A few more significant quotes from the article I linked yesterday:
And he confirmed that the next Leaf would continue with an air-cooled battery pack, saying changes in cell chemistry had "significantly reduced" concerns over battery durability.
"I am not concerned any more" about the durability of electric-car batteries, he concluded...
Well, those of us who have a capacity loss of 30% in 5.5 years on our Nissan Leaf are
concerned. I will wait to see what the battery capacity warranty is on Leaf 2. Any such statement is meaningless without a warranty to back it up.
Lifetime 5.5 m/kWh (Dash) over 57,200 miles / 67 months
Capacity Loss Predicted - 27.4% Actual - 30.1%

I doubt Nissan is very concerned about losing future sale to those few 2011 to (early) 2013 LEAF owners who still confuse inaccurate LBC-indicated battery capacity loss (gid
and capacity bar loss) with actual
battery capacity loss.
Nissan knows that the change(s) it made in the gid
and capacity bar display of new LEAFs in 2013 will mean it will have far fewer complaints of capacity lossfrom the those who rely on gids
/bars and never monitor their actual capacity loss, whether actual
LEAF battery durability has been improved significantly since 2011, or not.
After I had my 3G TCU upgrade done, I had a long discussion with my local Nissan service adviser RE my own pack, which at almost 50 k miles and nearly 6 years from manufacture now shows LBC calculated capacity loss of ~31%, and is approaching 20% actual capacity loss, as estimated by the charge accepted, as reported by my utility meter.
From his comments, and the reports of others on this forum, it appears Nissan has adopted a policy of providing something like a de-facto prorated pack warranty for some
early LEAF owners, which, IMO, while not defective in terms of capacity loss, were probably defective from the standpoint of initial capacity on delivery.
At this point, my advice to all LEAF owners interested in trying to get assistance from Nissan in replacing their packs after warranty expiration, would be to make no efforts to intentionally damage your pack, and maintain a cooperative relationship with your servicing Nissan dealer.
Nissan might well prefer that problem
customers who will not do this would buy their future BEVs from their competitors.
If and when I decide to replace my own pack, I will report on how this situation is resolved.
