Hearing aid batteries

Battery sizes and types for your hearing aid

Many of our hearing aids require batteries of various sizes to keep you hearing and get the most out of your hearing aid. Hearing aid batteries vary in size and cost; At Amplifon we will make sure the right battery is supplied and in stock to suit your purchase.

Hearing aid batteries include a shield that prevents damage to the hearing aid. This is why only specific batteries should be used. Do not use another type of battery, especially batteries for watches, because they are not suitable for your device and may damage it. Make sure your batteries are fresh to ensure clear sound without distortion.

The best place to purchase batteries for your hearing aid is at your local Amplifon clinic to ensure the batteries work the best with your hearing aids, where you will find all battery models, presented with a distinctive color code to help you always choose the right model.

Hearing aid zinc air battery sizes

Disposable zinc air batteries come in 4 sizes and are color coded to help you remember the right size. The batteries are air-activated, which means they do not begin working until the colored tab is removed and air is able to enter the battery cell. Remove and discard the tab only when you are ready to use the battery. There is no need to place the tab back on the battery.

Hearing aid batteries come in four standard sizes: 10, 13, 312 and 675.

Size 10 hearing aid batteries

Size 10 batteries are mainly used in mini receiver in the ear (RITE) and completely in canal (CIC) hearing aids. They are 5.8mm x 3.6mm in size and all manufacturers use the yellow colour code to identify them. Their size makes them ideal for use in the smallest hearing aids. Each battery usually lasts for approximately 3-10 days.

Size 13 hearing aid batteries

Size 13 batteries are most commonly found in behind the ear (BTE) and in the ear (ITE) hearing aids. They are 7.9mm x 5.4mm in size and use an orange colour code. These batteries have a lifespan of approximately 6-14 days.

Size 312 hearing aid batteries

312 hearing aid batteries use a brown colour code and the dimensions are 7.9mm x 3.6mm. You may find them in mini BTE, RITE and in the canal (ITC) hearing aids. They tend to last between 3-10 days.

Size 675 hearing aid batteries

Size 675 batteries use a blue colour code and are usually reserved for use in power BTE hearing aids. While they are the largest on this list at 11.6mm x 5.4mm in size, they also tend to last the longest. In fact, each one can last between 9- 20 days.

Is it time to change batteries?

In general, the lifespan of a specific hearing aid battery is between 3 and 22 days. This time varies depending on the type of hearing aid, the type of battery and the duration of use of the device.

If you notice that the sound is deformed or you need to increase the volume more than usual, your batteries may need to be changed. Some hearing aids emit a slight beep when the battery is low. It is then necessary to change the batteries as soon as you hear this sound signal.

To avoid a breakdown of your hearing instrument, we advise you to always have spare batteries with you. Be careful not to put your spare batteries in contact with metal objects (coins, keys ...) as they may be discharged.
