Don't pay Apple to replace your worn out battery. Do it yourself!

Image 1/1: Seven 3 mm Phillips screws.
  • Remove the following 10 screws securing the lower case to the MacBook Pro 13" Unibody:

    • Seven 3 mm Phillips screws.

    • Three 13.5 mm Phillips screws.

It looks like you need a Phillips #000 screwdriver for the 10 bottom screws. I tried the #00 and it's too big. Good thing I bought a 23 piece precision screwdriver set or else I would have been screwed.

The 10 screws that hold tha bottom case take a #00 Phillips driver, if yours doesnt fit it's probably because it's cheaply made & not precise enough. The only thing that I needed a #000 driver for was the keyboard screws. They're so small they look like specks of dirt or sand. I stripped out 4 of them & now will need to grind the heads off with a Dremel/rotary tool. The other thing that sucks is iFixit doesn't have a tutorial for keyboard replacement!

A true Phillips head screw's slots are rounded at their inner corners, to allow the screwdriver to "cam out" (pop out) of the screw head before you apply too much torque and strip the threads in the part that you're torqueing the screw into. However, the screws used in the Macbook don't have those rounded inner corners, so they're not Phillips. Instead, they may be a Japanese standard known as JIS B 1012, or a Frearson (also known as a Reed & Prince), but that's a less common design. Maybe technically these non-Phillips screws should be used with a screwdriver that was specifically designed for them, but they can be properly removed and reinstalled using a truly precision-made Phillips #00 (some people find a #000 sometimes works even better) whose tip comes to a sharp point--not the lousy fake "precision" screwdrivers that are sold in too many places. See my next comment for more.

Many screwdriver manufacturers get away with marketing fake "precision" screwdrivers because, in the words of the Wikipedia article at https://en.wikipedia.org/wiki/List_of_sc...: "Most heads come in a range of sizes, typically distinguished by a number, such as "Phillips #00" or "Torx T5." These sizes do not necessarily describe a particular dimension of the drive shape, but are often arbitrary designations in the same sense as a "Size 8" dress."

In other words, the quality of many "precision" screwdrivers is poor. In my experience, one of the biggest problems with many fake "precision" Phillips screwdrivers is that the four blades at the tip are often too wide, and their width may even vary on the same screwdriver (they're not supposed to). So just because a screwdriver is marketed as a "precision screwdriver", it may not be, and many that are labeled as #00, or even #000, will not work for a Macbook's screws. See my next comment for still more.

One of the best manufacturers of precision screwdrivers is Wiha (http://www.wihatools.com/tech-tools/prec... cost more, but they're worth it. Or buy screwdrivers from iFixit, who seem to be selling JIS screwdrivers.

Another article with some good info on screw and screwdriver types:

http://www.instructables.com/id/When-a-P...

Also keep in mind that some screws are tougher to remove and reinstall because they have a thread-locking compound on them, which is usually blue.

johnsawyercjs -

Phillips #00 is the correct screwdriver for the lower case. Maybe the one you have is worn or badly made.

Perfect man!Many thanks!:)

Compare the short screws carefully before reinstalling them. The shouldered screws go in the holes on the front edge.

twisk - Reply

thanks twisk, I wish i would have read your tip before I finished putting the bottom of my laptop back together. I managed to get all screws in somehow, but one was in fact too-tight.

BTW, big big thanks to the Author: Andrew Bookholt. Just used this guide and my trackpad now works again.

i too need a #000 for the bottom of the case -- i got the recommended screwdriver (#00) and unfortunately it's too big

plins718 - Reply

Before I started removing any screws I took a piece of paper and drew the bottom of the laptop and put a piece of double-sided tape in the spot where each screw goes. That way when I took out the screws, I could put them on the tape so I knew exactly which screw went in which spot. I did the same thing for dismantling the inside on another sheet of paper, then a third sheet for the screen after getting the front glass off.

mastover - Reply

I use a similar technique: I print out the iFixit manual for the job, and Scotch-tape down the screws/brackets/cables I remove at each step next to the component descriptions. That way, when I'm reassembling, the bits are taped right next to the photo of where they came from.

adlerpe -

That's exactly what I do for all my repairs! It's the best way to keep track of all of the parts ' original location and to make sure that you don't miss any parts during reassembly.

Great idea and one I use often

Excellent idea! Thanks for sharing it here.

The colours you used for these circles are indistinguishable for colour-blind people. Please consider using something like the palette suggested by visibone: http://www.visibone.com/colorblind/

Eric Sorenson - Reply

Squares, Circles, Triangles (you get the idea) would work as well to distinguish the different screws.

danzeitlin -

I'd use a Phillips #000 screwdriver also. The #00 can work, but if the screws are in really tight, it doesn't get far enough down into the screws to get purchase, so it will start to strip (and I agree that the screws are pretty soft). On mine, the screws for the fan were really tight, started to strip with #00, needed a #000 and quite a bit of pressure to get them to move.

jonathanmorgan - Reply

I thought it took a 000 as well. However, I tried both and realized the 00 works best.

Hi i was wondering if you can add 16gb to this model? or is 8 the maximum?

Igor - Reply

The Mid 2010 MacBook Pro 13" does support 16 GB RAM, but it is very picky about the type of RAM. OWC sells a 16 GB kit (2x 8 GB). I think it's got to be 1066 (aka 1067) MHz RAM. A lot of 8 GB modules on the market now are faster than 1066 MHz, and reports I've read say people start getting kernel panics if they use the wrong RAM.

Some info here:

http://www.everymac.com/systems/apple/ma...

"1066 MHz PC3-8500 DDR3 SDRAM"

"*Originally, both the official and actual maximum RAM was 8 GB. However, as confirmed by site sponsor OWC, if running OS X 10.7.5 or higher, updated with the latest EFI, and equipped with proper specification memory modules, this model can support up to 16 GB of RAM."

Our Mid 2010 already had "the latest EFI" (i.e. Boot ROM version in System Profiler), so the reference to updating it may not be relevant.

I used a 00 that fit but the screws were very tight so I used a tiny paintbrush with some wd40 on it and put it around the edges of the screws. Worked like a charm

valentinedhdh - Reply

I had the same problem. The #00 screwdriver worked for some of the screws but some others were too tight and I had to use a #000. Maybe it was because the cover had slightly bent because the battery inside had basically doubled its width, but I still found that the #000 was a much better fit for these screws. Even the ones that came out with the #00 came out much easier with the #000. I would suggest updating this guide to suggest using a #000.

Had no idea they were so expensive.

Franklin - Reply

Phillips #00 is the right tool for all the steps (Except the 4 HD T6 screws). Maybe there is dirt in the notch.

There is any chance to use the Toshiba MQ01ABD 1 TB 2.5" Internal Hard Drive MQ01ABD100 , it has7200 rpm , shuold it work?

If you are running OS X 10.11.2 or newer, battery provided by iFixIt will not work. I've already tried 2 batteries from iFixIt and neither worked. iFixIt needs to come clean on this unfortunate situation. I've already put 8 hours into this futile effort when it should have taken me 45 minutes.

What was your solution? I'm using 10.11.3 OS X. I may need a battery replacement very soon too.

<i>The 10 screws that hold that bottom case take a #00 Phillips driver, if yours doesn't fit it's probably because it's cheaply made & not precise enough.</I>

I purchased the IFixIt 54 bit Driver Kit and their Phillips #00 are <b>NOT</b> the appropriate size for the bottom screws on this MacBook Pro. This manual needs to have the tools changed to Phillips #000 Screwdriver. Until then I shall not click the "Give the author +30 points" button. Apart from that, the rest of the manual is very good. It would also be an idea to make a comment about making sure the battery connector is in the correct position when plugging the battery back in. One poster commented that their battery will not charge anymore. My guess is a pin(s) was/were bent due to the connection not being in the vertical orientation when being pressed back together. :-)

THANK YOU for writing and generously supplying this guide for our use. It is much appreciated. +30 point coming when the Phillips #000 size is changed or added.

  • Remove the following tri-wing screws securing the battery to the upper case:

    • One 5.5 mm tri-wing screw.

    • One 13.5 mm tri-wing screw.

Where can I buy 5.5 mm tri-wing screw and 13.5 mm tri-wing screw ?

gansodesoya - Reply

I have the same question? Where can you buy new screws. Apple put in these rediculous tri-screws.... The short one went in crooked and jammed. I couldn't get the long one back in at all, not sure why, but it's not catching a single thread.

My 2nd question is, what the alternative if you can't get the screws back in (e.g. some kind of tape). With only one screw only half way in and jammed, the battery doesn't seem to be moving around, so I think I'm ok, at least for now.

Mike Mullally -

similar issue here, I'd like to buy these bolts new. and it would be even better to buy new ones but with a philips head, not a triwing head. please let us know. thanks.

You can get the tri-wings from ifixit directly - Tri-point Y1 Screwdriver

or get the whole kit (like I did - it's excellent) - Classic Pro Tech Toolkit

Did everything correctly, but now the battery doesn't charge. Do I have to do something in particular to make it work now that's installed? Thanks

Olivier - Reply

I am answering a 2 year old post but this is for those who may have the same or similar issue in the future.

When I was putting the battery connector back on that it didn't sit flat against the board before I put pressure on the top of the connecter to press it back into its socket. I then took time to examine the battery connector socket and saw it consisted of long thin vertical pins. I deduced that if the battery connector was not aligned correctly to the pins on the motherboard then it may be very easy to bend one or more of the pins in a way that they wouldn't mate up with the opposing female part on the connector. That sure would cause a battery charging issue. If you feel too much resistance when pressing the connector back into the socket then stop and make sure it is all aligned correctly. I know, not easy with the size, the black connector and black socket. A spudger can be used on the battery side of the connector to raise it to a level position prior to applying pressure to the top of it.

Joseph King -

Everything was so easy but that is not the highlight of it all; the replacement parts are cheaper than buying it from a local store here in Taiwan or in The Philippines.

My laptop wouldn't believe the battery was new until I reset the SMC as well ( http://support.apple.com/kb/HT3964 ).

once the battery is replaced with a new one, should it be drained? or charged full?

Myth. Charge it to where think you need the power level to be for "the beach" let's say and then charge it again at your room/in your car if you have the means/the bar with the right adaptor/ hotel lobby/ some hot opposite's room? Wait...

Apple is currently replacing battery for mid 2009 macbook pro for $129.95 no labor. If you've got a store nearby, not a bad option to get them to do it right and test to make sure battery, and not have to worry about the tiny screws. I've received two different reports however - 1 genius told me they could replace while I wait in about 20 minutes. Another told me I'd have to leave it over night.

John - Reply

Perfect! I didn't want to wait for the Tri-wing screwdriver to ship, so I gave it a try by wedging a FH 1 in between two of the wings. It worked well to unscrew, but you must be very careful when resetting the screws that hold the battery. If you get them started with your finger (a little pressure with your thumb pushing straight down will get the job done) then you can do a few final turns with the FH 1. If you try to start resetting the screws with the off-center-FH1-workaround, you will strip the screw! Keep the screws centered and don't force anything.

worked like a charm. my old battery had bulged and made it so that the track pad would not click :-( replacing the battery did the trick.

My local Apple Store wants $179 plus tax to change this battery, AND I have to leave my laptop for "a couple of days." This is one store that clearly doesn't get it (Cherry Creak Mall, Denver). Thus, a DIY fix is mandatory... but, they won't sell just the battery.

channonholiday - Reply

iFixit sells the battery you need for $119 (MacBook Pro 13" Unibody (Mid 2009 to Mid 2012) Battery), and once you get it, doing the replacement shouldn't take more than 30 minutes, even if you've never done a repair like this before.

I followed the instruction carefully and the battery works great. However, now my trackpad won't depress in all but the lower right corner. Anyone know how to fix this?

john - Reply

I found out the battery tab screw holes are slightly misaligned by about 1/2 mm. This causes the battery to wedge in too tightly to the track pad which is directly above. Using a small drill bit I moved the holes slightly allowing the battery to move slightly toward the center of the laptop. This took the pressure off the track pad. Also I took the clear plastic covering off as well. It works great now.

john -

The longer tri-wing bolt won't fit properly into the new battery I got through ifixit. The hole is too small and appears the wrong shape. It seems like this was the case with the old battery too, as there a crack in the corner near the hole where someone had to widen it. In the end I used the tip of a metal knitting needle (the sturdiest thing of the right size I had to hand) to widen the hole slightly, causing a similar crack. I guess since the bolt's thread is only at the tip where it enters the metal laptop casing this shouldn't affect how securely the battery is joined.

I had no joy with a 00 Phillips either, but this was probably due to the crappy quality of my socket set.

I added this battery on my Macbook Pro 2009 edition. I still only get 2 hours of online video (youtube or netflix). is that normal? And the Maximum Capacity of my battery is 93% at arrival??

Any tips to increase the battery life of my laptop? I don't mind going back to mavericks or earlier versions..

If you buy this battery new from OWC (macsales), they include--for free--the two screwdrivers you will need. Got this battery today for 99.00, installed it myself based on this instructional in 10 minutes. And I have never opened a macbook before, first time. The main things: don't lose the screws, most of them are incredibly tiny (I lost one when dusting with microfiber), don't forget to put the screws back on battery housing, and be gentle and patient when removing small, semi-rigid battery wire cable. Best wishes.

I bought a new battery from ifixit.de, was around 100€. I have to say I'm a bit dissapointed, charge is nowhere near full it's around 3500, battery barely manages an hour and a half. Have to say it was not worth it. Cocconut battery says it's 3,1 years old and lost around 20-25% of it's original capacity. I feel I got robbed for 100€

Mario Markovic - Reply

Thank you SO much.

This was easy and worked very well.

I used a battery from Duracell Direct, which cost £50 (inc. delivery) which has a one year warranty.

I took the opportunity of cleaning the inside while it was open, using a soft sable-hair paintbrush, to lift the dust off the circuit board, and a microfibre cloth on the inside of the case.

It read 46% charge when first put in , (which may not be correct until it has calibrated itself) which dropped on use to 18%, and has recharged happily and just now it has reached 100% - brilliant!

Thanks again,

replaced optical drive with 250GB SSD.

replaced 2x2GB RAM with 2x4GB.

replaced old battery..

Things work, except the fan never slows down and makes a lot of noise.

The fan start at full speed as soon as I click the power button, even before the screen lights up.

Please help.

Also the bluetooth and camera stopped working :(
