Constant voltage charging maintains a fixed voltage level, allowing the current to taper off as the battery approaches full charge. Lead acid batteries work through electrochemical reactions. During discharge, lead dioxide and sponge lead react with sulfuric acid to produce lead sulfate and water. During charging, this reaction is reversed.
