I think there has been some confusion here between
short batteries (i.e., GreenCig size) and regular/long size 280 mAh KR808D-1 batteries (distinguished from the newer extra long size 380 mAh KR808D-1 batteries).
Until recently, you'd have to buy the $139 "
GreenCig G-300 With Charging Case(Shorter Batteries)" from NHaler to get a cartomizer e-cig about the size of a 100s analog. Since the GreenCig cartomizer works with KR808D-1 batteries (automatic only), I
assume that a KR808D-1 cartomizer works with these batts.
In just the past few days, Vapor4Life has begun selling the "
Vapor King Short Battery" (in four color choices) for $13.50. They
appear to be about the same length as those GreenCig batts (and may be GreenCig batts, but that is pure
speculation on my part).
Notice all those assumptions and speculations. Confirm with supplier before ordering.
