Thanks for finding that: I'm getting close! Looks like we took delivery at about the same time, but he's got > 10k miles on me. Looks like the heat here (in TX) is going to hold out for at least another week.

My car has been in the service dept. since 8:00 am and now they say I won't get it til 5:00 pm Monday. Does it take two full days to swap the traction battery?

Who was it where their car was gone for weeks? That always seemed massively excessive, but it can happen.

The book calls for about 3 hours to swap a pack, IIRC, plus time to charge to 100% and to verify that all is well otherwise. I have a feeling they just didn't want to work on it today, or maybe their (one and only) LEAF specialist didn't show up for work.

Most of the delays I've read about have been computer related. Car won't talk to new battery, etc. When I took my Leaf in last January for battery usage report and P3227, it took two or three attempts before the firmware upgrade was successful. Walking by the service bay, I'd hear "I've tried everything and it just isn't working..."

Mine was collectively out of service for about a month. I meant it took three days after they received the battery and started work to the time it was ready

I'm at 42.21 AHr, with 9 bars still remaining.

We are now almost to October so my hot days are running out. Any advice on how to push it over the edge?

I always charge to 100% and park in the sun whenever possible. I just went to my first quick charger this morning, but it didn't appear to have any noticeable effect (42.22 to 42.21 after it was done). I'm to the point of not being able to make it to work in the winter without a new battery so I'm very hopeful the bar will drop sometime.

Wow you're pretty far down there - I'm at 43.2 and expecting (hoping?) the bar to drop any day now. Nobody knows exactly what causes the bar to drop, but the best guesses seem to be that after passing the threshold some amount of time or charge cycles or miles or something must pass before the bar drops. Would you happen to know when you crossed 44 Ah?

If that theory is true, then there's really nothing you can do to hasten the bar loss - it's probably just a matter of time. Clearly your battery has degraded enough - others have lost the bar at up to about 43.5 Ah. I'd just continue to use the car as much as possible, and make sure you post the results when the bar does drop! Can you provide more details in the meantime (location, miles, manufacture date from door jamb, and purchase date?)

My experience buying a replacement traction battery for a 2011SL follows. Replacing now since I would soon not be able to make a one way commute of 60 miles, down hill (1400' loss), driving 50 mph on the freeway, without charging enroute.

Called 4 Nissan dealerships in the LA area:
1) One did not return my call;
2) Two took relevant information. Said they would call back after checking. Both called back, one quoting $10k, the other $5500 (Glendale Nissan).
3) One wanted to see the car to verify the proper battery number before giving a quote.

After determining from this forum and corporate reps that the 30kWh battery would not be compatible, I ordered a battery from Glendale Nissan. The Service Rep verified my car information, wanted to keep the car and give me a loaner. Told him I preferred to keep driving it until they get the battery. The next day, I was asked to sign this "Disclosure Form & Trade-In Agreement."

The Agreement could be worded more clearly in Section II., regarding the Warranty of a replacement battery for the replacement battery...if you get my drift

Battery and adapter kit were at the Dealer eight days after signing the form. They said the adapter assembly took longer to arrive than the battery.

Dropped my car off in the evening. Three business days in the shop. Gave me a loaner. Picked my car up on the fourth day. Said that getting the new bottom cover delayed things as well. Total cost was $5640 (including tax).

Original HV Battery @ 104.2k miles:
Last 100% Charge- 155Gids (~11.5kWh to Turtle)
AHr 36.13
Hx 33.72
SOH 55

New HV Battery:
AHr 66.14
Hx 99.99
SOH 100

BTW: I won't be commenting or replying whether it makes sense to replace the battery or not. Other relevant information is in my signature below. The car has a Brusa charger, so up to 7kW L2 charging is available.

Wow, you used up that battery! At 36 Ahr, how many capacity bars did it indicate? Not hard to choose dealers, with one quote at $10K and one at half that...
