Do you feel like your hearing aid batteries are not keeping a charge as long as they should? Here are a few surprising reasons that might occur.What is the average amount of time that your hearing aid batteries should stay charged? The ordinary hearing aid battery should last between 3 and 7 days. That range is pretty wide. So wide, actually, that it’s unpredictable and puts you in a significant predicament. Things could 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 enjoying a conversation with friends when you unexpectedly feel very alone because you can’t participate because you can’t hear. Sometimes the batteries don’t even make that 3 day mark. 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’re missing out on life because you’re not sure how much battery power you have left in your hearing aids. Here are the likely culprits if your hearing aid batteries die too soon.
Moisture Can Deplete a Battery
There aren’t many species that produce moisture through their skin but humans do. We do it to cool down. It’s the body’s way of ridding the blood of toxins and sodium. You may also live in a climate that is humid and moist. This excess moisture can clog the air vent in your device, making it less efficient. Moisture can also mix with the chemicals of the battery causing it to deplete faster. Here are some steps you can take to prevent moisture-caused battery drain:
- Don’t keep your hearing aids in the bathroom, kitchen or other moist environments
- Before you store your hearing aids, open the battery door
- Don’t leave the batteries in when you’re storing them for a number of days
- A dehumidifier for your hearing aid is recommended
Advanced Hearing Aid Features Can Drain Batteries
You get a much better hearing aid today than you did even 10 years ago. But if you’re not paying attention, these advanced functions can cause faster battery drain. Don’t stop using your favorite features. But remember, you will need to replace the battery sooner if you are streaming music from your phone for hours. Your battery can be drained by any of the advanced functions, like multichannel, Bluetooth, noise cancellation, and tinnitus relief.
Batteries Can be Impacted by Altitude Changes
Going from a low to high altitude can sap your batteries, specifically if they’re on their older. When flying, skiing or climbing always brings some extra batteries.
Are The Batteries Really Low?
Some models will give you a warning when the battery begins to get too low. These warnings are, under normal circumstances, a “heads up”. It doesn’t mean you have a depleted battery. Moreover, sometimes an environmental change in humidity or altitude briefly causes the charge to dip and the low battery alarm gets activated. In order to stop the alarm, take the batteries out, and then put them back in. You may be able to get a few more hours or possibly even days of battery life.
Handling Batteries Improperly
Wait until you’re about to use your hearing aid to remove the tab from the battery. Make sure you wash your hands before handling your hearing aids or batteries to avoid getting hand oil or dirt on them. Hearing aid batteries should never be frozen. It doesn’t extend their life as it could with other kinds of batteries. Hearing aid batteries might lose battery power faster if you make these basic handling mistakes.
It isn’t a Good Idea to Purchase a Year’s Supply of Batteries
Buying in bulk is usually a smart money decision if you can afford to do it. But as you come to the end of the pack, the last several batteries most likely won’t be at full power. Unless you don’t mind wasting a few, try to stay with a six month supply.
Purchasing Hearing Aid Batteries on The Web
Buying online can be a good thing. There are some pretty great deals out in cyberspace. But some less scrupulous people sell batteries online that are very near to the expiration date. They might even be beyond their expiration date. So buyer beware.
There’s an expiration date on both zinc and alkaline batteries. If you were going to buy milk, you would look at the expiration date. You have to use the same amount of caution with batteries. If you want to get the most from your pack, make sure the date is well in the future. It’s probably a smart idea to message the vendor if you don’t see an expiration date or better yet, come see us for your battery needs. Only purchase batteries from reliable sources.
