Yes, I think that's great. Didn't they complain in the same breath that the Japanese were stealing all the critical parts for hybrids?
I believe the makers of appropriate batteries are all in Japan.  It would be kind of funny if someone did complain about them using "our" batteries.  Reminiscent of other people owning "our" oil.

FWIW, Ford may have some frustration about that situation ... but energy might be better spent finding/creating US suppliers.

american car makers are so far behind the japanese that ford licensed hybrid tech from toyota
