I would personally keep any tank full or at least partially gassed for storage. I do scuba diving and this is basic maintenance on scuba tanks. Never empty a tank to avoid moisture from getting into it, thus degrading the tank, the seals and the quality of the air you're breathing. I don't know that much about airsoft but I guess it applies as well.
