Battery Milestone- 60k and 12 bars

[mtndrvr]

When we bought the car I was hoping to reach 40,000 miles with 12 bars and did what seemed reasonable to support the battery. When 40,000 came and went I thought maybe 50 would be possible. Well tonight the 2013 Leaf S crossed the 60,000 mile threshold with 12 bars.

Congrats! I'm going to make a wild guess and say it was built after March of 2013...

...and lived its life in a cool climate.

And is on the edge of the bell curve of battery quality. I doubt my 10/2013 LEAF's battery is quite that good but it also still shows 12 bars

Yes to post 3/13 battery
Yes to mountains of CO climate. However, not hearing about other people with 12 bars around the region.

Don't know about Bell Curve but I have used EVSE Upgrade since new and avoided Level 3. Charged to 100% after first month or two of trying the 80% idea.

..... Charged to 100% after first month or two of trying the 80% idea.

Interesting, do you use the timer to limit the time spent at 100%, have it reach 100% shortly before leaving?
My '13 lives in a pretty cold climate, I almost always only charge to 80% and use my departure timer and just turned 40k but has lost a bar
Note while a '13 built after 3/'13 it was purchased new in mid '14 with less than 100 miles but I have no idea how the battery was charged before I got it, could have sat at 100% for months on end for all I know. I believe when I got it(or shortly after when I got LeafSpy) it was only mid 90s SOH so obviously damage was already done before I purchased it

I occasionally use the timer and heat timer but only once a week tops in the winter. I bought mine in 2014 as well. The unit had 6 or 7 QCs on it when I got it and I have done one since then.

80% would not be practical for me on many days, especially in winter with heater and lights.

It is interesting how the different batteries respond. I was fortunate.

With these battery packs its all about the temperature they live in...which is why you should include location in your profile.
From subsequent posts, it seems as though you live in a "cool" climate...so that explains that.

While my location can no debatably be described as "cold" many months of the year, we also get many(and recently are getting many more) "hot" days in the summer, in the 90s.
I'd imagine a place like SF to be the best location for EVs, not too hot and not too cold Places in CO are probably good too.

Where would I look to see that quantified?
The variation in batteries in my and similar climates would need to be explained to accept that as the only explanation. It is clear that hot areas have had more capacity loss but am unaware of the data on the whole.
