Anyways back on topic here...what is the highest mileage 2018 MY anyone here has observed? Anyone hit 80,000 miles? I believe i recall seeing a couple reported at 40,000 miles+ without any degradation past 88/89 pct SOH so far...

One FBer has over 60,000 miles and SOH is just under 91%. This was a while ago. I will have to check to see what his recent numbers are
2011 SL; 44,598 mi, 87% SOH. 2013 S; 44,840 mi, 91% SOH. 2016 S30; 29,413 mi, 99% SOH. 2018 S; 25,185 mi, SOH 92.23%. 2019 S Plus; 4411.3 mi, 96.88% SOH

I think mileage is less important than climate, how you charge it, and time.

And it seems lately there is no concensus on best practices other than limiting extremes. We fast charge our 2016 SV half a dozen times a year, keep the charge between 40 and 80 percent. Once a month charge to 100 percent. Mostly charge on 240 at either 12 amps or 27 amps depending where I park Occasionally hit 7 temp bars but mostly 5 to 6. We don’t have Leaf Spy. I have no idea on our battery health but I don’t think our range has changed much over the years. I and our neighbours seem to have similar results with our similarly aged leafs. Meh. Think I’ll just keep doing what I am doing. The car is freakin bulletproof.

If these data points are correct with quite a few 2nd gen LEAFs reaching 40K-60K-80K miles then it would appear that the chemistry of the 18+ MY units is even better than the 15 MY (which was regarded one of the best). I know there have been 15 MY units that have reached 100K+ with no bars lost but that does not appear common. We certainly need more reports to truly observe if this is true.

Fact is I have not seen a single photo posted of the battery bars showing any missing on any 2nd gen unit..doesn't mean there are not any...just I would have expected to see many by now from different hot locales.

Well, part of that is simply the car is still quite new approaching two years on the road. The other part is simply cycling a bigger pack. That first bar might still be 15% (since none have left, we can only speculate) but represents a bigger chunk of kwh's.

The next 6 months will be the telling factor;

We see bars dropping so the degradation slowdown I and others saw after a 7-9% loss was temporary.

We don't see bars dropping except in extreme cases (Phoenix, etc.) which means we see what happens by next year

No one loses a bar because they all bought Tesla's. :roll:

I would say I wish I had more time with my 40 but... I DON'T!! 8-)

Hi all, just joined forum and starting using LeafSpyPro 2 weeks ago. Live in Northern New Jersey.
2018 SL
Manufacture date 8/18, Purchase 10/18
14,712 miles

Battery Stats
SOH 94.47
AHr 109.045
Hx 109.11

Update on 2/9/20, sudden drop in SOH
Between 1/02/20 and 2/07/20 SOH dropped from 94.48 to 94.43 at a linear rate. I have never QC’d, only level 2 at home. Temperatures for month mild for northern NJ winter avg 30s-40s. Car kept in garage overnight.

Between 2/07 and 2/09 over the course of 3 short 10 mile weekend trips dropped as follows:
2/07 - 94.43
2/08 - 94.36
2/08 - 94.29
2/07 - 94.15
Definitely odd drop. Stable outdoor temperature and no change in driving or charging habits? Makes you wonder about a forced correction algorithm in the BMS?
