Do you feel as if your hearing aid batteries are not keeping a charge as long as they should? The reasons for this can be sometimes surprising. What is the average period of time that your hearing aid batteries should keep a charge? Anywhere from 3 to 7 days is typical. That range is fairly wide. So wide, in fact, that it’s unpredictable and leaves you in a serious predicament. Things might suddenly get 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. Sometimes 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 your hearing aids have left and it’s causing you to miss out on life. Here are the most likely culprits if your hearing aid batteries die too soon.
A Battery Can be Depleted by Moisture
Did you know that humans are one of the few species that produce moisture through their skin? We do it to cool off. We do it to get rid of excess toxins or sodium in the blood. On top of this, you might live in a humid or rainy climate where things are even more moist. The air vent in your hearing aid can get clogged by this added moisture and it will be less efficient. Moisture can also interact with the chemicals of the battery causing it to deplete faster. You can avoid moisture-related battery drainage with these steps:
- Don’t leave the batteries in when you’re storing them for several days
- Moist conditions, like the kitchen or bathroom are not a good place to keep your hearing aids
- When you store your hearing aids, open the battery door
- Obtain a dehumidifier for your hearing aids
Batteries Can be Depleted by Advanced Hearing Aid Functions
You get a much better hearing aid now than you did even a decade ago. But if you’re not keeping your eye on them, these advanced features can cause faster battery drain. You can still use your favorite features. But keep in mind, you will need to replace the battery sooner if you are streaming music from your phone for hours. Your battery can be depleted by any of the advanced functions, like Bluetooth, multichannel, 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 flying, skiing or climbing always takes some spare batteries.
Are The Batteries Really Low?
Some hearing aids tell you when the battery is low. These warnings are, under normal circumstances, a “heads up”. It doesn’t mean you have a dead battery. Also, the charge can occasionally drop temporarily due to altitude or environmental changes and that can activate a false low battery warning. Take the hearing aids out and reset them to stop the alarm. The battery may last several more hours or even days.
Handling Batteries Improperly
Wait until you’re about to use your hearing aid to pull the tab from the battery. Always 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. This technique may increase the life of some types of battery but it doesn’t work with hearing aid batteries. Simple handling errors like these can make hearing aid batteries drain more quickly.
Purchasing a Year’s Supply of Batteries Isn’t a Very Good Plan
Buying in bulk is often a smart money move if you can afford to do it. But the last few batteries in the pack most likely 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
It’s not a general critique of purchasing stuff on the internet. There are some really good deals out in cyberspace. But some less honest people will sell batteries online 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 an expiration date. If you were going to buy milk, you would look at the expiration date. You should use the same amount of caution with batteries. 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 state an expiration date, send the online vendor a message, or purchase batteries directly from us. Be sure you know and trust the seller.
Current Hearing Aids Are Rechargeable
There are a number of reasons that hearing batteries might drain quickly. But you can get more life out of your batteries by taking some precautions. You may also think about rechargeable hearing aids if you’re going to buy a new set. If you charge them at night, you get a full day of power the next day. And you only need to change them every few years.
