A few years ago, I got a really good deal on a Mid 2012 MacBook Pro Retina 15-inch because someone spilled Sprite on it. The logic board was completely dead so I took out the logic board and sent it to an independent shop for component level repair. The computer works great so I gave it to my sister. The computer has worked fine since then. Anyway, it has been a few years and the computer is telling her to replace the battery. She sent it to Apple, but Apple wants to charge her $1250.
