Does it seem as if your hearing aid batteries drain way too fast? The reasons for this can be sometimes surprising.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 go 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 unexpectedly you find yourself feeling really alone because you can no longer hear the conversation. Occasionally 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 just can’t tell how much battery power you have left in your hearing aids and it’s causing you to miss out on life. If your hearing aid batteries are dying too quickly, there are a few likely causes.
Moisture Can Drain a Battery
Did you realize that humans are one of the few species that release moisture through their skin? It’s a cooling mechanism. It’s the body’s way of ridding the blood of toxins and sodium. In addition, you might live in a humid or rainy climate where things get even more moist. The air vent in your hearing aid can get clogged by this added moisture and it will be less effective. It can even deplete the battery directly by interacting with the chemicals that create electricity. Here are a few steps you can take to prevent moisture-caused battery drain:
- Moist environments, like the kitchen or bathroom are not a good place to keep your hearing aids
- Don’t leave the batteries in when you’re storing them for a few days
- Open the battery door when you store the hearing aids
- A dehumidifier for your hearing aid is recommended
Advanced Hearing Aid Functions Can Deplete Batteries
Modern 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 functions can cause faster battery drain. Don’t avoid using your favorite features. But keep in mind, you will have to switch out the battery sooner if you are streaming music from your phone all day. Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these added functions can drain your battery.
Batteries Can be Affected by Altitude Changes
Your batteries can be drained if you go from low to high altitudes specifically if they are already low on juice. When flying, skiing or climbing always takes some extra batteries.
Perhaps The Batteries Aren’t Really Low
Some models will give you a warning when the battery begins to get too low. These warnings are, ordinarily, a “heads up”. They’re not telling you the battery is dead. Also, the charge can occasionally drop briefly due to altitude or environmental changes and that can activate a false low battery warning. Remove the hearing aids and reset them to stop the alarm. You might be able to get a few more hours or even days out of that battery.
Improper Handling of Batteries
Wait until you’re ready to use your hearing aid to remove the tab from the battery. Steer clear of getting skin oil and dirt on your hearing aid by cleansing 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 might lose battery power more quickly if you make these simple handling errors.
Buying a Year’s Supply of Batteries Isn’t a Good Plan
Buying in bulk is typically a smart money move when you can afford to do it. But as you come to the end of the pack, the last few batteries likely won’t be at full power. Try to stay with a 6-month supply or less unless you’re fine with the waste.
Purchasing Hearing Aid Batteries on The Web
Shopping from the web can be a good thing. You can get some great deals. 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 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 also. Make 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 state an expiration date, send the online vendor a message, or purchase batteries from us. Only buy batteries from reliable sources.
Current Hearing Aids Are Rechargeable
Hearing aids may drain too rapidly for numerous reasons. But by taking some precautions you can get more life out of each battery. You may also consider rechargeable hearing aids if you’re in the market for a new set. You dock them on a charger each night for a full charge the next day. The rechargeable batteries only need to be replaced every few years.
