My 2016 leaf has all 12 battery bars but leafspy is telling me that the AHR is 70 and SOH 88
Why this discrepancy?
12th bar is dropped at about SOH 85%, so 12 capacity bars makes sense.
Variations of +-2% are fairly common, at least in my experience. Graph SOH for a while. Dropping a percent or two in summer has been common for me, with some recovery in the fall. Dropping more than 3% is pointing at a possible reset. Rapid loss of 10% or more is pretty convincing.
