Grrrrrrrrr... man, this is a drag, I was really hoping it was just going to be a simple battery replacement. I had doubts at first, but it seemed that it was looking like that would work. It is possible you got a second defective battery... but really, I doubt it. Just for grins bring this one back to the shop and have them test it. If it doesn't work out are you willing to flash a new rom or to just restore it?
