Just got my 510 today. Thanks all for the advice, this thing rocks. However when I put the battery on the charger, it fits really loose and I have to wiggle it around before the red light comes on. Is this normal for these? Also, the charger has a 12" cord which isn't very handy cause I can't just let it hang, I have to set it on top of some books or something because it's so touchy. I just need to know if this is common (the touchy part) before I ask for a replacement.
