The cells initially had low capacity.
A lead-acid battery consists of lead plates, lead oxide, and a sulfuric acid and water solution called electrolyte. The plates are placed in the electrolyte, and when a chemical reaction is initiated, a current flows from the lead oxide to the lead plates. This creates an electrical charge that can be used to power various devices.
