Do you feel as if your hearing aid batteries are not keeping a charge as long as they should? Here are some surprising reasons that could happen.What is the average length of time that your hearing aid batteries should keep a charge? Anywhere from 3 to 7 days is typical. That range is fairly wide. In fact, it’s so wide that it probably won’t help you predict what should be taking place with your hearing aid. Things might suddenly get quiet when you’re trying to hear the cashier at the supermarket after 4 days of battery power. Or it’s day 5 and you’re having a call with friends when suddenly 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 watching. It’s more than a little inconvenient. You simply can’t tell how much battery power you have left in your hearing aids and it’s making you miss out on life. If your hearing aid batteries are draining too fast, there are a small number of likely causes.

Moisture Can Drain a Battery

There aren’t very many species that produce moisture through their skin but humans do. We do it to cool down. It’s the body’s way of purging the blood of sodium and toxins. In addition, you might live in a humid or rainy climate where things are even more moist. The air vent in your hearing aid can get clogged by this extra moisture and it will be less efficient. 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:

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

Advanced Hearing Aid Features Can Run Down Batteries

Current digital hearing aids help people hear so much better than ones that came out just ten years ago. But if you’re not paying attention, these advanced features can cause faster battery drain. Don’t stop using your favorite features. But keep in mind, you will need to replace the battery sooner if you are streaming music from your phone for hours. Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these added features can drain your battery.

Altitude Changes Can Impact Batteries Too

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

Are The Batteries Really Low?

Some models will give you a warning when the battery begins to get too low. These alerts are, ordinarily, a “heads up”. It doesn’t mean you have a dead battery. Furthermore, the charge can at times drop briefly due to altitude or environmental changes and that can cause a false low battery warning. Take the hearing aids out and reset them to end the alarm. You may be able to get a few more hours or even days of battery life.

Improper Handling of Batteries

Wait until you’re about 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 handling them. Don’t ever freeze hearing aid batteries. This strategy may extend the life of some kinds of battery but it doesn’t work with hearing aid batteries. Hearing aid batteries might lose battery power more quickly if you make these basic handling errors.

Buying a Year’s Supply of Batteries Isn’t a Very Good Plan

Buying in bulk is usually a smart money move if you can afford to do it. But as you come to the end of the pack, the last few batteries probably won’t be at full power. Try to stick with a 6-month supply or less unless you’re fine with wasting a few.

Shopping For Hearing Aid Batteries on The Web

Buying from the web can be a good thing. You can get some good deals. But some less scrupulous people sell batteries on the internet that are very close to the expiration date. Or worse, they are already passed. So buyer beware.
Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have an expiration date. You wouldn’t buy milk without checking the expiration. You should use the same amount of care with batteries. If you’re going to get the most out of your pack, make sure the date is well in the future. If the website doesn’t state an expiration date, message the vendor, or buy batteries directly from us. Only buy batteries from reputable sources.

Modern Hearing Aids Are Rechargeable

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