Positives:
[+] No noticeable difference in capacity or charged level than name-brand
[+] Maybe even *more* capacity than name-brand!
[+] Perfect match in size (CR2)

Summary: I used this for a daily-use medical device which requires CR2 batteries. I previously used name-brand (Duracell/Energizer), but those were quite expensive. I decided to try these (a risk, as I was purchasing qty of 10!) What I found was that these lasted as long (maybe even longer?) than the name-brand. I normally replace the name-brand every 2 months. I replaced the latest one one in 3 months, even with daily (10 hours) of usage, and no known environmental changes. I haven't gone through all 10 in this pack yet, but hoping I'll get just as much life from the rest.

These did NOT work in a Bushnell golf rangefinder, apparently because
they are enough over-voltage (measured 3.24v) that the Bushnell's
protective circuitry kicked in. Varta cells measure at about 3.14v
and work fine in the unit.

I use these in a couple of systems I have that require this size of battery. For the most part these batteries have been fine and they are reasonably priced. I have had a few batteries that were defective in the Tenergy CR2 and CR123 batteries I have purchased, but the fallout rate for bad batteries has not outweighed the price advantage.

I bought these as replacement batteries for sensors. Several of these batteries either didn't last very long or were already dead when I put them in. Not worth it for the maybe 2 or 3 decent batteries in the whole pack. Will not be buying these again.

My local hardware store / drug store wanted 10 bucks a pop for cr2 batteries -no way ! I found these and I was skeptical ,expecting them not to work given the price . But so far so good . I used them for a bunch of my personal cameras and had enough left over to replace a bunch of student camera in my classroom ... I'm a happy camper . I put them in my instax share printer also so -i'll see how long they last in there....

These were almost dead when I started using them. I had a set of brand name battery that allowed me to shoot 7 rolls of film before they started to slow down This one starting to have issues with only 1/3 of the roll being shoot. I realize these are not name brand but I should have been able to shoot one roll of film with out issues.

It's refreshing to order a product and get what you paid for. My mother uses this brother for this acupuncture device we use for my brother's rehab and she loves this battery. She told me it lasts forever and is exceeding our expectation. Next time we need this battery again, i'll be ordering this same product from the same vendor, thank you!

I can only give it four out of fives stars as I do NOT know how long the batteries life is as of yet. Price great, The same battery at Radio Shack was $15.67 for ONE. I use these for my alarm system for my home. EAach wondow, door, etc. you know the magnetic type swithces.
