Solution:

and battery is weak. Ensure that connections are sound
and power is not being interrupted.
2. Battery has fallen bellow 12.5-V while in Maintenance-
Float mode. This can occur if the battery is connected to
a load, if the battery is sulfated or if there is a bad cell.
Disconnect from any load, check the battery for a bad cell
and restart charger.
