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 SC2 maintains both 6 and 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 recommended.

13. 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.
• 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.
