Your hearing aid batteries are vital to its function, so it is important to change them regularly, know the warning signs for when they’re running low and be aware of which batteries your device requires.

Batteries for hearing devices are available in four sizes and are colour coded by size. Our simple guide to these in below.

As all hearing devices use batteries it is important to consider their cost and replacement. In some devices, rechargeable batteries are available however, in the majority of hearing aids, you will need to replace the batteries every 10-30 days.

While replacing batteries is relatively easy and can be done by the user, cost is still an important factor. Bay Audio however, offers a service to mitigate this cost a little and keep your hearing device running smoothly. The Bay Audio Battery Club can save you over 50% on the cost of replacement batteries, with the loyalty club offering six batteries for just $3, with the 8th pack free.

Also available for eligible customers, under the Office of Hearing Services Program, is an annual battery and maintenance scheme. Under this scheme, we will maintain your hearing aid and supply batteries of an annual fee.

There are a range of variants that can affect how long your battery can last, these include; how much you use your hearing aid, what settings your hearing aid is on, the battery type and the type of hearing aid.  We estimate your battery can last anywhere from 3-20 days.

There are multiple ways to minimise drain on your battery, which will reduce the number of times you have to change it. These include:

• Removing the battery completely if you aren’t using your device for an extended period of time
• Overnight, turn off your hearing aid and open the door to the battery compartment
• Keeping batteries away from coins or other metal objects which can discharge the batteries
• Keep out of extreme hot or cold temperatures

While your batteries can lose charge very quickly, there can be several indicators that you need to change the batteries in your hearing device. Some hearing aids emit a low beeping tone to alert you to the need of the batteries to be changed, other indicators include the sound you receive becoming distorted or all sound ceasing. Due to the capacity of hearing aid batteries to quickly discharge it is a good idea to carry spare batteries with you at all times.

Hearing aid batteries should be stored at room temperatures in a cool, dry place and away from other metal objects. It is important to remove dead batteries immediately as they can swell and become trapped in the battery compartment.
