### First Post - Leaf Spy Question

Hi everyone! First time poster. I'm looking at a used Leaf. I had the dealer run the Leaf Spy app and have attached a screenshot of the data. Can someone help me decipher the info?

The battery capacity is down a bit (almost ready to lose first capacity bar since it has about 14% capacity loss). The screen shot was taken with full charge.

The difference between the SOH and Hx seems pretty high. SOH is a long-term calculation of "State of Health" while Hx is supposed to be more of a snapshot of the current battery conditon. My Hx is usually only 3-5% below my SOH. The Ahr reading also seems low for that SOH. Compare to mine in my signature.

I'm not enough of a sage to explain what this means, but I'm not encouraged by your numbers here. Anyone smell a BMS reset that is mid-way to returning to true values?

I notice a lot more difference between SOH and Hx with my 2015 than with my 2011. SOH appears to be a percentage of new battery capacity in ampere-hours while Hx appears to be inversely related to internal resistance (increasing internal resistance yields lower Hx values).
