CAUTION:
Batteries produce explosive gases, contain corrosive acid, and supply levels of electrical current high enough to cause burns. Therefore, to reduce the risk of personal injury when working near a battery:
- Always shield your eyes and avoid leaning over the battery whenever possible.
- Do not expose the battery to open flames or sparks.
- Do not allow the battery electrolyte to contact the eyes or the skin. Flush immediately and thoroughly any contacted areas with water and get medical help.
- Follow each step of the jump starting procedure in order.
- Treat both the booster and the discharged batteries carefully when using the jumper cables.
The maintenance-free battery is the standard original equipment battery. There are no vent plugs in the cover. The maintenance-free battery is completely sealed except for two small vent holes in the side. These vent holes release the small amount of gas that is produced in the battery.
The battery has three functions as a major source of energy:
- Engine cranking
- Voltage stabilization
- An alternate source of energy with a generator overload.
The battery specification label contains the following:
- The test ratings
- The original equipment catalog number
- The recommended replacement model number
