Purpose of the Automotive Battery: 

The battery is the primary EMF source in the automobile. In addition the battery performs the following functions:

  • Provides voltage and current for the starter motor.
  • Provides voltage and current for the ignition during cranking.
  • Supplies all electrical power when the charging system is not operating.
  • Supplies the extra power necessary when the vehicle's electrical load exceeds the supply from the charging system.
  • Acts as a voltage stabilizer in the electrical system. The battery evens out voltage spikes and prevents them from damaging other components in the electrical system.
  • Provides power to KL30, KL15 and KLR.

The battery does not store electrical energy. It stores chemical energy that is converted to electrical energy as it discharges.
