Do you feel as if your hearing aid batteries won’t keep a charge as long as they should? Here are some surprising reasons that could occur. What is the average length of time that your hearing aid batteries should keep a charge? The typical hearing aid battery should last anywhere from 3 to 7 days. That’s a very wide range. As a matter of fact, it’s so wide that it probably can’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 all of a sudden you can’t hear the show your that’s on. It’s more than a little inconvenient. You just 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 dying too rapidly, there are several likely causes.
A Battery Can be Drained by Moisture
There aren’t very many species that produce moisture through their skin but humans do. We do it to cool down. We do it to get rid of excess toxins or sodium in the blood. In addition, you may live in a rainy or humid climate where things get even wetter. The air vent in your hearing aid can get clogged by this extra moisture and it will be less effective. Moisture can also interact with the chemicals of the battery causing it to deplete faster. You can prevent moisture-related battery drainage with these measures:
- A dehumidifier for your hearing aid is beneficial
- Before you store your hearing aids, open the battery door
- Moist conditions, like the kitchen or bathroom aren’t a good place to keep your hearing aids
- Don’t leave the batteries in when you’re storing them for a number of days
Batteries Can be Depleted by Advanced Hearing Aid Functions
Current digital hearing aids help people hear so much better than ones that came out just 10 years ago. But these extra features can cause batteries to run down faster if you’re not keeping an eye on them. You can still use your favorite features. But keep in mind, you will need to change the battery sooner if you are streaming music from your phone for hours. Your battery can be depleted by any of the advanced features, like multichannel, Bluetooth, noise cancellation, and tinnitus relief.
Altitude Changes Can Affect Batteries Too
Your batteries can be drained if you go from low to high altitudes specifically if they are already low on juice. When skiing, flying or climbing always takes some extra batteries.
It’s Possible That The Batteries Aren’t Really Low
Some models will give you a warning when the battery starts to get too low. As a general rule, these alerts are giving you a “heads up”. It doesn’t mean you have a depleted battery. Also, the charge can sometimes dip temporarily due to altitude or environmental 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 might be able to get a few more hours or possibly even days of battery life.
Handling Batteries Improperly
You should not remove the little tab from the battery until you’re ready to use it. Make sure you wash your hands before handling your hearing aids or batteries to protect against getting hand oil or dirt on them. Don’t ever freeze hearing aid batteries. It doesn’t increase their life as it might with other kinds of batteries. Basic handling mistakes such as these can make hearing aid batteries drain more quickly.
It’s Not a Good Plan to Buy a Year’s Supply of Batteries
Buying in bulk is typically a smart money move if you can afford to do it. But the last few batteries in the pack probably won’t have full power. Unless you don’t mind wasting a few, try to stick to a six month supply.
Buying Hearing Aid Batteries on The Web
Shopping online can be a good thing. There are some pretty good deals out in cyberspace. But some batteries that you can find on the internet are being sold by less honest individuals and are near their expiration date. Or even worse, they are already passed. So buyer beware.
Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have a date they will expire. If you were going to buy milk, you would check the expiration date. You should do that with batteries too. 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 purchase batteries directly from us. Make sure you know and trust the seller.
Current Hearing Aids Are Rechargeable
Hearing aids might drain too rapidly for numerous reasons. But by taking some precautions you can get more energy from each battery. If you’re in the market for a new set of hearing aids, you might decide on a rechargeable model. You dock them on a charger each night for a full day of hearing the next day. The rechargeable batteries only need to be changed every few years.
