What causes a battery to overvoltage?
Major challenges to both the battery and the system it powers can be the result of deviations from this range, either too high (overvoltage) or too low (undervoltage). During charging or the system’s break down, the condition of overvoltage arises in which the battery accepts more energy than its capacity.
