I just did a Leaf Spy reading after (roughly) 6 months of ownership on my 2019 SV. The results are not encouraging. It would seem I've already lost 5% capacity.
Purchase date: 4/30/19. Build date: 02/2019.
Leaf Spy Reading: 11/23/19
SOC: 79.7% (dash says 81%)
Remain: 30.0 kWh
My daily charge is to 60%. My wife and I do use the Leaf as much as possible - we use it for about 85% of our driving (17,000 miles a year projected) and only use our Honda CRV for about 15% of our driving (3,000 miles a year projected). And I did take the Leaf on several medium range road trips this summer and fall - NYC to Boston and back 4 times, NYC to D.C. and back once - during which I obviously QC'd, but I never drove more than 200 miles in one day and never QC'd more than twice in one day. So I'm hoping that this apparent 5% capacity loss in 6-7 months time can be explained by Leaf Spy's supposed 3% margin of error. Otherwise, unless there's a serious drop off in the degradation rate, I'm on track for 10% capacity loss in the first year.
I do, however, still love this car.
