How Does Lead-Acid Batteries Work?
During charging, the lead-acid battery undergoes a reverse chemical reaction that converts the lead sulfate on the electrodes back into lead and lead dioxide, and the sulfuric acid is replenished. This process is known as "recharging" and it restores the battery''s capacity to store electrical energy.
