40 Duracell Batteries, Size 10 Zinc Air Hearing Aid Batteries. Duracell Actavair Easy Tab hearing aid batteries have extra long tabs for easier handling. 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. Minimize battery drain by opening the door to the battery compartment when your hearing aid is not in use. This will also aid in preventing moisture buildup in your hearing aid's battery compartment.
