From what I can see from the service manual, this is not a CR2032 coin cell battery. It's a rechargeable "figure 8" type battery with wires and connector. If you google "VGNNR260E CMOS battery" you can get an idea what I am referring to. If needed, the part number is 1-756-650-11 and can be order through Sony Parts @ 800-488-7669. It is located underneath the mainboard, on the opposite side of the memory slots.
