Lost my first bar today on my 2016 SV 30kwh Leaf.


Mfg date: 12/15
Mileage: 19,648
SOH: 80%
AHr: 64.20
Hx: 75.86
SOC: 97.4
GIDS: 293
22.7 kWh


Not too good as I'm in the Twin Cities area (cool climate for the most part). Obviously this battery is one of bad batteries manufactured late 2015.

Speaking of which. a 30 kwh LEAFer got his pack replaced under warranty and hit initial LEAF Spy stats are dead on target for a new 24 kwh pack...

more to follow, I guess... haven't heard anything from him lately.

Yeah. Very strange. For anyone following, it's at https://www.facebook.com/groups/nissan. ... 951579506/. I haven't had time to follow.

San Mateo's much milder.
Yep - Dublin does get quite hot by bay area standards :) As such though, I would not consider a few days of 100 degree weather and a few days of 30-33 degree weather as torture of any kind on the Leaf's battery....:) 90% of the days of the year, the temperatures are fairly moderate...

I think, most 2016/2017 30Kwh battery packs will lose a bar at around 30,000-35,000 miles...as such the loss is in line with the warrantied battery capacity of the 30Kwh pack..it will likely lose it's next bar at 65,000 miles and another bar around 105,000-110,000 miles..

The GOM has been a bit unstable the last week..it has been showing anywhere from 92-100 miles on 100% charge on different days..the varying temperatures, and some of my varying driving style are probably causing it...but I am guessing, 95 miles is the updated range of my 2016 30Kwh pack..down from the 107 miles original EPA rating...

I have a 86 miles round trip commute with access to a work place charger, so too early and hard to tell what is end of useful life for this battery pack in my use case.

I just wanted to add my data to the mix.

2016 SV - 30kW
Build date: 11/15
Purchased: 3/16
Miles:26000
Location: Hawaii

Battery: 3 bars gone - 63% SOH

I'm expecting to lose my 4th pretty soon and I'm looking forward to getting back my range.

Wow! Are you parked for long periods at above 90% state-of-charge? Being so close to the ocean, I can't imagine the car ever seeing 100+ temps, unless you QC often?

Thanks for sharing. Do you have any other data points ?

I charge it daily using my L2 charger to be able to make my daily commute. It only has 1QC that the dealer must have done before I purchased. The air temps are usually 80-90 and I have never seen my battery temp gauge show more than normal.

the degradation we are seeing for 2015 build 30 kwh packs are not heat related. How would you explain a pack in OR with near similar issues?

That's why I was asking about whether the vehicle was kept at a high state of charge. I didn't know about the OR one.
