Inserting Batteries Into Your Hearing Aid

To put in the battery, open the battery door with a fingernail, put the battery into the DOOR with the "+" facing the "red +" on the door. If the battery is upside down, the door will not close.

Variables That Affect Battery Life

There are two variables which affect hearing aid battery life:

1. BATTERY SIZE: The larger the battery, the longer it will last.

2. BATTERY DRAIN: The more advanced the hearing aid circuitry, the shorter the battery life.

Battery Care

1. Store batteries at room temperature. Heat will shorten the life of a battery. Refrigeration is not recommended.

2. Keep the tab on a Zinc-Air battery until you are ready to use it. Zinc-Air batteries are not active until the tab is removed and air is allowed to flow into the cell. By keeping the tab on until you need it, the battery will have longer life.

3. Open up the battery compartments of your hearing aids every night. This will prevent moisture buildup that could affect the performance of the battery and your hearing aids. Always keep your batteries in a protective package. Never carry loose batteries in a purse or a pocket. If batteries come in contact with each other or other metal objects such as coins, they may short out.
4. Never dispose of batteries in a fire as they can rupture and explode. Do not attempt to recharge them.
5. Always keep batteries and hearing aids out of the reach of small children and pets. If a battery is swallowed, see a doctor immediately. For recommended treatment, call the National Button Battery Hotline collect, at 202-625-3333.

6. Always carry extra hearing aid batteries with you to avoid losing benefits provided by your hearing aids in important situations.
7. Completely remove the batteries from your hearing aids if not in use for extended periods of time. Remove dead batteries immediately and dispose in household trash. A totally discharged battery may swell and become difficult to remove later.
8. The amount of battery life you can expect depends on the type of circuits in your hearing aids, power of your hearing aids, and the number of hours of use.
9. Have your hearing aids cleaned and serviced at least twice a year.
