How long do hearing aid batteries last?

Many factors can influence how long each hearing aid battery lasts. The type of hearing aid, the amplification power, and the available features all play a part in battery length. For example, more hearing aid power is required when streaming television or music. Standard hearing aid batteries can last between 3 to 22 days.

How to get the most from your hearing aid batteries

Battery activation tip

Our hearing aid batteries are air-activated, which means they do not begin working until the coloured tab is removed and air enters the battery cell. Remove and discard the tab only when you are ready to use the battery. The tab cannot be reused.

Conserve battery overnight

When not in use, it’s suggested to turn off the hearing aid batteries. To do this all you need to do is open the battery door. The added benefit from leaving the battery door open is that it allows any excess moisture to dry out, this helps extend the life of your hearing aid batteries and your hearing aids.

Storing hearing aid batteries

The ideal temperature for hearing aid batteries is between 10 and 25°C, so it is recommended to keep them in a dry area inside at room temperature.
Due to the small battery size, ensure they are kept out of reach around children.

Battery life length

Get the most out of your hearing aid batteries by turning them off at night and reducing your streaming of television or music.

Rechargeable hearing aids

There are also rechargeable hearing aids such as the ampli-energy, which utilise lithium-ion technology so you can charge your hearing aids overnight like you would with a phone. If changing the batteries on your hearing aids becomes difficult to manage, please speak with a qualified hearing specialist who can explore if rechargeable hearing aids would be suitable.


Why are my hearing aid batteries dying so fast?

If your hearing aid batteries are dying too fast, the battery may be getting depleted by moisture which makes it less reliable. Ensure you follow our tips to get the most from your hearing aid batteries. If you have noticed a change in how long your batteries last, we suggest you visit your local clinic for a free clean and check of your hearing aids.

Should you change both batteries at the same time?

It is not necessary to change both hearing aid batteries at the same time. You will receive a similar performance from two hearing aids regardless of battery life. It is recommended to replace your batteries either when they die or on a regular basis on the same day - whichever works best for you.

What to do with dead hearing aid batteries?

Most hearing aid batteries contain zinc. Whilst convenient, you should never dispose of your zinc batteries in household waste as it is harmful for the environment. Instead look for drop off centres which accept batteries.
