What is the situation when a car battery heats up and leaks water during charging?

[LeKai]

The situation when a car battery heats up and leaks water during charging: 1. The leakage of water during battery charging is related to the principle and structure of the battery. The reason why the battery can store electricity is that it converts electrical energy into chemical energy; 2. The battery adopts a lean liquid design. During the charging process, gas evolution will occur inside the battery, and the intense activity of the active substances on the two plates will generate heat, causing the electrolyte level to rise, resulting in the phenomenon of water leakage during battery charging. When charging the battery, the current should be selected as one-tenth of the battery capacity, or one-twentieth of the battery capacity. When water leakage is found during battery charging, the battery liquid level should be checked. When the liquid level is lower than the standard line, pure water or distilled water should be added in time, and the added water should not exceed the standard line.
