Do you feel as if your hearing aid batteries are not keeping a charge as long as they should? Here are some surprising reasons that might occur.What is the average amount of time that your hearing aid batteries should keep a charge? Anywhere from 3 to 7 days is typical. That’s a really wide range. So wide, in fact, that it’s unpredictable and leaves you in a challenging predicament. You might be on day 4 at the grocery store when all of a sudden, things get quiet and you’re unable to hear the cashier. Or perhaps on day 5, you’re having an enjoyable conversation with friends when you suddenly 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 annoying. You simply 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

There aren’t many species that release moisture through their skin but humans do. We do it to cool down. It’s the body’s way of ridding the blood of sodium and toxins. You may also live in a climate that is moist and humid. The air vent in your hearing aid can become clogged by this extra moisture and it will be less reliable. It can even drain the battery directly by interacting with the chemicals which produce electricity. Here are some measures you can take to prevent moisture-caused battery drain:

  • Get a dehumidifier for your hearing aids
  • Moist conditions, like the kitchen or bathroom are not a good place to keep your hearing aids
  • Open the battery door before storing the hearing aids
  • if your storing them for several days or more, remove the batteries

Advanced Hearing Aid Functions Can Run Down Batteries

You get a much better hearing aid today than you did even a decade ago. But if you’re not keeping your eye on them, these advanced functions can cause faster battery drain. Don’t stop using your favorite features. But bear in mind, you will have to replace the battery sooner if you are streaming music from your phone all day. Bluetooth, multichannel, tinnitus relief, noise canceling — all of these extra functions can drain your battery.

Altitude Changes Can Impact Batteries Too

Going from a low to high altitude can sap your batteries, especially if they’re on their last leg. Bring some spare batteries if you are going on a plane or high up into the mountains.

Perhaps The Batteries Aren’t Really Low

Some hearing aids let you know when the battery is running low. These warnings are, ordinarily, a “heads up”. It doesn’t mean you have a dead battery. Moreover, sometimes an environmental change in humidity or altitude temporarily causes the charge to drop and the low battery alert gets triggered. In order to stop the alarm, remove the batteries, and then put them back in. The battery may last a few more hours or even days.

Handling Batteries Improperly

You should never remove the little tab from the battery before you’re ready to use it. Steer clear of getting dirt and skin oil on your hearing aid by cleansing your hands before handling them. Hearing aid batteries should never be frozen. This technique might increase 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 errors.

It isn’t a Good Idea to Buy a Year’s Supply of Batteries

Buying in bulk is usually a smart money move when you can afford to do it. But as you come to the end of the pack, the last few batteries probably won’t be at full power. Unless you don’t mind wasting a few, try to stick to a six month supply.

Shopping For 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 less honest people sell batteries on the internet that are very close to the expiration date. Or worse, they are already passed. So you need to be careful.
Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have an expiration date. You shouldn’t buy milk without checking the expiration date. You have to use the same amount of care with batteries. If you want to get the most from your pack, be sure the date is well in the future. It’s probably a good idea to message the vendor if you don’t see an expiration date or better yet, come see us for your battery needs. Make sure you know and trust the seller.

Now You Can Get Rechargeable Hearing Aids

There are a number of reasons that hearing batteries may drain quickly. But by taking little precautions you can get more life out of 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 charge the next day. The rechargeable batteries only have to be changed every few years.
