I purchased the P1 very early in 2001. I first noticed the problems after about 6 months and then my other spare battery soon after experienced the same. Love the camera, hate the batteries!I'm a Sony lover...32" XBR2-100-$2500, Camcorder, Beta, VHS, CD, boombox, on and on.....this is very frustrating to mess around with the batteries. Hint, buy new and send the old battery back to Sony for warranty (you now have two newer)...If they catch me, they can take me to court...I'll give the camera to the judge and see what it's like to be stuck with a displayed fully-charged battery that works for 2 pictures!
