Power One Size 312 Hearing Aid Batteries (80 Batteries)

These are the same batteries that I has getting from my hearing aid provider but are less than half the price. Work fine and last about 5 days in my Widex Evoke aids.

Need hearing aid batteries ? THIS IS A GOOD PRODUCT, Reasonable and easy to install in the hearing aid device.

They last about a week in my hearing aids.So I know about when I will need to replace them.Thanks

Batteries are fine. Package is infuriating

Great price

Do not buy these. It is almost impossible to remove each battery from packaging. Each battery required multiple cuts through plastic and much prying to remove the battery. I was uncomfortable and felt unsafe doing that repeatedly. I finally found that a heavy metal tray with a lip on a solid surface or work bench made me feel safe enough to remove most of the batteries for use. I inadvertently cut several of the batteries making those unusable due to fir into my hearing aid. Amazon Basic brand is much easier to remove each battery and COSTCO brand is the easiest I have found. Unfortunately my nearest COSTCO is a 80 minute drive from my home on a good traffic day..

They are fine work well

easy to open. Will not buy them any where else.
