From what I know about Li-ion batteries, being in the electronics trade since they came out, I think that is extremely optimistic, and think that probably refers to ones that have been replaced in newish cars. After a number of years those type of batteries gradually loose their ability to hold a charge which may not be noticed on short runs but would show up on long ones.
However I hear they are working on some new design of batteries now, different chemical make up, that when available
will be more effective and charge very quickly, but they are a few years away yet.
