Difference in SOH between LeafSpy and LeafStat

Sat Oct 14, 2017 3:57 pm

2015 S w/QC. 45k miles, still got 12 battery bars for now.

Question is... why does SOH reading vary between LeafSpy and LeafStat?

LeafSpy shows SOH at 93%.
LeafStat shows SOH at 87.52%

Is LeafSpy the authoritative number, and LeafStat is just off its rocker? I've always had different SOH readings between the two apps, with LeafStat consistently showing lower number than LeafSpy, but don't know why.

Anyone?

I've never used LeafStat and had to look it up (https://itunes.apple.com/us/app/leaf-st ... 67018?mt=8). LeafStat AFAIK isn't widely used.

Neither is "authoritative ". AFAIK, Nissan has never released any public documentation regarding any values on the CAN bus or that can be retrieved via queries.

viewtopic.php?p=497564#p497564 has pointers to some posts from Turbo3, author of Leaf Spy regarding the values currently labeled as SOH and Hx.

I found viewtopic.php?f=44&t=16670&p=370844&hilit=soh+hx#p370844 in a LeafStat thread...
