Does it seem as if your hearing aid batteries drain way too fast? Here are a few surprising reasons that might occur.

How long should hearing aid batteries last? The ordinary hearing aid battery lasts anywhere between 3 and 7 days.

That’s a very wide range. But it’s so wide that it’s unpredictable and may leave you in trouble.

You might be on day 4 at the grocery store. Unexpectedly, things get quiet. You don’t hear the cashier.

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

Maybe you go to your grandchild’s school to watch a play. You can no longer hear the children singing. Wait, it’s just day 2. Yes, they even sometimes die after a couple of days.

It’s more than annoying. You’re missing out on life because you’re not sure how much juice is left in your hearing aids.

If your hearing aid batteries drain too quickly, look to these seven possible culprits.

Your Battery can be killed by moisture

Producing moisture through our skin is one thing that humans do that the majority of other species don’t. It’s a cooling system. You do it to remove excess sodium or toxins in the blood. Your battery may be subjected to even more moisture if you live in a humid or rainy place.

The air vent in your device can become clogged by this excess moisture which can result in less efficient performance. It can even drain the battery directly by interacting with the chemicals that produce electricity.

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

  • A dehumidifier can be helpful
  • Open the battery door before storing the hearing aids
  • Don’t leave the batteries in if you’re storing them for several days
  • Don’t keep your hearing aids in the bathroom or kitchen

Sophisticated modern features are power intensive

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 being used, they can be a draw on battery power.

Don’t stop using your favorite features. But just know that if you stream music all day from your smartphone to your hearing aids, you’ll need to change the battery sooner.

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 sap your batteries, especially if they’re low already. Make sure you bring some spares if you are in the mountains or on an aircraft.

Maybe the batteries aren’t actually drained

Some hearing aids let you know when the battery is getting low. These warnings, as a general rule, aren’t telling you that your batteries are dead, they’re just a heads up. In addition, you may get a warning when the charge drops because of an altitude or humidity change.

Take the hearing aids out and reset them to quiet the alarm. You may be able to get several more hours or even days out of that battery.

Improper handling of batteries

You should never pull off the little tab from the battery before you’re ready to use it. Make sure you wash your hands before handling your hearing aids or batteries to avoid getting hand oil or dirt on them. Don’t ever freeze hearing aid batteries. This may increase the life of other batteries but that’s not the case with hearing aid batteries.

Simple handling errors like these can make hearing aid batteries drain quickly.

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

Buying in bulk is often a smart money choice when you can afford to do it. But you can expect that the last few batteries in the pack will drain faster. It can be a waste to buy any more than a 6 month supply.

Online battery vendors

We’re not suggesting it’s necessarily a bad idea to buy things online. You can get some great deals. But you will also come across some less honest vendors who will sell batteries that are near to or even past their expiration date.

Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have expiration dates. You wouldn’t buy milk without checking the expiration. The same goes with batteries. If you want to get the most from your battery, make sure the date is well into the future.

If the website doesn’t declare an expiration date, message the seller, or purchase batteries at a pharmacy or hearing aid store where you can see it on the box. Make sure you look for reviews to be certain you’re purchasing from a trustworthy source.

The batteries in hearing aids no longer drain quickly

There are numerous reasons that hearing aid batteries might drain quickly. 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 dock these hearing aids on a charger every night for a full day of hearing tomorrow. Every few years, you will have to change the rechargeable batteries.
