Alozzy is right about the SOH in my 2013 LEAF. It is at 89%
I have no idea how it will change in the next couple of months as winter thaws. Presumably somewhere between 85-95%
Do you believe that a BMS reset can set the SOH to any value, e.g. 85%, other than just 100%?

It was a general question, as some may believe such.
SageBrush wrote:Regarding the reset, I'm under the impression that the initial read is 100% and then with driving over a few weeks (maybe a couple of months ?) the SOH settles down to the pre-reset value.
Right, but not easy to do on the part of a Nissan dealer, i.e. putting miles on the Leaf. Yes, maybe an independent car lot if it had the time
and access to a Leaf diagnostic tool (Consult II) and whether that function can even be performed at the dealer level (without a logon to
Nissan corporate). Can you imagine what the press would do to Nissan, if it knew that were actually occurring at a dealer level?
SageBrush wrote:So it is not the SOH value in and of itself (unless it is 100%) that makes a reset suspect, but a SOH value considerably higher than normative for the peer group.
SageBrush wrote:My car fits the mold of a reset: It arrived with a LeafSpy reading of 64 Ahr and 99.6% SOH, and over 6 months lost 10% of each value. I don't think the car had an intentional reset because the dealer showed me other cars with poorer readings and the current readings are still quite good. All in all, we are treading in very poorly understood waters.
