Charging your battery outside the vehicle:
1. Remove battery from vehicle, making sure to dis-
connect grounded terminal first with all power
turned off to the vehicle.
REMEMBER: A marine battery should be removed
and charged on shore unless special equipment
designed for marine use is available. Hydrogen
gas emissions can create an explosion if battery
is charged on board your boat.
2. Check the polarity of the battery posts as indicated
on the battery case: POSITIVE (POS,P,+) and
NEGATIVE (NEG,N,–).
NOTE: On top-post batteries, the positive battery
terminal usually has a larger diameter than the
negative one.
3. Connect the red (POSITIVE) charger clamp to the
POSITIVE post of the battery. Be sure to rock the
clip back and forth to make a solid connection.
4. Attach a 6-gauge (AWG) or a 4-gauge (SAE) insu-
lated battery cable of at least 24-inches in length to
the NEGATIVE battery post. This cable will provide a
safer connection because any arcing and sparking
will not occur directly over the battery. (The battery
cable is not provided with the charger, but may be
purchased at most automotive accessory outlets.)
5. Take the other end of the 6-gauge (AWG) or a
4-gauge (SAE) insulated 24-inch cable and, standing
as far away from the battery as possible, connect the
black (NEGATIVE) charger clamp to the free end of
the cable. Be sure to rock the clamp back and forth
to make a solid connection.
IMPORTANT: Wear safety glasses and face
away from battery while you are making the final
connection.
6. Set the VOLT/AMP SELECTOR switch and TIMER
to the OFF position. Next plug the power cord into a
grounded AC outlet.
7. Set the TIMER to the desired charge time, from 30-
135 minutes. If more than 135 minutes of charging
time is needed the hold position can be used. When
using the HOLD feature the battery being charged
must be monitored closely to avoid over charging.
8. Set the VOLT/AMP SELECTOR to the desired
charge position. (See “CHARGE RATE” chart on page
12 for correct settings.)
9. When battery is fully charged, the ammeter pointer
will be in the farthest left position and the voltmeter
pointer will be in the green area of the meter.
10. When the battery is fully charged, turn timer knob
to the OFF position, then unplug the charger power
cord. Stand away from battery and remove the
charger clamps from the NEGATIVE end of the cable
first, then from the POSITIVE post.
11. Clean and store the battery charger.
