RayovacSize 312 Hearing Aid Batteries, Size 312 Batteries, 24 Count

I purchased these batteries because they were not in child proof packages that require a pair of commercial size cutters.

Good deal.

It came very fast, almost a week earlier than stated. Product was as described. Would order again.

If you are hard-of-hearing, and use battery hearing aids, I can definitely recommend this particular make. I could hear better. Also no problem getting into them - no scissors required.

Can't speak to the quality of the product as my elderly sister just started using them. The batteries are extremely difficult to remove from the package. Not only child proof but close to adult proof. Can't say for sure but I suspect anyone with arthritus in their hands might require assistance. I ended up removing all 24 batteries from the packing and placing them in a plastic container. My sister's comment was not to purchase them again. Had nothing to do with the actual product.

The easiest batteries to open and not spend all day trying. 05246EZ

Perfect

The batteries I received were not in a sturdy plastic casing as shown in the description but rather in flimsy cardboard, causing them to fall out easily. When I tried using them in my hearing aids, they were dead within half an hour. I attempted another set, but they didn’t work at all—it felt like I was just wearing earplugs. A third set didn’t last either. In an emergency, I purchased Duracell batteries from CVS, and my hearing aids worked perfectly with long-lasting power. These batteries are unreliable, don't match the description, and seem as if they might have already been used or worn out.
