The maintenance-free battery is standard in all vehicles. The battery is completely sealed except for two small vent holes in the sides. These vent holes allow the small amount of gas produced in the battery to escape.

The battery specification label contains information pertinent to the servicing of the battery. This information includes test ratings and both OE (Original Equipment) and recommended replacement part numbers. Refer to Battery Usage table.
