We are fortunate to be in a time where technology is allowing us to improve our health and one area that we are seeing huge strides in is hearing aids. Hearing aids are getting more advanced as time goes on, and you get more power and new features in the hearing aids of today than ever before. These hearing aids are still evolving, and one of the main focuses for repair is in hearing aid batteries.

Currently, hearing aid batteries can last between three and ten days, depending on the usage, but it's essential that we understand why the life of your hearing aid batteries are so unpredictable. Your audiologist can take you through how to look after your hearing aid batteries, when to swap them out and how to fix a problem when it arises, but you do need to consider how you can look after your hearing aids yourself at home. So, let's take a look at some of the ways that you can maximize the life of your hearing aid batteries and make sure that they are working correctly at all times.

  1. Firstly, you need to think about how you can let the battery breathe. Sometimes, condensation can get into your hearing aid and make the battery short, so instead of worrying about that happening, you should allow the battery to breathe. Pop it out of the tab and let the battery sit before you install it into your hearing aid. The air can reach the inside of the battery and activate it properly.
  2. Before you change out your batteries for a new one, your audiologist will advise you to wash your hands. Your hands can become dirty and greasy throughout the day, and this can damage the battery, which can further damage your hearing aids.
  3. Leave the door to the battery open at night time. You don't wear your hearing aids to bed, so it stands to reason that this is the perfect time to minimize battery drain. Leave the battery compartment door open and let moisture escape.
  4. Did you know that hearing aid batteries have an expiration date? The further out the batteries are from their expiration date, the fresher they are, the better to use. Your audiologist should be able to show you where you can find the expiration date for your batteries.
  5. If you don't plan to use your batteries for an extended length of time, think about removing the battery from the hearing aid entirely. You can avoid the battery corroding entirely and release any trapped moisture from the space, too.
  6. Your audiologist should explain this to you, but you should always keep your batteries for your hearing aid in a cool, dry place away from extreme temperatures and out of sunlight.
  7. Did you know that there are rechargeable hearing aids out there? You can use rechargeable batteries so that you can charge the battery at night. This way, you can get a full day of use out of them. You don't have to change the batteries as often, and rechargeable batteries should be replaced every year instead of sooner than that. Your audiologist can explain to you all you need to know about the new hearing aid technology out there so you can make the best decision for you.
  8. There are hearing aid dehumidifiers on the market that can be a powerful way to absorb moisture from the hearing aid itself, and this can improve the efficiency of the battery. Also, a dehumidifier is the perfect place to store your hearing aids when not in use!
  9. When you come to change your batteries, the oldest pack of batteries that you have should be used first. This way, you get the most life out of them, and when they do run down, you're going to have newer ones waiting to use.
  10. Keeping your hearing aids clean is essential, as any debris or dust can get inside them and ruin the battery. Your hearing aid batteries need to be used in a way that keeps them preserved for as long as possible.
  11. Never, ever keep your batteries for your hearing aids in the refrigerator. Some people may tell you it's a good idea for keeping your batteries fresh, but it comes under the same rule about extreme temperatures.

Hearing aid batteries need to be well cared for at all times if you hope to be able to continue to use your hearing aids. To learn more about your hearing aid batteries, contact Pacific Audiology Clinic at 503-719-4208.
