11. OPERATING INSTRUCTIONS
WARNING: A spark near the battery may
cause an explosion.
IMPORTANT: Do not start the vehicle with
the charger connected to the AC outlet, or
it could result in damage to the charger.
CHARGING A BATTERY
IN THE VEHICLE
1. Turn off all the vehicle’s accessories.
2.
Keep the hood open.
3. Clean the battery terminals.
4. Place the charger on a dry, non-
flammable surface.
5. Lay the AC/DC cables away from any
fan blades, belts, pulleys and other
moving parts.
6.
Connect the battery, following the
precautions listed in sections 6 and 7.
7. Connect the charger to an electrical
outlet.
8. When charging is complete,
disconnect the charger from the AC
power, remove the clamps from the
vehicle’s chassis, and then remove
the clamp from the battery terminal.
CHARGING A BATTERY
OUTSIDE OF THE VEHICLE
1. Place battery in a well-ventilated area.
2. Clean the battery terminals.
3. Connect the battery, following the
precautions listed in sections 6 and 7.
4. Connect the charger to the electrical
outlet.
5. When charging is complete,
disconnect the charger from the AC
power, disconnect the negative clamp,
and finally the positive clamp.
6. A marine (boat) battery must be
removed and charged on shore.
NOTE: This charger is equipped with
an auto-start feature. Current will not be
supplied to the battery clamps until a
battery is properly connected. The clamps
will not spark if touched together.
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 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
(yellow/orange) LED will flash. Do not
continue attempting to charge this battery.
Check the battery and replace,
if necessary.
DESULFATION MODE
Desulfation could take 8 to 10 hours. If
desulfation fails, charging will abort and
the (yellow/orange) LED will flash.
COMPLETION OF CHARGE
Charge completion is indicated by the
Charged/Maintaining (green) LED.
When lit, the charger has switched to the
maintain mode of operation.
MAINTAIN MODE
(FLOAT MODE MONITORING)
When the Charged/Maintaining
(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 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 SC1320 charges and 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.
