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.
• The battery is too large or there is a
bank of batteries and it doesn't reach full
charge within a set time period.
Circumstances that could cause an Abort
situation during maintaining:
• The battery is severely sulfated or has a
weak cell and will not hold a charge.
• There is a large draw on the battery and
the charger has to supply its maximum
maintain current for a 12 hour period to
keep the battery at full charge.
