It's most likely a knock-off where it was from eBay (most there are.) I know if I go into my power settings in XP by double clicking my power guage (the Lenovo one, I'm sure they've got something similar in Vista) there's a Battery information tab. It displays the month and year the battery was first used and the cycle count. If those are way off, then you may have an old battery.
