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 drain faster than they should? Here are a few unexpected reasons that might happen.

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

That range is pretty wide. But it’s so wide that it’s unpredictable and might leave you in a bind.

You might be on day 4 at the supermarket store. Unexpectedly, your sound cuts out. The cashier is speaking to you but you don’t hear what they are saying.

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

Now, you’re at your grandson’s school play. You can no longer hear the children singing. Wait, it’s only day 2. Yes, occasionally they even die before the 3rd day.

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

Here are 7 possible causes if your hearing aid batteries die quickly.

Moisture can kill a battery

Producing moisture through our skin is one thing that humans do that most other species don’t. It’s a cooling mechanism. You do it to get rid of extra sodium or toxins in the blood. On top of this, you may live in a rainy humid environment where things get even wetter.

This excess moisture can clog up the air vent in your device, affecting the hearing aid’s efficiency. It can even kill the battery directly by interacting with the chemicals that make electricity.

Prevent battery drain related to moisture with these steps:

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

State-of-the-art hearing aid functions can drain batteries

Modern digital hearing aids help individuals hear so much better than ones that came out just 10 years ago. But when these sophisticated features are in use, they can be a drain on battery power.

Don’t stop 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 added features can drain your battery.

Altitude changes can affect batteries too

Your batteries can be quickly depleted when you have a rapid climb in altitude, and if they’re already low this is particularly true. Make sure you bring some spares if you’re in the mountains or on a plane.

Is the battery really drained?

Many hearing aids will alert you when the batteries need to be replaced. Generally, these alerts are giving you a “heads up”. They aren’t telling you the battery is dead. Additionally, you might 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. You might be able to get several more hours or even days from that battery.

Handling the batteries improperly

You shouldn’t remove the little tab from the battery if you’re not 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. Never freeze hearing aid batteries. It doesn’t extend their life as it might with other types of batteries.

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

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

It’s often a wise financial decision to purchase in bulk. But you can anticipate that the last few batteries in the pack will drain faster. Try to stick with a 6-month supply or less unless you’re fine with the waste.

internet battery vendors

We’re not saying it’s automatically a bad idea to buy things online. You can find lots of bargains. But you will also find some less honest sellers who will sell batteries that are close to or even past their expiration date.

Most types 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 buy your batteries at a hearing aid store or pharmacy, the expiration date will be on the labeling, but if you’re going to shop on the internet be sure the seller specifies when the batteries will expire. Make sure you look for reviews to be certain you’re purchasing from a reputable source.

Hearing aid batteries drain quickly no longer

Hearing aid batteries may drain faster for numerous reasons. But by taking small precautions you can get more energy from each battery. And if you’re thinking of an upgrade, think about rechargeable hearing aids. You will get a full day of power after each night of recharging. Every few years, you will need to change the rechargeable batteries.
