I've been grabbing LeafSpy data periodically. Here's my battery degradation vice odo trend the last few months with a linear trendline projected.

so anyway... I'll go ahead and continue to keep track and post updated 62 kWh degradation in the future... obviously, represents a single vehicle datapoint.
Yeah, looks like we will be hearing from you around mid Oct. Right on schedule. That is just about when my next adjustment will happen. I am predicting Oct 10th so a few days before yours.

Thank you for the detailed report!

Do with of you have any updates on your battery stats? DaveinOlyWA, did your battery "adjust" as predicted? umdkevin, do you have an updated graph of battery stats? If things continued to progress as they did then I'd expect you to be right at about 96% now.

Thank you both for continuing to report your battery health!

There's some more recent data posted here: 'The 62kWh Battery Topic' viewtopic.php?f=9&t=30585

(I don't know why this thread didn't come up in my search before.)

Sorry for late reply but on my 40 kwh LEAF, I did NOT see an adjustment due in October and 5 weeks later, swapped it for my E Plus which has exhibited the same 90 day adjustment pattern.

Unlike the 40 kwh which was consistent with everyone I came in contact with around the world, some are seeing increases on the 2nd or 3rd adjustment. As someone mentioned, the larger pack means losing the same amount of capacity (ahr) but resulting in a lower percentage of the overall pack. I am posting my stats as of this morning in my sig.

I flatten around 92-93% would give the battery a 10% true buffer, which is what I think Nissan is doing. I think this is why in spite of dire predictions, we haven’t seen any 2018s lose s bar yet. We might see that next year though, after the cars fall off the bumper to bumper warranty.

NOT coincidentally; the difference in SOC between the GOM and LS is also about 10%
