Yay! I'm surprised you didn't wait a bit longer - perhaps to be the first documented 6 bar loser?

Anyway, I'm looking forward to seeing how your replacement pack holds up in the Phoenix heat. :)

I could have sooner but chose to wait as long as possible to maximize my ROI on the first battery and ensure I get the latest chemistry. I had to leave town hours after taking possession so no 100% charge numbers yet, but at the dealer I read 270 gids on a 89.8% SOC. Assuming full charge gets me to 96% that should be 288 or so gids! Oddly, the pack voltage was 393.9V which prior to the swap was what I saw on a full charge so maybe the SOC reading was off. Once I get back I'll find out. Maybe I will finally get my 281! Other details from the sample are: 99.8 HX; 100% SOH; 66.14 AH.

P.S. The dealership I took it too (Earnhardt Nissan off Superstition Springs in the Phx area) was awesome and took great care of both me and the car. Highly recommend them for anyone else planning service in that area.
Based on 270 Gids and 393.9 volts at about 90% SOC, it is clear that you received the new battery chemistry. Those numbers look like what I am seeing with my 2015. A full charge for my 2015 yields about 292 Gids (saw 293 once or twice) and 395.5 volts. I have also had good service over the years from the Earnhardt chain, but their Nissan dealership is too far from my house.

Enjoy the increased (restored) range!

I got my 281! :D
Back in town and my first full charge (after sitting at 50% charge for a week) brought me to 284 gids at 94% SOC and 394.5V. I also got a read on the ESR on my drive to work this morning. My old battery was hovering around 160mO at 54% SOH & 33.5 Hx (it was 90mO at 71% SOH & 50.3 Hx when I first started tracking ESR). The new one read 78mO this morning at 100% SOH & 99.6 Hx.
