Notes:
• Battery voltage selection cannot be changed during charging; the battery must be disconnected before selecting the charger voltage.
• The battery is fully charged when the green LED is illuminated. You can stop charging the battery at this point or keep it connected in floating status.
• To end a charging session, disconnect the AC power cord from the source, then disconnect the charger's clamps from the battery terminals.
Mounting (Optional)
The 4-in-1 Charger can be mounted to a horizontal surface. To
mount, install four fasteners (not included) through the charger's
mounting slots into a rigid surface. Secure the fasteners as far
back in the mounting slots as possible, otherwise the fasteners
may loosen and cause the charger to slide back and forth.
Note: The user is responsible for determining if the hardware and mounting
surface are suitable to support the charger.

Description/Solution
Current is charging slowly
Battery drawing maximum charge current
Battery reaches set voltage limit; adjusts to draw
less charge current
Battery near 100% capacity; approaching
floating status
Battery charge full
Battery charge full and floating current < 0.5 A
Check fuse and replace if broken
Check that battery voltage selected on charger
matches battery's voltage
Defective thermal sensor; follow the Service
instructions on the next page
Unit cooling down; will automatically restart upon
reaching average internal operating temperature
