I called the parts department today for a mundane question (re: floor mats) and got the parts manager, he figured out that it was my LEAF in for battery replacement and got all excited and geeked out on the parts, the LEAF, the process, "yeah we replaced a couple cells before but never a whole battery! Yeah, I took one of the old cells apart because I was curious, it was like filled with gel and stuff ..."
Anyway, he said they got the bill for the new battery, which means it must have shipped, and that there were 16 (!) in stock in the Chicago area warehouse. So yeah, I think I'm getting a new battery (despite service advisor's pedantic warnings); the guy spit out the part number, and I didn't catch it all but i think he said 295B0-9RB9D, close to what mxp reported
, and hopefully will get it back next week.
