Capacity Loss on 2011-2012 LEAFs

[dhanson865]

We should be getting some instrumented readings from 2013 owners by now, particularly in Pheonix. Unfortunately all we have early on from 2011/2012 owners are reports of bar losses, so comparisons are difficult. Still, it will be interesting to see how the 2013s are faring.

I can't find the post but LeafFan in Phoenix has a 13 and has lost his first bar.

My AH actually dropped during fall/winter as I lost my first bar in Dec.

I observed an interesting thing with my 2013 compared to my 2011 pertaining to battery degradation. When my 2011 lost a cb, it was down 20% as my capacity gauge read 80%. Nissan said they 'tweaked' the chemistry in the 2013 bp, but I'm not sure how much it has helped yet because at 54.8 AH I lost my first cb, only 7800 miles/10 mos.

I was musing over the title of this thread... Remember when being down to 11 bars was a big deal? Now it is something that many of aspire to and can barely remember!

Thanks, jhm614 and dhanson865.

So it appears that LeafFan has lost a bar after a single summer, just as at least one 2011 LEAF owner experienced in late 2011.

Perhaps it does not have improved battery capacity degradation rates than the 2011/2012s...

Perhaps my memory is failing me (again), but I do not remember reading or hearing anything official that indicated that the 2013 battery was any better at degradation... The chemistry change was apparently for other reasons...

was an early 2013 as well.

I was thinking the same thing - the first 2013 LEAFs most likely got with batteries from Japan - it's possible that any chemistry tweaks in Japan are not the same as the ones in Tennessee - or they put in the tweaks later.

At the end of February (one year of two-year lease), I will post the BC %. Right now, with less than three weeks to go, I'm at 84% capacity. So the pack may end up being about 4% better/improvement over the 2011 pack which after one year/10K miles the capacity was 80%.

What were the start/end dates for the 2011? Your 2013 obviously benefited from only ONE summer season. In either case, you could make the argument that 4% (or maybe 3% by the time you hit your year) is within the "noise" tolerance; in other words, no real change/improvement in battery chemistry (at least not until the "hot pack").

Lost my first capacity bar today, finally. I suspect I've been flirting with this for quite some time.

Odometer: 48,500 miles
Capacity: 55.16 AHr
Hx: 69.25%

I guess it's time to update my signature...

oh oh, must be that "dry Summertime mountain climate" that accelerated your degradation. i think Steve was over 65,000 or so when he lost his but then again, he works on the shores of Hood Canal... marine climates always were amenable to EV power packs...
