Categories: My Car. The battery, starting and charging systems are interrelated by a continual cycle of converting chemical energy to mechanical energy and then back again. The starter motor uses mechanical energy to crank the engine and once the engine is running, it's really a merry-go-round sort of relationship. The rotation of the engine drives the alternator, forcing electrical energy (current) into a battery, where it's stored as chemical energy.
