Do you feel like your hearing aid batteries won’t keep a charge as long as they should? Here are a few surprising reasons that might happen.How long should hearing aid batteries keep a charge? The typical hearing aid battery lasts between 3 and 7 days. That range is pretty wide. Actually, it’s so wide that it probably won’t help you predict what should be going on with your hearing aid. Things might suddenly go quiet when you’re trying to hear the cashier at the supermarket after 4 days of battery power. Or maybe on day 5, you’re having an enjoyable conversation with friends when you unexpectedly feel very alone because you can’t hear what anyone is saying. Now, you’re watching the TV. You can no longer hear the news. Hold on, it’s only day 2. Yes, occasionally they even die before that 3-day mark. It’s more than a little inconvenient. You’re missing out on life because you’re not sure how much juice is left in your hearing aids. If your hearing aid batteries are dying too fast, there are a small number of likely causes.
A Battery Can be Drained by Moisture
Did you know that humans are one of the few species that release moisture through their skin? It’s a cooling mechanism. We do it to clear out excess toxins or sodium in the blood. Moreover, you might live in a humid or rainy climate where things are even more moist. This extra moisture can clog the air vent in your device, making it less reliable. Moisture can also mix with the chemicals of the battery causing it to drain faster. Here are some steps you can take to prevent moisture-caused battery drain:
- Moist conditions, like the kitchen or bathroom are not a good place to keep your hearing aids
- Before you store your hearing aids, open the battery door
- Obtain a dehumidifier for your hearing aids
- Don’t leave the batteries in if you’re storing them for several days
Batteries Can be Depleted by Advanced Hearing Aid Features
You get a much better hearing aid now than you did even ten years ago. But these extra features can cause batteries to run down faster if you’re not paying attention. Don’t avoid using your favorite features. But bear in mind, you will have to change the battery sooner if you are streaming music from your phone for hours. Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these added functions can drain 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. When flying, skiing or climbing always takes some spare batteries.
Maybe The Batteries Aren’t Really Low
Some models will give you an alert when the battery starts to get too low. Generally speaking, these warnings are giving you a “heads up”. They’re not telling you the battery is depleted. Moreover, sometimes an environmental change in humidity or altitude briefly causes the charge to dip and the low battery alert gets triggered. In order to end the alarm, remove the batteries, and then put them back in. The battery might last a few more hours or even days.
Handling Batteries Improperly
You should not take out the little tab from the battery until you’re ready to use it. Refrain from getting skin oil and dirt on your hearing aid by washing your hands before touching them. Hearing aid batteries should never be frozen. This strategy might extend the life of some kinds of battery but it doesn’t work with hearing aid batteries. Basic handling errors like these can make hearing aid batteries drain more quickly.
Getting a Year’s Supply of Batteries Isn’t a Good Idea
Buying in bulk is typically a smart money move if you can afford to do it. But as you get toward the end of the pack, the last few batteries probably won’t last as long. Try to stay with a 6-month supply or less unless you’re okay with wasting a few.
Purchasing Hearing Aid Batteries on The Internet
This isn’t a broad critique of purchasing stuff on the web. You can get some good deals. But some less scrupulous people will sell batteries on the internet that are very close to the expiration date. They may even be past their expiration date. So you need to be careful.
There’s an expiration date on both alkaline and zinc batteries. If you were going to buy milk, you would check the expiration date. You have to use the same amount of caution with batteries. Be sure that the date is not close to the expiration so that you can get the most use out of the pack. If the website doesn’t specify an expiration date, message the vendor, or buy batteries directly from us. Be sure you know and trust the seller.
Now You Can Get Rechargeable Hearing Aids
Hearing aids could drain too quickly for a number of reasons. But you can get more life from your batteries by taking some precautions. If you’re looking to buy a new set of hearing aids, you might decide on a rechargeable model. If you charge them at night, you get a full day of power the next day. And you only have to change them every few years.
