I should put both of those in quotes.. by "capacity" I mean the Ah capacity we discovered in the Group 1 active CAN data on line 6.. 3rd, 4th and 5th bytes. Displayed on the LeafDD page 2 "C" and at the top of the ELM voltages page. By "health" I mean a 16 bit number I've been playing with... ("H" on the LeafDD page 2) Also in Group 1 active data but on line 5 on the 3rd and 4th bytes. Like the Ah capacity, this seems to track fairly well with actual usable capacity only this seems to be in the form of a percentage of original capacity.
This may end up being a more useful indicator of actual capacity (and possibly the number used to display the capacity bars.. which of course factors into the warranty). What I find interesting is that on the two 2013 cars I've tested so far the health percentage was over 110!! Could it be the bar of expectations has been lowered on the 2013s so they have to dip a little lower before the warranty kicks in? Will this number change if we update the software on the 2011/12 cars as Nissan intends us to do? Perhaps we could display this in the ELM software as well and get more readings. We'll have a dozen or so new LeafDD users by this time next week as well.
Here is some data from other cars (some 2013s) as well as multiple readings from my car..
