Does it seem as if your hearing aid batteries lose their charge too fast? Here are some surprising reasons that might occur.How long should hearing aid batteries last? Between 3 to 7 days is standard. That range is fairly wide. As a matter of fact, it’s so wide that it probably doesn’t help you predict what should be happening with your hearing aid. Things might suddenly go quiet when you’re trying to hear the cashier at the grocery store after 4 days of battery power. Or it’s day 5 and you’re enjoying a call with friends when unexpectedly you find yourself feeling very alone because you can no longer hear the conversation. Now, you’re watching the TV. You can no longer hear the news. Hold on, it’s only day 2. Yes, sometimes they even drain before that 3-day mark. It isn’t just annoying. 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 fast, there are several likely causes.
Moisture Can Drain a Battery
There aren’t very many species that produce moisture through their skin but humans do. We do it to cool down. We do it to clear out excess sodium or toxins in the blood. On top of this, you might live in a rainy or humid climate where things are even more moist. This excess moisture can clog the air vent in your device, making it less effective. It can even deplete the battery directly by interacting with the chemicals that create electricity. Here are a few steps you can take to avoid moisture-caused battery drain:
- Open the battery door before storing the hearing aids
- Don’t keep your hearing aids in the bathroom, kitchen or other damp environments
- Get a dehumidifier for your hearing aids
- if your storing them for a number of days or more, take the batteries out
Advanced Hearing Aid Functions Can Drain Batteries
Current digital hearing aids help people hear a lot better than ones that you could get just ten years ago. But if you’re not keeping your eye on them, these advanced functions can cause faster battery drain. Don’t stop using your favorite features. But be aware that if you stream music for hours from your mobile device to your hearing aids, you’ll need to replace the battery sooner. Noise-canceling, Bluetooth, multichannel, tinnitus relief — all of these extra features can drain your battery.
Altitude Changes Can Affect Batteries Too
Your batteries can be sapped out if you go from low to high altitudes particularly if they are already low on juice. When skiing, flying or climbing always brings some spare batteries.
Perhaps The Batteries Aren’t Really Low
Some models will give you a warning when the battery begins to get too low. As a general rule, these warnings are giving you a “heads up”. It doesn’t mean you have a depleted battery. Also, the charge can sometimes drop briefly due to altitude or environmental changes and that can activate a false low battery warning. In order to end the alarm, remove the batteries, and then put them back in. You may be able to get a few more hours or even days out of that battery.
Handling Batteries Improperly
You should never take out the little tab from the battery until you’re ready to use it. Avoid getting skin oil and dirt on your hearing aid by washing your hands before handling them. Don’t ever freeze hearing aid batteries. It doesn’t extend their life as it might with other kinds of batteries. Hearing aid batteries might lose battery power faster if you make these simple handling mistakes.
It’s Not a Good Plan to Purchase a Year’s Supply of Batteries
Buying in bulk is often a smart money decision if you can afford to do it. But the last few batteries in the pack probably won’t have full power. Try to stick with a 6-month supply or less unless you’re fine with the waste.
Buying Hearing Aid Batteries on The Internet
It’s not a general criticism of purchasing stuff on the internet. You can get some great deals. But some batteries that can be found on the internet are being sold by less honest individuals and are near their expiration date. Or even worse, it has already passed. So buyer beware.
Both alkaline (AA, AAA, etc.) and zinc hearing aid batteries have a date they will expire. If you were going to buy milk, you would check the expiration date. You need to use the same amount of caution with batteries. Make sure that the date is not close to the expiration to get the most use out of the pack. 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. Be sure you know and trust the seller.
Current Hearing Aids Are Rechargeable
Hearing aids might drain too rapidly for a number of reasons. But you can get more life out of your batteries by taking some precautions. If you’re in the market for 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 need to be changed every few years.
