My fourth bar is gone as of February 13, 2016. MY mileage is 66.5K, so only seven thousand between bars. It is getting to the point that range is a serious issue. I always need to charge to 100% to get about anywhere. I am using my Volt more and more as the public charging infrastructure is still sorely lacking.


I'm sorry you didn't make it to a free replacement.


On Aug 23, 2017, with 70.8K miles, I'm back to 12 bars after getting an out of warranty battery replacement. Nissan offered a 80/20 cost share so my out of pocket was $1617.08. I'm satisfied with the deal and very happy to get my range back to what it once was.

I wouldn't read too much into the Leaf Spy stats.

For instance, if you were to drive the Leaf, at highway speeds, down to low battery warning and then do a DCQC (not when it's hot out though), those stats would bounce up temporarily. Repeat that cycle a few times and they'll bounce up even more. I don't think doing that gives any lasting benefits though.

I think year to year stat comparisons, averaged over 3 or 4 readings spread over a week, would be more meaningful.

Another approach would be to keep detailed records (LEAFSpy will dump data to a dropbox spreadsheet making it easy to access & process). There will be small up & down perturbations as you say, but a trend line will definitely emerge and you can somewhat extrapolate out in time, with two caveats:

1. There will be seasonal differences...in the summer the slope of the dropoff will be steeper than in the winter due to higher temps.
2. The slope at the beginning of the battery's life will be somewhat steep compared to the mid-life. And then you will eventually get to a point where you will experience another drop-off. But for most of the lifetime the slope should be pretty consistent.

I don't have all the details from my car as I am not getting it back before the battery is changed out. 4th bar dropped somewhere around 42ahr though, and the battery is currently being changed at 41.4ahr, 57,007 miles, and 5 and a half years old. Surprised how quickly the battery went here in Virginia which I consider to be a pretty moderate climate. Hopefully the lizard battery holds up better.

5 1/2 years means your car had the original battery chemistry, before any subsequent tweaks. Did Nissan help you out with the cost at all? You are under mileage, but over the time limit of the warranty.

"Moderate Climate" is relative, I guess. I have been in VA in summer when it was hitting the low 100s for a week. It "cooled off" to 90-something overnight. To me, that's not moderate. Of course, the humidity affects people far more than batteries.

Unfortunately, the high summer temperatures seem to do the most damage to the battery. "Average temperate" is misleading because there is a huge difference between 70s all year and 40s in the winter/100 in the summer, even if they both average out to 75.
