11.9 If you are using the FULL (480 minute charge) mode, the Charge Remaining timer counts
down to 0 minutes, or the battery becomes fully charged, the charge cycle will be complete.
The CHARGED (green) LED will light, the charger will beep four times and the charger will
go into Maintain Mode. If you are using the FAST (35 minute charge) mode, the Charge
Remaining timer will count down to 0 minutes, the CHARGED (green) LED will light and
the charger will beep four times, but the battery may not be fully charged. If left alone, the
charger will continue to charge the battery until it is fully charged then go into maintain mode.
11.10 Press the CHARGE ON/OFF button before disconnecting clips.
Aborted Charge
If charging can not be completed normally, charging will abort. When charging aborts, the
charger's output is shut off, and the display shows CHARGE ABORTED on the top line
and BAD BATTERY on the bottom line. It will also beep four times to let you know. NOTE:
In the case of a severely discharged battery, the charger will go into abort mode. If, after
the output turns off, the battery voltage drops to under .2 volts, the charger will reset to
the default settings and the display will show 8V FAST on the top line and CONNECT
BATTERY on the bottom line.
Completion of Charge
Charge completion is indicated by the display showing CHARGE COMPLETE on the top line
and TURN OFF CHARGER on the bottom line. It will also beep four times to let you know.
When the charger has stopped charging, it will switch to the Maintain Mode of operation.
Maintain Mode
When the battery is fully charged, the charger will start Maintain Mode. In Maintain Mode,
the charger keeps the battery fully charged by delivering a small current when necessary.
The voltage is maintained at a level determined by the charge mode selected.
NOTE: The maintain mode technology utilized in Schumacher chargers 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 highly recommended.
General Charging Notes
Fan: It is normal for the fan to be on all the time. Keep the area near the charger clear of
obstructions to allow the fan to operate efficiently.
Restart: If any button is pressed after charging has started, the charging process will stop.
Press the CHARGE ON/OFF button to restart the charge cycle.
