CAUTION: A MARINE (BOAT) BATTERY MUST BE
REMOVED AND CHARGED ON SHORE. TO CHARGE
IT ON BOARD REQUIRES EQUIPMENT SPECIALLY
DESIGNED FOR MARINE USE.
CAUTION: A SPARK NEAR BATTERY MAY CAUSE
BATTERY EXPLOSION. TO REDUCE RISK OF A
SPARK NEAR BATTERY:
1. Check polarity of battery posts. POSITIVE (POS, P,
+) battery post usually has a larger diameter than
NEGATIVE (NEG, N, –) post.
2. Attach at least a 24” long, #6 gauge (AWG) insulated
battery cable to NEGATIVE (Neg, N, –) battery post.
3. Connect POSITIVE (RED) charger clip to POSITIVE
(POS, P, +) post of battery.
4. Position yourself and the free end of the cable
(installed in step #2) as FAR away from the battery
as possible. FACING AWAY FROM THE BATTERY,
connect the NEGATIVE (Black) charger clip to the free
end of the cable.
5. When charging is complete, turn charging sequence
off by depressing the “CHARGE” button. Then
disconnect charger, always in reverse sequence of
connecting procedure and break first connection while
as far away from battery as practical.

CAUTION: A MARINE (BOAT) BATTERY MUST BE REMOVED AND CHARGED ON SHORE. TO CHARGE IT ON
BOARD REQUIRES EQUIPMENT SPECIALLY DESIGNED FOR MARINE USE.
CAUTION: A SPARK NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A SPARK NEAR
BATTERY:
1. Position AC and DC cords to reduce risk of damage by hood, door, or moving engine part.
2. Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
3. Check polarity of battery posts. POSITIVE
(POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N, –) post.
4. Determine which post of battery is grounded (connected) to the chassis. If the negative post is grounded to the
chassis (as in most vehicles), see Figure 1 and instruction 5a. If the positive post is grounded to the chassis, see
instruction 5b.
5. a) For NEGATIVE GROUNDED vehicle, connect POSITIVE (Red) clip from the battery charger to the POSITIVE
(POS, P, +) ungrounded post of the battery.
b) For POSITIVE GROUNDED vehicle, connect the NEGATIVE (Black) clip from the
battery charger to the NEGATIVE (NEG, N, –) ungrounded post of the battery. (This
arrangement is usually found in pre-1970 foreign vehicles or pre-1970 farm tractors.
This is a rare occurrence.)
6. Connect the remaining battery charger clip to the vehicle chassis or engine block, as far
away from the battery as possible. Do not connect the clip to carburetor, fuel lines, or
sheet metal body parts. Connect to a heavy gauge metal part of the frame or engine
block.
7. When disconnecting charger, turn charging sequence OFF by depressing the
“CHARGE” button, disconnect AC cord, remove clip from vehicle chassis, and then
remove clip from battery terminal.
8. Refer to the Operating Instructions for information on setting selector switches.
