Ok, so have my EGO 650ma and the batt lasts pretty much all day between charges but I would really like to try LR atty/carto for more vapor. How much more battery do the LRs use? Anyone have a direct comparison of standard vs LR attys and battery life (use time per charge)? Will I suddenly find myself with a dead battery half way through the day if I switch to LR attys/cartos?
