Why does the L.E.D. stay lit for several seconds after I drag on the E-cig?
The battery uses a pressure switch to activate the battery. If the L.E.D. on your battery is staying on for more than a second or two after you stop dragging on it, your pressure switch may be getting slightly stuck. Try tapping the L.E.D. end of the battery on a hard, flat surface a few times (not too hard, just hard enough to give it a good nudge) and try using it again. This can sometimes unstick the pressure switch. If this does not work, try tapping the other end of the battery (the threaded end) on a hard, flat surface a few times and try using it again.
