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.
