Man touching hearing aids that stopped working because the batteries drained.

Do you feel as if your hearing aid batteries won’t keep a charge as long as they should? The reasons for this are sometimes unexpected.How long should hearing aid batteries keep a charge? Between 3 to 7 days is typical. That range is pretty wide. In fact, it’s so wide that it probably can’t help you predict what should be happening with your hearing aid. You might be on day 4 at the grocery store when all of a sudden, things get quiet and you can’t hear the cashier. Or perhaps on day 5, you’re having an enjoyable conversation with friends when you unexpectedly feel very alone because you can’t participate because you can’t hear. Now, you’re watching the TV. All of a sudden you can’t hear the news. Hold on, it’s only day 2. Yes, sometimes they even drain before that 3-day mark. It’s more than a little inconvenient. You just can’t tell how much battery power your hearing aids have left and it’s making you miss out on life. If your hearing aid batteries are draining too quickly, there are a few likely causes.

A Battery Can be Depleted by Moisture

Did you realize that humans are one of the few species that release moisture through their skin? We do it to cool down. We do it to clear out excess toxins or sodium in the blood. You might also live in a climate that is moist and humid. This extra 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. You can avoid moisture-related battery drainage with these measures:

  • 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 helpful
  • Don’t keep your hearing aids in the bathroom, kitchen or other moist environments

Advanced Hearing Aid Features Can Drain Batteries

Advanced digital hearing aids help people hear a lot better than ones that came out just ten years ago. But if you’re not paying attention, these advanced functions can cause faster battery drain. Don’t avoid 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. Your battery can be drained by any of the advanced functions, like Bluetooth, multichannel, noise cancellation, and tinnitus relief.

Batteries Can be Affected by Altitude Changes

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

Are The Batteries Really Low?

Some hearing aids tell you when the battery is running low. Generally, these warnings are giving you a “heads up”. They’re not telling you the battery is dead. Moreover, sometimes an environmental change in humidity or altitude temporarily causes the charge to dip and the low battery alert gets activated. In order to end the alarm, take the batteries out, and then put them back in. The battery might last several more hours or even days.

Improper Handling of Batteries

Wait until you’re about to use your hearing aid to remove the tab from the battery. Make sure you wash your hands before touching your hearing aids or batteries to protect against getting hand oil or dirt on them. Hearing aid batteries should never be frozen. This trick may increase the life of some types of battery but it doesn’t work with hearing aid batteries. Basic handling mistakes like these can cause hearing aid batteries to drain more quickly.

Getting a Year’s Supply of Batteries Isn’t a Good Plan

When you can afford to do it, purchasing in bulk can be a smart plan. But as you come to the end of the pack, the last several batteries most likely won’t last as long. Try to stick with a 6-month supply or less unless you’re okay with the waste.

Purchasing Hearing Aid Batteries on The Web

Shopping from the web can be a good thing. There are some really great deals out in cyberspace. But some batteries that can be found online are being sold by less honest individuals and are close to their expiration date. Or worse, they are already passed. So buyer beware.
There’s an expiration date on both alkaline and zinc 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. Be sure that the date is well in the future so that you can get the most use out of the pack. 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. Be sure you know and trust the seller.

Current Hearing Aids Are Rechargeable

There are several reasons that hearing batteries could drain rapidly. But by taking some precautions you can get more life from each battery. You may also consider rechargeable hearing aids if you’re going to buy a new set. You put them on a charger every night for a full charge the next day. The rechargeable batteries only have to be replaced every few years.
