Replacing the battery on your MacBook Pro 15" Unibody 2.53 GHz requires a 1.5 mm flathead screwdriver to remove the five-point Pentalobe screws securing it to the upper case.

Remove the following ten screws securing the lower case to the upper case:

  • Three Pentalobe screws secure the battery to the upper case. They can be removed with this special driver.

  • If you don't have a Pentalobe driver, a 1.5 mm flathead screwdriver can be used in a pinch. Be sure the head of your flathead screwdriver fits snugly across two of the five "points" of the screw head before trying to break the screw free, as a loose fit will easily strip the screw head.

  • If the head of your screwdriver fits too loosely, find a bigger bit and file it down until it fits snugly before proceeding.

  • You do not necessarily have to follow steps 3-7 to remove the battery in order to replace the hard drive. However, it is recommended to remove all power sources from electronics before working on them.

It really depends on how thick the 1.5 mm flathead screwdriver is. I tried a low-cost tool and almost destroyed the screw. So be carefull

Unfortunately, when I added a second hard drive via these instructions, all went well but Bluetooth is now MIA. Can anyone help?

I agree...

I have bought a used MacBook Pro, when problems arise, opening Corps was trying to turn the screw, but with poor quality could not turn a screwdriver, only to ruin the screw. Try to buy ifixit Screwdriver set. Good luck to all and thank you ifixit team for such assistance as ifixit.com. Thank you.

  • Remove the two exposed five-point Pentalobe screws along the top edge of the battery.

The screws holding my battery were all worn out since an earlier removal. So instead of ruining them even more I put some saran wrap on the tip of my pentalobe driver and gently unscrewed them.

  • Use the tip of a spudger to bend back the finger of the "Warning: Do not remove the battery" sticker while you remove the five-point Pentalobe screw hidden underneath.

  • Lift the battery by its plastic pull tab and slide it away from the long edge of the upper case.

  • Do not try to completely remove the battery just yet.

  • Tilt the battery back enough to access the battery cable connector.

  • Pull the battery cable connector away from its socket on the logic board and remove the battery from the upper case.

Changing this battery for a friend went as smooth as silk. I've done this many times before so that was no surprise, but now the battery (bought from ifixit) shows only 85% charge even after being left all night to charge, and the charger stopped charging and shows the light on the charger shows green.

What have we done wrong and what do we need to do about it?

You need to calibrate the new battery. Charge until it won't charge any more. Unplug the computer and leave it until it puts itself to sleep from low battery. Make sure your settings are as low a threshold as possible (3%) I think is the minimum. Then plug it in and charge back to 100%.

Further note: we tried running off the battery, and when it was at 44% tried to recharge it using another charger that we knew was working. The battery indicator says the battery is not charging.

It's possible to be necessary to reset the battery controller SMC.

It's the last step to do

If the battery is non removable (MacBook Pro from 2009) :

Shut down your Mac.

Unplug the MagSafe or USB-C power adapter from your computer.

Using the built-in keyboard, press Shift-Control-Option on the left side of the keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds.

Release all keys.

Reconnect the power adapter.

Press the power button again to turn on your Mac.

Si la batterie n’est pas amovible

Éteignez l’ordinateur.

Branchez l’adaptateur secteur MagSafe ou USB-C à une source d’alimentation, ainsi qu’à votre Mac.

À l’aide du clavier intégré, appuyez sur Maj + Contrôle + Option dans la partie gauche du clavier, et appuyez en même temps sur le bouton d’alimentation.

Relâchez toutes les touches, puis appuyez à nouveau sur le bouton d’alimentation pour allumer votre Mac.

Thanks so much for posting this great, well-written, and well-documented tutorial. Couldn't have done it without you. Probably just made me $2-300. :)

The battery I received has a pad on the bottom on one end that was not on the original battery. this interfers with the trackpad clicking mechanism. Did they send the wrong battery (it fits otherwise)? Should I remove this pad?
