Here's a question for you "lifer" Leafers: if we had these kinds of numbers in 2011/2012, would there have been a class action law suit (for battery pack replacement)? Whether you look at it as a % loss or gross GIDs, I think the simple fact that we're talking about ~200 miles of range would have alleviated some of the range anxiety. I definitely think there's been an improvement in cell chemistry, but I still wonder what would have happened if Nissan just "bit the bullet" and pushed for a higher capacity battery pack initially...even if it added $10k to the cost of the car. The fact is, I really like my 2011 Leaf...now that it has a 40kWh battery pack.
Well, I predicted I would go below 90% by 2021 Q4 (just over 2 years) and still waiting. I am still getting negative adjustments but they have been pretty mild. .17% and .09% were the last two.goldbrick wrote: ↑Sun Sep 04, 2022 8:59 pm I see. I don't think I've ever had my Leaf under 7-9% SOC and normally I charge when I drop below 20% so that probably makes it pretty easy for me.
My Leaf is a purely in-town car and while I've done over 100 miles on a single charge (while staying within my self-imposed SOC limits) that is pretty uncommon. Most of my trips are 30 miles or less and for that, it is still just perfect. Hopefully the drop in SOH will slow down now that it's approaching 90%. At least that seems pretty common from what I've read here.
Pretty good considering the crazy weather you get. Your drop is anything but consistent. Unlike mine which was fast the first year dropping to "medium" for a half year to slow since then (about 1 =1½ % annually) you had a 5 measurement stretch with really slow drops in kwh replaced from 5/21 to 2/22 (61.96 - 61.21) but a much greater drop in SOH (93.20 - 89.95)GerryAZ wrote: ↑Tue Sep 27, 2022 8:15 pm Here is my latest full discharge test of the 2019 SL Plus. Three years of data indicate that the battery capacity is dropping slowly over time, as expected.

As you can see from the data, capacity loss has been fairly linear over time and about 4% per year (from 3.85% to 4.1% depending upon whether you consider LEAF Spy data or actual charging energy from the wall). I think this is reasonable for an average of 17,235 miles per year in the hot desert climate.
Hx is a mystery to me as well although I am seeing a bit of a trend with people who DC more than average maintaining a higher (105+) Hx but we get to gig drivers who DC a lot and it tails off so...maybe a sweet spot? But w/o knowing what Hx is, its hard to say if high or lower is better. Maybe 100 is the sweet spot and I am no better off at 115 than someone at 85? Seems far fetched but there are a lot of packs doing well with Hx in the upper 80's low 90's sooo...DougWantsALeaf wrote: ↑Wed Sep 28, 2022 7:49 pm Fascinating.
Here is a link to my 2 Pluses of about the same age, but fewer miles (SV+ built 5/19, and S+ built 9/19) A bit higher SoH. The drive to work now 2x weekly plus the trips to Kansas are starting to up the miles monthly now. The Hx I find interesting as yours continues to drop off. It does seem like longer drives seem to help maintain Hx.
