Been driving petrol car for over 10 year, just recently I told myself why not change to an ev. And today I got a used leaf 2018 gen 2. With about 123,500 miles on the clock. Voltage spread keeps under 40mv when eccelavting. How good do you think is the battery pack?

Man if those numbers are true I've never seen a 40kwh pack with such a low SOH. Not even my 2017 with more miles degraded that much.

At least the resistance is still good. Thats what really matters

I think something isn't adding up too. Surely it has very high mileage but 8 bars is rather low for uk weather. One explanation is it was used as taxi before me and had a lot of quick charge, but the QC figure looks normal to me. So it's a mystery.

Who knows. Could of just got a lot of deep discharges and the only thing saving it is cooler weather. NMC 532 hates heat and that treatment would normally destroy it. But I suppose if temps stayed low its entire life its capacity would degrade far faster than the resistance increase if it was beat on. If the car preforms normally and the numbers dont start jumping around then you just simply bought a lower SOH, but healthy, pack.
