Interesting idea - if down the line you get your batteries replaced, something like this would motivate Nissan to give you a good refund on the batteries you are returning, or risk not getting them back. When the time comes to replace the batteries - I think dealers are now required by law to give you the replaced parts if you request them (a way for the consumer to be sure the dealer isn't just replacing perfectly good parts). Wonder is Nissan has thought this far down the road....bowthom wrote:That's the whole idea in my thoughts. When the Leaf battery ages to 80% capacity, replace it and use the old one as the storage for your house / leaf power. It could even be a DC fast charge. Not full bore like a 408V commercial unit but 20 ~ 30 amps so both packs live longer.
