Charging your battery outside the vehicle:
1. Remove the battery from vehicle, making sure to
disconnect grounded terminal first with all power
turned off to the vehicle.
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 at least a 6-gauge (AWG) or a 4-gauge
(SAE) insulated 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 automo-
tive 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) lead to the free end of the
cable. Be sure to rock the clamp to make a solid
connection. IMPORTANT: Wear safety glasses
and face away from the battery while making the
final connection.
6. Set your charger's right-hand 3-position selector
switch to the OFF position. Then plug the
charger's power cord into a grounded AC wall
outlet.
7. Select the desired charge rate. (See "Setting the
Controls" on page 7.)
8. The charger will not stop when the battery is fully
charged. For this reason it is important to check
charging progress frequently. Overcharging can
damage a battery, you must monitor and unplug
charger when battery is fully charged.
9. When the battery is fully charged, the AMMETER
needle will fall to about half the charge rate
selected. For specific positions, see the "Amme-
ter" section of "Settings the Controls" on page 7.
10. When the battery is fully charged, unplug the
charger power cord before attempting to discon-
nect charger clamps.
11. Facing away from the battery, remove the charger
leads. Remove the NEGATIVE clamp first, then
from the POSITIVE battery post or terminal.
12. Clean and store the battery charger in a dry
location.
