So I'm still enjoying my blu, but when a friend of a friend found out I switched to PVs and so far prefer cigalikes, he offered to sell me his old V2 kit. The thing is, it's about two years old. He said he only used it about 5 times, so I'm left to assume that the batteries have been sitting for over a year without having been used and/or charged. So assuming they were dead or nearly dead when he stopped using them, is long term storage for LiPoly batteries safe if they're not charged? OR if they were fully charged, wouldn't they have drained themselves dry by now anyway? He's got a couple nice extras like a USB power-cig that I could use at my desk all the time, so I'd like to buy the stuff if I can get a good deal, but without knowing if the bats are even any good, I don't know what to offer him.
