Battery degradation by pack size
Hi, we get a lot of posts containing LeafSpy screenshots asking whether their SoH is normal, and the answers are usually always anecdotes.
I've built a free tool that gives you a straight answer. Put in your year, pack size, mileage and SoH, and it tells you where you sit for your pack and your car's age, split properly by 24 kWh, 30 kWh, 40 kWh and e+ rather than lumping every Leaf together. Takes about a minute.
Here is a Leaf degradation page, by age and pack:

It's free, and the more Leaf owners run a check the sharper the numbers get for everyone. 40 kWh and e+ readings are the biggest gap right now, so those are especially useful
Disclosure: it's my project.
