Battery Connection Indicator
If the charger does not detect a properly connected battery, the CHECK
LED will light. Charging will not begin if the CHECK LED is on.
Automatic Charging Mode
When an Automatic Charge is performed, the charger switches to the
Maintain Mode (see below) automatically after the battery is charged.
For a battery with a starting voltage under 0.2 volts, use a manual
charger to pre-charge the battery for ve minutes to get additional
voltage into the battery.
Aborted Charge
If charging cannot be completed normally, charging will abort. When
charging aborts, the charger’s output is shut off and the CHECK LED
will blink. The charger ignores all buttons. To reset after an aborted
charge, unplug the charger from the AC outlet, wait a few moments
and plug it back in.
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 CHECK LED
will blink.
Completion of Charge
Charge completion is indicated by the CHARGED LED. When lit, the
charger has switched to the Maintain Mode of operation.
Maintain Mode (Float-Mode Monitoring)
When the CHARGED 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 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.
Maintaining a Battery
The Schumacher SC-200A is a battery maintainer that maintains both
6 and 12 volt batteries, keeping them at full charge. It can charge
small batteries and maintain both small and large batteries. If you are
• 12 •
maintaining a fully charged large battery, you will be properly utilizing
the battery charger. However, if you were to 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.
This would cause the large battery to be unable to hold a charge and
become useless. Therefore, we do not recommend charging a large
battery with this unit.
NOTE: The maintain mode technology utilized in Schumacher
maintainers 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 recommended.
CALCULATING CHARGE TIME13.
