battery technology Air Activation?
Posted: Sun Feb 28, 2021 12:30 am
I have recently adopted a new addition to my wardrobe--hearing aid behind each ear. Now I can hear the clicking of the turn signal in my car. And the radio is running at half the volume I used to use.
They are not 'rechargeable' Uses a tiny 312 battery which is about the size of a baby aspirin. All the brands I have looked at on Amazon come packaged on a little plastic/foil wheel, 6 or 8 on a wheel, in a blister pak. The battery sits in a little 'tray' within the electronic lump that sits behind the ear.
A single battery is reported to last perhaps a day, perhaps six days, depending on lots of different circumstances. When I walked around with them for the first time, my attention was mostly marveling at the change. I was given lots of data from the person making the final adjustments but I did not absorb very much of it.
She said something about 'air activation'. When changing batteries, the convenient way, for me is to open that tiny tray, shake or nudge the dead battery out and then reach for the new one. The individual battery has a sort of dumbbell shaped foil, sticking on one end to the battery. The other end makes a nice little handle to place the new battery in the tiny tray, then pull the foil off and close the tray. I think I have been doing it wrong. AIR ACTIVATION. Roaming around on the web looking for information on the best brand of battery, I find I should remove the foil from the battery and wait at least one minute, maybe a couple, before putting it in the hearing aid. This is described as air activation, something that gives the battery a much longer useful life. It will also require me to acquire a tweezer or small tongs to handle the battery with foil removed.
Anybody here explain just what is going one with this air activation?
