Changing hearing aid batteries is a simple but essential part of maintaining the performance and reliability of your hearing aids. Whether you wear behind-the-ear (BTE), in-the-ear (ITE), or other types, knowing how and when to replace the battery can help prevent unexpected interruptions.
In this guide, we explain how to change hearing aid batteries, how often you should do it, and what to expect from rechargeable options.
Recognising the signs of a low battery can help you avoid sudden interruptions. Most modern hearing aids will alert you with a warning beep or a voice message when the battery is running low. These alerts typically occur several minutes before the device shuts off completely, giving you time to prepare.
Other common signs that your hearing aid battery is running low include:
If you experience any of these issues and your device isn't damaged, replacing the battery will usually resolve the issue immediately.
Tip: Always carry spare batteries with you—especially during travel or long days out.

Battery life varies depending on the type of hearing aid, the battery size, and how often the device is used. Here's a general guide based on battery size:

Rechargeable hearing aids require no battery changes but need to be charged regularly, usually overnight. Most modern rechargeable hearing aids use lithium-ion batteries that cannot be replaced by the user. Instead, you simply recharge them every night using a dedicated charging station.
Tips for rechargeable hearing aids:
Rechargeable hearing aids typically provide between 16 and 30 hours of use on a full charge, depending on the model and usage. Most users can get a full day’s wear from overnight charging, making them very convenient for daily use. The actual battery lifespan, meaning how many years the rechargeable battery remains effective before needing replacement, usually ranges from 3 to 5 years.
Battery life can be affected by factors such as streaming audio, phone calls, and environmental conditions. To ensure optimal performance, it’s important to follow the manufacturer’s charging instructions and avoid exposing the devices to extreme temperatures.
