How Does Lead-Acid Batteries Work?
When a lead-acid battery is in use, it undergoes a discharge process. During this process, the lead-acid battery releases electrical energy as its chemical energy is converted. The discharge process can be described as follows: The sulfuric acid in the electrolyte combines with the lead dioxide on the positive plate to form lead sulfate and water.
