BOOST MODE
To select the Boost mode, press the Rate Selection button until the yellow/orange Boost LED lights solid.
The Charging LED will light solid if battery is properly connected and the boosting process will start.
While in Boost mode, the display will show the voltage. If a bad battery is detected, the display will show
"bad/bat" and an error code.
NOTE: Boost mode will remain energized until the Rate Selection button is pressed.
CHARGE/MAINTAIN MODE
To select this mode, press the Rate Selection button until the yellow/orange 6<>2A Charge/Maintain LED
lights. The Charging LED will light solid if battery is properly connected and the charging process will
start. The display will show the charger voltage. To change the mode on the display, press the Display
button. When the battery is fully charged, the green Charged/Maintaining LED will light. If charging
cannot be completed, the display will show "bad/bat" and an error code. The battery may be bad;
have it checked.
NOTE: If the voltage of the battery is under 12.7V, the charger will automatically go into Boost mode,
to quickly add energy to the battery. To abort/skip the temporary Boost and force the charger into the
Charge/Maintain mode, press the Rate Selection button again (while still boosting).
AUTOMATIC CHARGING MODE
When an Automatic Charge is performed, the charger switches to the maintain mode automatically after
the battery is charged.
ABORTED CHARGE
If charging cannot be completed normally, charging will abort. When charging aborts, the charger's
output is shut off and the display will show "bad/bat" and an error code. Do not continue attempting to
charge this battery. Check the battery and replace, if necessary.
DESULFATION MODE
The display will show "SUL" when a sulfated battery is detected, and the charger will go into desulfation
mode. If the desulfation is not successful after 10 hours, the charger will go into abort mode. The display
will show "bad/bat/F02".
COMPLETION OF CHARGE
Charge completion is indicated by the green Charged/Maintaining LED. When lit, the charger has
switched to the maintain mode of operation.
MAINTAIN MODE (FLOAT MODE MONITORING)
When the green Charged/Maintaining LED is lit, the charger has started maintain mode. In this mode,
the charger keeps the battery fully charged by delivering a small current when necessary. If the charger
has to provide its maximum maintain current for a continuous 12 hour period, it will go into abort mode
(see Aborted Charge section). This is usually caused by a drain on the battery or the battery could be bad.
MAINTAINING A BATTERY
The unit charges and maintains both 6V and 12V batteries.
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.
