Hearing Aid Batteries
Powering Your Hearing Aids
Your hearing aids are sophisticated, high-performance tools, but even the smartest devices need reliable power. The right battery ensures consistent sound quality, proper device function, and a seamless user experience. Yet not all batteries are the same, and the choices may seem confusing. This page helps you understand battery types, sizes, care tips, and what to expect so you get the most from your hearing aids.
Types of Hearing Aid Batteries
Rechargeable Batteries
Modern hearing aids come with rechargeable options, often lithium-ion technology. Benefits of rechargeable batteries include:
Cost Savings
Instead of replacing tiny batteries every week, simply recharge once a day. Many devices use built-in lithium-ion batteries designed to last for years.
Reliable Power
Rechargeable systems provide steady, uninterrupted performance so you can go about your day without worrying about losing sound
Easy Overnight Charging
Place your hearing aids in their charger before bed and wake up to a full day of power.
Low Maintenance
Eliminate the hassle of purchasing, handling, and swapping out disposable batteries.
Built-in Convenience
Most rechargeable batteries only need replacement once every year or two, often during your routine checkup.
Eco-friendly Choice
A single set of rechargeable batteries can take the place of up to 200 disposable ones, reducing waste and protecting the environment.
Additionally, some rechargeable systems also allow a fallback to disposable batteries when needed (for example, during a remote camping trip or an extended power outage).
Disposable (Zinc-Air) Batteries
This is the more conventional type of hearing aid battery. Traditional zinc-air batteries can last anywhere from a few days to several weeks. The lifespan depends on factors such as the size of the battery, the style of hearing aid it powers, and how many hours per day the device is worn.
You can extend the life of your batteries with a few simple habits:
- Turn off your hearing aids when they’re not being used.
- Open the battery door at night to allow moisture to evaporate and conserve power.
- Remove the battery entirely if you won’t be wearing your hearing aids for an extended time, such as overnight or during travel.
Battery Sizes & How They’re Labeled
Hearing aid batteries use standard sizes that are universal across brands. This simplifies shopping and ensures compatibility.
| Size | Color | Typical Use |
|---|---|---|
| 10 | Yellow | Small in-the-ear (ITE/ITC, CIC) models |
| 312 | Brown | Receiver-in-canal (RIC), some in-ear models |
| 13 | Orange | Behind-the-ear (BTE), more powerful devices |
| 675 | Blue | Power BTEs and devices needing extra energy |
Care Tips to Get the Most from Your Batteries
- Store batteries at room temperature in a dry place. Heat, cold, and moisture can degrade performance.
- Wait 30-60 seconds after opening so the battery “breathes.” Inserting too quickly can shorten battery life.
- Clean battery contacts and your device regularly.
- Avoid handling batteries with greasy or wet fingers.
- You should replace the battery if you notice distorted or weak sound, hear the low-battery warning or beep, or your device shuts off unexpectedly.
Choosing Based on Your Lifestyle
Your ideal hearing aid battery choice depends on how and where you use your hearing aids. Consider these factors:
- Streaming-intensive users may benefit from rechargeable batteries that manage power draw better over Bluetooth.
- Frequent travelers might prefer disposables, which can be bought almost anywhere.
- Dexterity challenges can make rechargeable systems (no fiddling with tabs daily) more appealing.
- Budget considerations: Rechargeable systems involve a higher upfront cost, while disposables incur ongoing purchases.
