General Description - Battery

The battery is an electrochemical device for converting chemical energy into electrical energy. The battery is also capable of storing energy and receiving a charge. The battery provides four basic functions.
1. Supplies electrical energy for accessories when the engine is not running.
2. Supplies energy to the cranking motor and ignition system as the engine is started.
3. Intermittently supplies energy to vehicle electrical devices when the electrical demands exceed the output of the generator.
4. The battery acts as a voltage stabilizer in the electrical system.
