Everything You Need to Know About Hearing Aid Batteries
Your hearing aids require a steady power supply in order to work properly, because even subtle changes in power output can affect performance, clarity, and volume control. Different hearing aids require different types of batteries — based on the size and power requirements of the hearing aid — to work properly. There are many variables that determine how long your battery will power your hearing aids.
A standard “zinc-air” battery lasts anywhere from three to 22 days, depending upon the type of hearing aid, the capacity of the battery, and the amount of hearing aid use throughout each day. The smallest hearing aid batteries, used for 12 to 16 hours per day, may need to be changed every three or four days, while the largest hearing aid batteries used for only a couple hours each day may go several weeks without needing to be changed.
Rechargeable Hearing Aids
Rechargeable hearing aids are more reliable, less of a hassle, and more powerful than conventional batteries. See the difference you’ll be able to hear with our rechargeable hearing aid options.

- Peace of mind: Enjoy continuous, stable, and uninterrupted power throughout your day.
- A quick charge: Recharge your batteries while you sleep, and enjoy all-day power in the morning.
- Stress-free maintenance: Avoid the hassle of buying and installing disposable batteries.
- Something for the environment: Rest assured one eco-friendly pair of rechargeable batteries equals 200 disposables.
Lithium-Ion Rechargeable Batteries
You might recognize the term “lithium-ion battery” from other electronics around your house, like your smartphone or laptop. Now this technology is available in some of the latest hearing technology.
No more fiddling with batteries constantly. Every night, just place your hearing devices in the charger, and in the morning, they’re ready to go for a full day. This battery has a high energy density, which means its small size packs a lot of power — with a short charge time, you get over 24 hours of continuous power, even if you stream audio from a mobile device.
The battery is sealed up inside your hearing aid, so it’s protected from moisture and dust. Plus, the typical lifespan of a lithium-ion battery is around the same lifespan as your hearing instruments, so you don’t have to worry about getting the battery replaced.
How to Get Rechargeable Hearing Aids
Whether you currently own or are looking to invest in hearing aids, rechargeable hearing aid batteries could be an option for you. New technology generally comes with the rechargeable feature, though some can be retrofitted for this option. Contact us for more info.
Different Types of Batteries
There are four main sizes of batteries, each with a specific color-coded package: size 10 (yellow), size 13 (orange), size 312 (brown), and size 675 (blue). The battery size you need is typically based on the size and style of your hearing aid.
Standard hearing aid batteries are zinc-air, which are activated when exposed to air, so it is very important to keep them sealed in their packages prior to use. Never open packages to move batteries to a single container; keep the packages sealed until the batteries must be used in the hearing aids, or you may end up with a dead battery. Don’t buy batteries if the seal is broken.
