I bought a manual KR808D-1 kit from Myvaporstore.com  I Love It!!!  It came with 2 batteries.  Everything is working great, just wondering how many spare batteries do you recommend?  I have been charging my batteries every night, so I know they will last me the next day. Didn't know if it may be a common problem to where the batteries just quit working.  
I just started vaping 4 days ago, and I started to try to quit smoking. Its working so far, but I don't ever want to be w/out batteries not working.
