Mine dropped on May 31st. I wanted to wait until the end of the summer before getting replacement so drove it for over two months with 8 bars. I dropped it off at the Dealership last week. Approved. (Multiple Nissan owner, purchased Leaf 2 years ago with 36K miles)

No other data available. I joined forum due to 4th bar loss.
If you don't mind, can you get Leaf Spy and pull your Ah, SOH, and Hx values off of it so we can have it for statistical information? (Along with year model if you don't mind.)

I'm assuming, based on what I have read, that I'm just weeks from dropping the 4th bar?

AHr 41.90 SOH 64% ODO 36391 HX 57.40
2013 SL

There's a lot less data so far on 2013s, and at least the Hx numbers differ substantially from 2011/2012. But from the 8 reports I've been able to find, the average Ahr at drop for 2013s was about 41.5, and average Hx was 56.4. The highest Ahr at drop was 43.3, and the lowest was 40.05
(The average Ahr at drop for 2011/2012 is about 42.5)

Just dropped my 4th bar. Could not be happier about it. Here are my Leaf Pro Readings.
AHr=41.25, SOH=63, Hx=56.34
2013 SL with 36,680 miles

Everything that I can see shows that SOH is current AHr / 66.25 and calculated in LeafSpy. 66.25 AHr is the assumed capacity of a new battery.

FWIW, Turbo3 said that SOH is read directly from the car.
(The car may be calculating it based on the number reported in Ahr, but LeafSpy reads SOH directly.)

I looked into my Ahr & Hx vs. SOH numbers a bit, and there's some hysteresis. There is no clear cut-point at a specific Ahr for, say, 66 SOH. I've had ranges of Ahr readings during which the car reported either 66 SOH or 67 SOH, for example. Tried to play spot-the-trend but didn't see anything obvious. You're right, though, that it seems well correlated to Ahr / 66.25.
 
I bought a 2012 with 37000 miles and 9 bars back in June. Took it to dealer and found out warranty will expire on October 10. LeafSpy shows SOH T 67% and 44.45 AHr. Been quick charging once a day for the past few weeks but not much change. Really hope I'll get to 8 bars before warranty expires.

I don't think there's any way you'll make it, I'm afraid. The highest reported Ahr at 9-bar drop for 2011/2012 is 43.56 Ahr; dropping nearly 1 Ahr in under 30 days seems pretty unlikely.
(I'd be curious to know how your LeafSpy readings changed with quick charging; my own experience with moderate quick charging is that it temporarily raises the Ahr values, and though they eventually drop again, I didn't return to my previous decline trajectory; IOWs the net effect for my car seems to be a delay in reaching lower Ahr values. But, others disagree on this effect.) FWIW, I'm at 43.65Ahr on my 2012, and I have doubts about failure before my February expiration.
OTOH if you got a car which was "reset," there have been reports of very quick and dramatic drops as the BMS recalibrates itself fairly quickly.
My best suggestion would be to look at your readings since June, and extrapolate from there, to see where you're likely to be at in October. if it's in the 44's, no way.
On the upside, there have been several reports of Nissan doing out of warranty replacements with some degree of cost sharing.
 
You are right, my AHr actually rises after quick charging, and hasn't really changed much since June. I was very careful when I first got the car, always in the garage away from heat and only charge at home at night. Just started quick charging last month. Will call Nissan to find out if they will do any cost sharing if warranty expires. I sure hope they will because 40 miles per charge it's hard to work with.
 
My 2012 LEAF is killing me. Warranty is up Feb 1. I had been on a fairly steady downhill path, which extrapolated to a new battery, all things being equal. Then a quick charge session bumped me way up, followed by a fairly nice precipitous decline, then a rise, another decline which edged into 4-bar-loss territory, and now on to another rise - back to pretty much where I was 30 days ago. :/

I don't understand what's suddenly causing my numbers to, in the immortal words of The Smiths, oscillate wildly. :)
Hoping for another one of those steep drops after the inexplicable increase. This is one complicated black box they've built!

My suggestion is to ship it (or drive it if you've got enough miles) to AZ or FL for the winter. ;) Otherwise, you've pretty much got no chance in MN. Maybe if you kept it in a heated garage and drove the 'ell out of it, but even then you're battling against ambient cold inertia.

Yep. I wonder, does anyone have daily leafspy stats for a cold winter? Curious to know what to expect. I've seen daily graphs for happy CA cars but nothing from the frozen North.

Well, not from the frozen North, but still, my Ahr values basically stay the same from Nov 1 to Mar 1. I monitored them in 2015 & 2016 but since they were flat, I didn't bother with 2017. Even though I only have two data points for 2017, the downward slope hasn't changed much. My overall graph since 7/14 has a slope of -0.0072 Ahr/day (I think) with R2=0.969. I'll take another data point Nov 1st, but don't expect to lose my 4th bar until Spring 2019, maybe Fall 2018.
 
It finally happened!

Apologies for all the drama along the way. :oops: We had 3 unseasonably hot days here in MN, around 90F or above. I had my hopes, but that Ahr value just wouldn't move down - in fact it moved up a little during these hot days. Extreme frustration. But then tonight, on the way back home, I saw 8 bars. I don't think it had dropped much before I noticed, but at any rate my values were just not moving much over the past few days so these should be about right:

2012 SL, built 8/12
43.50 Ahr
45.25 Hx
40,618 Miles
28 QC / 2715 L1/L2

That's the third-highest Ahr I've seen, behind JPVLeaf (43.56) gbshaun (43.51) so I consider myself pretty fortunate. Warranty was up Jan 30 2018 with the cold winter looming.

Battery temp when it dropped was around 95F, and 89F ambient at the time. (Values edged up slightly by the time I took this pic).

Congratulations! You're one person who is happy (currently) with global warming.
Hah, no, not really. But I guess this did help a little. Will be glad to stop driving the LEAF in circles, though, which did feel a bit dirty even if it was solar/wind powered.
Now to find a competent dealer/shop/tech in MN. "Have you done a LEAF battery replacement?" "Do you mean the hybrid battery?" "Oh dear..."

The Leaf is currently at the dealer getting the new battery pack installed. Here is a photo of the pack before it was installed in the car.

New Battery Pack is in and currently get approx 101 miles on a full charge. Compared with only 59 miles on a charge with the old battery pack. Attached are my Leaf Spy pro reading with the new battery pack vs the old battery pack.

I went out and checked my Leaf again today. I think the 4th bar should have dropped by now, but it is still holding on.

The vehicle was manufactured in January 2013, spent it first two years in Georgia, was auctioned after lease return and brought to Las Vegas. I got it in March 2015. It dropped the first bar in October 2015, the second bar in June 2016, and the third bar in November 2016.

Aug 12, 2017 - AHr=39.25, SOH=60%, Hx=53.34%, odo=25,451 miles, QC=4 L1/L2=2119

That's what worries me for mine - we have lots of data about when people did lose the 9th bar, but not a lot of data for those with 9 bars still holding on. I wonder how many low Ahr batteries still have 9 bars ...

I've been able to find about 8 reports of 2013s dropping the 9th bar; the average was 41.55 Ahr and the min was 40.05Ahr. I bet yours goes soon, though...

My fourth bar finally dropped.
Oct 12, 2017 - AHr=36.81, SOH=56%, Hx=49.75%, odo=25,670 miles, QC=4 L1/L2=2242

Replacement traction battery arrived on October 19th and installed this morning. I took this reading just before I left the dealership.
Oct 20, 2017 - AHr=65.40, SOH=100%, Hx=100.00%, odo=25,771 miles, QC=4 L1/L2=2262
 
Hi all, I am new here and would appreciate input from this experienced crowd. I am considering purchasing a 2013 SL w/ Bose currently at 32,300 miles and 9 bars. I don't know the exact month the warranty expires. The owner, who works for a Nissan dealer, said a little less than a year (I can get more detail). I live in Phoenix, though it's now "winter" (i.e. in the 80's and 70's vs. the 100's). Is it worth the risk to spend about $9k and hope it drops to 8 bars?
