Power One Size 312 Zinc Air Hearing Aid Batteries No Mercury (42 batteries)

got them in one day and reasonably priced

This is a replacement purchase. I love the quality and long lasting performance of these batteries. I have tried other brands but keep coming back to these. They were also recommended by my hearing aid provider and I can see why. For the performance and price you can stock up and never be out of batteries when you need them.

Seems like the batteries age and loose power as you get the the last one in the package

These batteries are great! They last exactly one week in the hearing aid of my mother. Very reliable, highly recommended.

I purchased these for two hearing aids and began to notice if the hearing aids didn't work well changing the batteries would fix the problem. I didn't notice this problem with the generic Amazon Label batteries. The price was good but now I'm trying to use them up so I can go back to the Amazon Label batteries. I wouldn't notice the other batteries were low until the hearing aid told me to change the battery. That doesn't happen with these as I keep changing the batteries early. Maybe it is just a bad batch or old batteries.

I only buy this brand of batteries because they last longer than all the other brands

VERY HARD TO REMOVE BATTERY FROM CARDS AND THEY DO NOT LESS LONG !!!

Good hearing aid batteries.
