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 ought to? There are several reasons why this may be taking place that may be unexpected.

So how far should the charge on my hearing aid battery last? 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 could leave you in trouble.

You could be on day 4 at the grocery store. Suddenly, things get quiet. The cashier is talking to you but you can’t hear what they are saying.

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

Maybe you go to your grandchild’s school to see a play. And the kid’s singing disappears. Wait, it’s just day 2. Yes, they even occasionally drain after a couple of days.

It isn’t only inconvenient. You’re missing out on life because you’re not sure how much power you have left in your hearing aids.

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

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 helps clear the blood of unwanted toxins and sodium. In addition, you may live in a humid or rainy climate where things get even wetter.

This excess moisture can clog up the air vent in your device, making hearing aids less efficient. It can even interact with the chemicals that generate electricity causing it to drain even faster.

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

  • Don’t leave the batteries in if you’re storing them for several days
  • Before going to bed, open up the battery door
  • Don’t keep your hearing aids in the bathroom or kitchen
  • Get a dehumidifier

Advanced hearing aid features can drain batteries

Even 10 years ago, hearing aids were a lot less helpful for people with hearing loss than current devices. But these added functions can cause batteries to drain more quickly if you’re not watching.

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 extra features, like Bluetooth, tinnitus relief, or multichannel, can drain the battery faster.

Altitude changes can affect batteries as well

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

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. On top of this, sometimes an environmental change in humidity or altitude briefly causes the charge to drop and the low battery alarm will sound.

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

Handling the batteries incorrectly

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. Keep your batteries away from the freezer. It doesn’t increase their life as it might with other types of batteries.

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

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

Buying in bulk is often a smart money decision when you can afford to do it. But you can anticipate that the last few batteries in the pack will drain faster. Try to limit yourself to a 6-month supply or less unless you’re okay with the waste.

Online battery vendors

This isn’t a broad critique of buying things online. You can get some great deals. But some less honest individuals will sell batteries online that are very close to the expiration date. Or even worse, it has already gone by.

Most types of batteries, including hearing aid batteries, have expiration dates. When you purchase milk, you wouldn’t forget to check the date it expires. The same goes with batteries. In order to get the most out of your battery, be certain 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 packaging, but if you’re going to shop on the internet be sure the vendor states when the batteries will expire. Make sure you look for reviews to be certain you’re purchasing from a reputable source.

The batteries in hearing aids no longer drain quickly

There are numerous reasons that hearing aid batteries may drain quickly. But by taking small precautions you can get more power from each battery. You may also consider rechargeable hearing aids if you’re shopping for a new set. You put these hearing aids on a charger every night for an entire day of hearing tomorrow. The rechargeable batteries only need to be replaced every few years.
