Generally, there are two types of hearing aid batteries: disposable zinc-air batteries and rechargeable batteries.

Disposable zinc-air batteries

Zinc-air batteries use air as a power source and are activated by oxygen when you remove the tab attached to the battery. Disposable Zinc Air Batteries come in four sizes and work with many types of hearing aids.

Rechargeable batteries

Rechargeable batteries for hearing aids are most often lithium-ion batteries that need to be recharged regularly for three to four hours. Because they are reusable, rechargeable hearing aid batteries are more environmentally friendly than disposable batteries. However, rechargeable batteries also come with downsides, such as the lack of a hearing aid when recharging and the need to carry a charger when traveling. Many hearing aid models come with their own rechargeable batteries.

Disposable Zinc Air Batteries and Rechargeable Batteries

Disposable zinc-air batteries are available in large quantities, are easily replaced by the user, and are suitable for more types of hearing aids than rechargeable hearing batteries. On the other hand, rechargeable batteries are better for the environment and possibly more economical in the long run since you don’t throw them away regularly. Rechargeable batteries can also retain their power longer than zinc batteries if you use Bluetooth and streaming services, and they are easier to handle than small button batteries. However, some types of hearing aids are not suitable for using rechargeable batteries.

Hearing aid battery maker Power One recommends customers check if their hearing aids can hold power for 10 days without having to replace zinc batteries. If so, the hearing aid may be compatible with a rechargeable battery. Consult your hearing care professional or audiologist to help you choose the best battery for your hearing aid.
