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 standard. There are no vent plugs in the cover.
The battery is completely sealed except for 2 small vent holes in the side. These
vent holes allow the small amount of gas that is produced in the battery to escape.
The battery has 3 functions as a major source of energy:
• | Alternate source of energy with generator overload |
The battery specification label, example below, contains information about the
following:
• | The original equipment catalog number |
• | The recommended replacement model number |
Battery Ratings
A battery has 2 ratings:
• | Cold cranking amperage |
When a battery is replaced use a battery with similar ratings. Refer to the
battery specification label on the original battery or refer to
Battery Usage
.
Reserve Capacity
Reserve capacity is the amount of time in minutes it takes a fully charged battery,
being discharged at a constant rate of 25 amperes and a constant temperature of 27°C
(80°F) to reach a terminal voltage of 10.5 volts. Refer to
Battery Usage
for the reserve capacity rating of the original
equipment battery.
Cold Cranking Amperage
The cold cranking amperage is an indication of the ability of the battery to
crank the engine at cold temperatures. The cold cranking amperage rating is the minimum
amperage the battery must maintain for 30 seconds at -18°C (0°F) while
maintaining at least 7.2 volts. Refer to
Battery Usage
for the cold cranking amperage rating for this vehicle.
Auxiliary Battery
Auxiliary batteries are an available option on vehicles where many accessories
can be utilized such as TVs, radios, lights, computers, etc. The charging of these
batteries is explained in charging system description and operation. Also, the auxiliary
battery is only for accessory use and not part of the starting system.
