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.
