Hearing Aid Batteries Die 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.

Does it seem like your hearing aid batteries drain way too quickly? Here are some unexpected reasons that may happen.

So how long should the charge on my hearing aid battery go? The standard hearing aid battery lasts anywhere between 3 and 7 days.

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

You may be at the store on day 4. Unexpectedly, things get quiet. The cashier is speaking to you but you don’t hear what they are saying.

Or, you’re out for lunch with friends on day 5. Suddenly, you find yourself feeling very alone because you can no longer follow the conversation.

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

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

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

Your Battery can be killed by moisture

Releasing moisture through our skin is one thing that human beings do that most other species don’t. You do it to cool down. You do it to eliminate extra sodium or toxins in the blood. Your battery could be subjected to even more moisture if you live in a humid or rainy place.

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 produce electricity causing it to drain even faster.

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

  • Use a dehumidifier
  • Open the battery door before storing the hearing aids
  • Take the batteries out if you’re storing them for several days
  • Don’t keep your hearing aids in the bathroom or kitchen

Sophisticated 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 sophisticated functions are in use, they can be a draw on battery power.

Don’t stop 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.

All these extra features, like Bluetooth, tinnitus relief, or multichannel, can drain the battery more quickly.

Batteries can be affected by altitude changes

Going from a low to high altitude can deplete your batteries, particularly if they’re on their last leg. Make sure you bring some spares if you’re in the mountains or on a plane.

Is the battery actually drained?

Many hearing aids will warn you when the batteries need to be changed. Generally, these alerts are giving you a “heads up”. They aren’t telling you the battery is dead. In addition, you may get a warning when the charge drops due to an altitude or humidity change.

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

Handling the batteries improperly

You shouldn’t pull off the little tab from the battery before you’re ready to use it. Always wash your hands before handling your hearing aids or batteries to avoid getting hand oil or dirt on them. Keep your batteries out of the freezer. It doesn’t increase their life as it might with other kinds of batteries.

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

Overstocking on batteries isn’t a good plan

Buying in bulk is usually a smart money decision when you can afford it. But you can expect that the last several 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 always a bad idea to purchase things online. You can get some really good deals. But some less scrupulous people will sell batteries online that are very near to the expiration date. Or worse, it has already gone by.

Most kinds of batteries, including hearing aid batteries, have expiration dates. You wouldn’t purchase milk without looking at the expiration. The same goes with batteries. If you want to get the most out of your battery, make sure the date is well into the future.

If the website doesn’t declare an expiration date, send the online vendor a message, or buy batteries at a pharmacy or hearing aid store where you can see it on the packaging. Only buy batteries from reliable sources.

Hearing aid batteries drain quickly no more

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