What is the estimated life span of the batteries in the Leaf? And the replacement costs?
Those are the big questions. Nissan has informally stated that the average driver will see 80% capacity left after 5 years of driving. However, there are some drivers in Phoenix already down under 80%!
Nissan explicitly doesn't warranty battery capacity, only "sudden failure".
This is why I said that drivers in hot climates should plan on 2 or 3-year leases. I live in a pretty temperate climate and after 1 year & 15K miles, I'm seeing very little capacity loss.
As for replacement cost, I've heard that Nissan will replace a battery pack in a car for $5K. The certainly won't sell it for that to a random person for some other purpose. However, no one seems to be able to get a price out of Nissan.
Part of this may be that Nissan is just starting battery production here in the US (TN) and this may drop the price significantly.
