When to Change Hearing Aid Batteries

Batteries are the lifeblood of your hearing aids. Without them providing the power you need, your hearing aids won’t function and will affect your hearing care. Knowing when to change them will ensure that you are able to hear clearly at all times. This way you never get caught in a difficult situation.

It’s important to know the different types of hearing aid batteries to fully understand when hearing aids need to be given new ones. While standard hearing aid batteries can last between three and 22 days, there are factors that can affect these numbers.

The model of hearing aids you wear and how often you use them can certainly affect when you need to change your batteries. For tips on this, make sure to read our article on how to choose the right hearing aid. Additionally, your battery type and its capacity will make a difference in when your batteries need to be changed.

How to make hearing aid batteries last longer

Did you know that shortly after you peel off the plastic tab, your battery will start to lose its total charge? Fortunately, there are some effective tips you can implement that will help you get the most life from your batteries.

  • Don’t peel off the protective tab unless you are ready to use your hearing aid battery within five minutes. Even the best long-lasting hearing aid batteries will begin to drain moments after the tab is removed. To get the most from your hearing care, leave each battery in its packaging until it is ready to be used.
  • If you aren’t wearing your hearing aids, it is important to keep them turned off. No sense in draining the batteries when they’re not being used. Alternatively, you can simply open the battery door, as this will disengage the battery and turn off your device.

*Try getting into the habit of leaving open the battery door each night before bed. This will allow your hearing aids to air out while reducing the risk of corrosion.

  • Temperature can also have an effect on your battery life. You should make sure that you never leave your hearing aids in a hot car, for example. Conversely, you should only store your batteries somewhere that isn’t too cold or hot.
  • If you know that you aren’t going to be wearing your hearing aids for several days at a time, it’s better to completely remove each battery until you are ready to wear them again. This will prolong the life of your batteries and prevent unnecessary discharge.

Should I change both hearing aid batteries at the same time?

Unlike traditional battery types, hearing aid batteries don’t get weaker before they stop working. Once they are used up, they will simply cease to provide power to your hearing aids. As such, it is not necessary to change the batteries in each device at the same time.

If you are on a tight budget and are trying to do all that you can to prolong the life of your batteries, only change the battery that has stopped working.

If you want to be sure that you never experience hearing loss due to your hearing aid battery dying, try setting aside a day each week for changing them. For example, you could switch out the left ear battery every Sunday. While the right ear battery is changed every Wednesday.

Having a set schedule in place will ensure that you always have better hearing. No more getting caught in a situation that leaves you unable to hear sound clearly.

Where can I get replacement batteries?

Any hearing aid center should either stock or be able to order the batteries you need for your hearing aids. Additionally, you can pick up hearing aid batteries at most drug stores and retail stores.

If, however, you don’t want to risk going out in public, popular online marketplaces carry an extensive line of hearing aid batteries. Many of them will ship your order out to you in just a few days, ensuring that you aren’t without the hearing care you need.

If you want to get the most bang for your buck, buying online is definitely the way to go. Online stores give you the option to buy your hearing aid batteries in bulk, allowing you to receive a large number of them at an affordable price.

What is the 5-Minute Rule for hearing aid batteries?

The “Five-Minute Rule” is an incredible find that was discovered by an eighth-grader in Rochester, Minnesota. This simple yet effective trick will not only extend the life of your batteries, but it will also save you money in the long run by reducing your need to change them as frequently.

Before inserting a battery into your hearing device, wait five minutes after taking the battery out of its packaging and removing its plastic tab. When five minutes have passed, place the battery in your device. In doing so, each battery can last as much as three days longer than it normally would.

The student, who also happens to wear a hearing aid for improving sound, came to this conclusion after studying and testing the effects that oxygen has on batteries. Whenever you remove the protective tab, oxygen begins to mix with the battery’s zinc oxide.

When this is allowed to occur for five minutes, it gives the battery a boost in its effectiveness and lets you get more use out of it. So effective is the Five-Minute Rule that it has since won the student multiple awards and recognition. If you want to get the most out of your hearing aid battery and save money, this trick is sure to serve you well.


Knowing when to change out your hearing aid’s battery will ensure that you get the best performance in your hearing care. It is also important to know how to care for your batteries. Whether you use an over the counter hearing aid or a traditional prescription hearing aid, with the proper handling and use, you can look forward to each battery providing you with long-lasting service.
