The lifespan of car batteries is 15 - 20 years, and they only cost a few thousand bucks to replace.

  The cost of replacing Prius batteries was a big concern ten years ago. Seems less of a concern today. As in no one talks about ti anymore. Probably because it takes a mechanic half an afternoon to do. And the cost of the batteries has come down. With the new generation of electric cars the cost of replacing the battery isn't what it would cost today, but what it will cost in 15 years. Probably will be reasonably cheap.

    > The cost of replacing Prius batteries was a big concern ten years ago. It was never really an issue in practice, because (iirc) they had a 10 year warranty but if they failed on year 11 or 12 then Toyota would still usually just replace them for free anyway. And for the last several years you've been able to just get individual cells replaced rather than the entire battery, so it's no longer expensive to begin with.

      I think Hyundai warrants hybrid batteries for the life of the car. California considers batteries to be part of the emissions control system. So has a longer warranty. Actual experience seems to show that hybrid and electric car batteries are lasting longer than expected. Except for the Leaf with it's crummy thermal management.
