The only CR123A's I buy
Since the earliest of the CR 123A cells coming out, and the prices at the time of $10 for two at the time anywhere else, all I have used for years is the Surefire batteries. So, for years in law enforcement and government contract security, I have depended on them. I said for a long time that the LED was the future of tactical lights, and now that it is, the LED lights and the Surefire CR 123A's are always with me. Avoid any import versions, especially, as they have caused the lights to catch fire! These cells have a LOT more juice than you might think! I even tape over the used ones I toss out, to avoid any accidental fires! And Surefire led the way for long term storage batteries! Ten years is great!
