AUTOMATIC CHARGING MODE
When an automatic charge is performed, the charger switches to the
maintain mode automatically after the battery is charged. For a battery
with a starting voltage under 1 volt, use a manual charger to pre-charge
the battery for five minutes, to get additional voltage into the battery.
BAD BATTERY
If charging cannot be completed normally, the charger’s output is shut
off and the red LED will flash. Have the battery checked and replace,
if necessary.
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 8-10
hours. If desulfation fails, the red LED will flash.
COMPLETION OF CHARGE
Charge completion is indicated by the green LED. When solid, the
charger has switched to the maintain mode of operation.
MAINTAIN MODE (FLOAT MODE MONITORING)
When the green LED is solid, the charger has completed charging and
started maintain 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.
