Do you feel like your hearing aid batteries are not keeping a charge as long as they should? The reasons for this are sometimes unexpected.What is the average amount of time that your hearing aid batteries should keep a charge? The normal hearing aid battery should last anywhere from 3 to 7 days. That’s a very wide range. So wide, actually, that it’s unpredictable and leaves you in a serious predicament. You might be on day 4 at the grocery store when unexpectedly, things get quiet and you’re unable to hear the cashier. Or maybe on day 5, you’re having an enjoyable conversation with friends when you suddenly feel very alone because you can’t participate because you can’t hear. Occasionally the batteries don’t even make 3 days. 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 juice you have left in your hearing aids. Here are the likely culprits if your hearing aid batteries die too soon.

Moisture Can Deplete a Battery

Did you realize that humans are one of the few species that release moisture through their skin? It’s a cooling method. We do it to get rid of excess sodium or toxins in the blood. Moreover, you may live in a rainy or humid climate where things get even more moist. This excess moisture can clog the air vent in your device, making it less efficient. It can even deplete the battery directly by interacting with the chemicals that create electricity. Here are some steps you can take to avoid moisture-caused battery drain:

  • Don’t keep your hearing aids in the bathroom, kitchen or other moist environments
  • Don’t leave the batteries in if you’re storing them for a few days
  • Get a dehumidifier for your hearing aids
  • Before you store your hearing aids, open the battery door

Advanced Hearing Aid Functions Can Run Down Batteries

You get a much better hearing aid today than you did even ten years ago. But if you’re not paying attention, these advanced functions can cause faster battery drain. Don’t avoid using your favorite features. But just know that if you stream music for hours from your mobile device to your hearing aids, you’ll have to replace the battery sooner. Bluetooth, multichannel, tinnitus relief, noise canceling — all of these extra functions can deplete your battery.

Batteries Can be Affected 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 brings some extra batteries.

Perhaps The Batteries Aren’t Really Low

Some models will give you an alert when the battery starts to get too low. Generally speaking, these alerts are giving you a “heads up”. They’re not actually saying the battery is depleted. In addition, sometimes an environmental change in altitude or humidity briefly causes the charge to dip and the low battery alert gets activated. In order to end the alarm, remove the batteries, and then put them back in. You may be able to get several more hours or possibly even days of battery life.

Handling Batteries Improperly

Wait until you’re ready to use your hearing aid to pull the tab from the battery. Make sure you wash your hands before touching your hearing aids or batteries to avoid getting hand oil or dirt on them. Never freeze hearing aid batteries. It doesn’t increase their life as it could with other types of batteries. Basic handling mistakes like these can make hearing aid batteries drain more quickly.

Purchasing a Year’s Supply of Batteries Isn’t a Very Good Plan

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

Buying Hearing Aid Batteries Online

It’s not a broad critique of buying things online. There are some really great deals out in cyberspace. But some batteries that you can find online are being sold by less honest individuals and are near their expiration date. Or worse, it has already passed. So you need to be careful.
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 check the expiration date. You have to use the same amount of caution with batteries. 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 there isn’t an expiration date or better yet, come see us for your battery needs. Only buy batteries from trusted sources.

Modern Hearing Aids Are Rechargeable

There are a number of reasons that hearing batteries might drain rapidly. But by taking some precautions you can get more life from each battery. If you’re in the market for a new set of hearing aids, you might decide on a rechargeable model. You dock them on a charger every night for a full day of hearing the next day. And you only have to change them every few years.
