Do you feel like your hearing aid batteries are not keeping a charge as long as they should? The reasons for this can be sometimes unexpected.What is the average amount of time that your hearing aid batteries should stay charged? Between 3 to 7 days is typical. That’s a very wide range. Actually, 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 enjoying a call with friends when all of a sudden you find yourself feeling really alone because you can no longer follow the conversation. Now, you’re watching TV. All of a sudden you can’t hear the news. Wait, it’s only day 2. Yes, sometimes they even die before that 3-day mark. It’s not just inconvenient. You’re missing out on life because you don’t know how much juice you have left in your hearing aids. If your hearing aid batteries are dying too fast, there are a few likely culprits.

A Battery Can be Depleted by Moisture

There aren’t many species that release moisture through their skin but humans do. We do it to cool off. We do it to get rid of excess toxins or sodium in the blood. In addition, you may live in a humid or rainy climate where things get even wetter. This excess 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 avoid moisture-caused battery drain:

  • Obtain a dehumidifier for your hearing aids
  • Moist conditions, like the kitchen or bathroom aren’t a good place to keep your hearing aids
  • Before you store your hearing aids, open the battery door
  • Don’t leave the batteries in when you’re storing them for several days

Advanced Hearing Aid Features Can Drain Batteries

You get a much better hearing aid nowadays than you did even 10 years ago. But if you’re not keeping your eye on them, these advanced features can cause faster battery drain. Don’t stop using your favorite features. But be aware that if you stream music all day from your smartphone to your hearing aids, you’ll have to change the battery sooner. Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these extra features can deplete your battery.

Batteries Can be Affected by Altitude Changes

Your batteries can be sapped out if you go from low to high altitudes specifically if they are already low on juice. Bring some extra batteries if you are going on a plane or high up into the mountains.

It’s Possible That The Batteries Aren’t Really Low

Some models will give you a warning when the battery begins to get too low. Generally speaking, these alerts are giving you a “heads up”. They’re not actually saying the battery is depleted. Also, the charge can at times drop briefly due to environmental or altitude changes and that can cause a false low battery warning. In order to end the alarm, remove the batteries, and then put them back in. You may be able to get a few more hours or possibly even days of battery life.

Handling Batteries Improperly

Wait until you’re ready to use your hearing aid to remove the tab from the battery. Avoid getting dirt and skin oil on your hearing aid by cleaning your hands before handling them. Hearing aid batteries should never be frozen. It doesn’t lengthen their life as it might with other types of batteries. Hearing aid batteries may lose battery power quicker if you make these basic handling mistakes.

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

When you can afford to do it, purchasing in bulk can be a smart idea. But the last few batteries in the pack most likely won’t have full power. Unless you’re fine with wasting a few, try to stick to a six month supply.

Shopping For Hearing Aid Batteries on The Web

Shopping from the web can be a good thing. There are some pretty great deals out in cyberspace. But some batteries that you can find online are being sold by less honest individuals and are near their expiration date. Or worse, they are 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 should do that with batteries also. Be sure that the date is well in the future so that you can get the most use out of the pack. If the website doesn’t mention an expiration date, message the vendor, or buy batteries from us. Be sure you know and trust the seller.

Current Hearing Aids Are Rechargeable

Hearing aids might drain too quickly for a number of reasons. But by taking some precautions you can get more energy out of each battery. If you’re looking to buy a new pair of hearing aids, you might consider a rechargeable model. If you charge them while you sleep, you get a full day of hearing the next day. And you only have to replace them every few years.
