However, in some cases, such as high temperatures or long periods of operation, the electrolyte may gradually evaporate, resulting in a drop in the electrolyte level, which prevents effective heat dissipation and increases the internal temperature of the battery

Heat Effects during the Operation of Lead-Acid Batteries

Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as "thermal runaway." This

How Lead-Acid Batteries Work

Keep the battery away from open flames, sparks, or heat sources. Lead-acid batteries can produce explosive gases during charging or discharging, so do not smoke or use electrical appliances nearby.
