I know this thread is a little old, but i just got to the point where i need to measure my real battery status, and not depend on the stupid, lying "bars". 2011 Leaf with about 36k on it.
I just bought the OBD II reader and the software. Here is what i get, remembering that my Leaf has 9 bars and has shown 9 bars for more than a year, all while range has been steadily decreasing. I get about 48 miles to a charge now, based on driving in Eco mode, and going side roads and no freeway.
Fully charged here are my readings:
GIDS: 183 (65.1 %)
Remain: 14.2 Kwh
Miles to 5%: 51.6 at 4 mi/kWh
Battery cells image looks fine. All are between 4.074 and 4.092.
So, to me this means my battery is only at 65% of original capacity. But my understanding is that 9 bars is about 70%, so i would assume my bars should be at 8 or less easily.
Nissan says they wont even talk to me about a battery replacement until it hits 8 bars. My opinion is that they've just modified the software to not show 8 bars till as late as possible.
Any input/insights/feedback is welcome.
1) how in the hell can you be at 40.96 ahr and still have 9 bars??? have you done any recent SW updates? you are pretty much the lowest 9 bar reading I think I have ever seen or very near it.
2) your cells are NOT fine. an 18 mV delta at full charge shows very poor top end balancing. Could be a result of degradation (in my 2 LEAFs, I have had very little experience with that) a well balanced pack would be under 10 mV
either way, check the battery replacement threads. most are losing their bars in the 41-42 ahr range
