Some more examples from a UK EV forum.
Renault Zoe, 177000 miles and 77% battery health.
Another Renault Zoe at 48000 miles and 98% health (yes I know 46000 miles isn't much, but 98% health is actually as good as new)
Leaf at 177000 miles and 77% health.
It's interesting one of the links you attached got their Leaf battery loss figures from the USA.
There are examples of early Leafs in 'hot states' suffering accelerated battery degradation if the cars are left parked in blazing sun all the time.
As far as I know, later models addressed this.
That hardly applies to the UK, they get stuff like dashboards cracking from the sun.....
