If someone tried to replace a battery with a metal box or taped a knife to the battery itself, I would know instantly. The reason we ask that the laptops come out of the bag has nothing to do with the battery; it has to do with the fact that it's easier to clear both the laptop and the bag if they're run seperately because then you get a better image of each.
