Right now, looking at buying a used EV, I am more scared that the battery or electrics fail for some reason than I am of their gradual degradation over time.

I don't know how likely that is, but it's putting me off anything other than manufacturer approved used with a solid warranty.

Get an ODB2 reader and check the battery condition before you buy.

Thanks, I'll look into that

I should mention the Dr. Prius app, which is not limited to the Prius. The Dr. Prius website lists ODB2 readers that are able to access the battery data. Some single-board ODB2 readers can't.
