Ahr and SOH are the only two I'd look at.
A new battery is 66 ahr, 1 bar lost around 50 ah, 2 bars lost around 46ah, 3 bars lost around 42 ah.
If the ahr are low and the bars are high they reset it, not a bad thing on its own but if you drop 4 bars in 60,000 miles or 60 months you get a free battery from Nissan, go over the months or miles and you don't.
You just want to know what you are really dealing with.
If the ahr is reasonable vs the bars on the dash then you can use SOH% as the easier to look at number on a 100% style scale but that number resets with the dash bars so use ahr to see if you can trust it then SOH% for a convenient percentage.
in table form
* Brand new - about 66.25 Ahr#
* Loss of bar 12 - between 53.75 AHr and 56 AHr
* Loss of bar 11 - between 49.75 AHr and 52 AHr
* Loss of bar 10 - between 45.75 AHr and 48 AHr
* Loss of bar 9 - between 41.75 AHr and 44 AHr
\#table is for 24 kWh packs, numbers would differ for a 30 kWh pack.
