In 2022, the answer is: Maybe.
I took in two Mid 2015 MacBook Pros for new batteries in October 2022. This was through an Apple store in Bethesda MD. The machines were sent by Apple to Houston Texas for service. Both were initially given a $199 estimate but then this was brought up to $322 per machine for each of the two machines. On one machine, they replaced the speakers as well (the machine that received a new top case), the other machine received a "new IO board". The small print says that these may be remanufactured parts. Apple's own billing said that the top cases on both machines were replaced but the repair shop invoice from Houston, which was included in the repair return bags, matches my observation that on one of the two machines they were able to replace the battery without replacing the slightly scratched top case. They still charge the $199+ whether or not they also replace the top case. On both machines, the speakers and IO boards seemed to be working fine before the repair. I wonder what other's experiences are with cost when trying to get proper Apple batteries in 2022 on older machines.
