Admittedly, the battery was replaced about a week ago under the capacity warranty.


Was your early or late 2013 production? Sorry if you posted the info before.


We bought it used in March of this year for about $6,000, so I am not positive, but looking at the sticker on the door, it appears to have been made in February, so we were just in the nick of time for the warranty.

Is there a difference between early or late? I haven't seen anything about that.

Posts I've seen show that post April build have a newer battery that should last longer. My friend has a April build one that seems to be degrading at a fast rate. We were hoping the last bar will drop before the warranty expires. However it currently looks like it will miss and drop after 5 years. Congrats on your purchase and replacement! Steal for 6k!

I'm very curious what folks think of this.

I have only lost 2 bars. However, my amp-hours are down to 43.57Ah, SOH 70% and Hx 45.59%. Plus the maximum I can get into the battery is 15.9kWh.

Shouldn't I have lost the third bar long ago? I think some folks have lost their 4th bar at this point. I'm thinking Nissan has done something with my BMS. that or LeafSpy Pro is reporting wrong.

Any thoughts?

BTW, i have 45,023 miles on it and it is a 2015 SL.

It would appear you should be about to lose your 4th, not 3rd. But have seen some weird batteries before. Like losing 2 with a few hundred miles. I would not be surprised to see you lose TWO at once! Now, hasn't happened that I am aware of but have gotten into the habit of not eliminating any possibility

Is this a new vehicle you recently purchased?

It has been known that either intentionally or unintentionally (I think a prolonged dead 12V battery will cause this) the "bars" get reset and the car relatively quickly (but not immediately) figures out how many bars it should be at, so you will lose a bunch in fairly rapid succession. I think this is the phenomenon that DaveinOlyWA might be referring to.

Do you mean 15.9 kWh from the wall, or do you have some way to measure actual energy into the battery ?

you may have a bad cell. How much is the cell variance in mV on the Battery Cells page in LeafSpy?

Need help, I'm at 49.44 ahr in a 14 leaf with 48455 miles and two bars gone. I'm going to hit 60k before 5 year warranty is up. What are my chances I'll get a replacement under warranty? I live in Austin, so it's hot most of the year.

Hmmm...very disappointed with my 2016 LEAF battery. Lost my first bar about a month ago with only 13027 miles!!!!

Here are my LEAFSpy stats from that day:

AHr: 64.037
SOH: 80%
Hx: 76.8
L1/L2: 300
QC: 61

The car was a dealer demo vehicle, so I bought it 12/23/16 with 1915 miles on it, and 39 QC's on it (lazy bums must've only ever plugged it into the QC), but it had 100% SOH and 96.31 Hx when I bought it, so it looked pretty solid at the time.

Here's a plot of my SOH and AHr over time. Sorry, but I'm missing about 2 months of data during a time when quite a bit of capacity was lost, but I think the slope of those stats was reasonably constant over that time.

I exceeded the 60K mark by 1490 miles in my 2012 LEAF :evil: The way this one is going, I'll probably hit it by 40K.
