PanasonicCR2-2PK Photo Lithium 3V Batteries for Mini 25, Mini 50, Mini 50S, Mini 55, Pivi MP-100 and SP-1- Silver (Pack of 2)

Installed in both rangefinders. Both improved. One battery was inoperable.

Odd size but fit correctly and worked great.Would buy again.

I was VERY happy that I was actually able to get this sent via mail to my mail box here in Alaska. For some stupid reason there is a restriction on sending (some?) lithium batteries via mail to us, DESPITE the fact there is no restriction on MUCH larger lithium batteries in the mail to the same address (which is stupid IMHO. There should be no shipping restriction at all.). But I was able to ship these to my house, and to put into my fire alarms, so they quit beeping at me, PLUS I didn't have to put myself at risk by walking into a store and exposing myself to Covid-19 during a pandemic. WIN!I just put these in a month or two ago, and haven't had an issue with them yet.I knocked off a star, as they didn't fit in my Atom smoke alarm too well. The design of the positive prong (+) on the end is sort of short, and rather wide, and it didn't work easily with my fire alarm. I had to peel back a bit of the wrapper on one battery, in one fire alarm and work it around a bit to engage. The other one worked OK right out of the gate, but it would be good of them to redesign the positive prong (+) so it is a little narrower, AND so it sticks out a bit more, like other batteries. Still, it would be fair to point out that the battery space of the fire alarm could be improved as well (it is rather tight).Regardless, I am happy I got this purchase, and despite a few minor issues, they met my needs so far.

Good value

I love Amazon

I'm not sure what to say, but if you're looking for these specific batteries, then these are real batteries.

They are fine and seem to be lasting

Quick delivery and as advertised
