Tom, it seems this warranty is tailor-made for your LEAF! Do you think you will need to park it for a little while when you get up in the high 50Ks to let that last bar drop?

Since it is a four year/ 60K lease and is going back at the beginning of March, there is probably no incentive as I expect I will be just a tick under 60K at the four year mark and the fourth bar will likely have dropped a few months before that. If it does drop the fourth bar while I still have it, I'm going to make then replace the battery even if there is only a month left though!

Considering all the crap Nissan has put people through re batteries, I'd probably demand they replace it at 59,999 miles and/or 3 years, 11 months and 29 days!

...In conclusion, my current Ah reading of 53.6 is 81% of a new LEAF's ~66 Ah. My energy used to charge is about 78-80% of what a new LEAF pulls from the wall to charge from turtle to 100%. If anything, the car is over-estimating capacity, not under.


I've posted a reply, on-topic, at:

Collecting data:Off-the-wall power for turtle to 100% charge

viewtopic.php?f=31&t=6876&p=365452#p365452

The real question, as far as I am concerned, is what are the results for LEAFs with far more miles, that have experienced higher ambient temperatures, or have seen far larger gid/ capacity bar losses than drees or my LEAFs have.

Have any eight-capacity-bar LEAF reported either constant-speed range or recharge data, since the one LEAF in the Tempe range test, which with~39% gid loss, only range-tested (with 59.3 miles at ~62 mph, very roughly) ~20%-25% capacity loss?

I understand folks are mostly concerned with getting your own batteries replaced under the 5/60 warrantee, but it would be very helpful for those of us who may not receive any warrantee coverage, and are still wondering (thanks to Nissan) what our replacement batteries will cost, if you could help us to know when we can expect to need to pay for one, by posting recharge or range test results.

Sorry to hear that. My SOH is waffling between 81-82%, so I am guessing I'm not too far away myself. Just cleared 53K miles yesterday (my third LEAFiversary!).

I'm turning in my Leaf today for the end of the 3 year Leaf, I was really hoping that 4th bar would drop before turn-in, but it looks like it's going to hang on.

I'm likely going to hit 60k miles in September, I wish I could lose 2 more bars before that but there won't be such luck :(

Would you have bought the car end of lease if you had a new battery?
Any consideration to buy out and get a new battery by end of Summer?

Or just time to move on...
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.
LEAF traded at 45,400 miles for a RAV4-EV

Well, even with all my battery babying and gentle driving, I lost my 1st BB a bit over a week ago. :( Since I rarely charge to 100%, I may have lost it much earlier and didn't realize it. I charged to 100% on the weekend, and noticed the notched tooth grin on the BB display. Darn, I was hoping to make it through the summer. I know this isn't big news because of everyone's reports, but I have about 18,500 mi on the odometer. This suggests that calendar loss is more important than miles driven (darn, I was hoping otherwise). Unfortunately, this puts a serious dent in my expectation for driving my 2011 Leaf all over town on it's 25th birthday.

I really thought I would be able to forestall the inevitable for another year. I am in PNW, but in SE WA state and we do get temps in excess of 110 F at times. Last summer was tough and much longer heat than normal and with a much higher average temp. With El Nino coming I'm pretty sure we will have some scorchers this decade. Add me to the wiki list.
