Prepare to Charge
CAUTION: Avoid Contact! Battery acid is a
highly corrosive sulfuric acid!
1. To charge the battery outside of the vehicle, remove
the ground terminal rst. To prevent arcing, turn off all
accessories in the vehicle.
2. Charge the battery in a ventilated area.
3. Clean the battery terminals before charging. Use
baking soda and water to neutralize battery acid and
reduce airborne corrosion. Do not touch eyes, nose,
or mouth.
4. Add distilled water to each cell until battery acid
reaches level specied by the battery manufacturer.
Do not overll. Batteries without the removable cell
caps, such as valve regulated lead acid batteries
(VRLA), follow manufacturer’s recharging
instructions.
5. Study all battery manufacturer-specic precautions
while charging and recommended rates of charge.
6. Refer to the vehicle owner’s manual to determine
battery voltage.
7. Ensure tight charger clip connections.

Charger Location
1. Position the charger as far away from the battery as
the DC cables permit.
2. Never place the charger directly over the battery
being charged; gases from the battery can corrode
and damage the charger.
3. Do not set the battery on top of the charger.
4. Never allow battery acid to drip onto charger when
reading electrolyte-specic gravity or lling the
battery.
5. Do not operate the charger in closed-in area or
restrict ventilation.
DC Connection Precautions
1. Connect and disconnect DC output clips only after
setting any charger switches to "off" position (if
applicable) and removing AC cord from the electric
outlet. Never allow the clips to touch each other.
Clips may be energized and they may spark.
2. Attach clips to the battery and chassis, refer to the
Battery Installation section.

Charging Battery in Vehicle
CAUTION: To prevent bodily harm, avoid sparks
and battery explosions.
IMPORTANT: If the vehicle hood closes on the
cables, the charger components can be
damaged. Ensure that the hood does not touch
the metal part of the battery clips or cut
insulation of the cables.
1. Position AC and DC cables to reduce the risk of
damage caused by the hood, door, and moving or hot
engine parts.
2. Stay clear of the fan blades, belts, pulleys, and other
parts that can cause injury.
3. Check polarity of the battery posts. The positive
(POS, P, +) battery post usually has a larger diameter
than negative (NEG, N, -) post.
4. If the negative post is grounded to the chassis (as in
most vehicles), see step 5. If the positive post is
grounded to the chassis, see step 6.
5. For a negative-grounded vehicle, connect positive
(red) clamp from the battery charger to the positive
(POS, P, +) post on the battery. Connect the negative
(black) clamp to the vehicle chassis or engine block
away from the battery. Do not connect the clamp to
the carburetor, fuel lines, or sheet-metal body parts.
Connect to a heavy gauge metal part of the frame or
engine block.
6. For a positive-grounded vehicle, connect negative
(black) clamp from the battery charger to negative
(NEG, N, -) post on the battery. Connect positive
(red) clip to the vehicle chassis or engine block away
from the battery. Do not connect the clip to the
carburetor, fuel lines, or sheet-metal body parts.
Connect to a heavy gauge metal part of the frame or
engine block.
7. When disconnecting the charger, disconnect the AC
cord, remove the clamp from the vehicle chassis, and
then remove the clamp from the battery terminal.
8. When charging is complete, disconnect the charger
from AC power, remove the clamp from the vehicle
chassis, and then remove the clamp from the battery
terminal.
Charging Battery Outside Vehicle
CAUTION: To prevent bodily harm, avoid sparks
and battery explosions.
1. Place the battery in a well-ventilated area.
2. Check polarity of the battery posts. The positive
(POS, P, +) battery post usually has a larger diameter
than negative (NEG, N, -) post.
