Looking at a used 2017 Leaf S, there are 10/12 bars which isn't bad ... but using LeafSpy SOH is 74%, and cells 1, 3, 5, 20, 24, 25, 27, 33,36, 39, 41, 43, 79, 81 and at least one more show up as "weak cells" during our short test drive. The pack wasn't fully charged before our test ride (LS says 94.6% SoC). Just how bad is this? Anyone have any luck with taking a used leaf with such a pack to a dealer for a factory replacement or does the warranty only start kicking in at 8/12 bars or some catastrophic failure?
