Edit Step 1 Lower Case  ¶ 

  • Remove the eight 4 mm Phillips screws securing the lower case to the MacBook.

Edit Step 2  ¶ 

  • The lower case is constructed of rubber-coated aluminum. Do not excessively bend the aluminum during removal, as any permanent deformation will cause tolerance issues after reassembly.

  • Slightly lift the lower case near the vent opening.

  • Continue running your fingers between the lower and upper cases until the upper case pops off its retaining clips.

  • The location of these three clips is shown in the third picture.

Edit Step 3 Battery  ¶ 

  • Use the flat end of a spudger to lift the battery connector up out of its socket on the logic board.

  • It may be easier to use your fingernails to lift up on both sides of the connector.

Unfortunately the tri wing drivers in Ifixit say 5mm however most folks including myself are wondering what that converts to in places that sell them Y0, Y1, Y2, Y3, Y4, Y5. Then some places like Harbor Freight sells 100pc kits for $9.99 (US) and include #0,1,2,3,4 tri wing bits. It also includes phillips P0,1,2,3 bits. Here's the link

If you never saw this company and you like tools, this WILL be on you bookmark list for sure!

rdesanti7,

I bought a tri wing y1 from Wera, but it was way to big.... I guess I'll buy the ifixit bit set, but otherwise I would try y0.

--edit-- Looking at the photo's here of the tri-wing screws, it more looks like my macbook has different screws. Mine are black and as large as the other normal screws.

Looks like the 2010 version has y0 somehow.

Peterdk,

I just replaced the battery on my late 2009 mac and thanks to this and all the other detailed guides it was actually quite simple (save for those cursed tri-wings). Don't feed apple with money you can spend on better things. A battery-removel isn't one of them.

For those that have questions about the size of the bit, every article starts with "Tools". The tri-wing is size Y1 as the guide says. 5mm is the length of the screw itself, not the size of the bit.

Just replaced a battery myself. The replacement battery (from an ebay seller) is supposed to be genuine, but was missing the "Warning, do not remove the battery" sticker and the "Do not throw in the trash" sticker, and the main sticker was glossy with air bubbles. Not sure if fake or not. But have been working great this first night.

This guide was spot on. Followed every step, and used the iFixit kit when doing the repair.

I just replaced the battery, using a battery and tools from iFixit, and the guide was perfect. Many thanks!

According to this page http://support.apple.com/kb/HT1651?viewl..., the 8 screws are not identical.

Can anybody tell me where each kind of screw is supposed to go?

"Tri-Wing Screws"? I don't see a "Tri-Wing Screwdriver" listed in the "Tools" section.

Just did it myself ;)

Hannes,

When I re-installed the battery, I inadvertently ripped the ribbon between the Trackad ribbon and the battery ribbon. Be Careful!
