When I bought my hearing aids through my audiologist, they threw in three years of free hearing aid batteries. This is awesome. Batteries cost so much, and naturally my "stock" of 675 batteries had turned useless since my new aids take 312s. The doc started me out with Energizer batteries, which lasted a couple days at most, then started giving me Rayovac Proline batteries. I loved those; they lasted me a week or so at a time.
My audiologist recently switched brands so now I'm getting "Audigy Group" batteries. Audigy Group is a member owned audiologist organization. Now, these batteries are distributed by Audigy Group but I can't tell who manufactures them. There is no logo on the packaging. It may be Energizer, because I've found a few websites that list Energizer as being linked to Audigy Group, but if it is, they're not making it obvious.
Now for my take on these Audigy Group batteries. I haven't noticed any decrease in battery life. I am getting between 5-7 days of life out of them, and that's fine, about what the Rayovac Prolines did. No complaints there.
Unfortunately, I do have a complaint about the packaging. If you are a hearing aid user I'm sure you're familiar with typical hearing aid battery packaging. The batteries are usually in a plastic case with a strip on each battery. Removing the strip activates the battery, and also provides an easy way to put the battery in the aid without getting your skin oils all over the battery.
This is the front of the Audigy Group battery packaging:
And the back. You can see it's got a "flower petal" design. You pull back the cardboard packaging to see black plastic.
You have to pull at the black plastic to see the battery:
You can see the battery is clinging to the black bit. You have to pry the battery from the black plastic in order to put it in your hearing aid. Your skin oils get all over the tiny battery, and besides, good luck actually getting it off in the first place. You need two hands. Well, actually three, one to hold the package, one to hold the black plastic down and one to remove the battery.
As you can imagine, putting a battery in my hearing aids is a chore now. And I'm 23 years old with healthy hands. I would hate for an older person, a person with vision difficulties, or someone suffering from arthritis to have to deal with this kind of thing.
The audiologist asked me for feedback on the new batteries. I might just print out this blog post to show him!
