NOTE: This charger is equipped with an auto-start feature. It will not supply
current to the battery clips until a battery is properly connected. Unlike traditional
chargers, the clips will not spark if touched together.
USING THE QUICK-CONNECT CABLE CONNECTORS
Connect either of the two output cable assemblies to the charger in seconds.
Make sure to place the charger on a dry, non-flammable surface like metal or
concrete.
NOTE: Never connect the clamp and ring terminal connectors together for use in
other applications, such as external battery or other power source charging, or to
extend the output cable length, as reverse polarity and/or overcharge conditions
will occur.
BATTERY CLIPS: Connect the battery clip cable assembly to the charger. Follow
the safety instructions in sections 6 or 7 to connect the output clips to the battery.
RING TERMINALS: The ring connectors permanently attach the battery
providing easy access to quickly charge your battery. This application is
appropriate for motorcycles, lawn tractors, ATV’s and snowmobiles. To
permanently attach it to a battery, loosen and remove each nut from the bolts at
the battery terminals. Connect the red positive ring connector ring to the positive
(POS, P, +) battery terminal. Connect the black negative ring connector ring to
the negative (NEG, N, -) battery terminal. Replace and tighten the nuts to secure
it. Take care to keep both wires and plug away from metal and the engine hood.
Connect the ring connector cable assembly to the charger.
Aborted Charge
If charging can not be completed normally, charging will abort. When charging
aborts, the charger’s output is shut off, and the CHARGING
(yellow) LED
will blink. To reset after an aborted charge, either disconnect the battery or
unplug the charger.
Desulfation Mode
If the battery is left discharged for an extended period of time, it could become
sulfated and not accept a normal charge. If the charger detects a sulfated battery,
the charger will switch to a special mode of operation designed for such batteries.
Completion of Charge
Charge completion is indicated by the CHARGED (green) LED. When
lit, the charger has stopped charging and switched to the Maintain Mode of
operation.
