Damnit, the Lipo battery industry needs better standards!

I've been storing a few of lipo packs I don't use anymore fully charged for a few years now just to see if this claim is correct. Well, none has puffed and I even charged a couple and ran them. Well, they still performed the same way they did before I stored them. A couple of the packs doesn't have balancing wires on them and no problem at all. I hardly balance any of my packs and none have shown any sign of puffing. Now one pack that I don't use anymore is composed of many cells and that packs has been stored fully charged for almost 3yrs now. I only check the voltage to see how far it has drained and it is at 12.3v, not bad when fully charged is was 12.6v.
