There is a specific range of serial numbers that are being recalled. I have a coworker that, between his office laptop and home, has 8 batteries for Dell model laptops that fall in the recall, but none of those batteries' serial numbers are on the recall list. It would not be uncommon for Sony to be using either different model batteries, or ones from completely different manufacturing runs/facilities. It's also possible that they had previously found and fixed the flaw, without knowing that the flaw could cause the kind of damage it does in customer use.
