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 drain way too quickly? There are several reasons why this might be occurring that might be unexpected.

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

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

You may be at market on day 4. Suddenly, your sound cuts out. The cashier is speaking to you but you can’t hear what they are saying.

Or it’s day 5. You’re appreciating a night out with friends. Suddenly, you find yourself feeling very alone because you can no longer hear the conversation.

Perhaps you go to your grandchild’s school to watch a play. You can no longer hear the children singing. But it’s only day 2. Yes, sometimes they even drain before the 3rd day.

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

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

Your Battery can be drained by moisture

Producing moisture through our skin is one thing that humans do that the majority of other species don’t. You do it to cool down. You do it to remove excess sodium or toxins in the blood. On top of this, you may 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 make electricity causing it to drain even faster.

Avoid battery drain caused by moisture with these steps:

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

Sophisticated modern features are power intensive

Current digital hearing aids help people hear so much better than ones that came out just 10 years ago. But when these advanced features are in use, they can be a drain 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.

Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these extra features can drain your battery.

Batteries can be affected by altitude changes

Your batteries can be quickly depleted when you have a quick climb in altitude, and if they’re already low this is particularly true. When flying, skiing, or climbing remember to bring some spares.

Maybe the batteries aren’t really drained

Many hearing aids will warn you when the batteries need to be replaced. Generally, these alerts are giving you a “heads up”. They’re not telling you the battery is dead. In addition, you might get a warning when the charge drops because of an altitude or humidity change.

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

Handling the batteries incorrectly

Wait until you’re ready to use the battery before you remove the protective tab. Make sure you wash your hands before handling your hearing aids or batteries so you don’t get hand oil or dirt on them. Keep your batteries out of the freezer. This might increase 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 often a smart money decision when you can afford it. But you can expect that the last several batteries in the pack won’t last as long. 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 stuff on the internet. You can get some really good deals. But some less scrupulous individuals will sell batteries online that are very near to the expiration date. Or even worse, it has already gone by.

Most kinds of batteries, including hearing aid batteries, have expiration dates. When you purchase milk, you wouldn’t forget to check the expiration date. You shouldn’t do that with batteries either. Be certain that the date is far enough in the future to get the most use out of the pack.

If you purchase your batteries at a hearing aid store or pharmacy, the expiration date will be on the packaging, but if you are going to shop on the internet make sure the vendor states when the batteries will expire. Make sure you look for reviews to be certain you’re buying from a reputable source.

Hearing aid batteries drain quickly no more

There are several reasons that hearing aid batteries might drain quickly. But you can get more power from each battery by taking little precautions. You may also think about rechargeable hearing aids if you’re in the market for a new pair. You put these hearing aids on a charger every night for a full day of hearing tomorrow. The rechargeable batteries only have to be replaced every few years.
