Hi there. I want to ask you everything you know about the differences between fake and real 2200 mAh batteries (stamina pack). This is because I want to buy one in Mercado Libre (mexican ebay), from some guy that assures they are legit. I've had a copy that looked legit once, so I want to make sure. This person sells them in their blister, but I don't know if it's a well sealed one.
