I am guessing its the same cells out of whack all the time? That is a greater than .1 volt difference. I think that qualifies for a trip to the dealer. Another thing you could try is charging to 50-60% and let it sit 3-4 days if possible to see if that helps. Balancing happens all the time so the only reason for top end balancing is for greater range and the range improvment would only be a few miles at most.

On my 2018, I have a few outlier cells but not to that extreme but have only done 15 full charges including only 3 in last 3 months. Nothing to worry about since the range is sufficient and the risk of a high SOC far outweighs my desire to have a better balanced pack


Yes, same cells all the time. Keeping charge at 50% is hard, it's constantly in use. My daily usage on average at or slightly above 50% and I really doubt the dealer will respond to data from anything but official Nissan tools.
Thank you for advice though.

Update on battery replacement. Scheduled for Friday morning. Will post new specs afterward.

An interesting post on Facebook at https://www.facebook.com/groups/nissan.leaf.owners.group/permalink/1982145841856247/. He was down two bars and a Nissan dealer did "Recall PC630 LEAF 30KW BATTERY, NTB18 NISSAN RECALL PROGRAMMED HV BATTERY AS PER RECALL.". Now back to 12 bars. While it could be a simple reset it sounds like more.

Just got the car back from the dealer today. Turns out that they didn't start work on it until yesterday. It's only supposed to be 4 hr job. 4 days seems a little excessive. Anyway the old battery stats were 49.55 AH, SOH = 62.84%, and Hx = 55.33%. New battery IS 82.34 AH, SOH = 103.60%, and Hx = 97.07%. Interestingly enough, When I picked it up the SOH and AH were slightly lower (97% and 79.34 AH) then it was when I got it home (numbers above). I'll be checking it again after several battery cycles to see if it changes some more. I was told by the dealer that batteries are shipped with very low charge, just enough to power on the electronics and move the car to a charger. That could be why the numbers changed as the battery warmed up and I exercised it on the way home.

For those who are interested, the SN for the battery is 230SM1185H000875. According to the service adviser replacement cost of the battery was almost $10,000. I assume this was including labor. This sounds like a "Go to Hell" price to me although the dealer would normally make a profit on both the battery and labor and could discount it somewhat. Unless the battery is still under warranty I won't be replacing it at that price. I'm expecting this one to fail at about 90.000 miles and about 3 years from now while still under the original warranty. That will give me a 10,000 mi buffer on the expected failure. Still have over five years left time-wise so mileage is the limiting factor.

Talked with LEAF Tech and the reset is an unavoidable part of the process. there is no change in battery pack. The bars will disappear in short order.

Just as a reset will "restore lost capacity bars" the BMS will take a bit to learn the true capacity of the pack. So I would just record daily at same time (first thing in morning is best I think) and see where it goes.

FYI; this flakiness is at least partially resolved with the 2018 packs. The numbers no longer bounce around. Is this good...or bad? Not all that sure. The lack of bouncing tells me the 2018 is a bit less "truer" in its readings.

I put my VIN into the NHTSA website and it said there were no recalls for my car. I think this website only lists safety related issues so it may never show up there or perhaps it is too new. I'll be sure to get LeafSpy stats before and after my first annual battery review but that's still a few months off.

2017 S - 24k miles
SOH - 97 percent
Hx - 89 percent
AHr - 77.1

This is looking pretty good right? I think it lends credence to the theory that some 17s have good packs.

Did you just get your BMS "fixed"? There's a running discussion that this might just be a " reset", and that the BMS will relearn the actual capacity over time. So let us know if it changes quickly?
