Learn All About Hearing Aid Batteries

Like more electronic components, hearing aid batteries are becoming more powerful, more technologically advanced, and even smaller in size, just like the hearing aids they power. As the landscape of hearing aids begins to change, so does the device requirements for power consumption and batteries size!

At Everything Hearing, we understand how complex it can be to navigate the onslaught of information about hearing aids, let alone their battery requirements. For this very reason, we have created a “one-stop shop” for everything you need to know about hearing aid batteries, sizes, lifespan, and brands!

The Sizes of Hearing Aid Batteries

Hearing aids come in a variety of different sizes, styles, and different power needs. Larger hearing aids require larger batteries, and smaller hearing aids require smaller batteries…you get the point! Additionally, hearing aids for people with severe or profound hearing loss typically require more power and, therefore, larger batteries.

There are five sizes of hearing aid batteries currently available on the market. From smallest to largest, they are designated by the numbers 5, 10, 312, 13, and 675. Due to the small size of the batteries, they are not often referred to by their size. Instead, a color-coding system is used. From the smallest to the largest, their coordinating colors are: red, yellow, brown, orange, and blue. A chart provided by Rayovac helps to illustrate this. Note that #5 is missing as it is very rarely used. (Photo chart courtesy of Rayovac.)

How Long Should Your Hearing Aid Batteries Last?

Batteries for hearing aids, on average, can last anywhere from 5 to 14 days based on usage and daily activity. How long each individually lasts is dependent upon the size of the battery and the amount of power needed by the hearing aid. Typically, smaller batteries have shorter battery life than larger ones.

If you are experiencing shortened battery life, there may be an issue with the hearing device or the battery itself. In this case, you should consult your user manual or contact us at Everything Hearing to ensure everything is working properly.

Types of Batteries for Hearing Aids


Nickel Metal Hydride

A nickel metal hydride (NiMH) battery is a type of rechargeable battery found in many rechargeable hearing devices. Widely used and having been around for longer, these batteries provide reliable power for the devices you need most!

Silver Zinc

Silver zinc batteries may be a newer development in the world of rechargeable power sources, but that by no means counts them out! For those who travel often or have other concerns regarding being able to charge their devices frequently, silver-zinc batteries can often be swapped out for a zinc-air battery, enabling you to continue your activity without compromising your hearing ability!


Trusted for use in a diverse array of devices, you may already be familiar with lithium-ion batteries! Packing a wallop of power while maintaining a small energy footprint, these rechargeable batteries can often deliver up to 24 hours of continuous use for your hearing devices!

Zinc Air

Zinc air button batteries are perhaps the traditional battery you think of when you think of hearing aids. These batteries are long-lasting and disposable, providing convenience when a place to recharge your devices may not be available!

Our Final Thoughts

The past ten years of hearing aid development have been characterized by significant technological progress. These advances have resulted in a massive increase in the level of power consumption. That means hearing aid batteries have become a very important consideration, not just for manufacturers but also for hearing care professionals and consumers.

The trend today for hearing aid wearers is the request for environmentally friendly and hassle-free battery solutions. At Everything Hearing, we meet these requests by offering rechargeable battery solutions and continuously recycling used battery components.
