I took the K1 out of my closet for the first time in a couple years, and decided to play with it a bit. I noticed that the battery compartment was poking out a bit from the console. I took the battery out, and noticed that it looked pretty puffy (bulged out of its case), while my DS's battery didn't do this. Can any other K1 owners confirm or deny that their battery came bulgy? If not, I'll be buying a new battery (I've heard too many cases of batteries expanding and exploding inside peoples' phones to be anything but cautious).
