Not easy, but totally doable for an intermediate tech DIYer.

Meu Problema

My MacBook Pro 13" Retina Display battery had undergone 710 cycles and OS stated that it was time to replace.

Minha Solução

Went pretty well, a lot of parts need to be removed. Found it incredible that there were so many types of screws. Must have a telecom toolkit for this one.

Meu Conselho

It's very important to keep organized during this replacement for ease of reassembly as there may be different size/length screws in the same step.

Someone else had mentioned using isopropyl alcohol to remove the adhesive from the batteries which is truly a great idea.

In my specific case, isopropyl alcohol was not something I had on hand. As a substitute, I used my wife's nail polish remover since acetone evaporates fairly well (yay high school science class FTW) and sure enough, they came loose no problem. This method is NOT guaranteed, but to the careful DIYer can work great in a pinch.
