Hey everyone I just wanted to get some opinions on this subject. I have a JS and am looking for those elusive ICR10440 batteries from a vendor here in the states. But I wanted to see from others experiences do they last longer (both in run time and in life span) than the standard DSE801 batteries? I know the mAh rating on the standard ones is lower, but I have never used one so I do not know. For some background on this, I got my JS 5 months ago and in the time both the ICR10440 batteries have pretty much died. By that I mean on a full charge I get about 4 puffs before the performance drops significantly and I have to recharge or it feels like I am just breathing flavored air. I love my JS, but the now lack of portability away from some form of power source is getting a little old.
