Hearing Aid Batteries


Our team wants you to be fully educated regarding every aspect of hearing aid technology, including batteries.

Most hearing aid batteries are zinc-air batteries, which look like small disks. This kind of battery can't be charged again, so it has to be thrown away when it's done.

There are five sizes of batteries for hearing aids. The right one for you depends on how your hearing aids are made and how big they are. The hearing aid industry has made it easier to buy new batteries by marking the packages with colors and numbers. The sticky label on the back of the battery is also color-coded:

Benefits of battery hearing aids

  • Microphone

    Collects and absorbs the sound in the environment one is in and converts the soundwaves into electrical signals.

  • Amplifier

    Amplifies the electrical signals and some hearing aids adjust these signals to meet specific hearing preferences.

  • Receiver

    Also referred to as the speaker, sends the electrical signals to the inner ear where they experience more processing before traveling to the brain.

  • Power Supply

    The last component of all hearing aids is the power supply which contains batteries that enable the device to run.

How to get more power from your zinc-air batteries

There are several ways to prolong your batteries' lives if you have disposable hearing aid batteries. Here are some of the best tips for prolonging the life of your zinc-air batteries.

  • Switch the hearing aids off at night if you aren't wearing them. This will save power.
  • When you turn them off, open the battery door and leave it open overnight. Any moisture or condensation will dry overnight, extending your battery life.
  • Store your hearing aids at room temperature, and don't leave them in the bathroom or any other humid room. Your battery life can be depleted by both humidity and heat.

Rechargeable Hearing Aids

The technology for hearing aids is evolving. It's now possible to use rechargeable hearing aids rather than disposable batteries that must be replaced daily.

This is a built-in battery within the hearing aid. All you have to do is put your hearing aids overnight on the charger, and you will have a full day of power in the morning. Some fast charge options will also allow you to charge your devices within 30 minutes.

Advantages of rechargeable hearing aids

  • More convenient

    You just put the hearing aids in the charging dock overnight to charge, and your hearing aids are packed and ready to go in the morning. You don't have to remember to buy batteries or bring spares because your battery won't let you down at the most inopportune moments anymore.

  • More environmentally friendly

    Batteries are relatively tricky to recycle, and most people do not ensure they are disposed of carefully. Of course, rechargeable batteries must still be appropriately disposed of, but this is far less common than the typical hearing aid battery.

  • Better for the less dextrous

    You don't have to bother with replacing small batteries. The small size of disposable hearing aid batteries and hearing aids may be tricky to handle if someone has vision or dexterity problems.

  • There is no need to hold back when using your hearing aids

    Lithium-ion rechargeable batteries can keep up with all of today's new technology's power needs while holding enough charge for an entire day of the hearing.

  • No other charges

    There are no extra costs for rechargeable hearing aids. The batteries last for several years, usually for the life of the hearing aid itself.

When purchasing a hearing aid, there are several other things to consider, so it's crucial to think about the right hearing aid for you in detail with your hearing care provider. Contact us to set up a consultation today. If you still have questions, we're here to help.
