7 tips to make your hearing aid batteries last

If you’re like most hearing aid users, chances are you probably wouldn’t mind a little extra time between having to change your batteries. Here, we’ve compiled some tips and tricks that can help you increase the longevity of a charge. 

But before diving into what you can do, here’s a breakdown of what plays into your hearing aid battery’s lifespan. The staff at AARP have explained that hearing aid battery life comes down to a few basic factors:

  • The type of hearing aid you use
  • How you use your hearing aid
  • The kind of hearing aid batteries you purchase
  • The assistive listening devices you may use with your hearing aids
  • Specific features of your hearing aids (i.e. wireless capabilities)

It’s also important to consider that different hearing aids require different types of batteries. For instance, a hearing aid battery for large hearing aids, or non-wireless hearing aids, may last two weeks, while batteries for smaller hearing aids, or wireless hearing aids, may only last two or three days.
 

How to extend the life of your hearing aid batteries

It is important to be cognizant of the signs that your battery is about to give out. Those signs could include weak output, distortion, increased the tendency of hearing aid feedback, and static or fluttering sounds (Better Hearing Institute). Whether you’re wearing a receiver-in-canal or behind-the-ear model, or something else entirely, try out these 7 tips to squeeze some extra juice from those precious batteries!

1. Store hearing aid batteries properly

Taking care of batteries also requires proper storage. Extreme temperatures and moisture may shorten the life of hearing aid batteries, so be sure to keep them in a cool, dry place. While you may have heard that storing hearing aid batteries in the refrigerator extends their life, history and research shows that this is false.

While this may have been a common practice years ago, most hearing aid batteries today rely on a “zinc-air type,” which means a battery charge does not begin until a pull-tab is removed from each hearing aid battery. 

2. Don’t open until ready to use

As mentioned above, hearing aid batteries come in sealed packs with plastic tabs placed on the back of each battery. Once the tab is removed, the hearing aid batteries come into contact with air, which ultimately activates the battery to begin using energy.

To extend the life of your hearing aid conserve battery power, leave the plastic tabs inserted until you are ready to place the batteries in your hearing aids and begin using them.

3. Handle with clean hands

Wash your hands before handling your hearing aid batteries. Oil and grease from your hands, as well as dirt and grime, can not only cause issues with your hearing aid battery, but can cause damage to the hearing aid itself. 

4. Disengage the battery at night

To prolong the life of your hearing aid batteries, open the battery door at night. Opening the battery door allows excess moisture to escape, minimizing battery drainage and preventing battery corrosion. Just be sure to store your hearing aids in a safe place at night, away from pets or liquids. 

5. Develop a replacement cycle

Knowing when the batteries for your hearing aids will give out can eliminate a large source of stress that may accompany using hearing aids. The easiest way to do this is by marking the calendar each time a hearing aid battery goes dead.

For example, you could keep a schedule of battery changes and mark RB for the right hearing aid battery and LB for the left hearing aid battery—this will make it easy to remember and keep track of. After a few battery cycles, you will be able to anticipate when your batteries are likely to run out, so you know when to have a fresh pair ready. 

6. Try out different brands

When it comes to choosing batteries for hearing aids, it pays to follow mom’s advice: shop around! Take the time to research and evaluate different hearing aid batteries to see which brand works the best with your set of hearing aids.

A word of caution: be sure to check the expiration date before purchasing batteries for hearing aids. Batteries eventually deteriorate, and even unused batteries will eventually lose their energy. Check the sell-by date, and don’t buy batteries you aren’t going to use within the next year.

If hearing aid batteries are deeply discounted, it may be because they are about to expire, so take the time to investigate the expiration date before your final purchase.

7. Try rechargeable batteries

If you don’t want to bother trying to figure out what batteries work best with your hearing aid devices, try rechargeable batteries instead! Just be sure your hearing aids will still work properly if using this type of battery technology.

Find out if your hearing aid device is compatible with rechargeable batteries by contacting your local Connect Hearing center.
