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? Here are some surprising reasons that might occur.

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 really wide range. So wide, in fact, that it’s unpredictable and leaves you in a serious predicament.

You could be at market on day 4. Unexpectedly, your sound cuts out. You don’t hear the cashier.

Or, you’re out for lunch with friends on day 5. Suddenly, you find yourself feeling really alone because you can no longer follow what your friends are saying.

Perhaps you go to your grandchild’s school to see a play. And the children’s singing goes quiet. Wait, it’s just day 2. Yes, sometimes they even drain before the 3rd day.

It’s more than 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 causes if your hearing aid batteries die quickly.

Your Battery can be drained by moisture

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

This excess moisture can clog 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 avoid moisture-caused battery drain:

  • A dehumidifier is helpful
  • Store your hearing aids in a spot where moisture is at a minimum
  • If you’re storing your hearing aids for a prolonged time period, take out the batteries
  • Before you go to bed, open up the battery door

State-of-the-art hearing aid features can run down batteries

Even a decade 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 be aware that the battery will drain faster if you spend all day streaming music from your cellphone to your hearing aids.

Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these added 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 low already. When flying, climbing, or skiing always takes some spares.

Perhaps the batteries aren’t really 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. Additionally, you might get a warning when the charge drops because of 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 power left.

Incorrect handling of batteries

You shouldn’t remove the little tab from the battery before you’re 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 extend their life as it might with other kinds of batteries.

Simple handling errors like these can make hearing aid batteries drain quickly.

Overstocking on batteries isn’t a good plan

Buying in bulk is usually a smart money choice when you can afford it. But as you get toward the end of the pack, the last several batteries likely won’t last as long. It can be a waste to purchase any more than 6 months worth.

Buying hearing aid batteries from the internet

This isn’t a broad criticism of buying stuff online. You can find lots of bargains. But you will also come across 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 an expiration date. You wouldn’t purchase milk without looking at when it expires. You shouldn’t do that with batteries either. Be certain that the date is well in the future to get the most usage out of the pack.

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

Hearing aid batteries drain quickly no more

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