Batteries for Hearing Aids: Lithium vs Zinc Air Which Lasts Longer

If you’re looking for batteries for hearing aids, you’re likely wondering: Which type lasts longer, lithium or zinc-air? The short answer is that lithium batteries usually last longer than zinc-air batteries, especially in high-drain devices. But there’s more to consider than just battery life.

In this guide, we’ll walk you through everything you need to know about these two popular types of hearing aid batteries. From how they work to real-world performance, we’ve got you covered.

Part 1. What are batteries for hearing aids?

Batteries for hearing aids are small power sources that keep your device working all day, and power features like noise control, wireless streaming, and Bluetooth.

There are two main types:

• Zinc air batteries: These are disposable. You throw them away when used up.
• Lithium-ion batteries: These are rechargeable. You use them again and again.

Each type works differently and fits different lifestyles.

Part 2. How zinc air batteries for hearing aids work?

Zinc-air batteries are the older type. They use oxygen from the air to create power. When you remove the small tab on the battery, air goes in and starts the battery.

Main features:

• Used in most older and budget hearing aids
• Come in four sizes: 10, 13, 312, and 675
• Start working when the tab is removed
• Do not recharge — you throw them away
• Cost less at the start

These batteries are easy to find in stores. But they don’t last very long.

Part 3. How do lithium-ion batteries for hearing aids work?

Lithium-ion batteries are built into your hearing aids. You do not take them out. Instead, you place your hearing aids into a charger. Most people do this at night, like charging a phone.

Main features:

• Used in modern digital hearing aids
• Rechargeable — no need to change batteries often
• Great for streaming, Bluetooth, and smart features
• Better for the environment
• Safer and sealed inside the device

These batteries are more expensive at first, but often save money in the long run.

Part 4. Which batteries for hearing aids last longer: lithium or zinc-air?

Here is a real-world performance comparison. The numbers may vary depending on how much you use your device and what features are turned on.

Quick tip: If you want fewer interruptions and daily reliability, lithium-ion batteries are the better choice.

Part 5. Are lithium batteries for hearing aids better for modern devices?

Yes. Lithium-ion batteries work best with today’s digital hearing aids. These devices often include:

• Bluetooth audio
• Mobile app control
• Smart noise filters
• Automatic sound changes

All these features use more power. Zinc-air batteries may not keep up, especially with streaming. Lithium-ion batteries give you longer daily use and stronger performance.

Why lithium-ion is better for modern hearing aids:

• Handles more power use
• Charges overnight for all-day use
• No need to carry spares
• Safer with no exposed battery parts

Part 6. Pros and cons of zinc-air batteries for hearing aids

Pros:

• Cheap to buy at first
• Easy to find in stores
• No charger needed
• Lightweight and small

Cons:

• Runs out fast (every few days)
• You must change them often
• Not suitable for Bluetooth streaming
• Bad for the environment
• It can be hard to handle if you have shaky hands

Zinc-air batteries are okay for users with simple needs and basic hearing aids.

Part 7. Pros and cons of lithium-ion batteries for hearing aids

Pros:

• Rechargeable — no need for weekly changes
• Lasts all day on one charge
• Great for streaming and smart features
• Less battery waste
• Safer — sealed inside the hearing aid

Cons:

• Costs more at first
• Needs charging every night
• Only works with specific devices

Lithium-ion batteries are best for users who want convenience and more features.

Part 8. How to choose the right batteries for hearing aids?

Here are a few things to think about:

• Device type: Some hearing aids only use zinc-air batteries. Others are made for lithium-ion.
• Your habits: If you stream audio or talk on the phone a lot, lithium-ion is better.
• Budget: Zinc air is cheaper at the start. But lithium saves money over time.
• Convenience: If you hate changing batteries, go with lithium.
• The environment: Lithium-ion is more eco-friendly. Less waste.

The best choice depends on your lifestyle and hearing aid type. Check your hearing aid manual or talk to your audiologist.

Part 9. How long do batteries for hearing aids last in daily use?

Zinc air battery life by size:

• Size 10: 3 to 5 days
• Size 312: 5 to 7 days
• Size 13: 6 to 10 days
• Size 675: 9 to 15 days

Lithium-ion battery life:

• 16 to 30 hours per charge
• Recharge daily
• Whole battery lifespan: 3 to 5 years

If you use Bluetooth or streaming, both types will run out faster. But lithium-ion still performs better under heavy use.

Part 10. How do weather and storage affect batteries for hearing aids?

Battery life also depends on how and where you store them.

Zinc air:

• Do not store in wet or humid places
• Keep in dry, cool areas
• Let the battery sit for 1–2 minutes after removing the tab

Lithium-ion:

• Do not expose to high heat or cold
• Keep away from direct sunlight
• Store at room temperature
• Keep charging contacts clean

Good storage helps your batteries last longer and work better.

Part 11. FAQs about batteries for hearing aids

Which hearing aid battery lasts the longest?

Lithium-ion batteries last longer overall. One charge lasts all day, and the battery itself works for years.

Are rechargeable hearing aid batteries worth the price?

Yes. They cost more at first, but save money over time. They are also easier and greener.

Can I switch from zinc air to lithium-ion?

Only if your hearing aid supports it, not all devices can change. Ask your hearing specialist.

How can I make zinc-air batteries last longer?

After removing the tab, let them “breathe” for 1 to 2 minutes. Store them in a dry place. Turn off your hearing aids when not in use.

Are lithium-ion batteries safe?

Yes. They are sealed inside the hearing aid. Just avoid water and heat.

Part 12. Final thoughts on batteries for hearing aids

When choosing batteries for hearing aids, think about your lifestyle, device, and budget. If you use advanced features like streaming, or if you want fewer battery changes, lithium-ion is the better choice. It is more modern, lasts longer, and is better for the planet.

But if you use a basic hearing aid or prefer lower upfront costs, zinc-air batteries are still a good option. They are easy to find and work well for simpler needs.
