Thanks

The reason is that I've read on MNL that the traction battery may not balance the cells if it is only charged using a 120v Level1 charger.
That said, a "typical" unbalanced battery has a random assortment of low and high cells, and your LeafSpy seems to show just one high cell, so I suspect that 120v L1 vs 240v L2 isn't the issue... just mentioning it as something cheap & easy to try.

L-1 charging will in fact balance the cells, at least under normal circumstances. The amperages involved are actually very small. It may possibly even work better, as the BMS will have to spend a bit longer balancing.

The leaf was taken to another Nissan dealer in Petaluma Ca where the customer mattered. fellow posters guided us on how to gather data using Leaf Spy Pro. It was presented to the Petaluma Ca Dealer shop and more importantly they listened. The shop called me within an hour to state they also felt there was a cell pairing failure as one group was overcharging. They were doing more testing to confirm the diagnostics. Shop called again about 5 hours later to confirm cell failure and report that Nissan agreed to honor the warranty, replace the cells and have the car ready Tuesday. We would have a $350.00 deductible all in!!
My Niece could not be more ecstatic!! She learned a tremendous amount about care of her Leaf, use the Leaf Spy Pro as a maintenance tool and of course how many kind and helpful people are out there who deserve our gratitude.
Thank you all so much.
You guys ROCK!!!
