I decided to buy a Bloog. I had been using generic batteries from Lite Cig and Vapor 4 Life. I thought I would try a "name brand" one. It worked great, for about the first week or two. Now it wont charge at all or sometimes it will keep a charge for about 10 minutes. Everything is clean, nothing is wrong with my chargers. I went back to my trusty battery from Lite Cig and it still works like a charm.
