Do you feel like your hearing aid batteries won’t keep a charge as long as they should? Here are a few unexpected reasons that might occur.How long should hearing aid batteries last? Between 3 to 7 days is typical. That’s a really wide range. So wide, actually, that it’s unpredictable and puts you in a significant predicament. You might be on day 4 at the grocery store when unexpectedly, things go quiet and you’re unable to hear the cashier. 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 hear 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 that’s on. It’s more than a little inconvenient. You simply can’t tell how much battery power your hearing aids have left and it’s making you miss out on life. If your hearing aid batteries are draining too rapidly, there are several likely causes.
A Battery Can be Depleted by Moisture
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 sodium and toxins. On top of this, you may live in a rainy or humid climate where things are even wetter. This additional moisture can clog the air vent in your device, making it less efficient. It can even deplete the battery directly by interacting with the chemicals which create electricity. Here are some measures you can take to avoid moisture-caused battery drain:
- When you store your hearing aids, open the battery door
- Don’t keep your hearing aids in the bathroom, kitchen or other damp environments
- Don’t leave the batteries in when you’re storing them for several days
- Obtain a dehumidifier for your hearing aids
Advanced Hearing Aid Features Can Run Down Batteries
Advanced digital hearing aids help people hear a lot better than ones that you could get just a decade ago. But these extra features can cause batteries to drain faster if you’re not paying attention. Don’t quit using your favorite features. But just know that if you stream music for hours from your smartphone to your hearing aids, you’ll have to replace the battery sooner. Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these extra features can drain your battery.
Batteries Can be Affected by Altitude Changes
Your batteries can be drained if you go from low to high altitudes especially if they are already low on juice. When skiing, flying or climbing always brings some extra batteries.
Maybe The Batteries Aren’t 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”. It doesn’t mean you have a dead battery. In addition, sometimes an environmental change in humidity or altitude briefly causes the charge to drop and the low battery alert gets triggered. In order to stop the alarm, remove the batteries, and then put them back in. You may be able to get a few more hours or even days of battery life.
Handling Batteries Improperly
You should never remove the little tab from the battery until you’re ready to use it. Avoid getting dirt and skin oil on your hearing aid by cleansing your hands before touching them. Hearing aid batteries should not be frozen. This technique 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 quicker if you make these basic handling mistakes.
Buying a Year’s Supply of Batteries Isn’t a Good Idea
Buying in bulk is often a smart money decision when you can afford to do it. But as you come to the end of the pack, the last several batteries probably won’t be at full power. Try to stick with a 6-month supply or less unless you’re fine with the waste.
Shopping For Hearing Aid Batteries on The Web
It’s not an over-all criticism of buying things on the internet. There are some really good deals out in cyberspace. But some less honest people sell batteries on the internet that are very close to the expiration date. Or worse, they are already passed. So you need to be careful.
Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have a date they will expire. You shouldn’t buy milk without checking the expiration. You need to do that with batteries too. Make 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, send the online vendor a message, or purchase batteries from us. Be sure you know and trust the seller.
Modern Hearing Aids Are Rechargeable
Hearing aids may drain too rapidly for numerous reasons. But you can get more life out of your batteries by taking some precautions. You might also think about rechargeable hearing aids if you’re going to buy a new set. You put them on a charger each night for a full charge the next day. The rechargeable batteries only need to be changed every few years.
