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 die quicker than they ought to? There are numerous reasons why this may be happening that might be unexpected.

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

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

You may be at market on day 4. Out of the blue, you can’t hear anything. 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. All of a sudden, you can’t hear the conversation and it’s leaving you feeling rather alone.

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

It’s not simply inconvenient. You’re losing out on life because you don’t know how much juice you have left in your hearing aids.

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

Moisture can drain a battery

Releasing moisture through our skin is one thing that humans do that the majority of other species don’t. It’s a cooling system. You do it to remove excess sodium or toxins in the blood. Your battery may be subjected to even more moisture if you live in a humid or rainy setting.

The air vent in your device can get clogged by this extra moisture which can cause less efficient performance. It can even interact with the chemicals that generate electricity causing it to drain even faster.

Prevent battery drain caused by moisture with these steps:

  • A dehumidifier can be helpful
  • Keep your hearing aids in a place where moisture is at a minimum
  • Before going to bed, open the battery door
  • Take the batteries out if you’re storing them for a few days

Advanced hearing aid features can drain batteries

Current digital hearing aids help people hear so much better than ones that came out only 10 years ago. 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 for hours from your smartphone to your hearing aids, you’ll need to change the battery sooner.

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

Altitude changes can affect batteries too

Going from a low to high altitude can drain your batteries, particularly if they’re on their last leg. Be certain that you bring some spares if you’re in the mountains or on an aircraft.

Maybe the batteries aren’t really drained

Many hearing aids will alert you when the batteries need to be changed. These warnings, as a general rule, aren’t telling you that your batteries are dead, they’re simply a heads up. Moreover, sometimes an environmental change in altitude or humidity temporarily causes the charge to dip and the low battery alarm will sound.

Take out the hearing aids and reset them to stop the alarm. You might be able to get several more hours or even days out of that battery.

Improper handling of batteries

Wait until you’re ready to use the battery before you remove the protective tab. Hand oil or dirt can be a problem for batteries so wash up before handling them. Keep your batteries out of the freezer. This may increase the life of other batteries but that’s not the case with hearing aid batteries.

Basic handling mistakes like these can make hearing aid batteries drain quickly.

Overstocking on batteries isn’t a good plan

Buying in bulk is often a smart money decision when you can afford to do it. But as you get toward the end of the pack, the last few batteries likely won’t last as long. Try to limit yourself to a 6-month supply or less unless you’re okay 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 you will also come across some less honest vendors 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 buy milk without looking at the expiration. The same goes with batteries. Be certain that the date is far enough in the future to get the most usage out of the pack.

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

Hearing aid batteries drain quickly no more

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 think about rechargeable hearing aids if you’re in the market 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.
