I can’t guarantee this will work for you, but this is what I did and was happy it worked out for me. This is another reason why not to use the double sided tape (or use sparingly) until you know your battery is good. I had to take my battery out at least 3 times and I became an expert at changing the battery. It is easy if you don’t tape and you break that plastic wall to get the cables under the logic board. Good Luck!

The next morning the battery voltage did not change (I think it was really low to start with - I recall less than 3v) so I was a bit disappointed but I put it back into the Mabookpro and did not start right away. Instead I plugged in the charger and left the charger on the MacBook Pro for the rest for the day (about 18 hours). Then I booted up the MacBook Pro and it worked! The battery was fully charged and would hold its charge and recharge no problem.Â

Your initial 73% charge reading was probably wrong, my did this too the first time I installed and when I unplugged because it wasn’t uncharging the computer went off like it had no battery power. Continued below…

Yes this also happened to me too! I think many of these batteries are older and will lose their charge over time, so if the new battery has a very low charge on it then there is a protection circuit on the board and it will not charge. Many lithium battery chargers have this as a safety precaution in case the battery is defective. This is what worked for me:

Remove the battery and the two gold tabs on the right that make contact with the logic board contacts (the ones that you but a screw in between) can be used to view how much voltage the battery is putting out. Just use a volt meter and you can also tell which contact is positive and which is negative. To add so voltage to the battery directly I just hooked this battery to a 12v trickle charger overnight. Be careful here! You do not want to overcharge the battery as this is very dangerous. Continued below….

Here is a link to a picture of the batter “wall” that you can break off and then glue back. This will save you from removing the logic board:

I exactly what Kerry did. You can break that “wall” and then you can easily slide the cable in under the logic board. Not sure what that wall does other than provide a stop from the bottom case pushing on battery. I glued it back and didn’t seem to have any problems. I did not use the double side tape to secure the batteries so it would be easier to change the next time. Don’ t know why apple has to put so much glue. Scraping off the batteries is the hardest part!

If you are changing the batter you don’t need to remove the logic board and you can jump to step 64. It can say you a lot of time. But there is one trick you need to do. It can be tricky getting the cable under the logic board but I ended up breaking the plastic “wall” that holds the centre battery and you can slide the cable in and just glue back the wall.

For me a T4 does NOT work - I needed a T3 Torx screwdriver.
