CHARGE RATE
The charger will automatically adjust the
charging current, based on battery size,
in order to charge the battery completely,
efficiently and safely.
BATTERY CHARGING TIMES
Times are based on a 50% discharged
battery and may change, depending on age
and condition of battery.
AUTOMATIC CHARGING MODE
When the 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. Have it checked or replaced.
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
CHARGED (green) LED. When lit,
the charger has switched to the maintain
mode of operation.
MAINTAIN MODE
(FLOAT-MODE MONITORING)
When the CHARGED
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. Make sure there are no loads on

the battery. If there are, remove them. If
there are none, have the battery checked
or replaced.
MAINTAINING A BATTERY
The SC1304 maintains both 6 and 12 volt
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.
USING THE BATTERY VOLTAGE
TESTER
1. With the charger unplugged from the
AC outlet, connect the charger to the
battery following the instructions given
in previous sections.
2. Plug the charger AC power cord into
the AC outlet.
3. If necessary, press the BATTERY
TYPE button until the correct type is
indicated.
4. Read the voltage on the digital display.
Keep in mind that this reading is only a
battery voltage reading; a false surface
charge may mislead you. Compare the
reading to the chart below.
6 V Battery 12 V Battery
Voltage Voltage
Reading Reading
6.4 or more 12.8 or more
6.1 to 6.3 12.2 to 12.7
Less than 6.1 Less than 12.2
POWER-UP IDLE TIME LIMIT
If no button is pressed within 10 minutes
after the battery charger is first powered
up, the charger will automatically switch
from tester to charger if a battery is
connected. In that case, the charger will
be set to charge at the 3A rate and gel
cell battery type.
TESTING AFTER CHARGING
After the unit has been changed from
tester to charger (by selecting a charge
rate), it remains a charger. To change the
battery charger back to a tester, press the
CHARGING RATE button until all charge
rate LEDs are off.
