You don't say when your warranty expires but if you have the calendar time if I were you I would stop driving the car now leaving it plugged in, with the climate control timer set to go off everyday. THis will do four things. First it'll keep the 12 volt battery charged, then it'll keep the traction battery at a relatively high SOC, and it'll cause the battery to cycle a bit as the climate control while plugged in does this pattern of discharging the battery and then charging it back up, and it will keep the inside nice and dry. Then figure out how many miles you can drive it per week such that the calendar warranty expiration and the mileage expiration line up. This will allow you to continue to monitor the progression of the battery capacity degradation.

I will stop driving immediately. I am not sure when my warranty is up. My service report shows del date of 12 oct 12. In regard to running the ac, would this show up on the warranty report, I would hate to not get it. Would it be better to drain it via ac the QC I only live 5 miles away from one and only have a total of 40 QC.

Yeah, I believe the service paperwork the dealer provides you is reading the delivery date from Nissan associated with your VIN and thus would be your warranty expiration date. So with a whole year left you've got lots of time to let the battery age it self.

The Nissan preferred way to drain the traction battery as per the service manual (used for testing and such) is temp at 90, defrost mode selected and windows rolled down.

What do you mean by total of 40?

I noticed my post was not clear and edited it but this is what I ment.

I will be able to not drive my car until JAN if I choose.

If you like driving I think taking it out for spirited drives, QCing, more spririted driving, repeat, etc. will cause the LEAFs poorly engineered battery to get nice and toasty which I think will definitely help age the battery. Just make sure your consumption of miles trends such that you will not run out of miles before you run out of calendar time.

I don't think we know exactly what data Nissan is able to keep track.

QC actually improved my battery by 1%, best is to charge at 100% every day.

Finally, 4th bar dropped at 33,842 miles 3 years and 10.5 months. 43.34 AHr

Scary call with Nissan when they told me the put in service date was 10/05/2011, when I bought the car 11/29/2012. Fought and fought until they confirmed it. Then they said my vin had a red mark for the lawsuit, but I opted in this year when they settled and I got the No Charge to Charge card from Nissan. Nissan says 10-12 weeks wait once approved. Dropping car off tomorrow at Regal Nissan to verify it and they are giving me up to 3 day free rental to allow them to do all checks. Paid off to charge to 100% every day!

I think any jumps from QC is short lived and not a permanent increase and thus continued QCing to high temperatures is definitely not going to be good for the long term capacity of the battery. I think even more frequent level 2 charging maybe cause a bump in reported battery capacity. One possible explanation is that this allows the battery to be better balanced.

I am getting mixed results on what ahr that the bar drops right now I am at 44.2 last night 44.27 then the night before that 44.2

Think the formula is x/66.25 = 65.499 thus x = 43.39 Ahr

Hello -
I don't know if this has been covered elsewhere, but does anyone know how to get a full battery report out of the OBDII Scan (LeafSpy), or is this not possible? Is there any information the dealership tech gets that we don't get on LeafSpy?
I am grumpy about having to pay the dealership for the privilege of getting told how much my battery has degraded since 2011 (down to 74% capacity, according to LeafSpy). In my opinion Nissan should be thankful to get the data on these first-gen batteries, and a yearly battery report should be free as it was for the first two years.

Thanks,
Josh

Hi all i posted here before about my battery hitting 8 bars and me getting a new battery from the dealer under warranty.

Today i am unhappy to report that this brand new replacement batter after only 3 months of driving and no quick charges dropped 1%. it is upsetting to see Nissan sliding downhill on these cars
currently LeafSpy reflects the following values:

Ahr 63.70 SOH 99% Hx 95.86%

Hx dropped 10% in 3 months.
Ahr dropped 4% in 3 months
at this rate ill be losing SOH at 4% per year.

I could not be more dissapointed
