Hearing aid batteries
Widex Hearing Aid Battery
Hearing aid batteries from power one come from a long tradition: “Made in Germany”, they are among the world’s top-selling batteries. The reasons for their extraordinary success is: they combine the highest quality and reliability, an extremely long life and maximum comfort. At power one, every battery is tested before it leaves the works – 100%. The comfort packaging then receives a quality seal, which safely seals and protects it. The rustproof batteries themselves have an outstanding service life, especially where high power demands are concerned. Behind all this is a special, patented technology that enhances the cell voltage.
Sizes of disposable hearing aid batteries
Hearing aids come in many different sizes and styles and with different power needs. Larger hearing aids require larger batteries. Additionally, hearing aids for people with severe or profound hearing loss typically require more power and larger batteries.
There are four sizes of hearing aid button batteries available on the market. The sizes from smallest to largest are: 10, 312, 13 and 675. Hearing aid batteries are all smaller than the diameter of a dime:

Battery life for hearing aid batteries
Non-rechargeable hearing aid batteries can last anywhere from five to 14 days, based on a 16-hour day of wear. This is dependent upon the size of the battery and power needed by the hearing aid. Typically, smaller batteries have shorter battery life than larger ones.
The average lifespan of hearing aid batteries is as follows:
- Size 10 – three to seven days
- Size 312 – three to 10 days
- Size 13 – six to 14 days
- Size 675 – nine to 20 days
If you are experiencing shortened battery life, there may be an issue with the hearing device. In this case, you should consult your user manual or contact your hearing healthcare professional to make sure everything is working properly.
