HEARING TIPS

“Man

Does it seem like your hearing aid batteries lose their charge too fast? The reasons for this are sometimes unexpected.How long should hearing aid batteries last? The normal hearing aid battery should last anywhere from 3 to 7 days. That’s a very wide range. In fact, it’s so wide that it probably doesn’t help you predict what should be going on with your hearing aid. You may be on day 4 at the grocery store when out of the blue, things go quiet and you’re unable to hear the cashier. Or maybe on day 5, you’re having an enjoyable conversation with friends when you suddenly feel really alone because you can’t hear what anyone is saying. Now, you’re watching TV. You can no longer hear the news. Hold on, it’s only day 2. Yes, sometimes they even die before that 3-day mark. It’s more than a little inconvenient. You’re missing out on life because you’re not sure how much battery power is left in your hearing aids. If your hearing aid batteries are draining too rapidly, there are a small number of likely culprits.

A Battery Can be Depleted by Moisture

Did you know that humans are one of the few species that produce moisture through their skin? It’s a cooling method. It’s the body’s way of ridding the blood of sodium and toxins. You might also live in a climate that’s moist and humid. This additional moisture can clog the air vent in your device, making it less reliable. Moisture can also mix with the chemicals of the battery causing it to deplete faster. You can avoid moisture-related battery drainage with these steps:

  • if your storing them for several days or more, remove the batteries
  • A dehumidifier for your hearing aid is helpful
  • When you store your hearing aids, open the battery door
  • Moist environments, like the kitchen or bathroom are not a good place to keep your hearing aids

Batteries Can be Drained by Advanced Hearing Aid Functions

Advanced digital hearing aids help people hear a lot better than ones that came out just ten years ago. But these extra features can cause batteries to run down faster if you’re not paying attention. You can still use your favorite features. But just know that if you stream music for hours from your smartphone to your hearing aids, you’ll have to replace the battery sooner. Bluetooth, multichannel, tinnitus relief, noise canceling — all of these extra features can deplete your battery.

Altitude Changes Can Affect Batteries Too

Moving from a low to high altitude can deplete your batteries, especially if they’re on their older. Take some extra batteries if you are going on a plane or high up into the mountains.

Maybe The Batteries Aren’t Really Low

Some hearing aids tell you when the battery is running low. As a general rule, these alerts are giving you a “heads up”. They’re not actually saying the battery is dead. Additionally, the charge can sometimes drop briefly due to altitude or environmental changes and that can trigger a false low battery warning. In order to end the alarm, take the batteries out, and then put them back in. You might be able to get a few more hours or possibly even days of battery life.

Improper Handling of Batteries

Wait until you’re ready to use your hearing aid to pull the tab from the battery. Always wash your hands before touching your hearing aids or batteries to protect against getting hand oil or dirt on them. Hearing aid batteries should not be frozen. It doesn’t extend their life as it might with other types of batteries. Basic handling errors such as these can make hearing aid batteries drain faster.

Purchasing a Year’s Supply of Batteries Isn’t a Very Good Idea

When you can afford to do it, purchasing in bulk can be a smart idea. But the last few batteries in the pack most likely won’t have full power. Try to stay with a 6-month supply or less unless you’re okay with the waste.

Buying Hearing Aid Batteries on The Web

Shopping online can be a good thing. You can get some good deals. But some batteries that can be found online are being sold by less honest individuals and are close to their expiration date. They may even be beyond their expiration date. So you need to be careful.
There’s an expiration date on both alkaline and zinc batteries. You wouldn’t buy milk without checking the expiration. You have to use the same amount of caution with batteries. If you’re going to get the most out of your pack, be sure the date is well in the future. It’s probably a good idea to message the vendor if you don’t see an expiration date or better yet, come see us for your battery needs. Make sure you know and trust the seller.
