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 and the
CONNECTED LED is lit. 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. Periodically check the ring connectors to ensure
they are properly connected.
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 LED will flash. 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 LED. When lit, the charger
has stopped charging and switched to the Maintain Mode of operation.
