I believe he has just 2 cells in that wrap of his. He ids them as 4800mAh thus giving the 9600 ttl. If you are correct and ca. 1500 is a more realistic capacity, that is about the same as a dual scud/polarcell setup.
This is the same game as with the replacement "stock" batteries. As dr_frost_dk has shown in many cases it is "liar , liar your capacities on fire...."
