1. Work with this Battery Charger and gasoline or diesel powered engines ONLY in a well-ventilated area.

systems only. Use on 6 or 24 Volt systems may damage the battery, automotive circuitry or this
charger.
3. Rotate the Function Switch to the OFF position.
4. If charging a battery while in a vehicle, leave the hood open and do not leave the charger unattended.
Separate the charger and battery as much as possible.

unscrew the cell caps and fill each cell to the full
indicator with distilled water. Replace caps.
6. If charging a battery mounted in a vehicle, first remove
the vehicle’s red cable from the battery; otherwise
damage may occur to the vehicle’s electrical system. If
in doubt, refer to the vehicle’s service manual.

positive (red) Cable Clamp to the positive terminal of
the battery. Connect the negative (black) Cable Clamp
to the negative terminal of the battery. Note: This
Battery Charger is equipped with a non-polarity
operation function, which will allow it to function

A deep cycle charge at 12 Amps may take as little as 10-15 minutes. A trickle charge at 2 Amps may
take several hours. Periodically check on the progress of the trickle charge. Do not leave this product
unattended for several hours without periodically checking on its operation.
This Battery Charger operates in Automatic Mode, and will discontinue charging when the battery is
fully charged. When the battery is fully charged the Battery Charger will automatically shut down, and
the green LED will remain lit.
