I have yet to read about a hybrid owner or an EV owner having to replace their batteries.  I know it has to happen but it is an exceptional case.  The Prius has been out for over 18 years and many are used for taxis which log over 500,000km before they get rid of them.

If batteries are the weak link in EVs. and they probably are, then the EVs will be coming on very strong.  I see the Bolt and the Tesla X making it over the threshold of practicality and being held back soley by the limits of production.

Cheers,
