Looking at purchasing used2020 Nissan Leaf SV Plus (certified from dealer). Only 10,000 miles, and only 70 charges---four of which were quick charges. As such, I was expecting great battery health, but LeafSpy Pro shows only 93.41%. That's more degradation than I would expect, and I'm wondering if I should be concerned that the previous owner did something wrong, that battery if premature degrading, etc. The other thing----LeafSpy's voltage histogram shows fairly uneven bars, including a 30mv difference. I'm reading some people saying 30mv is cause for concern. Other people say 50mV Here are some other particulars: SOH: 93.41% 400.62V SOC=97.1% AHr:=164.78 SOH=93.41% 402.56V Hx = 104.21%
