No idea. Leaf Spy doesn't "test" battery health. It merely renders traffic on the CAN bus and I guess can make queries and render the responses.viewtopic.php?p=497564#p497564
has some historical posts about the origins of SOH and Hx in Leaf Spy. viewtopic.php?f=44&t=14285&p=516444&hilit=nissan+meaning#p516444
has a reply from Turbo3, author of Leaf Spy
You can only hope there are similar enthusiasts for the EV/PHEV you're interested in, that they've written an app and that the data can be retrieved by some method.
