You sound more optimistic than I would be that the car will have 12 bars after another hot summer.danrjones said:I'll be blunt, I'm glad I'm getting rid of it later this year. I don't really want to try and sell it with a bar missing.

20 - 80% routine is also probably fine, but you are certainly right to only DCFC when needed. I take this battery nanny-ing one step further and only charge soon after a drive in the winter (before the battery gets cold) and in the AM in the summer so that the car battery does not sit at a high SoC for long and has had a chance to cool down overnight. Oh, and the car is parked in the shade at home and rarely sits on hot asphalt for any length of time when being used.DougWantsALeaf said:My charging regimen is now DC charging only on a trip when needed (sad for my NCTC), keep battery between 30% and 70% unless driving far.

Our 8 year old LEAF has an 83 SOH and loss of 1.25 Ahr/year the past two years, so I'd like to think we are doing well by her and the degradation rate will not increase.
I had the same thoughtdanrjones said:Now there is some good news: The warranty is still has 6 years left, so Nissan may be giving someone a new battery later.
One bar down.DaveinOlyWA said:Rate will probably increase as the capacity drops but sounds like its holding up well. Have you lost a bar yet?
SageBrush said:One bar down.DaveinOlyWA said:Rate will probably increase as the capacity drops but sounds like its holding up well. Have you lost a bar yet?
I was actually thinking that the rate should decrease as capacity is lost, and IIRC Nissan expected the same. What actually happens is probably pretty variable since there are multiple degradation pathways. My capacity loss graph appears to follow the 'less as time goes on' expectation but I'm not willing to call it yet with confidence because of confounding factors that include living in 3 different climates, a probable battery reset before I bought the car at age 3 years, and markedly reduced use during Covid.
Yeah, and I'd llke to take some credit but I honestly think Nissan batteries have lousy QC so for all I know I was lucky and got a good pack.DougWantsALeaf said:That's great for a 2013 Leaf.

I obviously *think* I know ways to prolong battery life or I wouldn't be doing them, but Doug is right: anecdotes just do not mean much. In part because conditions vary from car to car and from climate to climate; in part for the reasons you mention; and in part I suspect because of wide variation in battery quality from the factory.DaveinOlyWA said:SageBrush said:Yeah, and I'd llke to take some credit but I honestly think Nissan batteries have lousy QC so for all I know I was lucky and got a good pack.DougWantsALeaf said:That's great for a 2013 Leaf.
Not buying that. I have found that most EVers don't tell all when explaining their charging habits. You are simply more aware of what needed to be done and found ways to do it easily. Later versions w/o custom charge settings just encouraged people to think "Nissan took care of it" so I don't have to w/o realizing Nissan was the ONLY manufacturer w/o custom charge settings. They deluded themselves into thinking it didn't matter.
You really wouldn't believe what people do under the impression they are being a "good EVer" and then recommending it to new EVers.

Yes I know but no choice. I don't want to pay back the CA rebate, so technically I must keep the vehicle for a total of 2.5 years.
not sure they really check but I don't feel like taking the chance. And the end of the year usually has good deals anyway.
but man the SOH keeps dropping....
This AM down to 87.82% with still less than 9200 miles.
I'd post a graph but images here require being hosted elsewhere, correct?

The Model 3/Y is known to develop calibration errors with certain home charging routines, so unless you have good reason to think that the LEAF correction is also a calibration error, your attempt to imply that Tesla EVs also suffer LEAF level battery degradation is wrong.DougWantsALeaf said:On the same breath, this 2020 M3 owner who posted today is down 12% with not many more miles, so who knows what's expected. (Not meant to be a trolling comment, just that many evs show a range of loss in first couple years).
DougWantsALeaf said:Wow, that is a big drop given your limited miles. When is the last time you charged to 100%?

DougWantsALeaf said:Ok, so you have been babying the battery. Not sure then what might be driving the loss (real or bms). The fellow in Japan with a 40 just hit 100K miles with lots of DC charges and just over 3 years with SoH of 84% (still 12 bars). This bms is still a bit of a mystery as usage cycle doesn't seem to explain the outcomes.
Sage, yes many (but not all),see some artifical loss due to calibration.
You are grossly uninformed. When a change in charging routine improves the reported range, it is called a calibration issue. Instances where an increase in reported range are not reported are of uncertain cause, of which battery degradation is one possible explanation. The ONLY confident way to document battery degradation is by showing a reduction in energy required to charge from a low SoC to a high SoC under similar battery conditions.DougWantsALeaf said:Sage, yes many (but not all),see some artifical loss due to calibration.
