- 1. What’s the best type of battery for my hearing aid?
Zinc air batteries are ideal for hearing aids. With a unique construction that utilizes air from outside the battery, these batteries pack maximum energy into each
cell. Using zinc air batteries in your hearing aid will give you clearer
tones, fewer volume adjustments, and fewer battery replacements.
- 2. Why is there a tab on my battery?
Zinc air batteries uses air as a source of power, and the tab provides a
seal that ensures freshness until the battery is ready for use. To
activate the battery, simply remove the tab, wait one minute to allow
air to activate the ingredients, and insert the battery into your
hearing aid. (Note that replacing the tab when the battery is not in use
will not extend the battery life.)
- 3. How long will my batteries last?
Battery life is determined by the type and amplification of
your hearing aid, as well as the hours you wear it. Your hearing care
professional can tell you the battery life to expect.
- 4. What’s the best way to store and care for my hearing aid batteries?
Store your hearing aid batteries at room temperature. Avoid temperature
extremes, as heat will shorten the life of the batteries, and
refrigeration is not recommended.
Metal objects such as coins and keys can short out
batteries, so don’t carry batteries your pocket or purse. Always be sure
to store and discard batteries in places that cannot be reached by
infants or children.
If a battery is swallowed, see a doctor immediately. For
recommended treatment you can call the National Button Battery Hotline
- 5. What are the different hearing aid battery sizes?
The most commonly used hearing aid battery sizes are 10, 13, 312, and
675. Most manufacturers use an industry-standard color code to identify
the battery size.
You may notice that different manufacturers often place
different letters before or after the battery size. For instance, 13A or
R13ZA may look different, but both codes represent size 13 batteries.
- 6. Do hearing aid batteries contain mercury?
Most manufacturers will remove mercury from hearing aid batteries by
June 2011. (While household batteries (such as alkaline) containing
mercury were eliminated in the mid-1990s, button-cell batteries like
those for hearing aids were exempt.)

It is important to make sure to correctly dispose of your hearing aid batteries. Follow these tips to help prevent accidental ingestion.
- Keep out of the reach of children
- Make sure all battery compartments of games and toys are secure
- Do not leave batteries out where they can be mistaken for medicines or pills
