I recently bought a new P520 camera. I have only used it a couple times. After unpacking it and going over the manual, I inserted a SD card and charged the battery. I took a few photos around home which seemed to be okay, and turned it off. A couple weeks later I turned it on to prep for a hike, and noticed the battery strength seemed low, so I gave it a full charge while turned off. The very next day I took it on a hike and only got about 30 pic's in before it said: battery depleted. After getting home I again gave it a full charge while off, then turned it on, took one shot with the flash, and it immediately said battery depleted. Seems like a faulty battery to me, and hopefully nothing else is wrong. Any suggestions on where to get another Nikon battery for this model? Any other thoughts on what might be wrong?Harold
