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.
CALCULATING CHARGE TIME 13.
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.
