“Man

Do you feel like your hearing aid batteries won’t keep a charge as long as they should? The reasons for this can be sometimes surprising.How long should hearing aid batteries last? Anywhere from 3 to 7 days is normal. That range is fairly wide. Actually, it’s so wide that it probably won’t help you predict what should be taking place with your hearing aid. Things could suddenly get quiet when you’re trying to hear the cashier at the grocery store after 4 days of battery power. Or it’s day 5 and you’re enjoying a call with friends when all of a sudden 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. Hold on, it’s only day 2. Yes, occasionally they even die before that 3-day mark. It’s more than a little inconvenient. You just can’t tell how much battery power your hearing aids have left and it’s making you miss out on life. Here are the most likely culprits if your hearing aid batteries die quickly.

A Battery Can be Depleted by Moisture

Did you realize that humans are one of the few species that release moisture through their skin? We do it to cool down. We do it to get rid of excess toxins or sodium in the blood. You might also live in a climate that’s 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 deplete the battery directly by interacting with the chemicals which create electricity. Here are a few steps you can take to avoid moisture-caused battery drain:

  • Obtain 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
  • Don’t leave the batteries in if you’re storing them for a number of days

Advanced Hearing Aid Functions Can Drain Batteries

Modern digital hearing aids help people hear a lot better than ones that you could get just 10 years ago. But these extra features can cause batteries to run down faster if you’re not keeping an eye on them. Don’t quit using your favorite features. But keep in mind, you will need to replace the battery sooner if you are streaming music from your phone all day. Your battery can be depleted by any of the advanced features, like Bluetooth, multichannel, noise cancellation, and tinnitus relief.

Altitude Changes Can Impact Batteries Too

Going from a low to high altitude can sap 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.

It’s Possible That The Batteries Aren’t Really Low

Some hearing aids let you know when the battery is running low. Generally speaking, these warnings are giving you a “heads up”. They’re not actually saying the battery is depleted. Moreover, sometimes an environmental change in altitude or humidity temporarily causes the charge to drop and the low battery alert gets triggered. Remove the hearing aids and reset them to stop the alarm. You might be able to get a few more hours or possibly even days out of that battery.

Improper Handling of Batteries

You should not take out the little tab from the battery until you’re ready to use it. Steer clear of getting skin oil and dirt on your hearing aid by cleansing your hands before touching them. Never freeze hearing aid batteries. This strategy might extend the life of some kinds of battery but it doesn’t work with hearing aid batteries. Simple handling mistakes such as these can cause hearing aid batteries to drain faster.

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

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. Try to stick with a 6-month supply or less unless you’re okay with the waste.

Buying Hearing Aid Batteries on The Web

Buying from the web can be a good thing. You can get some good deals. But some less scrupulous people will sell batteries on the internet that are very near to the expiration date. Or even worse, they are already passed. So you need to be careful.
There’s an expiration date on both alkaline and zinc batteries. If you were going to buy milk, you would look at the expiration date. You should do that with batteries too. Make sure that the date is not close to the expiration to get the most use out of the pack. If the website doesn’t specify an expiration date, message the vendor, or purchase batteries directly from us. Be sure you know and trust the seller.

Now You Can Get Rechargeable Hearing Aids

Hearing aids might drain too rapidly for several reasons. But you can get more power from your batteries by taking some precautions. If you’re looking to buy 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 replaced every few years.
