CHARGE/MAINTAIN MODE
To select this mode, press the Rate
Selection button until the yellow/orange
6<>2A Charging/Maintaining LED lights.
The ON 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 pulse. 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 pulsing, 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 SC1307 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.
