I love my Joye 510! I started vaping two weeks before Christmas and no longer smoke analogs. I am so happy. I am having a bit of a problem lately with batteries. I have had about 3 lately that work fine until you attach them to the atty. Then the light comes on for a second and it goes out. I don't know if I am doing something to them or if they have just reached the end of their life span. I hate to throw them away if there is something I can do. Any suggestions are appreciated.
