Re: 8 bar battery replacement metrics

Tom,

Did you get any paperwork from your dealership indicating the full 8yr/1000k defect warr / 5yr/60k again ?

Also, did you pay taxes on the $1200 quoted goodwill from Nissan?

Thanks!

Dealer/Nissan EV agree that the battery was ordered back in late June but can not give me any more information on when it will arrive at Dealer.
I can say that currently (Nov., 2016), the replacement battery pack lead time is between 10 and 14 weeks. I just received one that was ordered in the middle of August. This backorder situation is obviously a fluid situation, and will vary according to production schedules of both the battery packs and the new Leaf output, I imagine. I was told 2-10 weeks when I ordered it, and it took about 11.

To summarize my experience I posted about previously, I was denied a warranty replacement of my 8-bar pack because it dropped the ninth bar 3.5 months after the 60-month warranty period. I was, however, offered an 80% discount off a new replacement pack as a "good will" gesture by Nissan. I believe this was because my Leaf was not part of the class action suit and Nissan was afraid I was going to take further legal action regarding the performance of the car compared to their advertising claims regarding degradation made in the past, before we bought it. I wasn't happy about having to pay $1200 for a new battery, but I didn't want to hassle any further and accepted the offer. Now, after having it installed, it is a joy to not have to worry about range and/or charge twice a day to get to where we want to go, so I figure it is money well spent. This will get us through to the 200-mile EVs on the horizon. Here is the Leaf Spy screenshot from driving it home 6 miles from the dealership after the installation, to compare with the image I posted above from when it lost the 9th bar. One consolation is that the new battery has a full 8-yr./100k defect warranty and a new 5-yr./60 month warranty again, since it was purchased and not replaced on warranty, which carries only a 12-month/12k mile warranty to stay at or above 9 bars.

Yes. There was a two-page document I had to sign to buy a replacement battery pack that detailed this. It also contained an agreement to turn in my old battery pack as a part of the purchase.

Also, did you pay taxes on the $1200 quoted goodwill from Nissan?

There was no separate line item for tax on the final invoice, but I have no way of knowing if the total replacement job charge that was the basis for calculating my 20% contained tax or not. The dealer noted a total estimated cost for the job on the original work order, and said they could not offer any additional discount on the work, since it was a "good will" job authorized by Nissan, and then calculated my 20% portion of that total, and told me that was what I would be charged. That amount was exactly what I paid when the job was done. There was no breakdown of the initial estimated cost of $5980 for the complete replacement job shown to me, so it could have contained parts, labor, and tax charges in the total cost, for all I know, but there was no additional calculation of tax on the invoice for $1196 that I ultimately paid.

HTH,

In short: yes. Can't say it happened over a period of weeks, but I dropped from the (now familiar) 66.14 AHr to < 60 AHr over the summer. The question is: what will happen when we exit winter and/or I start driving/charging more (I haven't had a lot of deep cycling lately).

FWIW I'm nearly 8 months and 6,000+ miles in (early May replacement) and I'm at 66.14 ahr, 100% SOH, and HX is even up a bit to 100.63%.

As of today (about 2 months - cool weather and one QC), I'm at 64.21 AH, SOH 100%, Hx 96.5%. Most of the cells at positions 72 to 94 have always been 20-30 mv below all other cells (few exceptions). Cells 1-71 are within 5-10 mv. Wonder if I have a marginal/defective replacement? I'm going to keep good records if I ever need to go for the 10 year "defective" warranty.

I can pretty much guarantee you'll drop the 9th bar at the first sign of summer (location?). You got a good deal!

Marktm,

When was your battery replacement done? And, are you able to obtain the serial number of the battery?

There is a possibility (can't confirm) that you could potentially guess at the battery manufacture date from the serial number.

I think the latest Leaf Spy is able to extract and display the battery serial numbers. Are you able to find out?

Thanks.

It was replaced early Nov. of last year. Apparently there were two labels on the battery case.
Part no. 295B03NF9D, serial number 16A3000196.
Part no. 295B03NA1B, serial number 125N 001804

Not sure which one is the HV battery as the pics were taken by the dealer when it was replaced.

I know LeafSpy extracts the VIN - have not seen any numbers that are similar to the ones above.

Let me know if you have more information.
2012 Leaf SL; 34,000 miles. 12 bars - Battery replaced November 1st, 2016.
