スパッジャーの平面側先端を使って、バッテリーコネクターをロジックボード上のソケットからまっすぐ持ち上げます。
I have a friends MacBook Pro that has some water damage that caused the MacBook not to be able to use battery power, but still work when plugged into A/C. Upon further inspection I can see visible corrosion on a few of the 9 cables going from the battery connector to that small circuit board. Is it possible to just replace that circuit board?
Sometimes it can be enough to just clean the contacts without having to replace the entire board. Dosent work for complicated IC's like plcc type, where corrosion is underneath the chip. Here you will have to reheat and reapply the IC.
When placing the battery connector back into the socket on the logic board, check that every part of connector is pressed down. You should hear a soft click when it's back in place.

I thought I made sure it was connected but when running the computer it only detected the battery but couldn’t power it. I had to run with power adapter. Also it didn’t charge. I guess some pins were connected but not all. To verify that all were connected I removed the plastic cover, placed it carefully completely flat, and then reattached the plastic cover. After that it worked!
Lift from the long, flat side, not the shorter side. In this picture, you should lift from the NORTH part of the connector, not the WEST side like they are doing. This is because you can spread the pressure from lifting the connector across more area, as compared to the side. I accidentally broke off part of my battery connector lifting it up the way shown, but was able to do it the way I described without problem. Make sure to lift from the wide part so you don’t have my same trouble!
The connector is no more than 1mm thick… the socket is 3-to-4mm deep so make sure you’re trying to remove the connector itself, and not pulling at the socket.

You can do it from the side like the picture, but i would recommend twisting almost like a screw driver once you have leverage under the overhanging part of the left side like in the picture. Twist the tool so that it starts to put pressure on the top, until you’ll hear it click out. You can be somewhat forceful but it shouldn’t require a lot of strength. Guiding the tool with one hand and twisting with the other is a good way to attempt this.
After I put the battery back I found out at this step that the new battery connector was off by 2 mm (because I installed my battery slightly off). Since the connector is rigid, I removed it’s plastic cover (just like we all did in Step 4) to free the cable, which allowed me to bent it enough to properly plug the connector.
Well, I’m reading this step in the battery replacement repair guide, so it’s pretty critical to disconnect the battery from the main board. I’m guessing these steps are reused in other guides where disconnecting the battery might not be such an obvious need.

Also wondering the same. I came here from a link to replace the fan. Is it necessary to disconnect the battery inorder to replace the fan?
The connector wires from the battery to the connector are long
You'll have to bend them downward and into the small cove that exists so the connector can fit in place.
So use the a plastic card or flat end of the spudger to bend them downward and folded a bit back so the connector will fit in place.
Use your old battery as a guide for how they should be bent.Hi All ,
I followed the instructions step by step and changed the board successfully and reconnected everything back. When I powered it back on I can see it is charging again however it just displays a black screen and no display. Keyboard light comes on as well and the apple logo light on the back lid also turns on. Not sure what is wrong ? It has been charging for more than 15 minutes and still no joy. Anyone able to help solve or identify the issue .
Thanks
The connector cover is slightly wider and longer than the socket (<1mm) so there is a small "lip" around the top that can be used to lift it.
If your are not familiar with those repairs, and as with most of those connections, I recommend to take the time to observe your computer and the pictures from the tutorial, reading instructions and comments before starting each step. This battery connector needs both a bit of force and of precision. For a battery repair the connection of the new battery is a bit more tricky, you need to have your battery in the right position and to force it a bit the connector

If you miss or let this step for later like I did, the power left in the battery even though the computer is completely shut down, will screw up the I/O board cable like I did. I noticed this after I put all the pieces back, turn the computer on and surprise, no wifi hardware is detected. -.-
@sebasgaes, shoot, I'm only part way through the process, but I skipped this step thinking it wasn't necessary. I'm only through step 12 right now, but is there a fix if my machine doesn't recognize the wifi hardware after I've put it all back together? I don't see reference to the "I/O board cable" anywhere else in the instructions, so I'm confused about your mention of that...
UPDATE: I completed the job, rebooted, and all is well, wifi and all. Thanks anyway; gotta love iFixIt!!

A plastic foam cover also covers plug and socket and the whole battery. It is easy to remove it from the right side to the trackpad wire that the battery plug is free like shown in the picture. I kept it to use it again later.

I have done tons of these battery replacements.
You don’t need to do anything on the list after you disconnect the battery, apart from carefully moving the speakers out of the way, and then prise up the battery modules. I just very carefully, and with little even motions, use a large slot screwdriver. Being careful to keep it flat, to not puncture the battery.
Easy peasy. I have never had an issue after dozens of the tasks…

Dear Sir,
as you seem to be very much experienced with battery replacements you might perhaps give me a hint why after having removed the battery pack successfilly, the keyboard doesn't work anymore after booting the system. The Touchpad works, the keyboard backlight works but typing does not function at all.
I only disconnected the battery connector and touched nothing else. I am quite desperate …

I agree with Dave la Rose, provided you use heat rather than solvent to remove the old battery (or possibly floss, haven’t done that). Please see my comment further down this thread on how to use an iOpener for correctly heating the glue joint

After removing battery contact board plastic. My screwdriver accidentally fell and touched the battery board. And it short circuited. Now my battery doesn't charge. My laptop doesn't work without charger now. shuts after a few minutes of use. Can i fix it without sending it for repairs?

Is replacing the battery necessary?

How do we know if it's necessary to replace the plastic cover adhered to the battery contact board?
What are the factors that would require that?
