        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.

Why Zinc Air technology?

Zinc air batteries have an especially high energy density and exhibit an almost flat drain curve. They are therefore the ideal power supply, especially for today´s digital hearing aids.

The air holes of the battery are initially sealed with a protective tab. They are kept in this way, in an “inactive state”, until they are needed. The inherent self-drain of zinc air batteries with protective tab attached amounts to a mere 3% a year. The film is removed when the battery is inserted into the hearing aid. After several seconds of activation time, the battery begins to produce current.

In the activated state (with protective tab removed), zinc air batteries can only be stored for a limited period and should be used as quickly as possible.
