Hearing Aid Batteries

Florida Medical Hearing provides hearing aid batteries in Sebring, FL and Lake Placid, FL.

Hearing aid batteries are what keep your devices running. Without them, your hearing aids wouldn’t be able to help you follow conversations, stream music, connect through Bluetooth, or reduce ringing in your ears (tinnitus). Choosing the right battery and caring for it properly can make a big difference in how well your hearing aids work every day. At Florida Medical Hearing, our hearing instrument specialist will guide you through your battery options and show you how to get the most out of them.

Types of Hearing Aid Batteries

Disposable Zinc-Air Batteries

These are the small, round “button” batteries that many hearing aids use. They’re lightweight, last several days, and have a long shelf life when stored correctly. To make them easy to identify, they are color-coded by size:

• Size 10 – Yellow
• Size 312 – Brown
• Size 13 – Orange
• Size 675 – Blue

Rechargeable Lithium-Ion Batteries

Most new hearing aids now come with built-in rechargeable batteries. With one overnight charge, they usually provide 18 to 30 hours of power. These batteries are a great choice if you don’t want to change batteries often or have trouble handling small ones. They’re also better for the environment since you don’t have to throw them away every few days.

Silver-Zinc Rechargeable Batteries

These are less common now, but some hearing aids still use them. They can be taken out and replaced when needed. Most companies now prefer lithium-ion batteries because they last longer and are easier to use.

Which Battery Is Best for You?

The right battery depends on your hearing aid model, your daily routine, and what feels easiest for you to use. If you’re unsure, our hearing instrument specialist at Florida Medical Hearing can help you choose the option that best fits your lifestyle.

Tips to Make Your Batteries Last Longer

For Disposable Batteries:

• Wait about 5 minutes after removing the sticker tab before putting them in.
• Store batteries in a cool, dry place (not in the fridge).
• Open the battery door at night to save power.
• Keep them clean and dry.
• Carry extras in their case

For Rechargeable Batteries:

• Charge your hearing aids every night.
• Always use the charger that comes with your devices.
• Keep both the charger and hearing aids dry.
• Turn them off if you won’t be using them for a while.

How to Know When It’s Time to Change a Battery

Most hearing aids give a warning when the battery is low. You might hear a beep, see a flashing light, or hear a spoken alert. You may also notice the sound getting weak, distorted, or cutting in and out. If your hearing aids suddenly stop working, it’s probably time to insert a fresh battery or recharge.

Troubleshooting Battery Problems

If your hearing aid isn’t working as it should, check the following:

• Is the battery the correct size?
• Is the battery door fully closed?
• Are the battery contacts clean and dry?
• Is the battery new or fully charged?

If you’ve tried these steps and the issue continues, bring your hearing aid to Florida Medical Hearing for a quick check.
