Battery heat builds up quickly, dissipates slowly, and rises swiftly in the early stages of discharge, when the temperature is close to that of the surrounding air. Once the battery has been depleted for some time, the heat generation and dissipation capabilities are about equal, and the battery’s temperature rise becomes gradual.
