Do your hearing aid batteries seem to die quicker than they should? Here are a few surprising reasons that might occur.
How long should hearing aid batteries last? From 3 to 7 days is the standard time-frame for charge to last.
That range is pretty wide. But it’s so wide that it’s unpredictable and might leave you in trouble.
You could be on day 4 at the supermarket store. Out of the blue, you can’t hear anything. The cashier is talking to you but you don’t hear what they are saying.
Or, you’re out for lunch with friends on day 5. All of a sudden, you can’t follow the discussion and it’s leaving you feeling rather alone.
Perhaps you go to your grandchild’s school to watch a play. And the children’s singing goes quiet. Wait, it’s just day 2. Yes, sometimes they even die before the 3rd day.
It’s not only inconvenient. You have no clue how much juice is left and it’s causing you to miss out on life.
If your hearing aid batteries die too quickly, look to these seven possible causes.
Moisture can drain a battery
Producing moisture through our skin is one thing that human beings do that the majority of other species don’t. It’s a cooling mechanism. You do it to remove excess sodium or toxins in the blood. In addition, you might live in a rainy humid climate where things get even wetter.
This excess moisture can clog the air vent in your device, affecting the hearing aid’s efficiency. It can even drain the battery directly by interacting with the chemicals that produce electricity.
Avoid battery drain related to moisture with these steps:
- Get a dehumidifier
- Open the battery door before you store your hearing aids
- Don’t store your hearing aids in the bathroom or kitchen
- If you’re storing your hearing aids for a prolonged time period, remove the batteries
Advanced 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 when these sophisticated functions are in use, they can be a drain on battery power.
Don’t quit using your favorite features. But be aware that the battery will drain faster if you spend all day streaming music from your cellphone to your hearing aids.
Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these added functions can drain your battery.
Batteries can be affected by altitude changes
Going from a low to high altitude can sap your batteries, particularly if they’re on their last leg. Be certain that you bring some spares if you are in the mountains or on a plane.
Is the battery really drained?
Some hearing aids tell you when the battery is low. These warnings, as a general rule, aren’t telling you that your batteries are dead, they’re just a heads up. Additionally, you may get a warning when the charge drops due to an altitude or humidity change.
You can turn off the alarm by removing and resetting your hearing aid. There may be hours or even days of juice left.
Improper handling of batteries
You shouldn’t pull off the little tab from the battery before you’re ready to use it. Hand oil or dirt can be an issue for batteries so wash up before handling them. Keep your batteries out of the freezer. It doesn’t increase their life as it might with other kinds of batteries.
Hearing aids will drain faster if you mishandle them in these ways.
Buying a year’s supply of batteries isn’t a great idea
Buying in bulk is usually a smart money decision when you can afford to do it. But you can expect that the last few batteries in the pack won’t last as long. Try to limit yourself to a 6-month supply or less unless you’re fine with the waste.
Buying hearing aid batteries from the internet
We’re not suggesting it’s necessarily a bad idea to purchase things on the internet. You can get some great deals. But you will also find some less honest sellers who will sell batteries that are close to or even past their expiration date.
Most types of batteries, including hearing aid batteries, have expiration dates. When you purchase milk, you wouldn’t forget to check the date it expires. The same goes with batteries. Make sure that the date is far enough in the future to get the most usage out of the pack.
If you purchase your batteries at a hearing aid store or pharmacy, the expiration date will be on the labeling, but if you are going to shop on the internet be sure the seller specifies when the batteries will expire. Make sure you look for reviews to be certain you’re purchasing from a reliable source.
Hearing aid batteries drain quickly no longer
Hearing aid batteries may drain faster for several reasons. But you can get more power from each battery by taking small precautions. And if you’re thinking of an upgrade, think about rechargeable hearing aids. You put these hearing aids on a charger each night for a full day of hearing the next day. The rechargeable batteries only have to be replaced every few years.
