Set a threshold by the following:BuckMkII said:SageBrush said:2- 3 kWh are reserved by Nissan. A new battery at 100% would be about 21 kWhBuckMkII said:The 2014 full capacity is 24 kWH, right?
Thanks!
Still not sure what to set as my thresholds to pass on the car. Does SOH > 91 or capacity > 19.3 kWh seem reasonable or unrealistically stringent? The car in this post has a similar history (but is a 2015) and a much lower SOH (87%, probably due to QC usage?) I was a little surprised by that number.

This is the car I'm looking at, btw.

Whereabouts in Colorado do you live? I grew up in Littleton and lived in Boulder for eight years for college and my first job. Still a couple more years until I've lived half my life a mile below normal ground level!
1. Needed range; figure out kwh by estimated kWh/mile. I used 4 miles/kWh. Weather can reduce battery range a lot, so be conservative here.
2. Anticipated loss over time in years
3. Useful range in years required
4. Cost
5. Fudge factor
As an example,
Our longest drives are ~ 60 flat miles (actually 45 miles with a climb)
I wanted the car to last at least 3 yrs, and figured up to 5% loss of range per year
1. 15 kWh
2. 15%
3. 15/0.85 = 17.6 kWh absolute minimum from the time I purchase. I shopped for at least 19 kWh but if a dirt cheap LEAF had fallen in my lap with 18 kWh I may have been tempted.
4. I paid $7,000 net, so I figured worse case is $200 a month -- but probably much better.
I had a lot of leeway and room for error because we have a second car with unlimited range that can always be used in a pinch (like in a snow-storm.) LEAF as a single car requires other considerations like public transport, rental, or L2/L3 availability away from home if the LEAF is not up to the trip.

To be clear -- the calc to figure out usable kWh from a test drive is far from a perfect test; it is meant to give you confidence that the LeafSpy readings have not been tampered with by a reset from a shady dealer. If in doubt -- extend your test drive. The longer the drive, the more accurate the calc.
