Automatic Charging Mode
When an Automatic Charge is performed, the charger switches to the
MaintainMode(seebelow)automaticallyafterthebatteryischarged.
Aborted Charge
If charging can not be completed normally, charging will abort. When
charging aborts, the charger’s output is shut off, and the CHARGING
(yellow)LEDwillblink.Toresetafteranabortedcharge,eitherdisconnect
the battery or turn off the charger.
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 8 to 10 hours. If
desulfationfails,chargingwillabortandtheCHARGING(yellow)LEDwill
blink.
Completion of Charge

the charger has switched to the Maintain Mode of operation.
Maintain Mode (Float-Mode Monitoring)
WhentheCHARGED(green)LEDislit,thechargerhasstartedMaintain
Mode. In this mode, the charger keeps the battery fully charged by
delivering 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.
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.
Power Saving Mode
The charger has an internal relay that switches the power transformer on
and off automatically. This means, that the charger uses very little power
when in standby mode or maintain mode.
