Battery Enclosure and Batteries
Mix a four-ounce box of baking soda with a gallon of fresh water and fill spray bottle. Spray solution
on all exposed surfaces of the battery compartment and wash down the exposed surfaces of the
batteries and their enclosure. Scrub stubborn areas with the scrub brush. Baking soda will
neutralize any acid that may have collected on these surfaces. Finish by rinsing with water.
Terminals & Lugs
Loose battery terminals and lugs exposed to open air will corrode rapidly. The corrosion will appear
as a white powder or granular foam on the terminals and any nearby exposed metal parts. This is
actually a crystallized form of sulfuric acid, which is extremely corrosive. If it contacts your skin, it will
cause burns unless you rinse it off immediately. Most textile goods that are exposed to this corrosive
will eventually dissolve.
The most common cause of battery system failure is loose or corroded battery terminals and cable
lugs. If any white powdery residue forms between the battery cable lug and the battery terminal, the
