The oldest mass produced electric car is the leaf and some of those batteries have lost a lot of capacity but they were never thermally managed or charge limited like every other model out there now. There's Tesla's that are over 500,000 miles and still have the original battery. Toyota Prius Hybrids have a battery and they never need replacing.
It's a non issue

I dunno, I think most peoples' personal experiences with rechargeable battery powered devices would suggest otherwise. I have three new(ish) devices within arms reach that I had to replace primarily because of battery issues with their predecessors. I can tolerate a lot of performance issues with aging products, but the battery seems to be a common existential issue.
There are probably lots of reasons EV batteries could be immune to those issues, but IMO it's reasonable to have some concern.
My main point is that I wish all of the eggs weren't going into a single half-ton basket. I'm sure there are lots of efficiencies achieved by building such big batteries, but I'd be far more interested in the opportunity to right-size the battery(s) to your needs.
i.e. instead of a single 500kg battery, could a vehicle take up to four 125kg batteries instead? I'd probably opt for 2/4 to start and consider adding/replacing them down the road if necessary. Almost like RAM or HDDs on a computer...
