The battery contains two lead plates, one coated in lead dioxide and the other in pure lead, submerged in a solution of sulfuric acid. When the battery is discharged, the sulfuric acid reacts with the lead to create lead sulfate and hydrogen ions. This releases electrons, which flow through an external circuit to power a device.
Lead–acid battery (LAB) is the oldest type of battery in consumer use.
