Learn about how long disposable batteries last before they need renewing, and what affects their lifetime.
Disposable batteries typically keep a hearing aid powered for three to 10 days before they need replacing, depending on how you use your hearing aids, and on what model you have.
Streaming audio or music to your hearing aids via Bluetooth® uses more power, which requires you to replace the batteries more often.
When you aren’t using your hearing aids, turn them off by leaving the battery drawer open.
A MultiTool can help you handle batteries. It has a magnetic tip to make removing and inserting batteries easier.
Ask your hearing care professional for a MultiTool.
You may hear two or three beeps when it is time to change a battery. This is a warning, giving you notice that the battery may need replacing soon.
If you have a hearing aid with Bluetooth®, this technology will be shut down to conserve power, so it will no longer be possible to use wireless accessories.
The warning beeps will be repeated at moderate intervals until the battery runs out. This may happen shortly after the pre-warning or within the next couple of hours.
You may hear four beeps. This is the last warning before the hearing aid turns off.
Learn the correct way to remove and replace your hearing aid batteries.
If you are unsure about the status of a battery, you can use a battery tester.
Insert the battery in the hearing aid and close the battery door. Close your hand around the hearing aid and hold it up to your ear and listen for the jingle as the hearing aid starts up. If you can hear the sound being played, the battery is functioning.
