Maintenance And Care - Schumacher Electric SE-2352-CA Owner's Manual

NOTE: During extremely cold weather,
or if the battery is under 2 volts, boost
the battery for 5 minutes before cranking
the engine.
6. If the engine fails to start, use the
35A Boost rate for 5 minutes before
attempting to crank the engine again.
7. After the engine starts, move the switch
to the OFF position and unplug the AC
power cord before disconnecting the
battery clips from the vehicle.
8. Clean and store the charger in a dry
location.
NOTE: If the engine does turn over but
never starts, there is not a problem with
the starting system; there is a problem
somewhere else with the vehicle. STOP
cranking the engine until the other problem
has been diagnosed and corrected.
AUTOMATIC CHARGING MODE
When an Automatic Charge is performed,
the charger switches to the maintain mode
automatically after the battery is charged.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging aborts,
the charger's output is shut off and the
BOOST/CHARGING
LED will flash. To reset after an aborted
charge, unplug the charger from the AC
outlet, wait a few moments and plug it
back in.
DESULFATION MODE
Desulfation could take 8 to 10 hours. If
desulfation fails, charging will abort and
the BOOST/CHARGING
orange) LED will flash.

12. MAINTENANCE AND CARE

A minimal amount of care can keep your
battery charger working properly for years.
• Clean the clamps each time you are
finished charging. Wipe off any battery
fluid that may have come in contact with
the clamps to prevent corrosion.
• Occasionally cleaning the case of the
charger with a soft cloth will keep the
finish shiny and help prevent corrosion.

COMPLETION OF CHARGE
Charge completion is indicated by the
CHARGED/MAINTAINING
LED. When pulsing, the charger has
switched to the maintain mode of
operation.
MAINTAIN MODE
(FLOAT-MODE MONITORING)
When the CHARGED/MAINTAINING
(green) LED is pulsing, 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 SE-2352-CA charges and maintains
12 volt batteries, keeping them at full charge.
NOTE: The maintain mode technology
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 required.
• Coil the input and output cords neatly
when storing the charger. This will help
prevent accidental damage to the cords
and charger.
• Store the charger unplugged from the AC
power outlet in an upright position.
• Store inside, in a cool, dry place. Do not
store the clamps on the handle, clipped
together, on or around metal, or clipped
to the cables.
