Does it seem as if your hearing aid batteries lose their charge too fast? The reasons for this can be sometimes unexpected. How long should hearing aid batteries keep a charge? Between 3 to 7 days is typical. That range is pretty wide. So wide, actually, that it’s unpredictable and leaves you in a challenging predicament. You may be on day 4 at the grocery store when unexpectedly, things get quiet and you can’t hear the cashier. Or perhaps on day 5, you’re having an enjoyable conversation with friends when you unexpectedly feel really alone because you can’t hear what anyone is saying. Now, you’re watching the TV. You can no longer hear the news. Hold on, it’s only day 2. Yes, sometimes they even die before that 3-day mark. It’s not just inconvenient. You simply can’t tell how much battery power you have left in your hearing aids and it’s causing you to miss out on life. If your hearing aid batteries are draining too rapidly, there are a small number of likely causes.

Moisture Can Drain a Battery

There aren’t very many species that release moisture through their skin but humans do. It’s a cooling method. It’s the body’s way of ridding the blood of toxins and sodium. You may also live in a climate that is moist and humid. The air vent in your hearing aid can become clogged by this additional moisture and it will be less reliable. It can even deplete the battery directly by interacting with the chemicals that create electricity. You can avoid moisture-related battery drainage with these measures:

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

Batteries Can be Drained by Advanced Hearing Aid Functions

Modern digital hearing aids help people hear a lot better than ones that came out just a decade ago. But these extra features can cause batteries to drain faster if you’re not keeping an eye on them. You can still use your favorite features. But bear in mind, you will need to replace the battery sooner if you are streaming music from your phone for hours. Bluetooth, multichannel, tinnitus relief, noise canceling — all of these additional functions can drain your battery.

Batteries Can be Impacted by Altitude Changes

Going from a low to high altitude can sap your batteries, specifically if they’re on their older. When skiing, flying or climbing always takes some extra batteries.

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. Moreover, sometimes an environmental change in altitude or humidity briefly causes the charge to drop and the low battery alert gets activated. In order to end the alarm, remove the batteries, and then put them back in. You might be able to get a few more hours or even days out of that battery.

Handling Batteries Improperly

Wait until you’re about to use your hearing aid to pull the tab from the battery. Always wash your hands before handling your hearing aids or batteries to avoid getting dirt or hand oil on them. Hearing aid batteries should never be frozen. This trick may extend the life of some kinds of battery but it doesn’t work with hearing aid batteries. Simple handling mistakes like these can make hearing aid batteries drain faster.

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

Buying in bulk is usually a smart money decision if you can afford to do it. But the last few batteries in the pack most likely won’t have full power. Unless you’re fine with wasting a few, try to stick to a six month supply.

Buying Hearing Aid Batteries Online

Buying online can be a good thing. There are some pretty good deals out in cyberspace. But some less honest people will sell batteries on the internet that are very near to the expiration date. Or worse, it has already passed. So buyer beware.
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 should do that with batteries also. Be certain that the date is not close to the expiration so that you can get the most use out of the pack. It’s probably a good idea to message the vendor if you don’t see an expiration date or even better, come see us for your battery needs. Be sure you know and trust the seller.

Modern Hearing Aids Are Rechargeable

There are several reasons that hearing batteries could drain quickly. But by taking little precautions you can get more life from each battery. You may also consider rechargeable hearing aids if you’re in the market for 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.
