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 SC1279 maintains 12 volt batteries,
keeping them at full charge. It can charge
and maintain both small and large
batteries.
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.
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.
• 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 clipped together, on or
around metal, or clipped to the cables.
