The Trick to Making Hearing Aid Batteries Last Longer

The Trick to Making Hearing Aid Batteries Last Longer

When you first wear the hearing aids picked out with the help of your audiologist, they can have a truly profound and transformative effect on your life. The immediate difference they can make to your hearing and the quality of life improvements you discover as you continue to wear them can be nothing short of life-changing.

However, nothing lasts forever, and your hearing aid batteries running out will become a recurring issue. For some people, they run out much faster than they need to, however. Here, we’re going to look at what you can do to help them last longer.

How long are hearing aid batteries supposed to last?

The answer to this question varies, but it’s usually between three and 22 days. Larger batteries last longer, and the longer you use your device throughout the day, the faster they will drain. It also depends on what technology and features are used in the device, but the factor that will impact their longevity is how well you take care of them. With that in mind, here are a few tips for just that. 

Don’t let your batteries sit in storage for too long

Batteries slowly lose their charge, even when they’re not being used. As such, if they’re in storage, they will still run out of power eventually. For that reason, use the oldest batteries you have available first, so you get as much power out of them as possible rather than letting them dwindle.

Give them time to activate

When you first open a pack of batteries, you have to pull a tab off of them. When you do that, you should set them out in a cool, dry place for three to five minutes before putting them in your device. The air activates the materials that the batteries are made of, which means they can supply power more effectively.

Don’t remove the tabs on the batteries before you’re ready to use them

The same process by which the air “activates” the battery and makes it ready to use also means that the battery will start to drain more effectively. It needs to do this in order to power the hearing aid, but it also means that leaving it around out of use for too long could result in it having a shorter battery life. So, remove the tab three to five minutes before putting the battery in the hearing aid, but only remove it when you’re definitely going to use it.

Keep them in a suitable place

Batteries can be affected by the environment. Places that are too hot, too cold, or too humid can cause them to lose their charge faster, or even leak, which can do damage to your device. Keep them in a dry, room temperature area when not using them, preferably in a battery case, and never keep them in the bathroom or fridge.

Wash your hands before handling batteries

Whether you’re taking them out, installing them, or switching them around, you should wash and dry your hands before you handle any batteries. Grease and dirt on your hands can transfer to the batteries, which can not only damage them but can also damage your hearing aid.

Don’t close the battery component when not using your hearing aids

Turn off your hearing aid whenever you’re not using it and leave it somewhere safe and dry (preferably a case made specifically for storing the device). Take out the battery and leave the battery door open so that excess moisture can escape from the storage compartment. Letting the moisture escape can preserve battery life and stop it from corroding.

Try a hearing aid dehumidifier

As mentioned, moisture can be terrible for your hearing aid batteries. A hearing aid dehumidifier can help drain the moisture from both the battery and the device itself, which, in turn, will allow the battery to be used more efficiently. A dehumidifier makes a great place to store your hearing aid when you’re not using it, so ask your audiologist which one they would recommend.

Check with your audiologist

If you’re following every battery care trick in the book, there could be some malfunction or issue with the hearing aid that is draining them quicker than it should be. Your audiologist can help you diagnose and fix a whole host of issues with hearing aids and hearing aid batteries.
