Edit Step 3 Battery  ¶ 

  • 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.

Edit Step 4  ¶

Edit Step 5  ¶

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.

I found This guide has been found to be exceptionally cool.

My Mid-2009 MacBook Pro, the charge capacity has gotten lower in the past few months, I had gone through 600+ cycles. I also got a "replace now" warning on my battery icon in OS X. So, I figured it was about time to replace.

My Fix

Easiest time I've every had replacing an internal component. Just take out the access panel screws. 3 screws to take out the battery, unplug it, plug in the new one, 3 screws back in, and back goes the access panel. Clean and easy!

My Advice

Apple says the MacBook Pro 15" Unibody (Mid 2009) Battery on my model of MacBook Pro it not user replaceable. So, if you replace the battery yourself while your MacBook Pro is in warranty you may void it.

you can drop off your old battery at any Apple Store and they will recycle it for free!

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.
