What voltage does each cell in a lead-acid battery produce?

Each cell in a lead-acid battery produces 2 volts. This is due to the electrochemical reactions that occur within the battery's cells. A typical lead-acid battery consists of multiple cells connected in series, with each cell generating 2 volts when fully charged. Therefore, a standard 12-volt lead-acid battery is made up of six cells.

The chemistry involves the reaction between lead dioxide and sponge lead, which generates electrical energy as sulfuric acid facilitates these reactions. Understanding this basic principle is essential for the maintenance and operation of lead-acid batteries in various applications, including aviation, automotive, and industrial uses.
