Things You'll Need
Instructions
Rub battery contact points with a clean pencil eraser. The clean eraser will pick up corrosion from the contact points. The contact points are raised metal surfaces or springs located on the bottom of the battery chamber and on the battery chamber cover.
Dip a cotton swab or toothbrush in vinegar and swab away any corrosion that remains on the contact points. Alkaline batteries contain an alkaline, not acid. Because vinegar is a mild acid, it counteracts the alkaline.
Swab the walls and door of the battery chamber if battery fluid has leaked anywhere else in the chamber. Corrosion due to battery fluid has the appearance of a white crust.
Gently sand the contacts with the tip of an emery board if a new battery will still not power the camera. Sanding the contacts will loosen any remaining corrosion. Swab and clean with vinegar again.
Blow debris from the chamber and dry any vinegar residue with canned air before finally replacing the battery and using the camera.
