Hi! I'm new to the site. I have been cigarette free and vaping for over a year! It has been the best thing. But I have been having issues with my batteries. I have already thrown 2 away thinking they just wear out eventually although 2 batteries at $25 dollars in a year seems alittle odd. I have always used the smok brand battery. The 1st two always worked fine until one day they just didn't. They would be working fine then suddenly die, and when I'd put them on the charger, the light would light up, but not blink when I took it off like normal and not light up/turn on anymore after that. I have tried using other chargers. Does no good. So, I'm just looking for some feedback seeing if anyone else has came into this problem. My 3rd battery I've got started doing this last night and now I'm having to use a e-cig to go battery which does not hit has hard for some reason. Thanks for any help!
