Lost the 4th capacity bar yesterday.

Miles: 54,410
Years: 4 ~
AHr: 42.22
SOH: 64%
Hx: 43.15%
kWh remaining: 13.5 ~
GIDs: 171
Miles --> 1 kWh: 50

Total QCs were 10. Two of them were on one day prior to 4th bar loss. Austin has just two QC locations.
Almost every bar was lost after a top up.

1 turtle (in the first week).

LeafSpy Pro and EVSE upgrade have been life savers. Nissan should buy both of them out.

Maintenance was $800 ($200 /yr). That includes new tires and a 12v battery.

Insurance was $800 /yr (on a 3-car policy. Total for 3 cars is $1,520 /yr).

The car has been great except for the battery degradation. It is my zen car in crazy Austin traffic. Easy to park and weasel around. It also gives me cheap thrills from racing the $100k cars at the stop lights. The most expensive car i have owned ($31k back in 2011 after the tax break). Although my first new car (now long gone, 1993 Acura Integra, $13k) still gives me the goosebumps. Planning on keeping it for the long term as my boys are just about to start driving.

Congrats on qualifying for a warranty battery! Out of curiosity, do you plan to ride out the summer with the old battery to spare the new one the wear?

Lost my first bar yesterday (8/30). 25420 miles. SOH 84% (55.65AHr), Hx = 70.51%. Down from 56.04AHr (85% SOH) on 8/11, 56.42AHr (86% SOH) on 7/10. The first reading I took was back at the beginning of April, where I was at 56.91AHr/86% SOH at ~20600 miles.
I haven't been babying the battery, but I haven't been abusing it, either. Degradation definitely accelerated in the past 2 months with the warmer weather. Hoping to stay at around 82-83% SOH until next May or June, anyway...

I just bought a 2012 SL with 38,900 miles tonight. I was looking for a 9 bar and found one. It was $9,400. I ran LEAF pro and the AHr is 42.94 with SOC 65% and hx 58.77. It has an open record for some sort of update so I'm going to drop it off at the Nissan dealership tomorrow morning. I hope the 9th bar drops soon.
