BATTERY CONNECTION INDICATOR
If the charger does not detect a
properly connected battery, the
CONNECTED (yellow/orange) LED will
not light. Charging will not begin if the
CONNECTED LED is not on. When
charging begins, the CHARGING (yellow/
orange) LED will be lit.
COMPLETION OF CHARGE
When the CHARGED (green) LED is
lit, the charger has completed charging
and switched to the Maintain Mode of
operation.
AUTOMATIC CHARGING MODE
When the SMALL BATTERY or LARGE
BATTERY size is selected, the charger is
set to perform an automatic charge. When
an Automatic Charge is performed, the
charger switches to the maintain mode

The times given are for batteries with a 50%
charge prior to recharging. Add more time for
severely discharged batteries.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging aborts,
the charger's output is shut off and the
CONNECTED (yellow/orange) LED will
flash. In that state, the charger ignores all
buttons. To reset after an aborted charge,
unplug the charger from the AC outlet, wait
a few moments and plug it back in.
DESULFATION MODE
If a 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.
Activation of the special desulfation mode
is indicated by the CHARGING (yellow/
orange) LED blinking. If successful, normal
charging will resume after the battery

is desulfated. The CHARGING (yellow/
orange) LED will then stop blinking and
light continuously. Desulfation could take
up to 10 hours. If desulfation fails, charging
will abort and the digital display will blink.
MAINTAIN MODE
(FLOAT-MODE MONITORING)
When the CHARGED (green) LED is lit,
the charger has started Maintain Mode. In
this mode, the charger keeps the battery
fully charged by delivering a small current,
as needed. If the battery voltage drops
below a preset level, the charger will go
back into Charge Mode until the battery
voltage returns to the full charge level,
at which point the charger will return to
Maintain Mode. The voltage is maintained
at a level determined by the selected
battery type.
NOTE: For 12V AGM and Gel cell
batteries, the CHARGED (green) LED may
light before Maintain Mode has begun.
MAINTAINING A BATTERY
(Small Battery Size setting)
This charger automatically charges
and maintains batteries, keeping them
at full charge.
NOTE: The maintain mode technology
allows you to safely charge and maintain
a healthy battery for extended periods
of time. However, problems with the
battery, electrical problems in the
vehicle, improper connections or other
unanticipated conditions could cause
excessive current draws. As such,
occasionally monitoring your battery and
the charging process is required.
GENERAL CHARGING NOTES
Fan Operation
The charger's cooling fan helps it operate
efficiently. It is normal for the fan to start
and stop when maintaining a fully charged
battery. The fan does not run in Tester
Mode. Keep the area near the charger
clear of obstructions, to allow the fan to
operate efficiently.
Restart
If the Charge Mode is changed after
charging has started (by pressing the
BATTERY TYPE or SIZE button), the
charging process will restart.
Voltage
The voltage displayed during charging is
the charging voltage and is usually higher
than the battery's resting voltage.
