Hearing Aid Battery Types
Hearing aid technology has changed a great deal, but one thing remains constant — hearing aids need power. The most common way are disposable batteries, though rechargeable hearing aids are becoming more popular.
Standard Hearing Aid Batteries
Most of today’s hearing aids that are powered by disposable batteries use zinc-air batteries, the small, disc-shaped batteries that are sometimes called “button batteries.” These batteries come in a variety of types and sizes for use in different types of hearing aids. Depending on their size and type of hearing aid they’re powering, they can last from anywhere between 3 to 20 days before needing to be replaced.
Rechargeable Hearing Aid Batteries
Rechargeable hearing aid batteries are convenient and reliable. The technology is still new and there are important differences to consider.
Not all rechargeable hearing aids are appropriate for all types of treatable hearing loss.

Sizes of Hearing Aid Batteries
The Different Sizes, Lifespans, and Color Tabs
There are five standard battery sizes, with four of them being the most commonly used. Different styles of hearing aids require different levels of power. Generally speaking, the larger the hearing aid, the larger its battery. Similarly, the more severe the hearing loss, the larger the hearing aid needed, and the larger the battery needed to power the device.
In order to avoid confusion, each one of these batteries has a distinct name and corresponding color.
Lifespan: 3 to 7 Days
Lifespan: 3 to 10 days
Lifespan: 6 to 14 days
Lifespan: 9 to 20 days
How Hearing Aid Batteries Are Activated
Zinc-air batteries get their name from how their power is activated. You’ll notice that each cell is covered with a sticker, which keeps them sealed until they are to be used. Once the sticker is removed from the cell, air activates the battery and it is ready for use. Some experts recommend waiting as many as five minutes after you’ve activated the battery before placing it into your hearing device.
You cannot “deactivate” your battery by placing the sticker back on the cell, so be sure you plan to use it if you are going to remove its seal.
How to Store Hearing Aid Batteries
Zinc-air batteries should be stored in an environment that is dry and standard room temperature. High-temperature exposure can cause damage, decreasing their lifespan and effectiveness.
Storing batteries in the refrigerator or in the freezer will not extend their shelf life. In fact, doing this can create condensation in the cells once they’re removed from cold storage, and, in effect, will damage the batteries and possibly your hearing aids, too.
Stick to dry, room temperature spaces for best performance, and make sure to use your oldest batteries first.
Do you have questions about your batteries?
Rechargeable Hearing Aid Batteries
Most people don’t love changing hearing aid batteries. Peeling off tabs and getting them inserted into the battery compartment the correct way have caused headaches for many people, especially those with dexterity or vision issues.
Rechargeable hearing aids make this easier. Whenever the hearing aids are removed, they can be stored in their case which also doubles as a charging station, so if you’re familiar with rechargeable earbuds, this is essentially the same. A few hours of charging is all it takes to power the hearing aids for 24 hours or more of use.
It may not seem like much, but the cost of replacing traditional batteries can add up. A pair of hearing aids with traditional batteries can burn through over 100 batteries per year, equaling $75-100 annually. Multiply that cost times each year you wear your hearing aids, and a rechargeable hearing aid suddenly represents significant savings.
Imagine that you’re in the middle of dinner, or that you’re having an important conversation and suddenly your hearing aid dies. It’s a frustrating experience to say the least. What’s more, you forgot to bring spare batteries! Most hearing aid wearers have a dead battery story, and having a dead aid always seems to happen at the worst times. Provided you put your hearing aids in the charger each night, you will never get stuck again.
Ease of Use
Traditional hearing aid batteries are small and can be difficult to insert into the hearing aid. Rechargeable hearing aids are easy to handle and it is simple to slip them into the charging case. Those with dexterity and vision issues are especially thankful for this new capability.
