Man touching hearing aids that stopped working because the batteries drained.

Does it seem as if your hearing aid batteries lose their charge too quickly? The reasons for this can be sometimes unexpected.What is the average amount of time that your hearing aid batteries should keep a charge? Between 3 to 7 days is normal. That range is pretty wide. As a matter of fact, it’s so wide that it probably doesn’t help you predict what should be taking place with your hearing aid. Things might suddenly go quiet when you’re trying to hear the cashier at the grocery store after 4 days of battery power. Or it’s day 5 and you’re enjoying a call with friends when all of a sudden you find yourself feeling really alone because you can no longer follow the conversation. Occasionally the batteries don’t even make 3 days. Like when you’re watching TV on day 2 and suddenly you can’t hear the show your that’s on. It’s not just inconvenient. You just can’t tell how much battery power you have left in your hearing aids and it’s causing you to miss out on life. Here are the most likely culprits if your hearing aid batteries drain too soon.

Moisture Can Deplete a Battery

There aren’t very many species that produce moisture through their skin but humans do. It’s a cooling method. We do it to clear out excess toxins or sodium in the blood. You may also live in a climate that’s moist and humid. The air vent in your hearing aid can get clogged by this extra moisture and it will be less effective. Moisture can also mix with the chemicals of the battery causing it to drain faster. Here are a few steps you can take to prevent moisture-caused battery drain:

  • if your storing them for a few days or more, remove the batteries
  • Before you store your hearing aids, open the battery door
  • A dehumidifier for your hearing aid is recommended
  • Moist environments, like the kitchen or bathroom are not a good place to keep your hearing aids

Advanced Hearing Aid Features Can Deplete Batteries

Modern digital hearing aids help people hear so much better than ones that you could get just ten years ago. But these extra features can cause batteries to run down faster if you’re not paying attention. Don’t stop using your favorite features. But keep in mind, you will have to replace the battery sooner if you are streaming music from your phone all day. Your battery can be drained by any of the advanced functions, like Bluetooth, multichannel, noise cancellation, and tinnitus relief.

Altitude Changes Can Impact Batteries Too

Going from a low to high altitude can drain your batteries, specifically if they’re on their older. Bring some spare batteries if you are going on a plane or high up into the mountains.

Are The Batteries Really Low?

Some models will give you a warning when the battery begins to get too low. These warnings are, under normal circumstances, a “heads up”. It doesn’t mean you have a dead battery. Furthermore, the charge can sometimes dip temporarily due to environmental or altitude changes and that can activate a false low battery warning. Remove the hearing aids and reset them to stop the alarm. The battery might last several more hours or even days.

Improper Handling of Batteries

Wait until you’re about to use your hearing aid to pull the tab from the battery. Steer clear of getting skin oil and dirt on your hearing aid by washing your hands before touching them. Hearing aid batteries should never be frozen. It doesn’t increase their life as it could with other types of batteries. Simple handling mistakes like these can make hearing aid batteries drain faster.

Purchasing a Year’s Supply of Batteries Isn’t a Good Plan

If you can afford to do it, purchasing in bulk can be a smart idea. But as you come to the end of the pack, the last few batteries most likely won’t last as long. Try to stick with a 6-month supply or less unless you’re okay with the waste.

Purchasing Hearing Aid Batteries on The Web

It’s not a general critique of buying stuff on the web. There are some really great deals out in cyberspace. But some less scrupulous people sell batteries on the internet that are very near to the expiration date. They may even be past their expiration date. So you need to be careful.
Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have an expiration date. You wouldn’t buy milk without checking the expiration. You need to do that with batteries also. If you want to get the most from your pack, make sure the date is well in the future. It’s probably a smart idea to message the vendor if you don’t see an expiration date or even better, come see us for your battery needs. Only purchase batteries from reliable sources.

Today You Can Get Rechargeable Hearing Aids

There are a number of reasons that hearing batteries might drain rapidly. But you can get more power from your batteries by taking some precautions. If you’re in the market for a new set of hearing aids, you might consider a rechargeable model. You put them on a charger every night for a full day of hearing the next day. The rechargeable batteries only have to be replaced every few years.
