Bought a used 2012 SL recently. One month and 1,390 miles later LeafSpy Pro battery stats show AHr= 60.71 SOH= 92% Hx= 90.85%. No QCs at all (I keep meaning to) and 408 L1/L2s. Wait, 408 charges? If I count the days I've owned the car, I've charged it 32 times for an average of 43.43 miles per charge. If I subtract my 32 charges and the 1,390 miles driven, I get 376 charges for 2,578 miles which = a charge for every 6.85 miles. Hmm what can that mean? So far I'm happy with the car, the price was right, and it came with an L2 EVSE which I now use at home.
