Do you feel like your hearing aid batteries won’t keep a charge as long as they should? The reasons for this can be sometimes unexpected. How long should hearing aid batteries keep a charge? Anywhere from 3 to 7 days is typical. That’s a very wide range. Actually, it’s so wide that it probably can’t help you predict what should be taking place with your hearing aid. You could be on day 4 at the grocery store when unexpectedly, things get quiet and you can’t hear the cashier. Or it’s day 5 and you’re having a call with friends when all of a sudden you find yourself feeling very alone because you can no longer hear the conversation. Sometimes the batteries don’t even make that 3 day mark. Like when you’re watching TV on day 2 and suddenly you can’t hear the show your watching. It isn’t just inconvenient. You just can’t tell how much battery power your hearing aids have left and it’s making you miss out on life. If your hearing aid batteries are draining too quickly, there are several likely causes.

Moisture Can Deplete a Battery

Did you realize that humans are one of the few species that release moisture through their skin? We do it to cool down. It’s the body’s way of ridding the blood of toxins and sodium. You may also live in a climate that’s moist and humid. The air vent in your hearing aid can become clogged by this extra moisture and it will be less effective. It can even deplete the battery directly by interacting with the chemicals which create electricity. You can prevent moisture-related battery drainage with these steps:

  • A dehumidifier for your hearing aid is helpful
  • if your storing them for a few days or more, remove the batteries
  • Don’t keep your hearing aids in the bathroom, kitchen or other damp environments
  • When you store your hearing aids, open the battery door

Advanced Hearing Aid Features Can Drain Batteries

You get a much better hearing aid now than you did even ten years ago. But if you’re not keeping your eye on them, these advanced functions can cause faster battery drain. You can still use your favorite features. But remember, you will need to change the battery sooner if you are streaming music from your phone for hours. Your battery can be drained by any of the advanced features, like multichannel, Bluetooth, noise cancellation, and tinnitus relief.

Altitude Changes Can Affect Batteries Too

Your batteries can be sapped out if you go from low to high altitudes specifically if they are already low on juice. Bring some extra batteries if you are going on a plane or high up into the mountains.

Maybe The Batteries Aren’t Really Low

Some models will give you a warning when the battery begins to get too low. These alerts are, under normal circumstances, a “heads up”. They’re not telling you the battery is dead. Additionally, the charge can at times dip briefly due to environmental or altitude changes and that can trigger a false low battery warning. In order to end the alarm, remove the batteries, and then put them back in. You may be able to get a few more hours or even days out of that battery.

Handling Batteries Improperly

You should never remove the little tab from the battery before you’re ready to use it. Make sure you wash your hands before touching your hearing aids or batteries to avoid getting hand oil or dirt on them. Hearing aid batteries should never be frozen. This trick may extend the life of some types of battery but it doesn’t work with hearing aid batteries. Hearing aid batteries might lose battery power more quickly if you make these basic handling mistakes.

Getting a Year’s Supply of Batteries Isn’t a Very Good Idea

If you can afford to do it, purchasing in bulk can be a smart plan. But as you get toward the end of the pack, the last several batteries probably won’t last as long. Try to stick with a 6-month supply or less unless you’re fine with wasting a few.

Shopping For Hearing Aid Batteries Online

Buying from the web can be a good thing. You can get some great deals. But some less scrupulous people will sell batteries online that are very close to the expiration date. Or even worse, it has already passed. So buyer beware.
Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have a date they will expire. If you were going to buy milk, you would look at the expiration date. You should use the same amount of caution with batteries. If you want to get the most out of your pack, make sure the date is well in the future. It’s probably a smart idea to message the vendor if you don’t see an expiration date or better yet, come see us for your battery needs. Be sure you know and trust the seller.

Now You Can Get Rechargeable Hearing Aids

There are several reasons that hearing batteries could drain rapidly. But you can get more power from your batteries by taking some precautions. If you’re in the market for a new pair of hearing aids, you might consider a rechargeable model. If you charge them while you sleep, you get a full day of hearing the next day. And you only need to replace them every few years.
