The NiMH patent was filed on December 2, 1998. The grant of the patent is 20 years (and the clock starts ticking on the filing date, not when the patent was approved). So, it looks like it should be available December 2018!

And, as was mentioned a few posts ago, the European version of the Prius V uses Lithium. I had assumed it was in order to make room for the extra rear seats. But now I'm seeing that there may be more going on than just that.

Honda gets their NiMH batteries from Sanyo which is generally well regarded in the business. (Ford also gets their NiMH batteries from Sanyo).Herm said:Stay away from Honda nimh batteries, lots of issues there.
