Hmm. We have two 2016 LEAF SV.
(Back story: LEAF #1 had 145 miles on it after being driven into Seattle for a car show and occasional test drives. Of course, I was concerned it was a dealer demo or customer return and thus not eligible for new car tax incentives, but verified via CarFax that it had indeed never been sold or titled. Given it had been manufactured 10/2015, having it driven is probably better than not.)
LEAF #1 (before driving home from the dealer
)
Date: 6/3 Odo mi: 154.1
Gids: 353 SOH: 98% Hx: 93.49 AHr: 78.646
L1/L2s: 6 QC: 5

LEAF #1 (two weeks later... :shock: )
Date: 6/15 Odo mi: 508.9
Gids: 337 SOH: 93% Hx: 89.92 AHr: 74.457
L1/L2s: 18 QC: 5

LEAF #1 (most recent full charge
)
Date: 8/31 Odo mi: 2374.3
Gids: 348 SOH: 95% Hx: 90.86 AHr: 75.8
L1/L2s: 88 QCs: 10
Balance: 11 mV
What brought the stats back up was some mountain driving (4000' pass with two QCs and one 100% L2 that day, with a peak battery pack temp of 117F), plus occasional QCs in the subsequent week. Each QC seemed to bump the SOH up a percentage point, and there they have stayed since. I've also learned to store the car at 40-50% SOC if storing for a week or longer... it holds the stats better, vs. a leaving it at a higher SOC.
The other 2016 SV was built on 2/16. While I don't have LeafSpy number from the drive-off day, I do have a few "core samples" for comparison with mine. The stats are now fairly close between the two cars.
LEAF #2
Date 6/11 Odo mi: 401
Gids: 354 SOH: 97% Hx: 92.51% AHr: 77.37
L1/L2s: 15 QCs: 2

LEAF #2

LEAF #2

At some point, it really comes down to just enjoying the car. All Li-Ion packs degrade over time and cycles with various factors affecting the rate of decline, but it's not like it's going to leak oil or fail emission tests. I suspect the capacity warranty is a pretty good guess on how Nissan expects these batteries to perform: 96 months / 100k miles to no fewer than 9 capacity bars. Time will tell, and by that time, there will be some tempting alternatives.
