i too have fitted the ipod battery from the generation 1 ipod. my H320 runs fine with no probs. only had to swap the red and black wires carefully with a pin in the plug. trim the excess aluminium at the sides of the battery(not essential tho. just makes closing easier). I removed the 4 black foam pads from inside the back cover as well. no need to remove the blue insulators. Just ensure u dont pinch them when clipping the back cover on. got the battery for £10 on ebay
