Maintenance and care
A minimal amount of care can keep your battery
charger working properly for years.
1. 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 corro-
sion.
2. Coil the input and output cords neatly when storing
the charger. This will help prevent accidental
damage to the cords and charger.
3. Occasional cleaning of the case of the charger with
a soft cloth will keep the finish shiny and help
prevent corrosion•
