Does it seem as if your hearing aid batteries drain way too fast? The reasons for this are sometimes surprising.What is the average length of time that your hearing aid batteries should stay charged? Between 3 to 7 days is normal. That’s a very wide range. So wide, actually, that it’s unpredictable and puts you in a serious predicament. 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 maybe on day 5, you’re enjoying a conversation with friends when you suddenly 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. Wait, 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. Here are the most likely culprits if your hearing aid batteries drain quickly.

A Battery Can be Depleted by Moisture

There aren’t very many species that release moisture through their skin but humans do. It’s a cooling mechanism. We do it to get rid of excess sodium or toxins 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 effective. Moisture can also interact with the chemicals of the battery causing it to deplete faster. You can prevent moisture-related battery drainage with these measures:

  • Open the battery door before storing the hearing aids
  • Don’t leave the batteries in when you’re storing them for several days
  • A dehumidifier for your hearing aid is recommended
  • Don’t keep your hearing aids in the bathroom, kitchen or other moist environments

Batteries Can be Drained by Advanced Hearing Aid Features

You get a much better hearing aid nowadays than you did even 10 years ago. But if you’re not keeping your eye on them, these advanced features can cause faster battery drain. Don’t stop using your favorite features. But keep in mind, you will need to change the battery sooner if you are streaming music from your phone for hours. Bluetooth, multichannel, tinnitus relief, noise canceling — all of these extra features can deplete your battery.

Batteries Can be Impacted by Altitude Changes

Moving from a low to high altitude can sap your batteries, specifically if they’re on their last leg. When flying, skiing or climbing always takes some extra batteries.

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

Some hearing aids let you know when the battery is running low. Generally speaking, these alerts are giving you a “heads up”. They’re not actually saying the battery is dead. Moreover, sometimes an environmental change in humidity or altitude temporarily causes the charge to dip and the low battery alarm gets activated. Remove the hearing aids and reset them to end the alarm. You might be able to get several more hours or even days out of that battery.

Improper Handling of Batteries

You should not take out the little tab from the battery before you’re ready to use it. Always wash your hands before handling your hearing aids or batteries to avoid getting dirt or hand oil on them. Don’t ever freeze hearing aid batteries. This technique might extend the life of some kinds of battery but it doesn’t work with hearing aid batteries. Basic handling mistakes such as these can cause hearing aid batteries to drain more quickly.

It isn’t a Good Plan to Purchase a Year’s Supply of Batteries

Buying in bulk is typically a smart money move if you can afford to do it. But the last few batteries in the pack probably won’t have full power. Try to stay with a 6-month supply or less unless you’re okay with wasting a few.

Purchasing Hearing Aid Batteries on The Web

This isn’t an over-all critique of purchasing stuff on the internet. You can get some good deals. But some batteries that can be found online are being sold by less honest people and are near their expiration date. Or even worse, they are already passed. So you need to be cautious.
Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have a date they will expire. You wouldn’t buy milk without looking at the expiration. You should do that with batteries too. Be certain that the date is well in the future to get the most use out of the pack. If the website doesn’t mention an expiration date, message the vendor, or purchase batteries from us. Only purchase batteries from reputable sources.

Modern Hearing Aids Are Rechargeable

There are several reasons that hearing batteries may drain rapidly. But you can get more power out of your batteries by taking some precautions. You might also consider rechargeable hearing aids if you’re in the market for a new set. You put 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.
