6. If the vehicle has one battery, connect the
negative (-) battery cable to the negative (-) battery
terminal (1).
If the vehicle has dual batteries, connect both
negative battery cables to both negative (-) battery
terminals (4).

batteries rated at 850 cold-cranking amps each are used
in this vehicle. (Refer to the appropriate Owners/
Operators Manual for general information.)
a. Battery Description
The battery supplies power to the starter and ignition
system to crank the engine, and it provides extra power
when the electrical load requirements of the vehicle
exceed the supply from the charging system in the event
of an alternator or charging-system failure. The battery
also acts as a voltage stabilizer in the electrical system,
smoothing out or reducing temporarily high voltage.
With the correct battery cables properly attached and with
the battery properly mounted, the battery does not
require periodic maintenance.
When starting the engine, allow the starter to crank for a
maximum of 15 seconds only, then wait a minimum of two
minutes to help avoid burning out the starter. Also, DO
NOT let the engine idle excessively, as low engine rpm
can also lead to battery discharge.
Keep the battery from freezing by maintaining a full
charge. A completely discharged battery will freeze at
18° F (8° C).
Due to the maintenance-free design, water NEVER has
to be added to the battery, so there are no filler caps.
Each battery is sealed, except for small vent holes in the
cover. The vent holes allow gas and pressure produced
in the battery during charging to escape. The special
chemical composition inside the battery reduces gassing
to a very small amount at normal charging voltages. The
special chemistry also greatly reduces the possibility of
overcharge damage.
The vents require that the battery be kept in an upright
position, to help prevent electrolyte leakage. Tipping the
battery beyond a 45° angle in any direction can allow a
small amount of electrolyte to leak out of the vent hole.
DO NOT exceed this 45° angle when carrying or installing
a battery.
The battery has top-post terminals. Keep the terminals
clean, and securely tighten clean cable clamps onto the
posts. Grease or special spray sealers may be applied
over the connections.
WARNING:
All lead-acid batteries
generate hydrogen gas, which is highly
flammable. If ignited by a spark or flame, the
gas may explode violently, causing spraying of
acid, fragmentation of the battery, and cause
possible severe personal injuries. Wear safety
glasses when working near batteries. In case
of contact with acid, flush area immediately
with water.
