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, clipped to the handle, on or around metal, or clipped to the cables.
