RCR2? Recommendations?

[Solscud007]

So my buddy Scout24 said that RCR2 are harder to find.



Is that the case for good RCR2? I found a RCR2 by Amstron.

It says RCR2 3v. anyone use these? I want to use it for my Quark Mini CR2.



Could I use my Ultrafire battery charger for this? Using a spacer of course.
