But your right it’s not comprehensive. https://arstechnica.com/cars/2019/07/nissans-bigger-battery-...
I don't really know how Leafs batteries are connected but one could also expect that a smaller battery pack has less redundancy. If due to bad luck a couple of cells go bad you lose a lot of capacity. More likely to happen the less redundancy you have.
So 60 mega-metres? 60 Mm? :)
Edit: Downvotes? Really? Lighten-up people. Sheesh. (And it is technically correct. :)
I don't really think it's as much temperature management or some defect.
I think it's the size of the battery - it's small. You can figure out the lifetime with simple math. A tesla with 250 miles range with 1000 cyles would have gone 250,000 miles. A leaf with 75 miles range * 1000 cycles will have gone 75k miles.
And telsa recommends keeping the battery between 20 and 80% and I believe the slider says "daily" is 60% and "trip" is 90% (for occasional use)
A 2012 leaf will default to 100%. There is a way to change this to a lower value, but it's well hidden in the system settings and I believe you have to agree to telemetry to set it.
And if you DO set it on the leaf, you will limit your range to about 45 miles (of ideal driving)
Anyway, the idea is that newer cars have bigger batteries, a much higher lifetime mileage, and no need to cycle the battery charge so high, so low, or as frequently.
(a tesla driven 200 miles a week might cycle the battery once while a leaf would cycle every day)
A battery isn't like a tank of gas; it's never truly off. It's full of reactive chemicals and powerful solvents, and it degrades over time even if you don't cycle it. How long did it take your battery to drop?
For reference I live in southern Florida so we have hotter than average climate.
