, with shock resistance, high temperature resistance, small size, small self-discharge characteristics, the service life can reach twice the ordinary battery.

There are two kinds of maintenance-free batteries: one is a one-time addition of electrolyte, which does not require maintenance in use; The other is that the battery has been added to the electrolyte and sealed when it leaves the factory, unless there are professional tools and technology, others can not repair and replenish the liquid by themselves.

Although it is maintenance-free, it does not mean that the owner can use it indefinitely. If it is roasted at a high temperature of 40 ° C, its internal electrolyte will also be evaporated, so it is also necessary to check the charging situation and quality status through the small hole on the battery cover every day, generally green indicates qualified; Black indicates loss of power, starting the vehicle is not smooth; White indicates that the battery is damaged and needs to be replaced.

warn

Maintenance-free batteries do not see the liquid level line like ordinary batteries, so it is difficult to grasp the amount of addition. If there is maintenance-free battery defect during the warranty period, it will be replaced directly; If it's out of warranty, it's scrapped.
