Choosing The Right Battery For Your Hearing Aid

Hearing Aid Battery Chart

There are four different hearing aid battery sizes: 10, 13, 312, and 675. Manufacturers use an industry-standard color code to identify the battery size. Different battery sizes are used to power different types of devices. In general, the larger the battery the greater the power. You can find which type of battery your device requires by referring to your hearing device’s manufacturer’s manual.

Zinc air batteries use air as an active ingredient in fueling the battery. The peel off tab provides a seal that ensures freshness until the time of use. Once you peel or remove the tab off the battery, the air from outside of the battery begins to react with the zinc inside of the battery, this reaction is what charges up or powers the battery. To properly activate the battery, remove the tab and wait one to five minutes to allow air to fill and fully charge the battery, then, insert the battery into your hearing aid. Note: replacing the tab when the battery is not in use will not extend the battery life.

When the tab is removed and the battery has been aired up properly, make sure that you are not forcing the battery door closed. Check that the battery is inserted correctly before closing the hearing aid battery door.

Tips and Tricks

  • Leave new batteries sealed in their original packages
  • Do not remove the tab on your zinc air battery until you are ready to use it
  • Store batteries at room temperature
  • A fresh battery has more power than an aged battery. Therefore, review expiration dates on the back of battery packages prior to purchase
  • Store and discard batteries in places that cannot be reached by infants or children

Things That Affect Hearing Aid Battery Life

Hearing aid batteries typically have a long shelf life (up to three to four years) if stored properly. Hearing aid batteries themselves are sealed by use of a sticker, which blocks oxygen from entering the battery and reacting with the zink inside. When the sticker is removed, oxygen enters the battery through small holes and reacts with he zinc, the battery then becomes “active”. After removing the sticker, waiting one (1) to five (5) minutes (allowing the hearing aid battery to fully charge up) prior to inserting the hearing aid battery into the hearing aid will provide a longer battery life.

Hearing Loss – The degree of a person’s hearing loss will also affect the life of a hearing aid battery.  As the severity of hearing loss increases, the hearing aid is required to provide more amplification. This increases the amount of current that the hearing aid requires, which reduces battery life.

Hearing Aid Use – Hearing aids have different amounts of battery drain and can vary from manufacturer to manufacturer. Different hearing aid technology platforms and features can also affect hearing aid battery life. Wireless streaming will also cause a higher drain on a battery and shorten the battery lifespan.

Extreme Heat or Cold – Extreme cold temperatures will result in lower battery voltage. Extreme heat accelerates the chemical reaction in the battery itself. Both will reduce the lifespan of a hearing aid battery.

Storage – The ideal place to store hearing aid batteries is in a room temperature, dry location. Storage in the bathroom, refrigerator, and car are not recommended. Hearing aid batteries should be kept in their original packaging or in a “battery caddy”.

Contact with metal objects like coins or keys can shorten or reduce battery lifespan.

Do not leave batteries within reach of children or pets! Hearing aid batteries can cause serious injury if ingested.

If ingested please contact the National Battery Ingestion Hotline immediately at 1-800-222-1222.

Disposal – All hearing aids batteries sold today are mercury free, meaning that they are environmentally safe and may be disposed of in regular the garbage. Do not burn.
