That's a free estimate of the overall condition.
I know that on a ten year old Leaf you can tell the rough capacity loss
by turning on the 'ignition' and looking at the battery gauge in the
instrument panel. There's a 12 bar display, for both current state and
total capacity, 8.3% per bar.
Individual cell numbers, comparable to testing compression in all
cylinders of an IC engine, that'll take a diagnostic tool and some time.
