Do you feel as if your hearing aid batteries are not keeping a charge as long as they should? The reasons for this can be sometimes unexpected.How long should hearing aid batteries keep a charge? Anywhere from 3 to 7 days is typical. That range is pretty wide. As a matter of fact, it’s so wide that it probably doesn’t help you predict what should be taking place with your hearing aid. Things could suddenly go quiet when you’re trying to hear the cashier at the grocery store after 4 days of battery power. Or maybe on day 5, you’re enjoying a conversation with friends when you suddenly feel very alone because you can’t hear what anyone is saying. Sometimes the batteries don’t even make 3 days. Like when you’re watching TV on day 2 and all of a sudden you can’t hear the show your watching. 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 dying too rapidly, there are several likely culprits.

Moisture Can Deplete a Battery

There aren’t many species that produce moisture through their skin but humans do. We do it to cool off. We do it to get rid of excess toxins or sodium in the blood. You may also live in a climate that’s moist and humid. The air vent in your hearing aid can get clogged by this added moisture and it will be less reliable. Moisture can also mix with the chemicals of the battery causing it to deplete faster. You can prevent moisture-related battery drainage with these steps:

  • Don’t leave the batteries in if you’re storing them for a few days
  • Don’t keep your hearing aids in the bathroom, kitchen or other moist conditions
  • Get a dehumidifier for your hearing aids
  • Open the battery door when you store the hearing aids

Batteries Can be Drained by Advanced Hearing Aid Features

Current digital hearing aids help people hear a lot better than ones that you could get just ten years ago. But these extra features can cause batteries to run down faster if you’re not paying attention. Don’t avoid using your favorite features. But just know that if you stream music all day from your mobile device to your hearing aids, you’ll have to change the battery sooner. Your battery can be depleted by any of the advanced functions, like multichannel, Bluetooth, noise cancellation, and tinnitus relief.

Altitude Changes Can Impact Batteries Too

Your batteries can be sapped out if you go from low to high altitudes especially if they are already low on juice. Bring some spare batteries if you are going on a plane or high up into the mountains.

It’s Possible That The Batteries Aren’t Really Low

Some models will give you a warning when the battery starts to get too low. As a general rule, these alerts are giving you a “heads up”. It doesn’t mean you have a depleted battery. Furthermore, the charge can sometimes drop briefly due to environmental or altitude changes and that can trigger a false low battery warning. Remove the hearing aids and reset them to end the alarm. The battery might last several more hours or even days.

Handling Batteries Improperly

You should never take out the little tab from the battery before you’re ready to use it. Avoid getting skin oil and dirt on your hearing aid by washing your hands before touching them. Never freeze hearing aid batteries. It doesn’t extend their life as it might with other types of batteries. Hearing aid batteries may lose battery power more quickly if you make these basic handling errors.

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

If you can afford to do it, purchasing in bulk can be a smart plan. But as you get toward the end of the pack, the last few batteries probably won’t be at full power. Try to stay with a 6-month supply or less unless you’re okay with wasting a few.

Shopping For Hearing Aid Batteries Online

It’s not a general critique of purchasing stuff on the internet. You can get some great deals. But some less scrupulous people sell batteries online that are very near to the expiration date. Or even worse, it has already passed. So you need to be cautious.
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 should do that with batteries also. If you want to get the most out of your pack, be sure the date is well in the future. If the website doesn’t state an expiration date, send the online vendor a message, or buy batteries directly from us. Be sure you know and trust the seller.

Now You Can Get Rechargeable Hearing Aids

Hearing aids may drain too rapidly for numerous reasons. But by taking little precautions you can get more energy from each battery. If you’re looking to buy a new set of hearing aids, you might consider a rechargeable model. You dock them on a charger every night for a full day of hearing the next day. The rechargeable batteries only have to be replaced every few years.
