Does it seem like your hearing aid batteries lose their charge too quickly? The reasons for this are sometimes unexpected.How long should hearing aid batteries last? Between 3 to 7 days is standard. That’s a really wide range. So wide, actually, that it’s unpredictable and leaves you in a challenging predicament. Things might suddenly go quiet when you’re trying to hear the cashier at the supermarket after 4 days of battery power. Or it’s day 5 and you’re having a call with friends when unexpectedly 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 that’s on. It’s more than a little inconvenient. You’re missing out on life because you don’t know how much battery power you have left in your hearing aids. If your hearing aid batteries are draining too rapidly, there are several likely causes.

Moisture Can Deplete a Battery

There aren’t very many species that produce moisture through their skin but humans do. It’s a cooling mechanism. We do it to clear out excess sodium or toxins in the blood. You might also live in a climate that is moist and humid. The air vent in your hearing aid can get clogged by this added moisture and it will be less effective. It can even deplete the battery directly by interacting with the chemicals which generate electricity. Here are some steps you can take to prevent moisture-caused battery drain:

  • When you store your hearing aids, open the battery door
  • Moist conditions, like the kitchen or bathroom aren’t a good place to keep your hearing aids
  • A dehumidifier for your hearing aid is recommended
  • Don’t leave the batteries in if you’re storing them for a number of days

Advanced Hearing Aid Features Can Deplete Batteries

You get a much better hearing aid now than you did even 10 years ago. But if you’re not keeping your eye on them, these advanced features can cause faster battery drain. You can still use your favorite features. But bear in mind, you will have to switch out the battery sooner if you are streaming music from your phone for hours. Bluetooth, multichannel, tinnitus relief, noise canceling — all of these added functions can drain your battery.

Batteries Can be Impacted by Altitude Changes

Moving from a low to high altitude can drain your batteries, particularly if they’re on their last leg. Bring some extra batteries if you are going on a plane or high up into the mountains.

Are The Batteries Really Low?

Some hearing aids let you know when the battery is running low. As a general rule, these alerts are giving you a “heads up”. It doesn’t mean you have a dead battery. On top of this, sometimes an environmental change in altitude or humidity briefly causes the charge to drop and the low battery alarm gets activated. In order to end the alarm, take the batteries out, and then put them back in. You may be able to get a few more hours or possibly even days out of that battery.

Improper Handling of Batteries

You should not remove the little tab from the battery until you’re ready to use it. Make sure you wash your hands before touching your hearing aids or batteries to avoid getting dirt or hand oil on them. Never freeze hearing aid batteries. This technique may increase the life of some kinds of battery but it doesn’t work with hearing aid batteries. Hearing aid batteries may lose battery power faster if you make these simple handling mistakes.

It’s Not a Good Plan to Purchase a Year’s Supply of Batteries

When you can afford to do it, purchasing in bulk can be a smart idea. But as you come to the end of the pack, the last several batteries likely won’t be at full power. Try to stick with a 6-month supply or less unless you’re okay with the waste.

Shopping For Hearing Aid Batteries on The Web

This isn’t a general critique of buying stuff on the web. You can get some good deals. But some batteries that you can find online are being sold by less honest people and are close to their expiration date. They may even be beyond their expiration date. So you need to be careful.
There’s an expiration date on both zinc and alkaline batteries. If you were going to buy milk, you would look at the expiration date. You have to use the same amount of care with batteries. If you’re going to get the most from your pack, make sure the date is well in the future. If the website doesn’t specify an expiration date, message the vendor, or buy batteries directly from us. Make sure you know and trust the seller.

Now You Can Get Rechargeable Hearing Aids

Hearing aids could drain too quickly for a number of reasons. But you can get more life out of your batteries by taking some precautions. You might also consider rechargeable hearing aids if you’re going to buy a new set. You put them on a charger every night for a full charge the next day. And you only need to replace them every few years.
