Chosen Solution

I need to replace my MacBook Pro battery. The battery is so swollen that the trackpad won’t click. So I can’t pull up the Apple menu and the “about my Mac" screen. I’ve replaced it before, so I searched ifixit for the part #: F163-019-1. I got no results. How can I buy the correct part?
