Quizplus · Accepted Answer

The chemical reactions in a disposable battery are exothermic, which means they release energy. The reactions in a rechargeable battery during the discharging process are also exothermic. However, during the recharging process, energy is required to reverse the chemical reactions, making them endothermic. Therefore, a recharging rechargeable battery is driven by endothermic reactions.
