Charging the batties won't affect the shelve life. I really like the tea bags so I don't have to buy cartridges. By the way Hangtime, I used to smoke weed and went through 30 years of marijuana prohibition which sucked. I been reading this forum and if theirs a ban on e-cigs I don't want to deal with any stress , so i'd rather have a 2 year supply and live peacefully mellow.
