Wow! I'm so glad that I read for weeks and watched the Noob video's etc. I just received my first ecig. I got the DSE901 and into my first day vaping. So far so good....just one question. The batteries info from my vendor said that the batteries where completely charged, not so, but that's ok because the shipping was super fast. So I've read that you should charge 1st time for eight hrs. How long after that for each charge does it take?
