CR2 3V Lithium Battery 1000mAh, 3 Volt Range Finder Battery, Long Lasting Power, 6 Pack High Performance CR2 with 10 Years Shelf Life for Rangefinder, Flashlight, Alarm Systems, Mini55

Great for range finders that get a lot of useCommercial brand names don't have this capacity. Would buy again

I initial review. I just bought and charged them with an olight usb charger so I could use one in my crimson tide laser/flashlight since the stock lithium battery was below 3 volts which means it's "dead".These recharable cells would peak at 4.24 volts with an olight USB charger. I'm not sure if the charger or the battery decided that was at peak voltage, but all 6 did the same.These arrived mostly charged reading at 3.24 volts. The point 24 volts us what the device you use will power from, after the cell reaches table voltage which is advertised voltage, then the cell is technically "dead".I just put a top charge to them.I have not run them thru my mahaa battery charger/analyzer that also shows how many miliamps the cells hold yet. For the price and convenience I'm not all that worried about it unless they deplete too fast and then I'll test them and make a warranty claim if they are unsatisfactory.I'll add some pics for you. They come in a small cardboard box that I'll upgrade to plastic.So far I can recommended them. My laser/flashlight combo is much brighter now and I won't be stuck tossing expensive batteries away.

One of 12 failed within 45 days in a window sensor. Hopefully it was just a random defect. These replaced 11 Everready batteries in my security system that faithfully lasted 8+ years before the first low voltage warning. Hopefully the 10 others installed hold up a few years. You take a chance with off brand batteries but the low cost makes them very attractive.

These were the best price and so far they are great

Great product
