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:
| • | Alternate source of energy with generator overload. |
The battery specification label contains information about the following:
| • | The original equipment catalog number |
| • | The recommended replacement model number |
Battery Ratings
A battery has two ratings:
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 time (in minutes) necessary to discharge a completely
charged battery to a terminal voltage of 10.5 volts under the following
conditions:
| • | A constant rate of 25 amperes. |
| • | A constant temperature of 27° C (80° F). |
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.
