Since I apparently confused you, I edited my previous post to clarify that percentage reduction in Hx somewhat tracks with the increase of internal resistance over time. Also, I was wrong--the 2011 replacement battery (original chemistry from Japan) did start at 100.00% for Hx and 100% for SOH with initial readings taken across the street from the dealer (although the terms were not defined the same in the older versions of Leaf Spy so Hx was called Hlth back in 2013). SOH was still 100% after the 12-mile drive home from the dealer, but Hx dropped to 88.08%. The Leaf Spy readings at home with the odometer indicating 29,382 (29,370 when battery was installed) were: AHr=65.60, SOH=100%, Hx=88.08%, QC=30, and L1/L2=859. The morning before the crash on January 4, 2015, the Leaf Spy readings were: AHr=53.94, SOH=82%, Hx=66.27%, QC=57, L1/L2=1408 with the odometer indicating 50,416 miles. The 2015 started with the following Leaf Spy readings on February 7, 2015 (across the street from the dealer): AHr=64.38, SOH=100%, Hx=101.25%, V=391.37, Odometer=9, QC=1, L1/L2=4, and SOC=85.7%. The last readings I have for the 2015 were on August 10, 2019: AHr=39.84, SOH=63.44%, Hx=34.14%, V=388.32, Odometer=82,434, QC=340, L1/L2=1483, and SOC=80.9%. As noted in other threads, the 2019 started with AHr=175.15, SOH=99.29% and Hx=98.19%. Hx initially increased then slowly decreased as the car was driven and is presently at 102.12%. Unfortunately, I don't have any experience with the 30 kWh or 40 kWh batteries.
