Just a quick note here – the LEAF battery did finally go under warranty on Sept 24, 2017, and I got it replaced with minimal hassle back in great shape on October 3. The LeafSPY stats on the new battery actually dropped fairly quickly after I got it which was worrisome, but now (in the very cold weather) it’s holding steady at about 97% state of health, with 62.3Ahr and 90.35Hx.
The stats when it finally dropped the 9th bar were:
Miles: 40623 Ahr: 43.51 Hx: 45.25
I’ve definitely needed that fresh capacity for this harsh winter, it’s been fine, but frigid mornings still show the Guess-o-Meter at as low as 50-60 miles at times.
