Aborted Charge

If charging can not be completed normally, charging will abort. When charging aborts, the charger’s output is shut off, and the CHECK BATTERY (red) LED will blink. To reset after an aborted charge, disconnect the battery.

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 10 hours. If desulfation fails, charging will abort and the CHECK BATTERY (red) LED will blink, have the battery checked.

Completion of Charge

Charge completion is indicated by the CHARGED (green) LED. When lit, the charger has stopped charging and switched to the Maintain Mode of operation.

Maintain Mode

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.

General Charging Notes

Fan: The charger is designed to control its cooling fan for efficient operation. Consequentially, it is normal for the fan to start and stop when maintaining a fully charged battery. Keep the area near the charger clear of obstructions to allow the fan to operate efficiently.

13.CALCULATING CHARGE TIME

Use the following table to more accurately determine the time it will take to bring a battery to full charge. First, identify where your battery fits into the chart.

Find your battery’s rating on the chart below, and note the charge time given for each charger setting. The times given are for batteries with a 50% charge prior to recharging. Add more time for severely discharged batteries.
