It looks like the AH batteries are manufactured by A123Systems. The cells BMW uses are cylindrical cells, MADE IN CHINA.
And A123Systems filed for Ch11 bankruptcy. Lovely. Looks like Johnson Controls will take over. Hopefully that's for the better.
Yes, I'm sure the lifetime warranty makes mention of decay. I'm trying to get the exact verbiage. I saw that about A123, it's been getting a good bit of press.
Some of the things that would prevent an AH3 from being a "common sense" choice would be:
A) You plan on keeping the car 10+ years
B) Your negotiated price delta over a 335i is >$2K USD. With current promotions, it's only a $3K increase (officially). Seems like virtually all dealers would be more eager to give you an aggressive price on the AH3 vs a 335i/330d/335d, due to popularity of the petrol/diesel models vs. a "new" tech hybrid.
