It seems a bit amazing that these Battery Packs in WA
appear to be "aging" so little, but perhaps the lack of exposure
to any significant amount of hot weather is the key.
Or perhaps the gid count is just as inaccurate as a measure of Wh in cooler climates, as it has been shown to be in hot climates?
camasleaf
My old Leaf is still at 281 after 28000 miles. It dropped to 278 in mid Feb but the readings came back up at 281 mid March.
I am so curios if the old one will go as far as the new one. I am waiting for the weather to improve where no heater or defog is needed, then put the back tires from the new Leaf to the front of the old Leaf and run both to turtle in parallel driving.
I have not done any maintenance on a car for over one year and my tools are getting rusty. Swapping the tires will be a good exercise, but I need to by a jack.
A lot of us are curious. Just as an aside, is there any way you could have the ~75k mile PNW LEAF also participate?
That is the comparative range test result I'd really like to see!
Please be sure to have battery pack temperatures of all your you test LEAFs equalized, especially while charging, and that CarWings is operational on all cars, before you make this test.
Without the regen kWh reports from CarWings, it is impossible, IMO, to measure variations in driver efficiency between LEAFs.
If you can control these, and all the other test variables well, your range test results should be extremely informative.
I personally am skeptical of the gid-indicated near-immortality of cool-climate LEAF battery packs, so my best guess (and it's only a guess) is that your "new" LEAF might display about 5% greater current available battery capacity than your old one does.
That ~5%, (+ or - ~2%) is the capacity loss I believe my LEAF probably has experienced over a similar period of time.
My loss was measured over a much lower differential of miles (~13,000, as opposed to your ~23,000) but my LEAF also probably has experienced considerably greater exposure to high battery pack temperatures.
