MAINTAINING A BATTERY
The SC1321 maintains both 6 and 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
nished charging. Wipe off any battery
uid 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
nish 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.
