MUCH appreciation to the author of this guide, and to those who have posted very helpful comments along the way. The instructions - and especially the photos - are outstanding. This repair is definitely not “easy,” but it is certainly do-able. It’s important to follow the instructions very carefully, without jumping around, to assure no damage to delicate connectors. This repair should breathe new life into one of the very best laptop models ever made by Apple. My old battery lasted six years. If the replacement lasts half as long, I’ll be happy.
My replacement battery came with a clear plastic protective cover stuck across the top. This protective cover helps keep the four battery cells and their frame aligned properly for fitting into the space. Remove the protective cover (it peels off easily), however, before closing up your computer.
I agree that test-mounting the new battery, including re-attaching both speakers, BEFORE removing the adhesive covers, is essential for perfect alignment of the batteries… and especially important for alignment of the battery connector and its solo screw.
I used GooGone adhesive remover (non-flammable, non-toxic) to loosen remaining adhesive. It worked well, applied with a paper towel. It took several applications to thoroughly clean the computer case. Allow it to dry thoroughly before adhering the replacement battery.
My successful alternative to the plastic cards was to use a plastic putty knife, an inexpensive purchase from any pint or hardware store. This tool gave me a strong, grippable handle with which to carefully “work” the plastic blade under the battery cells.
Before proceeding with the solvent, I suggest considering using dental floss to slice through the old adhesive. (See next step 22 below for more details.) Because the solvent is so dangerous (flammable and caustic), I felt the “dry” use of floss would be better. I assumed that I could revert to the solvent if necessary after trying the floss.
My model (late 2013 MacBook Pro Retina), did not have any screws in these locations. They were rubber “feet” in the same locations. They are not attached in any way to the computer. They simply lift up with the plastic battery frame. My replacement batter kit came with the plastic frame - and these rubber “feet” - already installed. No need to save the old ones.
Same note as above: Important to keep track here of which screw is which, for reassembly. The longest screw belongs in the middle socket. The shortest goes in the socket at the bottom of the picture.
I, too, found it unnecessary to unplug this speaker. It was easy, and not stressful to the speaker cable, to fold the speaker upwards and rest it on the motherboard.

The key to accomplishing this step easily and without danger to the socket… is to follow the instruction (and the picture) PRECISELY by placing the spudger flat end under the CABLE (not the connector). Lifting the CABLE easily removes the connector from the socket without getting anywhere near the socket.
