Aborted Charge
If charging cannot be completed normally, charging will abort. When charging aborts, the
charger’s output is shut off and the CHECK BATTERY LED will blink. In that state,
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 BATTERY 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 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
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
LED will stay on for longer
periods of time as the battery becomes more fully charged.
Maintaining a Battery
The Schumacher SI-200A is a battery maintainer that maintains 12 volt batteries,
keeping them at full charge. It can charge small batteries and maintain both small and
large batteries. If you are maintaining a fully charged large battery, you are 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.
13. MAINTENANCE INSTRUCTIONS
13.1 After use and before performing maintenance, unplug and disconnect the battery charger
(see sections 6, 7 and 8).
13.2 Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery connectors,
cords, and the charger case.
13.3 Ensure that all of the charger components are in place and in good working condition,
for example, the plastic boots on the battery clips.
13.4 Servicing does not require opening the unit, as there are no user-serviceable parts.
13.5 All other servicing should be performed by qualied service personnel.
14. MOVING AND STORAGE INSTRUCTIONS
14.1 Store the charger unplugged, in an upright position. The cord will still conduct electricity
until it is unplugged from the outlet.
14.2 Store inside, in a cool, dry place.
14.3 Do not store the connectors clipped together, on or around metal, or clipped to cables.
14.4 If the charger is moved around the shop or transported to another location, take care to
avoid/prevent damage to the cords, connectors and charger. Failure to do so could result
in personal injury or property damage.
