Do your hearing aid batteries seem to drain quicker than they ought to? Here are some unexpected reasons that may happen.
So how long should the charge on my hearing aid battery go? From 3 to 7 days is the typical time-frame for charge to last.
That range is fairly wide. But it’s so wide that it’s unpredictable and may leave you in trouble.
You could be on day 4 at the supermarket store. Suddenly, things get quiet. The cashier is speaking to you but you can’t hear what they are saying.
Or it’s day 5. You’re enjoying a night out with friends. All of a sudden, you can’t follow the discussion and it’s leaving you feeling rather alone.
Now, you’re attending your grandchild’s school play. And the kid’s singing goes quiet. Wait, it’s only day 2. Yes, sometimes they even die before the 3rd day.
It’s not simply inconvenient. You’re losing out on life because you’re not sure how much power you have left in your hearing aids.
If your hearing aid batteries die too quickly, check out these seven possible causes.
Your Battery can be drained by moisture
Did you realize that human beings are one of the few species that release moisture through their skin? It’s a cooling system. You do it to eliminate extra sodium or toxins in the blood. Your battery may be exposed to even more moisture if you live in a humid or rainy setting.
This extra moisture can clog up the air vent in your device, making hearing aids less efficient. It can even kill the battery directly by interacting with the chemicals that generate electricity.
Here are a few steps you can take to avoid moisture-caused battery drain:
- Before you go to bed, open up the battery door
- If you’re storing your hearing aids for an extended time period, take out the batteries
- Don’t keep your hearing aids in the kitchen or bathroom
- A dehumidifier can be helpful
Sophisticated modern features are power intensive
Even 10 years ago, hearing aids were a lot less helpful for people with hearing loss than modern devices. But these added features can cause batteries to drain faster if you’re not paying attention.
Don’t stop using your favorite features. But just know that if you stream music all day from your smartphone to your hearing aids, you’ll need 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
Going from a low to high altitude can drain your batteries, especially if they’re on their last leg. When flying, skiing, or climbing remember to bring some spares.
Perhaps the batteries aren’t really drained
Many hearing aids will warn you when the batteries need to be changed. These warnings, as a general rule, aren’t telling you that your batteries are dead, they’re just a heads up. In addition, you may get a warning when the charge drops due to an altitude or humidity change.
Take the hearing aids out and reset them to stop the alarm. You may be able to get several more hours or even days from that battery.
Incorrect handling of batteries
Wait until you’re ready to use the battery before you pull off the protective tab. Always wash your hands before handling your hearing aids or batteries to avoid getting hand oil or dirt on them. Don’t ever freeze hearing aid batteries. This might extend the life of other batteries but it doesn’t work with hearing aid batteries.
Simple handling errors like these can make hearing aid batteries drain quickly.
Purchasing a year’s supply of batteries isn’t a good idea
It’s often a practical financial choice to buy in bulk. But you can anticipate that the last several batteries in the pack will drain faster. Try to limit yourself to a 6-month supply or less unless you’re fine with the waste.
internet battery vendors
We’re not saying it’s necessarily a bad idea to buy things on the internet. You can get some great deals. But some less scrupulous individuals will sell batteries on the internet that are very near to the expiration date. Or even worse, it has already passed.
Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have an expiration date. When you buy milk, you wouldn’t forget to check the expiration date. The same goes with batteries. Make sure that the date is well in the future to get the most usage out of the pack.
If the website doesn’t state an expiration date, message the seller, or purchase batteries at a pharmacy or hearing aid center where you can see it on the packaging. Make sure you check reviews to be certain you’re buying from a reputable source.
The batteries in hearing aids no longer drain quickly
There are several reasons that hearing aid batteries may drain quickly. But by taking little precautions you can get more energy from each battery. You might also consider rechargeable hearing aids if you’re shopping for a new pair. You dock these hearing aids on a charger each night for an entire day of hearing the next day. Every few years, you will need to change the rechargeable batteries.
