New?? Its 5% degraded. I would be a "bit" upset if anyone passed this off as new.

Most of my trips have only been down to about 50% battery, not sure if I've been on a really long range drive with it yet, I'll give that a try today and see if anything changes on the LeafSpy screen. I picked up the car used from a Nissan Dealer, but they don't know the history of the car either. So no idea if the battery was replaced at all during its previous life.
HIGHLY unlikely it was replaced. This is the norm in your location for 2015's. Some of your numbers are off. the 100%+ SOH is obviously incorrect. I would look more to ahr and Hx for a more realistic picture.

No. that reading is typical for a 2015 chemistry battery. The AHr capacity is higher than the 2011-2013 batteries.
This is the reading off the new battery installed in my 2013 SV last October.
Oct 20, 2017 - AHr=65.40, SOH=100%, Hx=100.00%, odo=25,771 miles, QC=4 L1/L2=2262
This is what it read today.
Apr 20, 2018 - AHr=64.88, SOH=99.2%, Hx=96.78%, odo=27,247 miles, QC=4 L1/L2=2553

Thanks for the input everyone.

Here's some more screenshots with a few hundred more KM's added on. Seems like we've got a good battery so far!

Indeed.
The Gids value in particular is spectacular.

I'm wondering if this isn't a very active forum, or maybe I've posted in the wrong area?
I also have seen this result: Nobody seems to have an explanation, we are told the 430R resistor in the BMS is the bleed resistor, with 10mA bleed!, but that does not work for me, far too low? And the Leaf does a fantastic job of equallizing the pack. There are also too many passive components around the BMA, and indictors in series with every balance connection, seems to me it could be active balancing, has anyone EVER measured the balance current capability? shunt 1 cell pair with a 10R 5W resistor and measure the current in the balance wire. Also check the voltage on the bottom balance wire with a scope, see if there is an ac component.
If it is active, then the red bars may not indicate a shunted cell, may be the cells that are receiving charge from others.

GIDs is a derived value and is "adjustable" which tells me a review of the watt hour value is in order.
