I traded yiutube chats with the Uber driver that was 115K miles on his 2019 Plus. He recently bought LeafSpy and it's showing 89% SoH. He has something like ~800 DC and ~800 full L2 Charges on the car.
With the hidden capacity at the bottom of the battery, that means it should be able to hold out the EPA estimated range for a long time. I have LeafSpy doing just about daily logs on my 2020 to watch the SOH tick down by hundredths of a percent every day, is interesting to see, but glad to know it's still holding +97% SOH after a year of daily driving and way over the normal driving distance that most people do monthly. :mrgreen:
97% after a year is unusual. I was in the high 92's or so after a year.

97 after 3 adjustment with a lot of driving is very unusual.

My S+ still hasn't kicked out of free Sirius mode, which made me wonder. Does something about the dealer prep for sale of the car start the bms adjustment clock? I ask because after a year in the lot, my SoH was still at 98.5%. (And first adjustment actually added .09%) that would correlate well to just micro ticks off the SoH and not a full adjustment.

I do daily QC, do you think that might be skewing the numbers? Latest reading at the bottom, screenshot from LeafSpy. I don't baby the vehicle either, charge to 100% semi-daily, QC like crazy, just like I did in my 2013 :lol:

nice. how many miles?

as far as skewing the numbers? Don't think charging method matters. It does appear that a greater driving demand helps keep SOH higher.

+15k as of posting, the 600 mile weekend trip gave it a big Boost before I read the forum. :D

time for an updated battery degradation graph. I changed to a polynomial trendline, SOH 91.24% at 20K. More leveling out

You might want to remove the extra "1" from your sig in your 5/4/21 Ah reading, unless you really have 1160.95 Ah :D

So you have had 2 increases and one Zero adjustment in 2 years. Nice.

Does anyone yet have any insight as to why some batteries flatten at 91% others 93% (my cars included), and one report of a battery staying at 97% (battery lottery winner?)

Good question, though mine seems to have hit an "adjustment" finally, made a jump down to 96%, but I guess still good relativity speaking?
