I change out the 18650 after 24 hours just as matter of course.
Have done that with everything apart from an Altoids Box that runs 2 x 18650's which I have never been able to kill off completely.
I do that as I know the battery could die in the next 12 - 18 hours I am at work so just swap it out as I have a few 18650's so it is easier to swap it than to be possibly vapeless. Sort of paranoid about the vapeless thing having had it happen to me once I take the VMod and a ProVari into work, sometimes the Altoids Box depending on what is in the tanks.
