Hearing aids come in a variety of styles, sizes and colors. One thing they all have in common is they rely on batteries to supply them with power. If you’re new to hearing aids, you may be wondering how to choose what type of battery you need. We review how below.
Two Types of Batteries
There are two types of hearing aid batteries: rechargeable and disposable.
Just like your smartphone, tablet and laptop rely on rechargeable batteries, many modern hearing aids do, too. One overnight charge on a docking station can provide you with a full day of listening. Currently, rechargeable hearing aids are only available in larger hearing aid options, like behind-the-ear (BTE) and receiver-in-the-ear (RITE) models.
Before rechargeable hearing aid batteries became available, disposable hearing aid batteries were the only option.
Button batteries, also known as zinc-air batteries, are activated by exposure to oxygen. They’re packaged with a factory-sealed sticker that should remain in place until you’re ready to use them. Once you peel off the sticker, the zinc within the battery will activate within about a minute.
Zinc-air batteries can last up to three years when stored properly in a dry area. Avoid putting this type of battery in the refrigerator, which can cause condensation to build up.
Disposable batteries come in four standard color-coded sizes:
This battery is the longest lasting and is often found in bone-anchored hearing aids and BTE models.
This battery is found in medium-sized BTE hearing devices.
This battery is found in small BTE hearing aids and in-the-ear (ITE) hearing devices.
This is the smallest style of disposable hearing aid batteries. This battery is usually found in completely-in-the-canal (CIC) and mini-receiver-in-canal (mini-RIC) hearing aids.
What Battery Is Right for You?
The battery that is right for you is the battery that’s compatible with your hearing aid. Your audiologist can provide you with this information.
Patients report several challenges related to changing their batteries, including limited information on hearing aid batteries, physical/sensory challenges to the act and the social impact of having to change hearing aid batteries in public places like Frog Hollow Tavern. So, if you are in the market for a new hearing aid, most providers will recommend one with a rechargeable battery option.
