How do you check a used EV's battery health? / Budget used Nissan Leaf shopper (often a second or teen car) planning a LeafSpy check

Budget used Nissan Leaf shopper (often a second or teen car) planning a LeafSpy check

What people actually reported
Showed 12 bars, but LeafSpy read 87% SOH
“for reference the 2015 I bought showed 12 bars and LeafSpy gave 87% SOH at 67k miles. So bars really don't separate a decent one from a tired one.”

Nissan swapped in a warranty pack within 2 weeks of purchase
“Mine was a cheap 2018 SV and Nissan swapped in a warranty pack under two weeks after I bought it, and the bars never hinted at anything.”

Used lot couldn't give Leaf SOH, only the bar count
“I called a used lot about a Leaf, and the guy didn't know what battery health even meant. The best he could do was the bar count, and that first bar is a big jump.”

Listings without bar display turned out not to be 12 bars
“I've noticed that when a listing doesn't show the bar display at all, it usually turns out not to be all 12. The couple of sellers I messaged confirmed that.”
