Hearing aids are battery-powered. Whether it’s rechargeable batteries or disposable ones that need to be manually changed, hearing aids need a source of energy. This means that you will have to incorporate battery replacements or time for charging into your daily routine.
The style of battery that you’ll need will depend on your hearing aid brand and model. You get to choose which hearing aid batteries to buy.
Here’s a guide on hearing aid types and brands to look into.
What are the Types of Hearing Aid Batteries
There are two hearing aid battery categories:
You most likely own a device (computer or smartphone) that has its own rechargeable battery. Just like these devices, hearing aids also have a rechargeable battery that needs to be restored with power in order to work each day.
Here are some companies that make hearing aids with rechargeable batteries:
Long-time hearing aid users, who wear devices with rechargeable batteries, recommend placing them in the charger overnight while they are sleeping.
Your hearing aids’ battery life will be mentioned in the manufacturer’s pamphlets that come with your hearing aids. On average, you can expect at least 30 hours of use per charge. Please note that streaming music, media, phone calls, etc. via Bluetooth® will quickly drain your batteries.
Zinc-air Button Disposable Batteries
There’s zinc in disposable batteries, which is why they are lighter in weight and cheaper than lithium-ion. Zinc is environmentally friendly, so it can be recycled, unlike regular batteries.
Disposable batteries have a factory seal that should be peeled off when you are ready to place them in your hearing aids. The sticker protects the hearing aids from getting air into them. As soon as oxygen comes in contact with the zinc, creating zinc oxide, the hearing aid becomes activated. It’s important to keep the backing on until you are ready to place the batteries into your hearing devices.
There are four sizes of hearing aid batteries. Each size is color-coded to lessen confusion. The smallest batteries can last about 3 days, and the larger batteries can last for 22 days.
Here’s a list of battery size from largest to smallest:
The blue size 675 batteries are used for powerful hearing aids that allow maximum amplification. They have generally been used in behind-the-ear (BTE) hearing aids.
The orange size 13 batteries are typically used in BTE hearing aids that are in size medium to large, and provide high levels of amplified sound.
The brown size 312 batteries are generally used in small BTE and in-the-ear (ITE) hearing aids.
The yellow size 10 batteries are used in the smallest hearing aids, i.e. mini-receiver ITE hearing aids and completely-in-the-canal (CIC) hearing aids.
The Lifespan of Hearing Aid Batteries
The lifespan of hearing aid batteries are influenced by:
It’s always a good idea to keep extra batteries with you, no matter how often you use your devices.
3 Tips on Purchasing Hearing Aid Batteries
Hearing Aids and Batteries: The Cost
Battery costs should be taken into consideration when purchasing hearing aids.
Disposable vs. Rechargeable - rechargeable batteries may be more cost-effective than depending on the disposable batteries. Consider your personal preferences. Rechargeable batteries are easier to use than changing out batteries if you have dexterity challenges. If you have an active lifestyle, disposable batteries may be your best option if you are constantly on the go.
Bundled with Hearing Aids - Bundling can be an option. Batteries are normally included with the bundled cost of hearing aids, along with warranties. Bundles usually include as many batteries as you need for the lifespan of your hearing aids.
