My total adjustment was about .71 ahr

My fifth adjustment finished recently, and was by far the smallest yet. I've had my Leaf+ for a little over a year now and have just under 15K miles on the odometer, and am at 95.5% SOH according to LeafSpy.

Adjustments and weeks from ownership:
8 week 1 aHr
20 week 1.3 aHr
33 week 1.37 aHr (I probably just didn't catch this one exactly when it happened)
44 week 0.25 aHr
56 week 0.05 aHr
This does indicate some considerable progress from the 40 kwh pack.

For comparison, here were the stats for my 40kWh Leaf when I traded it in:
13,500 miles with 95.69% SOH, driven on roughly the same trips/commute, though the battery pack at times got MUCH hotter.
5 weeks 0.85 aHr
17 week 0.4 aHr
29 week 1.0 aHr
41 week 0.0 aHr

So in my case, at least, the two batteries have had very similar degradation. The 40kWh battery was just a bit worse, but our longer trips were harder on it than on the larger battery since it heated up so much more with repeated fast charging.

It doesn’t seem like heat is nearly as bad on the newer chemistry.

Right, "seem" is the appropriate verb.

Well it won't because the Plus pack has more cells. Its like taking a space heater used for heating a room and trying to heat the house. The house will get warmer but not very much and not very fast. The reality is we are charging 2019 batteries with 2010 technology in most cases.

If you are lucky enough to be near the faster EA stations, you get a break. The rest get 120 amps...

Are you talking about apparent capacity loss?

If so, Leaf Plus hasn't been out nearly long enough. It took (IIRC), two summers in hot clients for '11 and '12 Leafs to show capacity loss in the form of capacity bars gone. Back then, Leaf Spy didn't exist.

Leaf Plus has been shipping not much more than a year and Leaf in the US has been getting its butt kicked by Tesla in terms of EV sales. And, many more EV/PHEV choices are on the market now than back then.

think he is referring to how hot the pack gets when quick charging

My 2011 dropped down to 10 capacity bars after about 12 months and down to 8 bars after a little over 2 years. The 2015 was MUCH better, but was at 8 bars with several weak cells when I traded it in after 4-1/2 years and 82,436 miles. It is too soon to tell for the 2019, but initial indications for the 62 kWh battery look fairly good based on Leaf Spy readings after 9 months and 16,185 miles: AHr=171.35, SOH=97.15%, HX=111.52% (initial readings on 8/11/2019 at 64 miles were 175.15, 99.29%, and 98.19% respectively). (171.35/175.15)*100=97.8% of original capacity. The first two 90-day adjustments were small increases, but the last one was a decrease in April. That decrease may be due to fewer miles per day with less freeway driving and more days between charges since I started teleworking in early March.

Well this is not the adjustment I had hoped for. Battery has been stable for 2 days now, at 94.66%, which is 1 full percent lower..ouch.

The battery took 3 days for the adjustment.

Pre adjustment: 95.63%

5/14 95.37%
5/15 95.27%
5/16 94.66%
5/17. 94.66%

I had no charges to 100%, 0 fast charges and maybe 1000 miles since the last adjustment due to lockdown.

So confounded to say the least. Let’s see how the summer goes.
