Does it seem as if your hearing aid batteries drain way too fast? Here are some unexpected reasons that could occur.How long should hearing aid batteries keep a charge? Between 3 to 7 days is typical. That’s a really wide range. In fact, it’s so wide that it probably doesn’t help you predict what should be happening with your hearing aid. Things might suddenly get quiet when you’re trying to hear the cashier at the grocery store after 4 days of battery power. Or perhaps on day 5, you’re enjoying a conversation with friends when you suddenly feel really alone because you can’t hear what anyone is saying. Sometimes the batteries don’t even make 3 days. Like when you’re watching TV on day 2 and all of a sudden you can’t hear the show your watching. It’s more than a little inconvenient. You’re missing out on life because you’re not sure how much juice you have left in your hearing aids. Here are the most likely culprits if your hearing aid batteries drain quickly.

A Battery Can be Depleted by Moisture

Did you know that humans are one of the few species that produce moisture through their skin? We do it to cool down. We do it to get rid of excess sodium or toxins in the blood. You might also live in a climate that’s moist and humid. The air vent in your hearing aid can become clogged by this added moisture and it will be less reliable. It can even drain the battery directly by interacting with the chemicals that generate electricity. Here are some measures you can take to avoid moisture-caused battery drain:

  • Don’t keep your hearing aids in the bathroom, kitchen or other damp environments
  • Get a dehumidifier for your hearing aids
  • Open the battery door before storing the hearing aids
  • if your storing them for a number of days or more, remove the batteries

Batteries Can be Drained by Advanced Hearing Aid Features

Current digital hearing aids help people hear so much better than ones that came out just ten years ago. But if you’re not keeping your eye on them, these advanced functions can cause faster battery drain. You can still use 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. Bluetooth, multichannel, tinnitus relief, noise canceling — all of these extra features can deplete your battery.

Altitude Changes Can Impact Batteries Too

Your batteries can be drained if you go from low to high altitudes especially if they are already low on juice. When flying, skiing or climbing always takes some extra batteries.

Are The Batteries Really Low?

Some models will give you an alert when the battery starts to get too low. Generally speaking, these alerts are giving you a “heads up”. They’re not actually saying the battery is dead. Additionally, the charge can at times dip temporarily due to altitude or environmental changes and that can trigger a false low battery warning. Take the hearing aids out and reset them to stop the alarm. The battery may 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. Always wash your hands before touching your hearing aids or batteries to avoid getting dirt or hand oil on them. Hearing aid batteries should not be frozen. This technique may increase the life of some types of battery but it doesn’t work with hearing aid batteries. Simple handling mistakes like these can cause hearing aid batteries to drain faster.

It’s Not a Good Idea to Buy a Year’s Supply of Batteries

If you can afford to do it, purchasing in bulk can be a smart plan. But the last few batteries in the pack most likely won’t have full power. Unless you don’t mind wasting a few, try to stick to a six month supply.

Buying Hearing Aid Batteries Online

It’s not a broad criticism of buying stuff on the internet. You can get some good deals. But some less honest people will sell batteries on the internet that are very near to the expiration date. They may even be past their expiration date. So buyer beware.
There’s an expiration date on both alkaline and zinc batteries. If you were going to buy milk, you would look at the expiration date. You need to do that with batteries too. If you’re going to get the most from your pack, be certain the date is well in the future. It’s probably a good idea to message the vendor if you don’t see an expiration date or better yet, come see us for your battery needs. Only purchase batteries from reputable sources.
