FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED OUTSIDE OF VEHI-
CLE. A SPARK NEAR THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO
REDUCE THE RISK OF A SPARK NEAR BATTERY:
1. Check polarity of battery posts for top-mounted battery connectors, the POSITIVE posts
(marked POS, P, +) usually has a larger diameter than the NEGATIVE battery post (marked
NEG, N, –). For side-mounted battery connections, the POSITIVE terminal is RED, the
NEGATIVE terminal is black.
2. Attach a 24-inch (minimum length) 6 AWG insulated battery cable to the NEGATIVE bat-
tery post (marked NEG, N, –).
3. Connect the POSITIVE (RED) battery clamp to the POSITIVE battery connector (marked
POS, P, + or RED).
4. Stand as far back from the battery as possible, and do not face battery when making
final connection.
5. Carefully connect the NEGATIVE (BLACK) charger clamp to the free end of the battery
cable connected to the negative terminal.
6. Set the charge rate to appropriate setting according to battery size.
7. When disconnecting charger, always do so in reverse sequence of connecting proce-
dure and break first connection while as far away from battery as practical.
8. A marine (boat) battery must be removed and charged on shore. To charge it on board
requires equipment specially designed for marine use.
