That’s the most extreme repair run I’ve seen. Like some others have said, there could be something that’s damaging them. I know exactly what damaged my battery so that now it recommends battery service: Overheating using An external monitor and chrome tabs. The thermal management at higher cpu of this 3 year old MacBook Pro is bad but browsers are needlessly resource intensive. After about six months of ignoring how hot it was getting the battery notice started. A while later it would shut off at around 40% battery. But I still put off replacing the battery and magically after an OS update it no longer shuts off at 40%, and goes all the way down as it should. I assume the update included some throttling if the battery isn’t providing adequate current. tldr: My Mac has battery issues and I know the exact cause. There string of defects you’ve had seem statistically unlikely as pure random ones while not impossible. There may be something causing them.
