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 die way too quickly? There are numerous reasons why this might be happening that might be surprising.

So how long should the charge on my hearing aid battery go? The ordinary hearing aid battery lasts anywhere from 3 to 7 days.

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

You could be at market on day 4. All of a sudden, you can’t hear anything. You can’t hear the cashier.

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

Perhaps you go to your grandchild’s school to see a play. You can no longer hear the kids singing. Wait, it’s only day 2. Yes, they even sometimes drain after a couple of days.

It isn’t just inconvenient. You’re missing out on life because you don’t know how much juice is left in your hearing aids.

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

Moisture can drain a battery

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

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

Avoid battery drain caused by moisture with these steps:

  • Store your hearing aids in a place where moisture is minimum
  • A dehumidifier can be helpful
  • Open up the battery door before storing the hearing aids
  • Don’t leave the batteries in if you’re storing them for a few days

Sophisticated modern features are power intensive

Even 10 years ago, hearing aids were much less helpful for people with hearing loss than modern devices. But when these sophisticated functions are being used, they can be a drain on battery power.

Don’t quit 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.

All these added functions, like Bluetooth, tinnitus relief, or multichannel, can drain the battery faster.

Altitude changes can impact batteries too

Your batteries can be drained quickly when you have a quick climb in altitude, and if they’re already low this is especially true. Be certain that you bring some spares if you are in the mountains or on a plane.

Is the battery really drained?

Some hearing aids tell you when the battery is getting low. These warnings, as a general rule, aren’t telling you that your batteries are dead, they’re simply a heads up. On top of this, sometimes an environmental change in humidity or altitude briefly causes the charge to dip and the low battery alarm gets triggered.

You can stop the alarm by removing and resetting your hearing aid. You may be able to get several more hours or even days out of that battery.

Improper handling of batteries

You should never remove the little tab from the battery if you’re not ready to use it. Hand oil or dirt can be an issue for batteries so wash up before handling them. Don’t ever freeze hearing aid batteries. This might extend 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.

Overstocking on batteries isn’t a good plan

Purchasing in bulk is usually a smart money decision when you can afford to do it. But you can anticipate that the last several batteries in the pack won’t last as long. It can be a waste to purchase any more than a 6 month supply.

Buying hearing aid batteries from the internet

This isn’t a broad criticism of buying stuff on the internet. You can find a lot of bargains. But you will also come across some less honest sellers 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. When you purchase milk, you wouldn’t forget to look at the date it expires. 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 you purchase your batteries at a hearing aid center or pharmacy, the expiration date will be on the labeling, but if you’re going to shop online be sure the seller specifies when the batteries will expire. Make sure you look for reviews to be certain you’re buying from a reputable source.

The batteries in hearing aids no longer drain quickly

Hearing aid batteries may drain faster for numerous reasons. But by taking little precautions you can get more energy from each battery. You may also consider rechargeable hearing aids if you’re in the market for a new pair. You will get an entire day of power after every night of recharging. The rechargeable batteries only have to be replaced every few years.
