When they’ve reached end of life for the car, they are still useful.

EVs require high energy density so they get replaced when they don’t store enough energy for their weight. However for grid storage, weight doesn’t really matter (at least not as much) so a battery with 80% of its original capacity is a good (and cheap) solution.

When the market is mature, it will good for car owners who need to replace their batteries because the old one still has value.

I imagine this is how Apple would justify it - if there are internal screws or shields missing then it’s a sign that it has been repaired previously by a 3rd party. It might work fine, but it’s not to the original Apple specification.

The Apple store don’t want to take responsibility for those repairs so refuse to do further work in case it leaves them with liability.
