Hearing aids are battery-operated electronic devices. They can use either disposable or rechargeable batteries, depending on the model you select. The hearing specialist at New Hartford Hearing Center will teach you how to charge or change your batteries during your fitting appointment.
Additionally, you can rely on New Hartford Hearing Center for your replacement batteries. We carry all hearing aid battery sizes, making it easy for you to find the exact type you need.
Disposable hearing aid batteries
Disposable hearing aid batteries look like small silver buttons. They use zinc-air technology and cannot be recharged. When the battery power is spent, you replace the battery with a new battery.
These batteries produce power when the zinc in the battery meets the oxygen in the air we breathe. The charge in a zinc-air battery can last up to a week. Factors determining battery life include the size of the battery, how many hours a day you wear your hearing aids, and the number and types of functions you use.
Changing a disposable battery is easy. Just open the battery door, take out the old battery, remove the factory sticker from the new battery and wait at least a few minutes before you install the replacement battery. It’s important to expose the battery to air before you install it. This ensures you get a full charge from the new battery.
Disposable hearing aid battery sizes
All hearing aid manufacturers use standard hearing aid battery sizes. Even if you didn’t buy your hearing aids from New Hartford Hearing Center, you can still buy your hearing aid batteries here. Hearing aid battery sizes are coded by color and number. The most common hearing aid battery sizes are:
- Size 10 batteries: Yellow label
- Size 312 batteries: Brown label
- Size 13 batteries: Orange label
- Size 675 batteries: Blue label
The larger the battery, the longer it will last.
If you have issues with vision or dexterity that make it hard to handle small hearing aid batteries and battery doors, talk to the hearing specialist at New Hartford Hearing Center about hearing aids with rechargeable batteries. They may make wearing hearing aids easier for you.
Rechargeable batteries
Hearing aids with rechargeable batteries free you from the hassle of buying and changing disposable batteries. These hearing aids use batteries like those in smartphones, tablets and laptops. With some devices, one charge can last up to 30 hours.
Simply place the hearing aids in their charging station each night. In the morning, your hearing aids are fully charged and ready for use that day. If you forget to charge the battery, a quick 30-minute charge can provide up to eight hours of use.
