Rechargeable Hearing Aids

Are you tired of your hearing aid batteries running out unexpectedly? Modern, rechargeable hearing aids are growing in popularity - and for good reason too. Just place your hearing aids in the charging station when you go to bed, and they are ready to use when you wake up in the morning. What’s more - rechargeable hearing aids mean that you don’t have to buy battery replacements or continue throwing away used batteries, which is beneficial for both your wallet and the environment at the same time.

How many hours does it take to recharge the rechargeable hearing aids? 

If the battery is completely drained, then the average charging time is around:

  • 3-4 hours to reach full charge

  • 1 hour to reach 50% charge

  • 1/2 hour to reach 25% charge

Note that the loading time can depend on the age of the battery.

How do I know when the hearing aids are fully recharged?

The recharging process stops automatically when the battery is fully charged. On most hearing aids, the hearing aid has a small light which turns green when the battery is recharged.

How do I know when my battery needs to be recharged?

When the rechargeable hearing aid batteries are almost empty, the hearing aids send out a signal, which typically consists of three short beeps.
The signal indicates that there are about 2 hours of usage left before the hearing aids stop working. The warning sound is repeated every 30 min.

How long does my battery last before it needs to be recharged?

If your battery is fully charged, you can expect to wear your hearing aids all day. However, if you stream sound from another electronic device (such as the TV or your computer) for more than 8 hours, then you might have to recharge your hearing aids during the day.

Rechargeable hearing aids usually run on lithium batteries (the same battery type found in most smartphones) or silver-zinc batteries.

In order to recharge your hearing aids, you need a charging station that comes along with the rechargeable hearing aids when you purchase them. At the end of the day, all you have to do is place the hearing aid in the charger before you go to bed, and the batteries will be fully charged in the morning.

If your rechargeable hearing aids don’t have a battery door, they contain lithium batteries. It takes about 3-4 hours to fully recharge and power your hearing aids for around 24 hours. The battery itself should last as long as the life of the hearing aid, which is around 4-5 years. After that period, you can purchase new hearing aids or send them to the manufacturer to have the rechargeable hearing aid batteries replaced.

Some rechargeable hearing aids are fitted with silver-zinc batteries. The batteries are removable and can be replaced easily by a hearing care professional. You can expect these batteries to last about one year.

Keeping your rechargeable hearing aid batteries healthy

It’s a good idea to always place your hearing aids in the charging station when not in use - that way you also always know where they are. Charging your hearing aid batteries too often will not drain or shorten the battery life. Quite the opposite in fact. However, you should not store your hearing aids in an unplugged charging station, as this might drain the rechargeable hearing aid batteries and shorten the life expectancy. In case you are not going to use your hearing aids for a while, simply turn them off and store them in a safe place.

If your rechargeable hearing aid batteries are silver-zinc batteries, you should not open the battery door when you are not using your hearing aids, like you might do with normal hearing aids. If you are not using your silver-zinc battery-powered hearing aids for three hours and do not have the opportunity to place them in the charging station, you should remove the batteries and put them somewhere where they do not touch each other or other metallic objects.
