HEARING TIPS

Does it seem like your hearing aid batteries drain way too fast? There are numerous reasons why this might be occurring that might be surprising.

How long should hearing aid batteries last? From 3 to 7 days is the standard time-frame for charge to last.

That’s a really wide range. So wide, in fact, that it’s unpredictable and leaves you in a serious predicament.

You could be at the store on day 4. Out of the blue, you can’t hear anything. The cashier is speaking to you but you don’t hear what they are saying.

Or it’s day 5. You’re appreciating a night out with friends. All of a sudden, you can’t hear the discussion and it’s leaving you feeling rather alone.

Maybe you go to your grandchild’s school to watch a play. And the children’s singing disappears. Wait, it’s just day 2. Yes, they even occasionally drain after a couple of days.

It’s not only inconvenient. You’re missing out on life because you don’t know how much power you have left in your hearing aids.

If your hearing aid batteries drain too quickly, check out these seven possible culprits.

Your Battery can be drained by moisture

Releasing moisture through our skin is one thing that human beings do that the majority of other species don’t. It’s a cooling mechanism. You do it to remove excess sodium or toxins in the blood. In addition, you might live in a rainy humid climate where things get even wetter.

The air vent in your device can get clogged by this excess moisture which can result in less efficient functionality. It can even interact with the chemicals that produce electricity causing it to drain even faster.

Here are several steps you can take to avoid moisture-caused battery drain:

  • Before you go to bed, open up the battery door
  • Get a dehumidifier
  • Take the batteries out if you’re storing them for several days
  • Store your hearing aids in a place where moisture is minimum

Advanced hearing aid functions can drain batteries

Current digital hearing aids help individuals hear so much better than ones that came out just a decade ago. But when these sophisticated features are in use, they can be a drain on battery power.

Don’t quit using your favorite features. But be aware that the battery will die faster if you spend hours streaming music from your phone to your hearing aids.

Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these extra functions can drain your battery.

Batteries can be impacted by altitude changes

Going from a low to high altitude can drain your batteries, particularly if they’re low already. Make sure you bring some spares if you’re in the mountains or on a plane.

Perhaps the batteries aren’t actually drained

Many hearing aids will warn you when the batteries need to be replaced. These warnings, generally speaking, aren’t telling you that your batteries are dead, they’re simply a heads up. In addition, you may get a warning when the charge drops due to an altitude or humidity change.

Take the hearing aids out and reset them to stop the alarm. There could be hours or even days of juice left.

Handling the batteries improperly

Wait until you’re ready to use the battery before you remove the protective tab. Hand oil or dirt can be an issue for batteries so wash up before you handle them. Don’t ever freeze hearing aid batteries. It doesn’t increase their life as it might with other kinds of batteries.

Hearing aids will drain faster if you mishandle them in these ways.

Purchasing a year’s supply of batteries isn’t a great idea

Purchasing in bulk is usually a smart money decision when you can afford to do it. But you can anticipate that the last few batteries in the pack will drain faster. It can be a waste to buy any more than 6 months worth.

internet battery vendors

We’re not claiming it’s always a bad idea to purchase things on the internet. You can find a lot of bargains. But some less honest people will sell batteries online that are very near to the expiration date. Or even worse, it has already passed.

Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have an expiration date. You wouldn’t purchase milk without looking at the expiration. You shouldn’t do that with batteries either. In order to get the most from your battery, be certain the date is well into the future.

If you purchase your batteries at a hearing aid center or pharmacy, the expiration date will be on the labeling, but if you are going to shop on the internet be sure the vendor states when the batteries will expire. Only buy batteries from reputable sources.

The batteries in hearing aids no longer drain quickly

Hearing aid batteries may drain faster for numerous reasons. But you can get more power from each battery by taking small precautions. And if you’re considering an upgrade, think about rechargeable hearing aids. You put these hearing aids on a charger each night for an entire day of hearing tomorrow. Every few years, you will have to change the rechargeable batteries.
