Any cell that says "made in china" on it's side *could* be a problem... not so much in that it might not work, but that if it explodes and destroys that pricey flashlight, or anything around it, you don't have anywhere to turn. Most USA based cell makers will replace anything one of their cells destroys.
Considering the cost of an A2, I wouldn't bother feeding it junk. use quality USA made CR123s, (panasonic, duracell, surefire, streamlight, batterystation, rayovac, etc).
