What are the true dimensions for the small & large batteries for the Panasonic HDC-TM900 camcorder? Small: VW-VBN130 1250 mAh; Large: VW-VBN260 2500 mAh. Both advertised s being 5.9" in height (depth). The supplied battery is the VBN130 & it measures 1.5 x 1.5 x 1" depth &, installed, is flush with the rear of the camcorder. Panasonic Tech Support not real Helpful. At a forum, an owner took a picture of his camcorder with a VW-260E (not sure what the "E" means) and the battery was flush with the rear of the viewfinder with the viewfinder extended 1". I can't believe that the large battery (VBN260) is double the capacity of the VBN130 but is 6 TIMES longer (5.9") which would make it longer than the camcorder (5.75").
