When you’re relying on a hearing aid to stay connected, the last thing you want is to run out of power in the middle of a conversation. That’s why choosing the right power source matters-more than most people realize. For decades, disposable zinc-air batteries were the only option. Today, rechargeable hearing aids are taking over. But which one is right for hearing aid batteries or rechargeables? It’s not about which is better overall. It’s about what fits your life.
How Disposable Hearing Aid Batteries Work
Disposable hearing aid batteries are small, button-shaped cells powered by zinc-air chemistry. You pull off a tab, wait a minute for air to activate them, then pop them into your device. They come in four standard sizes: Size 10 (yellow), Size 312 (brown), Size 13 (orange), and Size 675 (blue). Each size matches a different hearing aid model based on power needs and size.These batteries last between 5 and 16 days, depending on how much you use your hearing aids. If you’re streaming music, watching TV, or using Bluetooth, they drain faster. A typical user might go through 10 to 20 batteries per year for both ears. That’s about $30 to $150 a year, depending on brand and where you buy them. A pack of six usually costs between $6 and $9.
The big upside? You can carry spares. Keep a small case with 6 to 12 batteries in your pocket, purse, or car. If one dies suddenly, you swap it out in seconds. No waiting. No charging dock needed. That’s why travelers, hikers, and people in areas with unreliable electricity still rely on them.
But there’s a catch. Changing these tiny batteries can be tough. If you have arthritis, shaky hands, or poor eyesight, pulling off the tab and inserting the battery correctly is a daily struggle. Many users report frustration with the sticky tab, the wrong orientation, or batteries falling out of their fingers. It’s not just inconvenient-it’s physically hard for a lot of older adults.
How Rechargeable Hearing Aids Work
Rechargeable hearing aids use built-in lithium-ion batteries, similar to those in smartphones. You take them out at night, place them in a charging case, and plug it in. In 3 to 6 hours, they’re good for another full day of use-usually 16 to 30 hours depending on usage. Some newer models, like the Phonak Audeo, give you 8 hours of power from just a 30-minute charge.These batteries last about 1 to 1.5 years before they start losing capacity. After 300 to 500 charges, they won’t hold a full charge anymore. At that point, you need to send them in for professional battery replacement-usually covered under warranty if your device is still under coverage.
The biggest win? Zero daily hassle. You don’t need to fumble with tiny batteries. Just drop them in the charger. Most users who switch say they forget they even have hearing aids because they’re so easy to manage. That’s why over 68% of users over 65 prefer rechargeables, according to Reddit’s r/Hearing community.
They’re also better for the environment. The average person using disposables throws away 100 to 200 batteries a year. Rechargeable users replace their battery just once every year or two. That’s thousands of pounds of battery waste kept out of landfills every year in the U.S. alone.
Pros and Cons: Side by Side
Here’s the real breakdown-what each system gives you, and what it costs you.
| Feature | Disposable Batteries | Rechargeable Hearing Aids |
|---|---|---|
| Power Duration | 5-16 days per battery | 16-30 hours per charge |
| Replacement Time | Seconds | 3-6 hours to charge |
| Initial Cost | Low ($0-$10 for starter pack) | High ($500-$3,500 for device + charger) |
| Long-Term Cost | $30-$150/year | $0-$100 every 1-2 years (battery replacement) |
| Dexterity Required | High | Low |
| Portability | Excellent (carry spares) | Good (need charger) |
| Environmental Impact | High (100+ batteries/year) | Low (1-2 replacements/year) |
| Compatibility | All styles, including CIC | BTE, RIC, ITE only-not CIC |
| Reliability | High (no electronics to fail) | Lower (charging circuit can malfunction) |
Rechargeables are more reliable in performance. Unlike disposable batteries, which slowly lose voltage as they drain (leading to quieter sound toward the end of their life), lithium-ion batteries keep steady power until they’re nearly empty. That means your hearing doesn’t fade mid-conversation.
But here’s the trade-off: rechargeables have more parts that can break. The charging dock, the internal battery, the contacts-all of them can fail. One user on Trustpilot said their charger stopped working after 14 months. Replacing it cost $120 out-of-pocket because the warranty had expired. With disposables, if the hearing aid stops working, it’s almost always the battery. You swap it. Done.
Who Should Stick With Disposable Batteries
You’re still better off with disposables if:
- You use completely-in-canal (CIC) hearing aids-rechargeables can’t fit inside them.
- You travel often without reliable access to outlets, like backpackers or cruise travelers.
- You live in a region with frequent power outages.
- You’re not ready to invest in a new hearing aid system.
- You’ve had success with disposables and don’t want to change a system that works.
Many older adults who’ve used disposables for years don’t see a reason to switch. And that’s fine. If you can handle the batteries, there’s no need to force a change.
Who Should Switch to Rechargeable
Rechargeables are the clear winner if:
- You have arthritis, tremors, or trouble gripping small objects.
- You hate running out of batteries unexpectedly.
- You’re tired of buying packs of batteries every few months.
- You want to reduce your environmental footprint.
- You’re willing to charge your devices nightly.
For people over 70, the shift to rechargeables isn’t just about convenience-it’s about independence. A 2023 Arthritis Foundation survey found that 35% of hearing aid users over 70 struggle with fine motor tasks. For them, rechargeables aren’t a luxury. They’re a necessity.
And the numbers show it. In 2023, 72% of new hearing aids sold in the U.S. were rechargeable. That’s up from just 28% in 2018. Technology is improving fast. New models like Starkey’s wireless charging system eliminate the need to line up the hearing aids perfectly in the dock. Widex’s new temperature-resistant batteries work in freezing cold or hot climates. These aren’t just incremental upgrades-they’re game-changers.
What You Need to Know Before You Switch
Switching from disposables to rechargeables isn’t as simple as buying a new device. You need to adjust your routine.
Successful users follow one rule: charge every night. Ninety-two percent of people who stick with rechargeables do it without fail. They take their hearing aids out before bed, put them in the charger, and plug it in. That’s it. No thinking. No reminders. It becomes part of brushing your teeth.
If you forget to charge, you’re stuck. Unlike disposables, you can’t grab a spare. That’s why it’s smart to keep one extra set of disposable batteries on hand-even if you mostly use rechargeables. Just in case.
Also, don’t assume all rechargeable hearing aids are the same. Battery life varies by brand and model. Some last 24 hours. Others only 16. Check the specs. Ask your audiologist. Don’t just go by price.
What’s Next for Hearing Aid Power?
The future is hybrid. Researchers at Stanford are testing solid-state batteries that could give hearing aids 48 hours of power on a single charge. Other companies are working on micro-rechargeable batteries you can swap like disposables-but recharge them at home. Imagine a tiny battery you pop in and out, but it lasts 5 days and recharges in 2 hours. That’s the next step.
By 2027, experts predict 85% of new hearing aids will be rechargeable. By 2030, disposables might be rare outside of CIC models or emergency backups.
But for now, both options have their place. The best choice isn’t the newest tech. It’s the one that fits your body, your habits, and your life.
Can I use rechargeable batteries in my current hearing aids?
No. Rechargeable hearing aids have built-in lithium-ion batteries that are not replaceable by users. You can’t just pop a rechargeable battery into a device designed for disposables. If you want rechargeable power, you need to buy a new hearing aid model that supports it.
How long do rechargeable hearing aid batteries last before needing replacement?
Most rechargeable hearing aid batteries last between 1 and 1.5 years, or about 300 to 500 full charge cycles. After that, they hold less than 80% of their original capacity. At that point, you’ll notice shorter battery life, even after a full charge. Replacement requires a professional service visit and is often covered under warranty if your device is still within the coverage period.
Are disposable hearing aid batteries bad for the environment?
Yes. While modern disposable hearing aid batteries are mercury-free, they still contain zinc and manganese, which can leach into soil and water if thrown in regular trash. In the U.S., 38 states require them to be recycled separately. The average user discards 100-200 per year. Rechargeables reduce this waste by 95% or more.
What should I do if my rechargeable hearing aid stops holding a charge?
First, check the charging dock and contacts for dirt or corrosion. Clean them gently with a dry cloth. If that doesn’t help, try a different power outlet. If the problem continues, contact your hearing care provider. Most manufacturers will replace the battery under warranty if your device is less than 2 years old. After that, replacement costs typically range from $80 to $150.
Do rechargeable hearing aids work during power outages?
They only work if they’re already charged. If the power goes out and your hearing aids are dead, you won’t be able to recharge them until electricity returns. That’s why it’s smart to keep a few disposable batteries on hand as a backup. Even if you use rechargeables 95% of the time, having a spare set can save you from being left without hearing during an emergency.
Can I travel internationally with rechargeable hearing aids?
Yes, but you’ll need a universal travel charger that works with different plug types. Most modern charging cases support 100-240 volts, so they work in Europe, Asia, Australia, and North America. But you’ll still need the right plug adapter. And if you’re going somewhere without reliable power-like a remote cabin or a long flight-you should bring spare disposable batteries as a backup.
Final Thoughts
There’s no one-size-fits-all answer. Rechargeables are easier, greener, and smarter for most people. But disposables still have their place-for those with CIC devices, frequent travelers, or anyone who just prefers the simplicity of a swap-and-go system.
The key is to match your power source to your lifestyle-not the other way around. If you’re considering a switch, talk to your audiologist. Ask about trial periods. Some clinics let you test rechargeable models for a week. See how it feels. See if you forget to charge. See if your hands thank you.
Technology is moving fast. But your hearing shouldn’t be an afterthought. Choose what lets you hear clearly, comfortably, and without stress.

They're tracking you through your hearing aids. The rechargeable ones have GPS chips hidden in the charging case. They know when you're home, when you're out, and who you talk to. Don't be fooled by the 'convenience'.

I mean honestly I just use whatever my audiologist gave me and I forget about it until it dies and then I get annoyed and then I buy more batteries or charge it and honestly I don't even think about it anymore like why do we even have to make this a thing it's just a device that helps me hear why does it have to be so complicated

I love how this post breaks it down so clearly. My dad switched to rechargeables last year after struggling with tiny batteries for 15 years. He said it changed his life-he finally feels independent again. And honestly, the environmental angle is huge. Every time I see someone throw out a pack of those tiny batteries, I cringe. We can do better.
