Is it normal for the psp's battery to well...to inflate? Not in a balloon kind of way, but more of a getting bigger kind of way. I've notice that my psp battery cover is poping out. Im pretty sure nothing is in the place the battery is but everytime I take off the cap it gets really hard just to put it back on. Now my battery has a crack on it(pressure from cover pushing down on it). So does it get bigger for some reason?
