Red LED
stays on for
more than
24 Hrs
1. One or more defective or
damaged cells.
2. On-board DC systems are
drawing more current than
the charger can replace.
1. Load test the battery and replace if
necessary.
2. Disconnect the charger’s black
(NEGATIVE) terminal from the battery.
Reapply AC power and only green LED
should now light, if so, battery may

the battery charger.
4. Battery finishing taking
longer than expected.
1. Turn off all DC equipment while
charging.
2. Load test the battery and replace if
necessary.
3. Apply a higher AC voltage source or
reduce the length of the extension
cord.
