Updated on March 16, 2021


Hearing aids can make a huge difference for individuals who have hearing difficulties. At the same time, they can also present some challenges that wearers will need to overcome. Hearing aid batteries are a vital component of these helpful appliances. Since hearing aids need a steady source of power to keep the wearer fully aware of their environment, the batteries play a critical role in the device.

Do you wear hearing aids, or have a loved one who wears them? Here is everything you need to know about the batteries to make life more meaningful for yourself or your loved one:

What Are the Different Types of Hearing Aid Batteries?

In the past, hearing aids had different types of batteries, including the old-fashioned mercury zinc button batteries. Modern hearing aid batteries come in two major types, disposable zinc-air button batteries and rechargeable lithium-ion batteries. While the former is used once and disposed of, the latter can be recharged and used for a longer time.

Furthermore, some hearing aids feature tiny batteries, which can be challenging to handle for many. For this reason, it’s advisable to choose hearing aids that you can conveniently charge while you are asleep. Are you tired of tiny hearing aid batteries?

How Long Do Hearing Aid Batteries Last?

Depending on the type of hearing aid, battery type and capacity, and how often the hearing aid is used, the batteries can last between three and 22 days. If you are using a rechargeable battery, you will have to charge it more often than you need to change a disposable battery.

How Safe Are Hearing Aid Batteries?

Hearing aid batteries are safe to use, but they can be a safety issue if you have little children or pets. Some loose-button batteries can look like small candy, so it’s important that you store your batteries out of reach of children and pets, and dispose of dead batteries properly.

How Do You Care for Hearing Aid Batteries?

If you want to optimize battery life of your hearing aids, be sure to turn them off when not in use. It is also important that you open the battery compartment when not in use to avoid corrosion. Consider removing the battery entirely if you are not going to use the hearing aid for an extended period.

How Should Hearing Aid Batteries Be Stored?

Proper storage of your hearing aid batteries is important for many reasons. Try to store your batteries at an optimal temperature of 10 to 25 degrees Celsius. Make sure the storage area doesn’t have any moisture problems. Don’t store your device in a refrigerator, as this will definitely damage it.


Taking care of your hearing aid batteries will help to prolong the overall life of your device. Take these tips into consideration to maintain your hearing aids in the years to come.
