Operating Instructions - Schumacher SC1323 Owner's Manual

DIGITAL DISPLAY
The display will show the battery VOLTAGE
when the charger is not charging a battery.
When it goes into charging mode, the
display will automatically change to ON (to
show charging has started) and then show
the percent-of-charge of the battery being
charged and either 6 or 12 (the voltage of
the battery, determined by the charger). If
you manually stop the charging process (by
pressing the START/STOP button) before
the battery is fully charged, the display will
show OFF.
NOTE: During charging, the display will
go into sleep mode and will not show the
percentage of charge or voltage of the battery.
To turn the display back on, press any button.
(Battery %) – The Digital Display shows
an estimated charge percent of the battery
connected to the charger battery clamps.
(Voltage) – The Digital Display shows
the voltage at the charger battery clamps
in DC volts, or the voltage of the battery,
depending on what mode the charger is in.
CHARGE RATE
The charger will automatically adjust the
charging current, based on battery size,
in order to charge the battery completely,
efficiently and safely.
RATE SELECTION BUTTON
Use this button to set the maximum
charge rate. Press the button until the
desired charge rate is selected.
– For charging small batteries, such as
those commonly used in garden tractors,
snowmobiles and motorcycles. Also used
to maintain fully charged large batteries.

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
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.
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.
– For charging automotive, marine
and light truck batteries. Not intended for
industrial applications.
BATTERY TYPE BUTTON
Use this button to select the battery type.
– Used in cars, trucks and motorcycles,
these batteries have vent caps and
are often marked "low maintenance" or
"maintenance-free". This type of battery is
designed to deliver quick bursts of energy
(such as starting engines) and has a greater
plate count. The plates are thinner and have
somewhat different material composition.
Regular batteries should not be used for
deep-cycle applications.
– The Absorbed Glass Mat construction
allows the electrolyte to be suspended
in close proximity with the plate's active
material. In theory, this enhances both the
discharge and recharge efficiency. The
AGM batteries are a variant of Sealed
VRLA (valve regulated lead-acid) batteries.
Popular uses include high-performance
engine starting, power sports, deep-cycle,
solar and storage batteries.
–The electrolyte in a GEL cell has a
silica additive that causes it to set up or
stiffen. The recharge voltages on this type of
cell are lower than those for other styles of
lead-acid battery. This is probably the most
sensitive cell in terms of adverse reactions
to overvoltage charging. Gel batteries are
best used in VERY DEEP cycle application
and may last a bit longer in hot weather
applications. If the wrong battery charger is
used on a gel cell battery, poor performance
and premature failure will result.
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 a live grounded
AC outlet.
8. Select the battery type and charge rate.
9. Charging will begin within ten minutes
and finish automatically. (Press the
START/STOP button to begin charging
immediately.)
10. 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.
