Newest Rayovac Proline Advanced Size 312, Active Core. 48 Batteries, Made in USA

The batteries are fine. The child-proof packaging is a nightmare.

been using these for over a month now. Batteries seem to last a few days longer then the ones I was using.

The sealed package is a nightmare to open! There is no EZ access pull tab to get the batteries out. A scissors won’t cut the heavy plastic, and you can’t pry it apart either! I actually had to use a tin snips to cut the package open! Good luck if you buy these!

These last a couple of days longer than the older batteries for my hearing aids. I do not like the packaging....the batteries are difficult to get out. No complaints with the batteries though

I have gotten batteries from them the last 2 years. The batteries definitely last a day or two long than less expensive ones. A quality product which is the only one I buy. This one is most recommended by audiologists

Bought these since I was in a pinch and couldn’t get to Costco. Child proof packaging is the norm now, so I expected it, but this is worse than others, like Kirkland. I had to cut the entire card apart and transfer to a holder I had from some old Duracell batteries. There is no way I could have gotten a battery out if I was somewhere without scissors. Given that most hearing devices are used by older people, why not have child proof and regular, like pill bottles. No children in my life. The batteries don’t seem any better than the Kirkland, and possibly last a little shorter, yet more expensive.

So far so good. Last batch of Rayovac batteries I ordered were short lived. I realized after using a few the sticky gum from the tab was remaining on the battery causing the short life. Again, these do not have that problem and so far I am pleased with the battery life.

Perfect.
