What You Need to Know About Hearing Aid Batteries

Hearing aids bring incredible clarity to everyday life, and one key element powering these transformative devices is the battery. Hearing aid batteries deserve special attention, as they are vital to a device’s success and longevity. If you have some questions about hearing aid batteries, we’ve certainly got the answers.

While some hearing aids still use traditional disposable batteries, many of today’s models feature rechargeable batteries for an extra layer of convenience. Whether your hearing aid is rechargeable or powered by disposable batteries, this guide sheds light on all the information you need to know to ensure your device is ready to perform its best when you need it.

Disposable Batteries – How They Work & How Long They Last

Before rechargeable options emerged, disposable batteries were the primary power source for hearing aids. These batteries were mainly zinc-air batteries because of their voltage consistency. Zinc-air batteries feature tiny perforations on the surface that allow air to flow inside, which results in a chemical reaction with the zinc within the battery. This chemical reaction causes zinc oxide to form, ultimately producing a steady stream of energy. Needless to say, science is pretty incredible.

Depending on the battery's size, lifespan varies anywhere between 3 to 20 days. Your hearing aid's technology and how long you use it will also impact each battery’s life. Disposable hearing aid batteries are packaged with a protective seal to prevent them from prematurely discharging power, so it’s important to remove the seal only when you’re ready to use your battery.

Which Hearing Aid Battery Size Do I Need?

Hearing aid batteries are available in four primary sizes: 10, 13, 312, and 675, each color-coded for easy selection. Size 10 is marked with yellow, 13 with orange, 312 with brown, and 675 with blue. This simple color system helps you easily find the right fit for your hearing device. Different sizes are meant for specific hearing aid models – each with different power levels and lifespans.

If you’re unsure what battery size you need for your device, check your hearing aid's packaging or manual.

Size 10 (Yellow) Batteries

Size 10 batteries are typically used for completely-in-canal (CIC) and some in-the-ear (ITE) hearing aids. Although smaller and less powerful, size 10 batteries effectively power discreet devices, making them a smart choice for those who value subtlety in their hearing aid.

Size 13 (Orange) Batteries

Size 13 batteries are ideal for behind-the-ear (BTE) and some in-the-ear (ITE) hearing aids. They offer a strong mix of size and power. This versatility suits many hearing aid models, ensuring optimal performance and longevity.

Size 312 (Brown) Batteries

Size 312 batteries are a common choice for in-the-ear (ITE) and some behind-the-ear (BTE) hearing aids. They provide a balance of size and power, making them convenient and reliable for daily use.

Size 675 (Blue) Batteries

Size 675 batteries are the largest choice for behind-the-ear (BTE) hearing aids, providing exceptional power. They are perfect for devices with advanced features that need more energy. Size 675 batteries support robust performance, especially for those with severe hearing loss.

How to Insert a Disposable Hearing Aid Battery

To insert a hearing aid battery, first remove the adhesive seal and let it sit for about two minutes. This allows the battery to activate. Align the battery with the positive (+) and negative (-) markings in your hearing aid's battery compartment.

Make sure the battery compartment closes completely. If it resists, check its positioning. If your device doesn’t work after inserting the battery, inspect the compartment for dirt or debris. Many manufacturers provide a magnetic tool to assist with battery placement, making the process simple.

Hearing Aid Battery Storage

Store your hearing aid batteries at room temperature, ideally between 50°F and 77°F. Avoid extreme conditions like direct sunlight, which helps maintain battery life. Never place batteries in the refrigerator and keep them safely out of the reach of children. Once they are depleted, remove them to prevent damage, such as leaks or swelling, that can affect your hearing aid's functionality.

Hearing Aid Battery Disposal

Used hearing aid batteries need proper disposal to protect both your device and the environment. If you’re using standard disposable batteries, don’t just toss them in the trash when they run out. Take them to a local audiology center or a designated collection point for safe handling. Responsible disposal helps prevent environmental contamination and supports a greener community.

The Revolutionary Rechargeable Hearing Aid Battery

Rechargeable batteries are now a key feature in modern hearing aids, offering a sustainable and hassle-free solution for many users. Rechargeable batteries reduce the need for constant replacements and help minimize environmental waste. Instead of frequently swapping out disposable batteries, recharging your devices overnight provides ease and reliability.

Simply set your hearing aids in their charging station before sleep and wake up ready for a full day of clear hearing. Most hearing aid models now support these rechargeable options. Consult your audiologist to learn more about rechargeable hearing aids and if they align with your lifestyle and hearing needs.
