“Man

Do you feel like your hearing aid batteries are not keeping a charge as long as they should? The reasons for this can be sometimes unexpected.What is the average period of time that your hearing aid batteries should stay charged? The normal hearing aid battery lasts anywhere from 3 to 7 days. That’s a very wide range. So wide, in fact, that it’s unpredictable and puts you in a significant predicament. You may be on day 4 at the grocery store when all of a sudden, things go quiet and you can’t hear the cashier. Or it’s day 5 and you’re having a call with friends when suddenly you find yourself feeling very alone because you can no longer hear the conversation. Now, you’re watching the TV. All of a sudden you can’t hear the news. Wait, it’s only day 2. Yes, sometimes they even die before that 3-day mark. It isn’t just inconvenient. You simply can’t tell how much battery power you have left in your hearing aids and it’s making you miss out on life. If your hearing aid batteries are dying too fast, there are a few likely causes.

Moisture Can Deplete 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. In addition, you may live in a rainy or humid climate where things are even more moist. This excess moisture can clog the air vent in your device, making it less effective. It can even deplete the battery directly by interacting with the chemicals that generate electricity. You can prevent moisture-related battery drainage with these measures:

  • Open the battery door before storing the hearing aids
  • A dehumidifier for your hearing aid is recommended
  • Don’t leave the batteries in when you’re storing them for several days
  • Don’t keep your hearing aids in the bathroom, kitchen or other moist environments

Advanced Hearing Aid Features Can Deplete Batteries

You get a much better hearing aid today than you did even a decade ago. But if you’re not paying attention, these advanced functions can cause faster battery drain. You can still use your favorite features. But be aware that if you stream music all day from your smartphone to your hearing aids, you’ll need to replace the battery sooner. Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these added functions can drain your battery.

Batteries Can be Affected by Altitude Changes

Moving from a low to high altitude can deplete your batteries, specifically if they’re on their older. Take some extra batteries if you are going on a plane or high up into the mountains.

Perhaps The Batteries Aren’t Really Low

Some models will give you an alert when the battery begins to get too low. These warnings are, under normal circumstances, a “heads up”. It doesn’t mean you have a depleted battery. Also, the charge can occasionally drop temporarily due to altitude or environmental changes and that can trigger a false low battery warning. In order to stop the alarm, take the batteries out, 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

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

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

When you can afford to do it, buying in bulk can be a smart plan. But the last few batteries in the pack probably won’t have full power. Try to stick with a 6-month supply or less unless you’re okay with wasting a few.

Shopping For Hearing Aid Batteries on The Internet

Shopping online can be a good thing. There are some pretty good 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. They might even be beyond their expiration date. So you need to be cautious.
There’s an expiration date on both zinc and alkaline batteries. You wouldn’t buy milk without checking the expiration date. You have to use the same amount of care with batteries. Make sure that the date is well in the future to get the most use out of the pack. 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. Only buy batteries from trusted sources.

Today You Can Get Rechargeable Hearing Aids

There are a number of reasons that hearing batteries might drain rapidly. But you can get more life from your batteries by taking some precautions. You may also think about rechargeable hearing aids if you’re going to buy a new set. If you charge them while you sleep, you get a full day of hearing the next day. And you only need to change them every few years.
