I found this to be more difficult than the edge sections. I had to reapply a few times the adhesive removal from both sides of the center sections before I was able to pry the battery. Take time and use the adhesive removal several times.
Apple Canada quoted me ~300$ for battery + keyboard replacement though acknowledged that the battery had died prematurely (1.5 years since the date of purchase). When I opened the case two out of six sections were swollen. I ordered from ifixit their battery and the tools and with rate conversion + delivery to the border + taxes at the border it came to 180$. After ~2 hours I have 100% healthy battery installed in my macbook pro and it saved me 120$.
