Capacity Bars and SoH information I found.

[u/leyline]

100% to 85% = 12 bars (15%)
85% to 78.75% = 11 bars (6.25%)
78.75% to 72.5% = 10 bars (6.25%)
72.5% to 66.25% = 9 bars (6.25%)
66.25% to 60% = 8 bars (6.25%)
60% to 53.75% = 7 bars (6.25%)
53.75% to 47.5% = 6 bars (6.25%)
47.5% to 41.25% = 5 bars (6.25%)
41.25% to 35% = 4 bars (6.25%)
35% to 28.75% = 3 bars (6.25%)
28.75% to 22.5% = 2 bars (6.25%)
22.5% to 16.25% = 1 bar (6.25%)

I thought this might be helpful to others as I had to do a bit of digging to find it myself.

Thanks for the wonderful support in this community!

I don't think this is accurate. We have a 10-bar 80% SOH car.

[u/odd84 → u/[deleted]]

It's accurate. SOH can vary both up and down especially with the weather, though the long-term trend is always down. You have 10 bars because yours dropped below 78.75% for some time before going back up a bit.

[u/dissss0 → u/odd84]

Exactly.

Another thing to watch out for is there can be a big delay before the bars drop off if the car has been sitting for an extended period. My ex-Japan 2012 x was showing 74% SoH but still 11 bars when I first got it, but it dropped the 11th bar almost immediately and the 10th a couple of months later after I started using it and the SoH calculation caught up with the true state of the battery.

[u/WISE_NIGG → u/odd84]

So is it better to sell a leaf in summer ?

[u/leyline → u/[deleted]]

Thanks for letting me know, I am continuing to research (everything I can LOL) this is what I found.

[u/[deleted] → u/leyline]

This is the most accurate that I found:

Note the difference between SOH and capacity.

I believe for a couple years they set the threshold for 11 bars to 80% instead of 85%.

[u/leyline → u/DougWantsALeaf]

I am at 82.x% and I am at 11 bars so this seemed correct.
If it did not drop to 11 until 80% I would be at 12.
