Remove the plastic cover adhered to the battery contact board.
This plastic cover wasn’t included with the new battery so I placed the original one back in. Was it supposed to go back in? This detail wasn’t clear since the original cover didn’t fit exactly over the newer battery connector. Plus any stickiness of adhesive that may have been there was gone.
Hi, any issues with you computer after a year? I didn’t put mine back in either…
Kevin, I forgot to place mine back in! How is your laptop doing without it?
Is it ok if I did put the plastic cover back in?
yes, it is okay

Remove the following screws securing the battery connector board to the logic board:
-
Two 2.8 mm T6 Torx screws
-
One 7.0 mm T6 Torx shouldered screw
Top screw in this image was not a T6. I found that a T5 bit fit this one.
I can not put back top screw holding the plastic part. Help please
The colors of the circles marking the locations of the screws in the photo are reversed.

Use tweezers to remove the small plastic cover located near the bottom right of the battery connector board.
-
-
-
Remove the wide head 6.4 mm T6 Torx screw securing the battery connector to the logic board assembly.
I lost this screw! How important is it? Will it be okay with just the 3 previously removed screws?
-
-
-
Carefully lift the battery connector board up off the logic board.
-
It is recommended to bend the battery cables just slightly, to keep the board suspended up above the logic board and out of the way.

Grasp the Interposer with tweezers.
-
Lift the Interposer off the logic board and remove it.
WHy to remove battery contact board? Replace can happen without it also, right.
You don’t want to work on a live system as you could damage parts

you must lift it absolutely vertically, or it fouls against the locator pin in the corner- you can easily get the impression that it won’t come over the end of this pin- almost like it’s rivetted in. it isn’t. get a good grip on it with the tweezers in the centre hole & one of the sides, & lift it STRAIGHT up.
What happens if the Battery Contact Board fails?
Be extra careful when tightening down on the interposer. When I powered on upon completion, the battery was not connected. When I opened it back up, I saw that one of the little metal nubs holding the interposer in place had snapped off (the one on the side, not the corner). I was able to carefully tighten the wide head screw back in, watching the alignment, and the battery was successfully recognized. Hopefully the connection holds up.
So something similar happened to me. One the the metal alignment nubs snapped off, and when I went to screw down the interposer it started emitting a burning smell. Do you guys think I fried the board? There doesn’t look to be any visual damage but the computer wont turn on.

Where can I buy a replacement interposer? I may have lost mine in the process of replacing the battery.
земля пухом братан, ты приехал
I really dont understand why to unplug so many parts if the SSD can be easily removed without all this effort. its not even connected to the battery..
I was reassembling and put the interposer back and when the battery contact board touched the interposer, there was a little spark. Should I be worried?
I skipped this step but still OK.
Warning to all: I snapped off the alignment nub as well, as I removed the interposer, and now it won’t start with a brand new battery. Any solutions to a “snapped nub” issue?

Could you tell me where is the sensor of temperature? I think than my fans are going fast because of the sensor. Thanks
If don’t have one of those neat project mats, then you can use small pieces of flattened blu-tack to hold the screws. If you arrange them in the shape of your mac book cover, and put the screws down methodically, you can get a one-to-one mapping of the screws to the correct screw holes.

Or you can use an ice tray where you put the screws and the parts in separate bays in the same order as they come in the instructions.

On my model A1425 these were all 1.2mm P5 screws. They all looked the same to me.

This is great! I used a small magnetic white board, and wrote on it to identify the parts as I went. This whole process, from the fast shipment to the great instructions to the complete, high quality, tool kit has been great. I’m typing this comment on my resurrected laptop. Thank you! Sue
