LeafSpy) is 96.69% at just over 10,000 miles.
That's for the 2019 plus, correct?
Yes, the 2019 Plus. I had my third big battery health drop after posting that, though, so now I’m at 169.19 aHr and 95.91%.
What's going on there?
I am strongly considering getting a 62kwh battery for my old leaf and trying to figure out what I'm getting into.
I can easily get a 40kwh, they're everywhere, but I think I want to hold out for the bigger one.

The regular 3 month drops appear to be the BMS recalibrating, while the gradual day-to-day degradation appears to simply based on a formula that uses mileage (and maybe time?). The 40kWh pack behaves exactly the same way, and at least Dave here has seen the 3 month adjustment bring his battery health back up slightly. My best guess is that I'll reach 75% at 100,000 miles and just under 8 years.

Does colder weather tend to reduce SOH, or is that compensated for somehow?

It seems to ignore cold temps as a factor. That may also be why it doesn't update in the Winter.

I think the BMS is upgrading a bit now trying to coordinate pack health with your driving habits. My 40 kwh LEAF took 15 months to settle down. I lost 7% but then my degradation slowed to barely 1% a year over the last 7 months; a period that included all Summer, first ever 12 temperature bars and everything else that is supposed to be bad for the pack.

So it all remains to be seen how well the E Plus fares after a year. I am guessing 5% loss. About a third of Tesla drivers report a chunk lost the first year with the rate of degradation dropping way lower after that so not completely unusual. (guessing the other 2/3rds simply don't care)

But a few things about the differences between the 40 and the 62 which are HUGE and growing.

With everyone going to a charge by the minute billing system, its important to get all you can from your LEAF and it my quest to figure that out, some very interesting things have come to light.

Did you know that on cold (cold for us, cool for Midwesterners) mornings, a cold E Plus can charge THREE times faster than a TMS Bolt? 8-)

For those of us who are not yet up to speed on the acronyms, please define SOH and explain how to find it on a Leaf Plus S, which does not have the gadgetry that the upscale models have? I was familiar with the older Leaf's 12-bar Blues icon, but that is not very sophisticated and presumably there is a better more accurate battery state read-out..... Leaf Plus mostly charging at 120V for long periods of time. Thanks!
No LEAFs of any trim have SOH readings, only a bar graph representing capacity. There are 12 bars (or pips in your case) of unequal size (assumed in 40 kwh packs since none have left the building yet) ranging from 15% for first and last bars to 6¼% for the middle 10. All the SOH, ahr, etc readings you see here come from LEAF Spy; an app. If you don't have it and plan to stretch your range a bit, get it. It will be the best money you ever spend. Cost about $50

Hmm it's almost like OEMs should just rate the capacity after what it settles down to after that first year.

We own a 2019 SL+ (build date 3/19, purchased end of 5/19)

12/9/19 (current)
SOH: 94.37 :'(
Ahr: 166.47
QC: 39
L1/L2: 320
Odo: 14,823

This summer we got the battery pretty hot on a few occasions making some late summer "road trips" where we needed to charge along the way, possibly 5 times we QC when it was 80+ degrees outside. Our real loss has been in the "adjustment" we received last week that brought us down a good chunk (over 1.5%). I drive the car to work almost every day M-F 74 miles roundtrip charging only nightly starting in the middle of the night and ending just before I leave with a charge around or just above 80%. We've only charged the car to 100% when heading out on said "road trips" where we really need the range to get where we're going or make it to the next fast charger without going too low (below 15%).

TLDR: We keep the battery between 40 - 80% SOC the vast majority of the time, and try to avoid getting it hot if at all possible. Not sure why we're seeing such a sharp decline in SOH during the colder months here (in Ohio temps have been between mid 20 - mid 50 for a month).

This follows the exact same pattern as the 40 kwh packs did. My adjustments ended after 15 months with degradation slowing to a rate of less than one percent per 10,000 miles. This occured over the hottest part of the year so even heat and 12 temp bars didn't affect it. Soon 40 kwh packs will be ending their 2nd full year of operation. Interesting to see how they progress as I think the 62 kwh will follow the same pattern but with a more gradual slope.

How much (or range) do these batteries go for?
