Sorry - guess I should have been more precise. Yes, I measured 4.20 amps in my UF-980L on high with one of the new Xtar 18700 batteries. I have a lot of strongly held beliefs about life, the universe and just about everything else. I write a lot about those kind of things so, that may explain why I'm . . . different. (weird)
Anyway, I am very pleased (so far) with these Xtar batteries - good quality at a great price.
Well, if you want to be happy . . . I'm just sayin'. There are many ways to reach that often elusive goal. If my way doesn't work for ya . . . there are others.
