Just got LeafSpy working today:

35,401 miles
82% SoH
53.65 AHr
96QCs 1347 L1/L2


Still have 12 bars... so when can I expect to lose the first one?

Edit: do you think my vehicle was reset?

Aaaaaaaaannnnd I'm down to 11.
What was your build month? From an earlier post you said it was a '14 from GA, right?

Those hotter temps really make a big difference. My stats from earlier tonight on my 5/2013 built '13 were:
AHr: 56.71
SOH: 86%
Hx: 84.86%
odo: 42,971 miles

I still have all 12 capacity bars (unchanged from when I bought it in July 2015) but I've been steadily creeping towards losing a bar. I expect to lose it before this summer's over.

I live in a hotter part of the SF Bay Area. Looks like my car was serviced in Santa Clara, CA by the previous driver. No idea where it really sat most of the time other than likely somewhere around there.
 
Here is my latest readings, this is an early 2013 build. I expect to lose my first bar sometime this summer.

AHr: 57.78
SOH: 88%
Hx: 85.5%
24QC & 1635 L1/L2
Mileage: 38,762
 
When I first got my Leaf at 10 bars:
09/22/2016
AHr:48.426
SOH:73%
Hx:53.32
L1/L2: 1452
QC: 0
Odo: 23924

Now at 9 bars:
04/27/2017
AHr: 47.219
SOH: 71%
Hx: 51.34
L1/L2: 1865
QC: 0
Odo: 31717.3

In service date is 10/2012, so it still looks like I won't hit 8 bars before 10/2017 unless this summer is incredibly harsh on the battery, but I don't think it will happen unless there is a miracle.
 
Hello everyone! I've been following this forum for a while but first time posting.
I have a 2013 LEAF SL with about 42k miles. Bought is used 2 years ago. I have 10 bars, but according to my latest LeafSpy numbers, it looks like i should be dropping one soon:
5/15/2017
AHr 46.00
SOH 70%
Hx 63.74%

Previous reading was on 12/15/2016 and is as follows:
AHr 49.64
SOH 75%
Hx 70.08%

I hit 5 years in February of 2018.

Thoughts?

Surprised it hasn't dropped yet. Mine has fluctuated as low as 45.3 (In Feb) to 47.2 currently. I lost my 10th bar last fall and am currently at 9. Like you, it's going to be close if we're going to lose the 9th bar before end of warranty. If I don't make it, I'm going to kindly ask for out of warranty support.

It actually did finally drop about 3 days after I posted this message.
 
My 2011 just hit six years and lost its 2nd bar on the original battery. It only has 25000 miles or so on it since I'm retired. I'm still on my original 12V battery, too.

I have a 2012 Leaf. I bought it used in September of 2016. I still have 12 bars and the GOM reads 75 miles avg (full charge) at 47K. Based on what I've read, I should have less life in my battery if it is the original. How can I tell if this car has a replacement battery? Thanx

I live in Maryland - hot summers and cold (not frigid) winter temps.
 
I lost my second bar and immediately took these readings. I have a 14 SL. Can anyone predict if I'll lose two more bars before 2/19?

AHr: 51.45
SOH: 78%
Hx: 70.69%
odo: 41,855 miles

It's definitely not that simple. Even if we had a detailed track record of your past stats, it depends on your climate (i.e. how hot this summer and next are), how many miles you are going to drive it, what kind of charging you are subjecting the car to, etc. I found that I was able to get some relatively accurate predictions after 3 bars and within about 7500 miles of losing that 4th bar, but it was so dependent on the weather that once summer was over my predictions got to be way off.
 
Mileage 7,293
Lost 1st Bar
SOH 78%
Hx 76.75
AHr 62.68

2016 SV, Living in Florida, leased this car 10/2016 and I suspect the dealership had it for several months before I got it. I usually QC in the morning for around 15 minutes, getting the SOC up in the 80% range. Didn't know I had lost a bar until I L2 charged overnight to 100% as I was going somewhere the next morning.

Going to Nissan to have them check both batteries.

Don't want to talk you out of it, but all they are probably going to do is get the same measurements you get out of LEAFSpy and then requote you the warranty terms (5 years, 60K miles, 4 bars).

If, as you suspect, you are losing bars at a faster rate than you should, then you will no doubt lose your 4th bar before those limits expire, at which time (and only at which time) they would replace your battery. I doubt they would do anything beforehand due to a suspected failure.

Having said that, you should probably check the full battery cell display. LEAFSpy will indicate weak cells (plus they will be pretty obvious in the graph. If you do have a small number of cells that are way below the voltage of the others, then that is at least something you could discuss with them.
 
Well if you are looking at the cell voltage display (96 lines running vertically) if you see any that are much shorter than the others (you should look at this when you are at a low stage of charge--when full they will be more or less even), then those are your weakest cells. If you see that there are only a few weak cells that are quite a bit shorter than all the rest, then those cells would be considered "weak" and could potentially identify a problem with those particular cells.

Otherwise if all the lines are all pretty close, then the degradation is across the pack as a whole and it's unlikely that there is any kind of manufacturing defect that would explain your loss other than normal degradation.

OK, what about blue vs red? I have 9 blue lines, the rest are red.

Blue vs red show which cells are "shunted" I believe. Shunting is used to balance the pack and is a normal operation. Don't worry about that. Just concentrate on the raw height of the bars.

You can also look at the Voltage Histogram chart. Ideally you want a very tall peak right in the middle, with a few smaller bars to the left and right. If you see a few outliers way to the left, that might indicate some weak cells (outliers to the right wouldn't be good either, but it's hard to imagine that would be a realistic scenario).
