This is Why Hearing Aid Batteries Drain so Fast

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

Does it seem as if your hearing aid batteries drain way too quickly? There are several reasons why this might be taking place that may be surprising.

So how long should the charge on my hearing aid battery go? From 3 to 7 days is the standard amount of time for charge to last.

That range is rather wide. So wide, in fact, that it’s unpredictable and leaves you in a serious situation.

You could be at market on day 4. All of a sudden, you can’t hear anything. The cashier is talking to you but you can’t hear what they are saying.

Or it’s day 5. You’re appreciating a night out with friends. Suddenly, you find yourself feeling really alone because you can no longer follow what your friends are saying.

Now, you’re attending your grandson’s school play. And the kid’s singing goes quiet. Wait, it’s just day 2. Yes, they even occasionally die after a couple of days.

It’s more than inconvenient. You have no clue how much power is left and it’s causing you to miss out on life.

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

Moisture can drain a battery

Did you realize that human beings are one of the few species that release moisture through their skin? It’s a cooling system. It also helps clear the blood of unwanted toxins and sodium. On top of this, you might live in a humid or rainy climate where things get even wetter.

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

Prevent battery drain related to moisture using these steps:

  • Take the batteries out if you’re storing them for several days
  • Store your hearing aids in a place where moisture is at a minimum
  • Open the battery door before storing the hearing aids
  • Get a dehumidifier

Advanced modern features are power intensive

Even 10 years ago, hearing aids were a lot less helpful for people with hearing loss than current devices. But when these advanced features are in use, they can be a draw on battery power.

That doesn’t mean you shouldn’t use these amazing 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 features can drain your battery.

Batteries can be impacted by altitude changes

Going from a low to high altitude can deplete your batteries, particularly if they’re on their last leg. When flying, climbing, or skiing remember to bring some spares.

Is the battery actually drained?

Many hearing aids will alert 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 might get a warning when the charge drops because of an altitude or humidity change.

You can turn off the alarm by removing and resetting your hearing aid. There could be hours or even days of power left.

Incorrect handling of batteries

You should never pull off the little tab from the battery before you’re ready to use it. Hand oil or dirt can be a problem for batteries so wash up before handling them. Keep your batteries out of the freezer. This may increase the life of other batteries but it doesn’t work with hearing aid batteries.

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

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

It’s usually a practical financial choice to purchase in bulk. But you can anticipate that the last few batteries in the pack won’t last as long. Try to limit yourself to a 6-month supply or less unless you’re fine with the waste.

Buying hearing aid batteries online

This isn’t a general critique of buying things on the internet. You can find a lot of bargains. But you will also find some less honest sellers 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. When you buy milk, you wouldn’t forget to look at the expiration date. You shouldn’t forget to check the date on batteries either. In order to get the most from your battery, make sure the date is well into the future.

If the website doesn’t state an expiration date, message the seller, or purchase batteries at a pharmacy or hearing aid store where you can see it on the packaging. Make sure you check reviews to be certain you’re buying from a reputable source.

Hearing aid batteries drain quickly no more

Hearing aid batteries might drain faster for several reasons. But you can get more power from each battery by taking small precautions. And if you’re thinking of an upgrade, consider rechargeable hearing aids. You will get an entire day of power after each night of recharging. The rechargeable batteries only have to be swapped out every few years.
