I have been using the same atty and the same 3 batteries that I use and charge throughout the day, since November 09! I vape 2-3 ml a day and thought something would have died by now. The batteries are getting to the point of not holding their charge near as long but still going! I have never even cleaned my atty... I only use one type of juice so no flavor changes. I'm impressed! 
did I jinx myself??
