Mostly it's money for the consumer. I have a Prius so it might be a little different. But when the hybrid battery goes out costs something like $7,000 to have it replaced. A mechanic in town will repair it for $1000.
Now my car isn't worth $7000 so if I had to replace the battery then I would just get a new car and this one might end up in the scrap heap. In getting it repaired I have gotten something like 6 more years out of it, at least, and that's a pretty significant environmental savings.
And that's essentially what the article is saying.
I saw something like this in covington, Kentucky just south of Cincinnati. Apparently there is a small movement https://www.freeblockbuster.org/
