Replace the battery with a new one, because when this happens to the battery, it means that a vulcanization reaction has occurred inside the battery, which greatly increases the internal resistance and decreases the capacity. Moreover, it is difficult or even impossible to repair a severely vulcanized battery. Even if it is repaired, the performance will be greatly reduced, which will have an impact on the subsequent use of the vehicle.

Can minor vulcanization be repaired?

For batteries with a low degree of vulcanization, it can actually be repaired. The performance of the battery after repair is about 80% of the original performance. Commonly used repair methods are as follows:

1. Chemical repair method:Pour out the original electrolyte of the battery, add pure water and a mixture of lead sulfate, potassium sulfate, and tartaric acid, try to charge and discharge several times, and then add dilute sulfuric acid to adjust the concentration of the electrolyte.

2. Cycle charging method:Usually charging the battery is usually a little more than ampere current. At this time, you can change it to 4 amps for charging, and then discharge some power from the battery. Repeat this process several times to solve the problem of slight vulcanization of the battery. But pay attention to one point, the temperature of the battery should not be too high during charging, otherwise it will be damaged.

How to avoid battery loss in normal times?

In fact, it is not difficult to avoid battery power loss, as long as our car owners pay more attention to the use of batteries, as follows:

1. After parking and turning off the engine, you should pay attention not to use the electrical appliances such as dome lights on the car for too long, otherwise it will easily cause the battery to lose power;

2. When the car owner is free, he can drive outside for a while, let the generator charge the battery for a while, and at the same time relax his mood;

3. When the car is not going to be used for a long time, unplug the negative pole of the battery, so that the electric appliances on the car will not consume the battery power, and the battery will not lose power. But do not unplug the negative pole for too long, otherwise some data of the trip computer will disappear.
