I'm a little confused about batteries. 
I've seen CR123, CR123a and 16340 used interchangeably and/or together in many places. Are these just different designations for the same battery, or are there slight differences?
The reason I ask is that I'm looking at buying a mod that uses:
CR123 (16340) 3.0V
My husband has a huge flashlight collection, most of which use CR123's. I'm trying to make sure everything is compatible so I don't blow up a flashlight, or worse my mod.
Thanks!
