Press to immediately begin charging your properly connected battery. If the button is not pressed, charging should begin in ten minutes.
POWER (green) LED:
The charger is connected to an AC outlet.
BAD BATTERY (red) LED:
The charger has detected a problem with the battery. See Troubleshooting for more information.
CLAMPS REVERSED (red) LED flashing:
The connections are reversed.
CHARGING (yellow/orange) LED lit:
The charger is charging the battery.
CHARGED/MAINTAINING (green) LED lit:
The battery is fully charged and the charger is in maintain mode.
NOTE: See Operating Instructions for a complete description of the charger modes.
A spark near a lead-acid battery may cause an explosion.
Do not start the vehicle with the charger connected to the AC outlet, or it could result in damage to the charger.
The charge rate is measured in amps. The charger will automatically adjust the charging current, based on battery size, in order to charge the battery completely, efficiently and safely. Do not use for industrial applications.
If the Start/Stop button is not pressed within 10 minutes after the battery charger is first powered up, charging will automatically begin, when properly connected to a battery.
When an Automatic Charge is performed, the charger switches to the maintain mode automatically after the battery is charged.
Times are based on a 50% discharged battery and may change, depending on age and condition of battery.
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. Do not continue attempting to charge this battery. Check the battery and replace, if necessary.
Desulfation could take 8 to 10 hours. If desulfation fails, charging will abort and the BAD BATTERY (red) LED will light.
Charge completion is indicated by the CHARGED/MAINTAINING (green) LED. When lit, the charger has switched to Maintain Mode.
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.
The SC1302 maintains 12 volt batteries, keeping them at full charge. It can charge and maintain both small and large 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 recommended.
A minimal amount of care can keep your battery charger working properly for years.
PROBLEM | POSSIBLE CAUSE | SOLUTION |
The POWER ![]() | AC outlet is dead. Poor electrical connection. | Check for open fuse or circuit breaker supplying AC outlet. Check power cord and extension cord for a loose fitting plug. |
The battery is correctly connected, but the ![]() | If the START/STOP button is not pressed, charging should begin in ten minutes. | No problem; this is normal. |
The battery is properly connected, but the ![]() | The battery voltage is low. | Press the START/STOP button to start charging. |
The ![]() | The battery voltage is still below 10V after 2 hours of charging. (or) Desulfation was unsuccessful. Lack of progress is detected and battery voltage is below 14.2V. The battery's initial voltage is below 12.2V and the total input is less than 1.5 Ah. The battery voltage drops to below 12.2V in Maintain Mode. | The battery may be defective. Make sure there are no loads on the battery. If there are, remove them. If there are none, have the battery checked or replaced. The battery may be defective. Have battery checked or replaced. The battery may be overheated. If so, allow the battery to cool. The battery may be too large or have a short circuit. Have battery checked or replaced. The battery capacity is too low, or the battery is too old. Have it checked or replaced. The battery won't hold a charge. May be 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. |
