I think all of the batteries probably come from the same vendor in China. iFixit totally punted on any refund without getting their bad battery back (3+ hours). The problem is if you bring a batteryless MacBook to Apple, they won’t accept it. Shame on iFixit. They know they sent out bad batteries for an extremely difficult repair. Disappointed.

This code change DOES NOT work.

WAIT!.. STOP.

iFixit has had a slew of defective batteries that they will require you take out and return (after gluing them in). Search on: "Battery percentage suddenly drops" here on this site. This process is 50 steps to get the new battery in, and another 50 to put all the parts back. For $199, Apple will do the whole repair, warranty it, and also replace the trackpad and the keyboard (because it's easier for THEM to do).

Ifixit WILL NOT stand behind defective batteries unless you spend another 4-6 hours swapping in a new one. NOT. WORTH. IT. See posts here (Battery percentage suddenly drops from ~60% to 7%) on frustrated customer’s multiple attempts and class-action lawsuits.

Re: Mid-2014 15” MBP…

Soak a paper towel with adhesive remover, and lay it over the residual adhesive in the METAL parts of the cse, and you can remove much more easily (try razor blade). On plastic trackpad base, use plastic tool.

Also, the torx screw in the center of the trackpad base is your click adjustment. You may want to calibrate that BEFORE putting in the new battery.

Success!

Recommend: MAGNIFYING Glass. DO zoom in on the photos in this article to understand exactly how each connector disengages.

On MID-2014 Retina, they definitely lift up and out.

Yes. LIFT up slightly on one end to clear retaining pin before tugging.

A MAGNIFYING GLASS really helps on this. The cable’s sheathing may need to be pushed back a tad to find a place to get leverace to work the pin out.

I found placing the spunger under the part of the connectors AWAY FROM THE WIRE (top and/or side depending on which of the three you’re finessing), and then rocking them gently from side to side pops them out gently.
