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. Activation of the special Desulfation Mode is
indicated by the CHARGING (yellow) LED blinking. If successful, normal
charging will resume after the battery is desulfated. The CHARGING (yel-
low) LED will then stop blinking and stay lit. Desulfation could take up to
10 hours. If desulfation fails, charging will abort. The CONNECTED (yel-
low) LED will remain lit, and the Digital Display will read bad bat.
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. If the 12V DEEP CYCLE battery type was selected, the
CHARGED (green) LED comes on when the battery is charged enough for
normal use.
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 deliver-
ing a small current when necessary. If the battery voltage drops below a
preset level the charger will go back into Charge Mode until the battery
voltage returns to the full charge level, at which point the charger will
return to Maintain Mode. The voltage is maintained at a level determined
by the BATTERY TYPE selected.
NOTE: The charger automatically switches between Charge Mode and
Maintain Mode as necessary. The CHARGED (green) LED will cycle on
when the battery is at full charge and off when the voltage drops below
a preset level and the charger goes into Charge Mode. This cycle will
continue, and the CHARGED (green) LED will stay on for longer periods
of time as the battery becomes more fully charged.
