Operating Instructions - Schumacher Electric SC1323 Owner's Manual

BATTERY TYPE BUTTON
Use this button to select the battery type.
Standard – 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.
Standard batteries should not be used for deep-cycle applications.
AGM – 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.
GEL – 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.

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 and your vehicle.
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.
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 clamp 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 a live grounded AC outlet.
5. Select the battery type and charge rate.
6. Charging will begin within ten minutes and finish automatically. (Press the START/STOP button to begin charging immediately.)
7. When charging is complete, disconnect the charger from the AC power, disconnect the negative clamp, and finally the positive clamp.
8. A marine (boat) battery must be removed and charged on shore.
AUTOMATIC CHARGING MODE
When an Automatic Charge is performed, the charger switches to the maintain mode automatically after the battery is charged.
BATTERY CHARGING TIMES

Times are based on a 50% discharged battery and may change, depending on age and condition of battery.
ABORTED CHARGE
If charging cannot be completed normally, charging will abort. When charging aborts, the charger's output is shut off and the Bad Battery (red) LED will light. The digital display will
show an error code (see the Troubleshooting section for a description of the error codes). Do not continue attempting to charge this battery. Check the battery and replace, if necessary.
DESULFATION MODE
Desulfation could take 8 to 10 hours. During this time, the display will show "SUL" and the Bad Battery (red) LED will light. If desulfation fails, charging will abort, the display will
show "F02" and the Bad Battery (red) LED will stay on.
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 (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
This unit charges and maintains 6-volt and 12-volt 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.
