If charging cannot be completed normally, charging will abort. When charging aborts, the char-
ger’s output is shut o and the CHARGING (yellow) LED will ash. Do not continue attemp-
tiong to charge this battery. Check the battery and replace, if necessary.
Desulfation could take 8 to 10 hours. If desulfation fails, charging will abort and the CHARGING
(yellow) LED will ash.
Charge completion is indicated by the CHARGED/MAINTAINING (green) LED. When puls-
ing, the charger has switched to the maintain mode of operation.
When the CHARGED/MAINTAINING (green) LED is pulsing, the charger has started main-
tain mode. In this mode, the charger keeps the battery fully charged by delivering a small
current when necessary. If the charger has to provide its maximum maintain current for a
continuous 12 hour period, it will go into abort mode (see Aborted Charge section). This is
usually caused by a drain on the battery or the battery could be bad. Make sure there are no
loads on the battery. If there are, remove them. If there are none, have the battery checked
or replaced.

vehicle, improper connections or other unanticipated conditions could cause excessive current
draws. As such, occasionally monitoring your battery and the charging process is required.
A minimal amount of care can keep your battery charger working properly for years.
• Clean the clamps each time you are nished charging. Wipe o any battery uid that may have
come in contact with the clamps to prevent corrosion.
• Occasionally cleaning the case of the charger with a soft cloth will keep the nish shiny and
help prevent corrosion.
• Coil the input and output cords neatly when storing the charger. This will help prevent acci-
dental damage to the cords and charger.
