Tips- Keep them in their protective packs and storing them at room temperature. Never remove the color-coded tab from a battery until you are ready to install it in your hearing aid. Your hearing aid batteries (or cochlear batteries) should never be stored in a refrigerator, carried loose in your pocket, or allowed to come in contact with other batteries or metal objects.
