All the details are in this post, but basically, Nissan, starting in May, is selling LEAF "refabricated" replacement batteries. In Japan. A 24 kWh battery will be around $2,850; a 30 kWh box will go for $7,608, and a 40 kWh is a comparative bargain at $7,798. Nissan doesn't say when, or even if, the program will begin outside of Japan, but I have to imagine that it will. Eventually.
