Nissan Leaf and battery life

A recent review I read while researching for Nissan Leaf and how often would I need to replace the batteries. Its a totally new concept for the mass production and as the sample size is much bigger now there's a chance of more things going wrong.

 All in all, I would expect the Leaf to have comparable, if not lower, total cost of ownership when you factor all these lifetime costs in. You'll be buying a new battery when most folks will be buying a new car (and maybe some seat covers). Of course, since batteries are getting twice as good every five years for the last two decades, you may replace the battery with a cheaper one for the same range or get more range for the same price. There is a good chance that we may trade in batteries sooner if a secondary market for old batteries for UPS or power shifting develops.
