WNC Audiology provides hearing aid batteries in Asheville, NC to ensure that your hearing devices always function at their best.
Hearing aid batteries provide the power your devices need to work. Without them, your hearing aids wouldn’t be able to amplify sound, stream music, connect to Bluetooth, or even run features like tinnitus relief programs. In short, batteries are what keep your hearing aids running day in and day out.
Today’s hearing aids can use either disposable batteries that you replace or rechargeable batteries that you simply charge overnight.
At WNC Audiology, our audiologists in Asheville, NC will help you choose the best option for your hearing aids and lifestyle.
Types of Hearing Aid Batteries
Disposable Zinc-Air Batteries
Disposable batteries, sometimes called “button batteries,” are the traditional option. They have a long shelf life and provide steady power for several days before needing replacement. To activate them, you remove a small sticky tab and let the battery sit for a few minutes before inserting it. They are color-coded by size for easy identification:
- Size 10 – Yellow
- Size 312 – Brown
- Size 13 – Orange
- Size 675 – Blue
Rechargeable Lithium-Ion Batteries
Many newer hearing aids now use built-in lithium-ion rechargeable batteries. These batteries typically provide a full day of power (18–30 hours, depending on usage). They’re especially helpful for people who have trouble handling small items due to vision or dexterity issues.
Rechargeable batteries are also an eco-friendly choice, since they eliminate the need to throw away hundreds of button batteries over time.
Silver-Zinc Rechargeable Batteries
Less common today, some older models still use silver-zinc rechargeable batteries. These can be removed and replaced as needed, though most manufacturers have shifted to lithium-ion for reliability and convenience.
Which Battery Should You Choose?
The right battery for you depends on your specific hearing aid model, your daily routine, and what feels easiest for you to manage. If you’re not sure, our audiologists at WNC Audiology can walk you through your options and recommend the best fit.
Tips for Making Batteries Last Longer
- After pulling the tab, wait 5 minutes before inserting to activate the battery fully.
- Store in a cool, dry place – never in the refrigerator.
- Open the battery door at night to preserve life and allow moisture to escape.
- Keep batteries clean and dry.
- Carry extras in their original case, not loose in a pocket or bag.
- Place them on the charger every night so they’re ready in the morning.
- Always use the charger that came with your hearing aids.
- Keep both hearing aids and charger away from water or excessive heat.
- If you’re not using your hearing aids for a while, turn them off to save battery life.
How to Know When to Change Your Battery
Your hearing aids may give you a warning when the battery is running low. This could be a beep, a flashing light, or even a spoken reminder. You may also notice sound becoming weak, distorted, or cutting in and out.
If your hearing aids suddenly stop working, a fresh battery is often the solution.
Troubleshooting Battery Problems
If your hearing aids aren’t working properly, try these quick checks:
- Is the battery the correct size?
- Is the battery door fully closed?
- Are the battery contacts clean and free of debris?
- Is the battery fresh or fully charged?
If you’ve checked all of these and still have issues, bring your devices to WNC Audiology for a professional checkup.
Frequently Asked Questions About Hearing Aid Batteries
Which type lasts longer?
Disposable batteries usually last 3–10 days, depending on size and usage. Rechargeable batteries last all day and are replaced only every few years.
Are rechargeable batteries better for the environment?
Yes. Rechargeables reduce waste because you’re not throwing away disposable batteries every week.
Can I switch my hearing aids from disposable to rechargeable?
It depends on your hearing aid model. Some devices can be upgraded, but many are designed for one battery type only. Ask one of our audiologists if you’re interested in switching.
Do cold temperatures affect batteries?
Yes, extreme cold can shorten battery life. Try to keep your hearing aids and spare batteries at room temperature whenever possible.
What should I do with old disposable batteries?
Used batteries should be recycled if possible. Many local stores and recycling centers in Asheville accept hearing aid batteries for safe disposal.
