I agree, run time should be depends on the mAH, more correct way is multiply the voltage to get Wattage.
let say
RCR123 3.7V x 750mAH = 2.775W
14
500 3.7V x 750mAH = 2.775W Should be same, unless
1.2V x 2000mAH = 2.4 W
so a AA NiMH would have less juice than the RCR123 at 750mAH.
But according to the runtime graph, 1 thing we need to consider is the output, Quark123 and AA has same brightness?? I checked 4sevens side, the Quark123 and AA has different brightness and current draw. So if one is using RCR123 3.7V x 750mAHÂ and the other using 14400 3.7V x 750mAH , the AA using 14400 3.7V x 750mAHÂ will have longer runtime due to less lumens or current draw (brightness), not the physical size though.
My humble opinion lar, don't bug me. I already got hard time to explain to my another half why my name is in the 9th Jan gathering liao..

Your concept is correct. The website showed measured the Quark AA with NiMH though (350ma on max).
The Quark 123 and AA has the same head, if run on Li-ION 16340 and 14500 it will eat 700mA at Max.. so the output should be the same. Buttttt.....
Selfbuilt's review, showed that the 123 and AA has slight difference output in the lightbox.


That little -3 difference gave 10mins+ more runtime

Or perhaps, damon was right.
Size does matter. 
Your other-half worried you going into the jungle? or take up family time

pseudo, could i suggest you to post "the welcome mat" at the 1st page?
Yeap, i'll get to it later.
There's a new Battery & Charger section @ Post #3.
