Any advice on anything I should do before dropping the vehicle and then after picking it up?
Congratulations to both!
Our 2011 LEAF lost its third capacity bar on Friday, August 25, 2017. Wife was driving, so I do not have a picture from LeafSpy, but I estimate the following numbers:
Our LEAF was manufactured in June 2011. It was put into service as a demo vehicle on September 29, 2011. We purchased it on March 26, 2012 with 2011 miles on the odometer. So it took nearly 5.5 years and 44,000 miles since we purchased it to lose the third capacity bar.
Let's see if the rate of capacity loss is increasing or decreasing:
1st Bar: 4/6/2015 - 24,496 miles - 54.01 Ah
2nd Bar: 6/11/2016 - 33,691 miles - 51.24 Ah
3rd Bar: 8/25/2017 - 46,100 miles - 47.47 Ah
1st-2nd Bar: 431 days/bar - 9,195 miles/bar - 2.77 Ah/bar = 155 days/Ah = 3319 miles/Ah
2nd-3rd Bar: 440 days/bar - 12,409 miles/bar - 3.77 Ah/bar = 116 days/Ah = 3291 miles/Ah
It's interesting that the Ah difference between the second and third bars was 36% greater than the Ah difference between the first and second. Since the car was driven more during the past 14 months than the previous 14 months, the capacity was lost at a faster daily rate. This may also be due to the second period including one-and-a-half summers while the first period included only one summer. OTOH, notice that the miles/Ah is virtually the same for both periods.
As usual, making sense of LEAF data proves to be a challenge! Unfortunately, our LEAF will see even MORE miles over the next 14 months, so those results will again not be exactly comparable.
