However, if you use this battery charger to charge a large battery, such as a marine
deep-cycle battery, that was not fully charged, you may lose some of the battery's
capacity. Therefore, we do not recommend charging a large battery with this unit.
NOTE: The maintain mode technology allows you to safely charge and maintain a
healthy battery for extended periods of time. However, problems with the battery,
electrical problems in the vehicle, improper connections or other unanticipated
conditions could cause excessive current draws. As such, occasionally monitoring
your battery and the charging process is required.
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 8 hours. If desulfation fails, charging will abort, the GREEN LED
will flash, and the display will show CHARGE ABORTED-BAD BATTERY.
ABORTED CHARGE
If charging cannot be completed normally, charging will abort. When charging
aborts, the charger's output is shut off, the GREEN LED will flash, and the
display will show CHARGE ABORTED-BAD BATTERY. Do not continue
attempting to charge this battery. Check the battery and replace, if necessary.
