Hearing Aid Batteries Drain Quickly Because of This

Button battery for hearing aids on the brown wooden table. The object is on the left. The batteries are stacked in a triangle.

Do your hearing aid batteries seem to die faster than they ought to? Here are some surprising reasons that might happen.

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

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

You could be at market on day 4. Out of the blue, you can’t hear anything. You can’t hear the cashier.

Or, you’re out for dinner with friends on day 5. All of a sudden, you can’t hear the discussion and it’s leaving you feeling quite alone.

Now, you’re attending your grandchild’s school play. You can no longer hear the kids singing. But it’s only day 2. Yes, they even sometimes die after a couple of days.

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

Here are 7 possible culprits if your hearing aid batteries drain quickly.

Moisture can kill a battery

Did you know that humans are one of the few species that discharge moisture through their skin? It’s a cooling system. It also helps clear the blood of excess toxins and sodium. Your battery may be subjected to even more moisture if you live in a humid or rainy setting.

This extra moisture can clog up the air vent in your device, making hearing aids less efficient. It can even drain the battery directly by interacting with the chemicals that generate electricity.

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

  • If you’re storing your hearing aids for an extended time period, remove the batteries
  • Before going to bed, open up the battery door
  • Don’t keep your hearing aids in the kitchen or bathroom
  • A dehumidifier is helpful

Advanced hearing aid functions can run down batteries

Current digital hearing aids help people hear so much better than ones that came out only 10 years ago. But these added functions can cause batteries to drain faster if you’re not watching.

Don’t quit using your favorite features. But just know that if you stream music for hours 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 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 are in the mountains or on a plane.

Is the battery really drained?

Some hearing aids let you know when the battery is low. Generally, these warnings are giving you a “heads up”. They’re not telling you the battery is dead. Additionally, you may get a warning when the charge takes a dip due to an altitude or humidity change.

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

Improper handling of batteries

Wait until it’s time to use the battery before you remove the protective tab. Always wash your hands before handling your hearing aids or batteries to avoid getting hand oil or dirt on them. Never freeze hearing aid batteries. It doesn’t increase their life as it might with other kinds of batteries.

Simple handling mistakes like these can make hearing aid batteries drain faster.

Overstocking on batteries isn’t a good plan

It’s often a practical financial choice to buy in bulk. But as you get toward the end of the pack, the last few batteries most likely won’t last as long. It can be a waste to purchase any more than a 6 month supply.

Online battery vendors

We’re not suggesting it’s automatically a bad idea to purchase things on the internet. You can find lots of bargains. But you will also come across some less honest vendors who will sell batteries that are close to or even past their expiration date.

Most kinds of batteries, including hearing aid batteries, have expiration dates. You wouldn’t buy milk without looking at when it expires. The same goes with batteries. In order to get the most out of your battery, make sure the date is well into the future.

If you purchase your batteries at a hearing aid store or pharmacy, the expiration date will be on the packaging, but if you’re going to shop online make sure the seller states when the batteries will expire. Make sure you check reviews to be certain you’re buying from a trustworthy source.

Hearing aid batteries drain quickly no more

There are several reasons that hearing aid batteries may drain quickly. But you can get more power from each battery by taking little precautions. You might also think about rechargeable hearing aids if you’re shopping for a new pair. You will get an entire day of power after every night of recharging. The rechargeable batteries only have to be swapped out every few years.
