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 numerous reasons why this might be occurring that might be unexpected.

So how long should the charge on my hearing aid battery go? From 3 to 7 days is the standard amount of time for charge to last.

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

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

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

Maybe you go to your grandchild’s school to see a play. You can no longer hear the children singing. But it’s only day 2. Yes, they even occasionally die after a couple of days.

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

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

Moisture can drain a battery

Producing moisture through our skin is one thing that human beings 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. Your battery could be exposed to even more moisture if you live in a humid or rainy place.

This extra moisture can clog the air vent in your device, making hearing aids less efficient. It can even kill the battery directly by interacting with the chemicals that make electricity.

Prevent battery drain caused by moisture using these steps:

  • Store your hearing aids in a place where moisture is minimum
  • A dehumidifier can be helpful
  • Open the battery door before storing the hearing aids
  • If you’re storing your hearing aids for a prolonged time period, take out the batteries

Advanced hearing aid features can drain batteries

Modern digital hearing aids help people hear so much better than ones that came out only a decade ago. But when these advanced features are in use, they can be a drain on battery power.

That doesn’t mean you should stop using these amazing 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.

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

Batteries can be impacted by altitude changes

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

Maybe the batteries aren’t really drained

Some hearing aids tell you when the battery is low. These warnings, as a general rule, aren’t telling you that your batteries are dead, they’re just a heads up. Moreover, sometimes an environmental change in humidity or altitude briefly causes the charge to dip and the low battery alarm will sound.

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

Incorrect handling of batteries

Wait until you’re ready to use the battery before you remove the protective tab. Always wash your hands before handling your hearing aids or batteries to avoid getting hand oil or dirt on them. Never freeze hearing aid batteries. This may increase the life of other batteries but that’s not the case with hearing aid batteries.

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

Overstocking on batteries isn’t a good plan

It’s often a wise financial decision to purchase in bulk. But as you get toward the end of the pack, the last few batteries likely won’t last as long. It can be a waste to purchase any more than 6 months worth.

Online battery vendors

We’re not saying it’s necessarily a bad idea to buy things on the internet. You can find lots of bargains. But you will also find some less honest sellers who will sell batteries that are close to or even past their expiration date.

Most kinds 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. Make sure that the date is far enough in the future to get the most use out of the pack.

If you buy your batteries at a hearing aid store or pharmacy, the expiration date will be on the labeling, but if you’re going to shop online be sure the vendor specifies when the batteries will expire. Only purchase batteries from trustworthy sources.

Hearing aid batteries drain quickly no more

There are numerous reasons that hearing aid batteries might drain quickly. But by taking small precautions you can get more power from each battery. And if you’re thinking of an upgrade, consider rechargeable hearing aids. You will get a full day of power after each night of recharging. Every few years, you will need to replace the rechargeable batteries.
