What is the harm of battery heating?

Feb 14, 2012

The battery in the charging and discharging process, will release certain heat. But a lot of heats is very harmful to the battery. Heating will make electrolyte water evaporation and dried up at first, and then gradually reduce the charging efficiency, deform plate, increase resistance, make the mechanical components oxidation, burn out plates or clapboard, finally reducing battery capacity and shortening battery life.
