What Is A Car Battery?

A car battery is a lead-acid battery that supplies electric energy to an automobile. Its main purpose is to start the engine by supplying the initial current to the starter motor. Once the engine is running, the battery provides power to the lights and ignition system. The battery also provides power to accessories such as the stereo and air conditioning when the engine is turned off.

Car batteries are made up of six cells connected in series. Each cell produces about 2 volts for a total of 12 volts. The cells are filled with sulfuric acid and water solution. Lead plates are used as electrodes, and they react with sulfuric acid to produce lead sulfate and water. As the battery discharges, the lead sulfate becomes lead dioxide. When the battery is recharged, the reverse reaction occurs and lead dioxide and water are converted back into lead sulfate.
