'Just noticed there hasn't been any activity here for a while. Years, actually. are these things still being manyfactured? In any event, here's a contrib. I used to use a 901 (remember those?) XL as they had the highest MAH and voltage output of any of the cigalike configuarations. actually, I had a pair of them, both in chrome. I'd hook up a ni XL cartomizer and a nickle-colored LR XL cartomzer to which I'd attach a SS drip tip. it lookled pretty flash and performed as well as could ever be expected from any battery that size. Lessee, that woulda been, what, four years ago? Thereabouts. In any event, there are better alternatives than a disposable for those still fighting the tobacco urge, particularly now that we have palm-sized VV/VW boxes. Personally, as much as I love every aspect of vaping, I'd quit before ever touching another cigarette.
