“Man

Do you feel like your hearing aid batteries won’t keep a charge as long as they should? Here are some unexpected reasons that might happen. How long should hearing aid batteries last? The ordinary hearing aid battery should last between 3 and 7 days. That range is pretty wide. So wide, actually, that it’s unpredictable and puts you in a significant predicament. Things might 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 unexpectedly you find yourself feeling really 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 isn’t just inconvenient. You’re missing out on life because you’re not sure how much battery power is left in your hearing aids. Here are the likely culprits if your hearing aid batteries die quickly.

Moisture Can Drain 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 humid and moist. This excess moisture can clog the air vent in your device, making it less effective. It can even drain the battery directly by interacting with the chemicals that create electricity. Here are a few steps you can take to avoid moisture-caused battery drain:

  • Don’t leave the batteries in if you’re storing them for several days
  • Get a dehumidifier for your hearing aids
  • Open the battery door when you store the hearing aids
  • Don’t keep your hearing aids in the bathroom, kitchen or other moist conditions

Advanced Hearing Aid Features Can Run Down Batteries

Modern digital hearing aids help people hear a lot better than ones that you could get just ten years 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 have to replace the battery sooner if you are streaming music from your phone all day. Your battery can be drained by any of the advanced features, like multichannel, Bluetooth, noise cancellation, and tinnitus relief.

Batteries Can be Impacted by Altitude Changes

Your batteries can be sapped out if you go from low to high altitudes specifically if they are already low on juice. When skiing, flying or climbing always takes some spare batteries.

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

Some models will give you an alert when the battery starts to get too low. As a general rule, these alerts are giving you a “heads up”. They’re not actually saying the battery is dead. On top of this, sometimes an environmental change in altitude or humidity temporarily causes the charge to drop and the low battery alert gets activated. Remove the hearing aids and reset them to end the alarm. The battery might last a few more hours or even days.

Handling Batteries Improperly

Wait until you’re about to use your hearing aid to remove 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. Don’t ever freeze hearing aid batteries. This trick might extend the life of some kinds of battery but it doesn’t work with hearing aid batteries. Simple handling errors like these can cause hearing aid batteries to drain more quickly.

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

Buying in bulk is usually a smart money decision when 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 Internet

Shopping from the web can be a good thing. There are some really good deals out in cyberspace. But some less scrupulous people will sell batteries online that are very close to the expiration date. Or even worse, it has already passed. So buyer beware.
There’s an expiration date on both alkaline and zinc batteries. You wouldn’t buy milk without checking the expiration. You need to use the same amount of care with batteries. If you’re going to get the most from your pack, be certain the date is well in the future. If the website doesn’t state an expiration date, send the online vendor a message, or buy batteries from us. Make sure you know and trust the seller.

Modern Hearing Aids Are Rechargeable

There are several reasons that hearing batteries may drain rapidly. But you can get more life out of your batteries by taking some precautions. You might also consider rechargeable hearing aids if you’re in the market for a new set. If you charge them while you sleep, you get a full day of hearing the next day. And you only have to change them every few years.
