Two dealers now have told me that they do not have a way to give me the theoretical capacity but plugging into the car's computer. So if this is true how do they determine of the battery is below the threshold?
There's a document they have to follow and it requires a scan tool.

Recent data points from the car's energy page:

miles - date- - - display #'s - - calc kWh
81697 -6-12-20 -58% -10.2 -17.59
82314 -6-29-20 -81% -14.0 -17.28
81557 -6-9-20 -61% -10.9 -17.87
83298 -7-23-20 -63% -11.1 -17.62
(not sorted correctly...)

Are these numbers going to be that much different from what one would get from TorquePro or the dealer's Scan system?
Used '14 2LT w/ DCFC. +83k miles.
Mostly free charging! Only one LONG visit to the shop....
GM needs Modern Troubleshooting tools for Modern EV's.
3 step Trouble Tree, 1st try car died again, 2nd try not covered / cost $800. 3rd try fixed the problem.

Norton - I have a bigger question! How does one drive a 2014 Spark EV for almost 83k miles and still have a calculated battery capacity of 17.62 kWh when the battery capacity in my 2014 Spark EV w/o DCFC and 24k miles on the ODO is already 15.0 kWh ???? What is your secret? :D
