Does it seem as if your hearing aid batteries drain way too quickly? The reasons for this are sometimes unexpected. What is the average amount of time that your hearing aid batteries should keep a charge? The typical hearing aid battery should last between 3 and 7 days. That’s a really wide range. So wide, actually, that it’s unpredictable and puts you in a serious predicament. You could be on day 4 at the grocery store when suddenly, things get quiet and you can’t hear the cashier. Or maybe on day 5, you’re having an enjoyable conversation with friends when you unexpectedly 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 that’s on. It’s not just annoying. You’re missing out on life because you’re not sure how much battery power is left in your hearing aids. If your hearing aid batteries are draining too rapidly, there are several likely culprits.

A Battery Can be Depleted by Moisture

There aren’t many species that release moisture through their skin but humans do. It’s a cooling mechanism. It’s the body’s way of ridding the blood of sodium and toxins. On top of this, you might live in a humid or rainy climate where things get even more moist. This extra moisture can clog the air vent in your device, making it 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:

  • A dehumidifier for your hearing aid is helpful
  • if your storing them for a number of days or more, remove the batteries
  • When you store your hearing aids, open the battery door
  • Don’t keep your hearing aids in the bathroom, kitchen or other moist environments

Advanced Hearing Aid Functions Can Deplete Batteries

You get a much better hearing aid nowadays than you did even 10 years ago. But these extra features can cause batteries to drain faster if you’re not paying attention. You can still use your favorite features. But remember, you will need to replace the battery sooner if you are streaming music from your phone for hours. Bluetooth, multichannel, tinnitus relief, noise canceling — all of these additional features can deplete 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 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. As a general rule, these warnings are giving you a “heads up”. They’re not actually saying the battery is depleted. On top of this, sometimes an environmental change in humidity or altitude briefly causes the charge to drop and the low battery alert gets activated. In order to stop the alarm, take the batteries out, and then put them back in. The battery may last a few more hours or even days.

Improper Handling of Batteries

Wait until you’re ready to use your hearing aid to remove the tab from the battery. Refrain from getting skin oil and dirt on your hearing aid by washing your hands before touching them. Never freeze hearing aid batteries. It doesn’t extend their life as it could with other kinds of batteries. Hearing aid batteries may lose battery power faster if you make these simple handling mistakes.

Buying a Year’s Supply of Batteries Isn’t a Good Idea

Buying in bulk is typically a smart money decision if you can afford to do it. But as you get toward the end of the pack, the last several batteries probably won’t last as long. Unless you don’t mind wasting a few, try to stick to a six month supply.

Shopping For Hearing Aid Batteries on The Web

Shopping online can be a good thing. There are some really good deals out in cyberspace. But some less honest people sell batteries online that are very close to the expiration date. Or even worse, it has already passed. So buyer beware.
There’s an expiration date on both zinc and alkaline batteries. You shouldn’t buy milk without looking at the expiration. You need to do that with batteries too. Make sure that the date is well in the future to get the most use out of the pack. It’s probably a smart idea to message the vendor if you don’t see an expiration date or better yet, come see us for your battery needs. Be sure you know and trust the seller.
