Operation CHARM: Car repair manuals for everyone.

General Description






The maintenance-free battery is standard equipment in all vehicles. Batteries with side or top terminals are available.

These vehicles may be equipped with more than one battery, depending on the powertrain used and optional equipment. The battery is completely sealed except for two small vent holes in the sides. These vent holes allow a small amount of gas produced in the battery to escape.

The battery has three functions in the electrical system:
- The battery provides a source of energy for cranking the engine.
- The battery acts as a voltage stabilizer for the electrical system.
- The battery can, for a limited time, provide energy when the electrical load used exceeds the output of the generator.






The battery specification label contains information pertinent to servicing the battery. This information includes test ratings and original equipment. The label also includes numbers for recommended replacement parts.
