Re: 2013-2014 bar losers and capacity losses

Mon Oct 08, 2018 8:43 am

Looking back at my LeafSpy log, I see that in the summer of 2017 the difference between my SOH and Hx was consistently 2% to 3%, last winter it was reliably at 4%, and over the last few weeks it has been steady at 5% to occasionally 6%. Is this typical? Is the increasing difference diagnostic of anything, or do you think it's just a feature of the algorithm?

My latest readings are:
ODO 50999
AHr 54.5
SOH 83.3% (lowest fluctuation ever was 82.8% a couple of weeks ago)
Hx 77.8%

Lost bar 12 over a year ago. I guess I have another year before I need to worry about bar 11 dropping?

bar 12 lost 8/21/17
on 8/23/18: AHr = 54.6; SOH = 83.5%; Hx = 78.2; ODO = 49,746

https://www.facebook.com/groups/nissan. ... 210418941/ has a pointer to a 7 bar '13 Leaf at 60.5K miles. Unknown build month. Guy apparently wasn't aware it was down to this point until now.

I wonder if he hit 8 bars before his capacity warranty expired but his wife didn't let him know.

'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)
'06 Prius

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

For a new post-April 2013 car, when freshly delivered to the dealer, what was the Ahr capacity shown by LeafSpy? I see "63 Ahr" on the first page of this thread. Is that the consensus?

Sorry I can't remember where to look up this fact.

It depends, sounds like your car survived this summer just fine, so I think you won't have to worry about dropping another bar until next summer. My case is different though, I was at 54 AHr back in March of this year and by August I lost the 11th bar with 49 AHr. Car is garaged but parked outside at work, so as long as you keep the car cool you should be fine.
2013 LEAF SL w/Premium Pkg, Brilliant Silver, 53,144 miles, LeafSpy: 49.756 AHr, SOH 74%, Hx70.30% as of 08/20/2018, 10 bars, 28 QC, 2069 L2/L2
