The battery stores chemical energy that's released as electricity when connected to an electrical device, like the starter motor.Whenever the engine isn't running or the charging system cannot generate enough electricity to support all of the car's electrical demands, it supplies electricity to run headlights, turn signals, interior lights, the radio and other accessories. The entire vehicle ignition system is completely dependent on the battery's constant voltage supply.
