The two main types of hearing aid batteries are rechargeable hearing aid batteries and disposable hearing aid batteries. Each offers its own set of pros and cons dependent on your lifestyle and your needs. Let's take a look to help you decide which is right for you, and to better understand the most essential features of your hearing device.
Rechargeable hearing aid batteries, such as those using Lithium-ion technology, are becoming more common due to their convenience. They allow you the freedom to make the most of your day without having to worry about losing power.
According to Miracle-Ear, disposable zinc air batteries are not 100% rechargeable. They come in four sizes and are color-coded to help you remember the right size for your hearing aid. The batteries are air-activated, which means they do not begin working until the colored tab is removed and air enters the battery cell.
