Times are based on a 50% discharged
battery and may change, depending on age
and condition of battery.
CHARGE COMPLETION AND MAINTAIN
MODE (FLOAT MODE MONITORING)
Charge completion is indicated by the
green LED and the digital display
showing FULLY CHARGED AUTO
MAINTAINING. This means that the
charger has stopped charging and
has switched to the Maintain Mode of
operation. NOTE: 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 SC1352 maintains 12 volt batteries,
keeping them at full charge. It is not
recommended for industrial applications.
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.
DESULFATION MODE
If the battery is left discharged for an
extended period of time, it could become
sulfated and not accept a normal charge.
If the charger detects a sulfated battery,
the charger will switch to a special mode
of operation designed for such batteries.
If successful, normal charging will resume
after the battery is desulfated. Desulfation
could take up to 8 hours. If desulfation
fails, charging will abort and the display
will show CHARGING ABORTED BAD
BATTERY.
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 CHARGING ABORTED
BAD BATTERY. Do not continue
attempting to charge this battery. Check
the battery and replace, if necessary.
USING THE ENGINE START SETTING
Your battery charger can be used to jump
start your car if the battery is low. Follow
all safety instructions and precautions for
charging your battery. Wear complete eye
protection and protective clothing.
WARNING: Using the ENGINE START
setting WITHOUT a battery installed in
the vehicle could cause damage to the
vehicle’s electrical system.
NOTE: If you have charged the battery
and it still will not start your car, do not
use the Engine Start setting, or it could
damage the vehicle’s electrical system.
Have the battery checked.
1. Set the ON/OFF switch to the OFF
position.
2. With the charger unplugged from the
AC outlet, connect the charger to the
battery, following the instructions given
in sections 6 and 7.
3. With the charger plugged in and
connected to the battery and chassis,
set the ON/OFF switch to either the
12V or 24V position, press the
Rate Selection button until the
Engine Start LED is lit, and then
press the START button.
4. If the battery is properly connected the
Engine Start LED will light solid
and the display will show ENGINE
STARTING ON. If display shows
CONNECT CLAMPS, check the
battery connections. When the Engine
Start output is enabled, the display will
show READY.
5. Crank the engine until it starts or 5
seconds pass. If the engine does
not start, wait a few minutes before
cranking again. This allows the
charger and battery to cool down.
NOTE: After 3 minutes in Engine Start
mode, the charger will enter into a cool-
down period of 180 seconds, to allow the
charger and the battery to cool down.
NOTE: During extremely cold weather,
or if the battery is under 2 volts, use the
Boost setting for 5 minutes before
cranking the engine.
