Hearing Aid Batteries

Choosing the right hearing aid battery

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 are the heartbeat of your hearing aids; they are essential to your ability to hear and enjoy the world around you. When you need to replace your hearing aid batteries, remember they can come in a range of different sizes from several brands, and each type varies in terms of size, compatibility, and lifespan.

Not all batteries will work in your hearing aid: below you can find the key information you need to know before choosing a battery for your hearing aids.

When to change hearing aid batteries?

In general, the life of a specific hearing aid battery is between 3 and 22 days. This duration varies depending on the type of hearing aid, the type of battery and the length of time the device is used. If you find that the sound is distorted or you need to increase the volume more than usual, your hearing batteries may need to be replaced. Some hearing aids will beep briefly when the battery is low. You must then change the batteries as soon as you hear this beep.

To avoid failure of your hearing aid, we recommend that you always have spare batteries with you. Also take care not to put your spare batteries in contact with metallic objects (coins, keys, etc.) as they may discharge.

Hearing aid battery sizes

Hearing aid batteries come in four standard sizes: 10, 13, 312 and 675. To help you identify which one you'll need, all manufacturers use standard colour codes on their packaging and zinc air battery tabs.

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.

Rayovac size 10 yellow hearing aid batteries were brought to market in 1986. This made possible the introduction of the smaller hearing aids that are so common today.

How to Recycle Hearing Aid Batteries

Learning how to recycle hearing aid batteries is just one of the many challenging aspects of adapting to your new hearing aids and the small hearing aid batteries that power them. Not only are they small and can be lost easily, they also need to be changed routinely. How long they actually work will depend on the size of the battery, the power level of your hearing aids and if you are using wireless features.

On average, a small size 10 battery will last three to five days; a size 312 for seven to 10 days; a size 13 will last ten to fourteen days; and a size 675, the biggest battery, should run for anywhere from two weeks to seventeen days. Because you are regularly changing your hearing aid batteries, you may be tempted to throw the used button cell or zinc air batteries into the trash. While convenient, tinydisposing of your old hearing aid batteries in your trash may actually harm the environment.

How do I dispose of empty batteries?

Old hearing aid batteries should no longer be used in hearing aids, but should be disposed of when they have expired or their power has been exhausted.  Like all other batteries, empty hearing aid batteries must not be disposed of with household waste, as they are harmful to the environment and health. You can collect the empty batteries in a special battery collection box or can and dispose of them free of charge at a collection point or directly in an Amplifon branch. 

Most municipalities have drop-off centers with recycling drop-off boxes for used batteries. The batteries will then be processed and the toxic metals removed and sold for re-use in various industries.This is the most environmentally friendly solution for disposal.
