4. Load Test
1. Connect a voltmeter and a battery load tester
across the battery terminals.
2.
Apply 300 ampere load for 15 seconds to remove
surface charge from the battery. Remove load.
3. Wait 15 seconds to let battery recover. Then apply
specified load from specifications (See Main Data
and Specifications in this section).
Read voltage after 15 seconds, then remove load.
a. VOLTAGE DOES NOT DROP BELOW THE
MINIMUM LISTED IN THE TABLE –The
battery is good and should be returned to
service.
b. VOLTAGE IS LESS THAN MINIMUM LISTED –
Replace battery.

The battery temperature must be estimated by feel
and by the temperature the battery has been
exposed to for the preceding few hours.
Battery Charging
Observe the following safety precautions when charging
the battery:
1. Never attempt to charge the battery when the fluid
level is below the lower level line on the side of the
battery. In this case, the battery must be replaced.
2. Pay close attention to the battery during charging
procedure.
Battery charging should be discontinued or the rate
of charge reduced if the battery feels hot to the
touch.
Battery charging should be discontinued or the rate
of charge reduced if the battery begins to gas o
r
spew electrolyte from the vent holes.
3. In order to more easily view the hydrometer blue do
t
or ring, it may be necessary to jiggle or tilt the
battery.
4. Battery temperature can have a great effect on
battery charging capacity.
5. The sealed battery used on this vehicle may be
either quick charged or slow charged in the same
manner as other batteries.
Whichever method you decide to use, be sure tha
t
you completely charge the battery. Never partially
charge the battery.
Jump Starting
Jump Starting with an Auxiliary (Booster)
Battery
CAUTION: Never push or tow the vehicle in an
attempt to start it. Serious damage to the emission
system as well as other vehicle parts will result.
Treat both the discharged battery and the booste
r
battery with great care when using jumper cables.
Carefully follow the jump starting procedure, being
careful at all times to avoid sparking.
WARNING: FAILURE TO CAREFULLY FOLLOW
THE JUMP STARTING PROCEDURE COULD
RESULT IN THE FOLLOWING:
1. Serous personal injury, particularly to you
r
eyes.
2. Property damage from a battery explosion,
battery acid, or an electrical fire.
3. Damage to the electronic components of one o
r
both vehicles particularly.
Never expose the battery to an open flame or electrical
spark. Gas generated by the battery may catch fire o
r
explode.
Remove any rings, watches, or other jewelry before
working around the battery. Protect your eyes by
wearing an approved set of goggles.
Never allow battery fluid to come in contact with you
r
eyes or skin.
Never allow battery fluid to come in contact with fabrics
or painted surfaces.
Battery fluid is a highly corrosive acid.
Should battery fluid come in contact with your eyes,
skin, fabric, or a painted surface, immediately and
thoroughly rinse the affected area with clean tap water.
Never allow metal tools or jumper cables to come in
contact with the positive battery terminal, or any othe
r
metal surface of the vehicle. This will protect against a
short circuit.
Always keep batteries out of reach of young children.
