Night leaf, is yours a 2018 or 2019 Leaf?
I am curious if the 2019 40 batteries are doing any better than the 2018 40 batteries.

Wow, look at that, really flat for 10 months. Any changes in charging habits? I wonder if the leaf moves between estimated and actual SoH.

There is no readout for actual SOH. Can only be estimated in several ways.

Most everything around here is wet during the rainy season. And the rainy season is long.

No change in charging routine. I do baby the battery, keep it between 30 and 75%, charge it early morning so the battery can cool down over night and no QC charges. Last summer here in Atlanta it was warmer than normal, but even so the battery according to LS essentially stop degrading. I'm really curious to see what happens this summer. Also the big adjustments that have been occurring every three months appear to have stopped.

I saw the exact same thing on mine. months 1-14 I lost 7%. Month 14-21 lost less than ½%

My slow loss period included the entire Summer which meant MUCH higher temps (after Rapidgate update, it was easy to hit 10, 11 TBs) and more driving.

Good news. you give me hope that my Plus battery will flat line in the 96%-97% range now that it has settled in. I am also trying to now keep the battery in a 20-90% range, though I occasionally make a mistake.

Dave, your Plus battery seems to be doing even better.
