Hmmm. No, I haven't seen it myself but I was told there was
such a thing by a hardware oriented friend who doesn't do
software, but is a wizard on hardware issues. Besides, there
has to be some intelligence in the battery: Windows give you
a counter for the battery, and you can take the battery to some
other computer and get the same count, so there is something
in the battery that can be queried...
