    You should go by warranty remaining on battery. Either one of those could develop a dead cell tomorrow, or they could last 20 more years with no worries. Battery aging is unpredictable on the level of an individual battery pack, you can only predict averages of large fleets. When I used to refurb Macs, I saw failed (swollen or low capacity and about to start swelling soon) batteries with <100 charge cycles and completely fine batteries with 2500 charge count and of course everything in between. 1000 was the expected lifetime per Apple.

        EV battery warranty is usually 8 years, most EVs get dumped way before that because nobody wants to take the risk of owning a very expensive paperweight if the battery fails after the warranty is over. Though there are stories of scumbag manufacturers saying the warranty won’t cover more than the value of the car, so you might not even get a new battery fully covered by the battery warranty, as the battery can be more expensive than the car.

        Reputable dealers will also sell used cars with their own warranties and then there’s CPO cars from the main dealers.
