Introduction

Use this guide to safely remove the glued-in battery from your MacBook Pro with the help of an iFixit battery replacement kit. The adhesive remover in your kit will dissolve the adhesive securing the battery, allowing you to remove it with ease. The battery is made up of six distinct cells, four of which are adhered to the upper case.

iFixit adhesive remover is highly flammable. Perform this procedure in a well-ventilated area. Do not smoke or work near an open flame during this procedure.

For your safety, drain your MacBook Pro's battery before you begin this procedure. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured.

Note: The solvent used to dissolve the battery adhesive can damage certain plastics, such as the MacBook Pro's plastic speaker enclosures. Take care when applying the solvent.

If you're using the old-style iFixit adhesive remover with separate bottle and syringe (no longer sold), click here for a slightly modified set of instructions.

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

    • Two 2.3 mm P5 Pentalobe screws

    • Eight 3.0 mm P5 Pentalobe screws

  • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

Wedge your fingers between the upper case and the lower case.
  • Wedge your fingers between the upper case and the lower case.

  • Gently pull the lower case away from the upper case.

  • Remove the lower case and set it aside.

Add Comment

  • The lower case is connected to the upper case at the center, with two plastic clips.

  • During reassembly, gently push down the center of the lower case to reattach the two plastic clips.

  • Remove the plastic cover adhered to the battery contact board.

This plastic cover wasn’t included with the new battery so I placed the original one back in. Was it supposed to go back in? This detail wasn’t clear since the original cover didn’t fit exactly over the newer battery connector. Plus any stickiness of adhesive that may have been there was gone.

  • Remove the following screws securing the battery connector board to the logic board:

    • Two 2.8 mm T6 Torx screws

    • One 7.0 mm T6 Torx shouldered screw

Top screw in this image was not a T6. I found that a T5 bit fit this one.

  • Remove the wide head 6.4 mm T6 Torx screw securing the battery connector to the logic board assembly.

I lost this screw! How important is it? Will it be okay with just the 3 previously removed screws?

  • Carefully lift the battery connector board up off the logic board.

  • It is recommended to bend the battery cables just slightly, to keep the board suspended up above the logic board and out of the way.

  • Do not fold the board completely over, or crease the cables, as this may damage the battery.

  • Grasp the Interposer with tweezers.

    • An interposer is the name for an interface that links one electrical connection to another. In this repair, it is the board connecting the battery to logic board.

  • Lift the Interposer off the logic board and remove it.

    • Removing this board will ensure that the battery remains disconnected throughout your repair, preventing your computer from accidentally powering on. It's also a good idea to take it out so it doesn't fall out unexpectedly.

WHy to remove battery contact board? Replace can happen without it also, right.

  • Use the flat end of a spudger to pry the right side of the I/O board data cable connector up off its socket on the I/O board.

  • When prying the I/O board data cable connector from its socket, make sure to pry the connector itself and not the socket. Prying the socket may cause irreversible damage to the I/O board.

  • Wedge the flat end of a spudger beneath the left side of the I/O board data cable connector.

  • Gently twist the spudger to disconnect the I/O board data cable connector from its socket on the logic board.

This step is NOT really necessary. The trackpad can be removed with this cable still in place.

  • Use the flat end of a spudger to pry the SSD cable connector up from its socket on the logic board.

  • Move the SSD cable connector out of the way.

Because it is attached to the battery with a tiny bit of tape near where the spudger is in the picture, this cable should probably be loosened. But it is NOT necessary to remove the speaker entirely.

Robert - Reply

  • Wedge the flat end of a spudger beneath the right speaker cable connector.

  • Gently pry the right speaker cable connector up off from its socket on the logic board.

  • Be sure you are prying up on the connector, not the socket itself.

When reassembling be careful that the right speaker wire is flush against the battery. At first, it was slightly touching the airport/bluetooth board causing wifi and bluetooth to not work after restarting.

  • Remove the following screws securing the right speaker to the upper case:

    • One 6.8 mm T5 Torx screw

    • Two 6.3 mm T5 Torx screws

  • The corner screw may be covered with a foam pad. If so, use your tweezers to peel it up and remove it.

There are two 6.8mm screws, both fit to the side of the Macbook.

Be very careful on this step. If you aren’t you can snap the plastic on the corners where the screws go in. Remember to go slowly when spinning the screws back in, it doesn’t take gorilla torque to tighten them, just take it easy!

  • Now that your MacBook Pro is fully prepped, it's time to prep yourself.

  • iFixit adhesive remover contains acetone, a mild skin and eye irritant.

    • Wear eye protection when handling and applying the adhesive remover. (Eye protection is included in your kit.)

    • Do not wear contact lenses without eye protection.

    • Protective gloves are also included in your kit. If you are concerned about skin irritation, put your gloves on now.

  • Pull off the black rubber stopper from your bottle of adhesive remover.

  • Twist to loosen or remove the bottle cap before you cut the applicator tip.

    • This unseals the bottle and allows the pressure to equalize before you cut the applicator tip. If you skip this step, the adhesive remover may spray out unexpectedly when the tip is cut.

  • Use scissors to cut off the sealed tip of the applicator.

    • Cutting close to the narrow tip will give you better control so you can apply the adhesive remover in small amounts.

  • Twist and close the bottle cap securely before you proceed further.

Add Comment

  • Apply a few drops of adhesive remover evenly under the edge of the leftmost battery cell.

    • You don't need to use very much. The small bottle contains more than twice the amount of solvent needed to remove all the battery cells.

  • Wait 2-3 minutes for the liquid adhesive remover to penetrate underneath the battery cell before you proceed to the next step.

Add Comment

  • Insert the flat edge of a spudger or plastic card underneath the leftmost battery cell.

  • Run your tool along the bottom perimeter of the battery cell and lift to begin separating the adhesive.

This is the most difficult step. The tip of my spudger got bended and the aluminum case damaged it.

Ahmed Almulhim - Reply

I also broke a spudger trying to do this. Eventually I figured out it is easier to go in diagonally from the corner, just to one side of the screw hole, and lever until you hear the adhesive pad tear and give way.

Matt Sephton - Reply

we use a hair dryer and gently blow hot air in between the battery for a good minute before trying to lift it with a spunger. It worked wonderfully! When lifting, just give it constant force upward and you'll hear the battery slowly breaking away from the macbook, and we don't even see glue residues on our macbook at all. Just be patient. :)

Allen Lin - Reply

Just a note to say that the above comments were written before the liquid adhesive remover was added to the guide—you should definitely NOT be breaking any spudgers using the current procedure, which requires very little force. I recommend using plastic cards rather than spudgers—it's pretty easy to slide them under each battery cell and separate the adhesive once the solvent has done its work.

Jeff Suovanen - Reply

This is much easier to do using a plastic card. Just slide the card under the side of the battery and rock it back and forth. The battery will separate pretty quickly with minimal residue.

by a plastic card, do you mean a credit card type thing? thanks in advance.

Exactly—one of these or an old credit card should work fine.

  • Repeat the above steps to separate the adjacent battery cell from its adhesive:

    • Apply a few drops of liquid adhesive remover under the battery cell.

    • Wait 2-3 minutes for the adhesive remover to penetrate and soften the adhesive.

  • Switch sides and repeat the above procedure for the two battery cells on the right-hand side of the MacBook Pro.

    • Remember to add a small amount of liquid adhesive remover under each battery cell, and wait 2-3 minutes for it to penetrate before prying up the cell.

    • Be careful not to puncture or otherwise damage the battery cells.

Puncturing the battery’s protective covering can lead to release of caustic fumes or fire.

Chris Leeds - Reply

  • Lift the battery as a whole up out of the upper case, and remove the battery.

  • Before installing a new battery, remove all the old adhesive from the MacBook Pro's case.

    • With a little luck, you can slowly pull out each strip of adhesive with your fingers.

    • Otherwise, soak each section of adhesive with a bit of adhesive remover for 2-3 minutes, and then scrape it out with an opening pick or one of the other tools in your kit. This can take quite a bit of work, so be patient.

    • Mop up any remaining adhesive remover and give your MacBook Pro a few minutes to air dry.

  • The replacement battery included in your iFixit kit comes with adhesive pre-installed. Test the battery's fit and alignment carefully before peeling off the film covering the adhesive, and then press each cell firmly into place. If any additional films/liners are present that weren't on your original battery, remove them now.

  • Calibrate your new battery before using it: allow it to drain overnight, then charge it to 100% and drain it again until your MacBook Pro shuts down automatically. Charge it again and use it normally.

  • If you notice any unusual behavior or problems after installing your new battery, you may need to reset your MacBook Pro's SMC.

During battery replacement take care to position the two left and right battery packs inwards and upwards towards the macbook center such, that there is sufficient space for reinstallation of the two speakers!

When you are at this step and before you put the new battery in, take the time to clean your computer really well. You will be surprised how much dust/dirt and even pet hairs have gotten into your computer. After I removed the battery, I use a little more of the acetone to clean the bays up and after it dried, I used a tiny bit of Isopropyl Alcohol to make sure there was a good clean area for the new bonding. Make sure you clean the fans. Don’t use a toothbrush or anything like that. If your have a Lowes or Home Depot, you can buy a shop vac attachment kit for about $20, it’s well worth it. Don’t use that air in a can crap, it will put moisture on circuits. Take your time, it’s not a hard task to do everything, just use a little patience.

thanks to everyone for the helpful comments along with this really good tick list of things to do. The main thing I have learned is, I don’t have the patience to do this so I am taking my macbook pro (early 2013) 90 odd miles to my nearest Apple store with a Genuis bar. They can sort it for me. They might charge a lot to do it, but at least it will be them risking messing the process up not me! Thanks again.

Followed this guide step by step. Very comprehensive and accurate. I would never have dared disconnect the speakers if this guide didn't show me how.

One point though. The lower left and right speaker screws had some metallic sponge on top of them. I wouldn't have known there were screws underneath.

Excellent guide. I'm a repair technician who works on both PCs and Macs. This was my first rMBP battery replacement and I wasn't sure what to expect. For those experienced with electronics repairs, I'd say this is a relatively easy repair with the exception of releasing the adhesive which holds the battery cells to the case. I was eventually able to do it with a spudger and some elbow grease, but I was worried at times that I was going to puncture the battery. Apple really needs to dial back the strength of adhesive they use for these applications. They are clearly making it as difficult as possible for the average user to attempt, which IMO may end up costing them well informed and thoughtful customers. This setup is similar to the iPhone 6 battery (which I actually did puncture with a spudger the first time I removed one) albeit more involved to remove. In the case of the iPhone, a few minutes on the hot plate loosens it right up but this isn't really feasible in the case of the rMBP.

Thanks for this guide, I had a faulty battery and replacement by apple would be 400 euro. Now I did it myself with a replica battery for 80 euro.

Tip on prying loose the battery at step 24 and on: Use an old credit card. That worked very well for me.

roelofk - Reply

Old Credit card works very well on Step 24. Excellent guide.

Tiny AIM - Reply

I recommend to skip step 14 ( pry the left speaker cable connector up off from its socket on the logic board). The risk of damaging the socket is very high. There is even a warning in this guide (Be sure you are prying up on the connector, not the socket itself!).

Proceed from 13 to 15 and 16 to remove the right speaker. Still with the connector in place you can put the speaker a bit aside and have enough room to remove the battery packs in the steps later.

Same for left speaker and its connector cable (step 18).

Hint by @roelofk with old credit card is very helpful.

Excellent description and excellent pictures. Thx

Apple should not put Adhesive most specially the time you spent to remove it. Its easy but it takes time cause the adhesive is like a glue, If somebody

read this the tactic is borrow a Hair drier from your wife and heat this Bad Battery really hot and start inserting the Plastic or whatever you have underneath the Battery slowly. Apple should just put some kind of anti static foam so its easy to remove in no time theres cover anyway that foam will keep it from moving period thats it.

ricofamor - Reply

Excellent guide, it worked very well for me, the parts and tools I purchased here made this job easy and a pleasure! Getting the batteries unstuck from their glue is the hardest part for sure, just patience and proper tools and it doesn't take too long though. Thank you so much!

Excellent guide, but PLEASE consider changing the reported difficulty to medium (iFixit, if that's not something the author can do). The process is actually super easy, but just takes over an hour to do.

I nearly didn't do it myself after realising it was rated the same difficulty as an SSD/HDD change in an iMac (with which I cracked my screen in two places), but it isn't. This is about a 2/10 difficulty level, and that's about 9/10.

I just think it would be a shame if the reported difficulty dissuaded people from doing it, and wasted hundreds of dollars paying Apple to do it. If you can read, and have the equivalent dexterity of tying shoelaces, you can do this. :)

Also, the battery removal is a pain, but if you cut an old credit card down the middle, you have two "spudgers" you can use underneath in a turning motion (sort of like rotating a lever in-plane), while pulling it in and out. A bit of patience and you'll get each half out in about 5 minutes.

LongTimeMacUser - Reply

Great manual! Thanks a lot. I do agree with @longtimemacuser tough, difficulty level was discouraging me. Once I read all the steps, I thought I could do it and I did it and it worked! So I believe this difficult level should be medium, it's not hard (expect for the battery adhesive), it just take a long time to do it.

I had a water incident with my wife's Macbook Pro. After drying the machine it would startup on power but the battery was toast. It said the battery needed replacing. Went through this battery replacement procedure - agree with the posts above that it's not as difficult as I was expecting based on the difficulty level.

Incidentally - after battery replacement the battery charged once then after that the machine wouldn't boot at all. I eventually went through this procedure a second time then removed the logic board and the i/o board and liberally cleaned both with a 99.9% isopropyl alcohol bath. Reassembled all the components and everything works great. I assume this was due to some residual water damage and the cleaning seemed to do the trick.

Kids got a new spill resistant chromebook new and the wife's Macbook Pro is happy again.

Very clear instructions, I followed them carefully and everything worked out fine! It was quite easy, actually.

I only improvised by using my nail polish remover (acetone) as an alternative to adhesive remove, worked as expected though :)

Been repairing Apple laptops on a regular basis for about 17 years now but this was my first ‘Retina Battery Adventure.’ As a long-experienced Apple tech, this really isn’t a very hard job. Just use the adhesive remover very carefully. It does all the hard work.

I bought iFixit’s ‘kit’, which turned out to be a great value; the replacement battery along with a spudger, precision tweezers, a syringe, a super-precision nozzle (for the syringe), small jar of adhesive remover (I think it’s just Acetone nail polish remover ), gloves, pry tool and pry pick, two pry cards, eye protection… oh, and a tool handle like the one in my iFixit universal toolkit, along with all the screwdriver bits required for the repair.

With all the extra pry tools and stuff, it looked like prep for a journey to the center of the earth or somethin’.... And hey, I was NOT disappointed when the job turned out to be waaay easier than implied by all the extra tooling. A nice collection of extra stuff for my kit! I now have two spudgers.

Wow.

Wonderfully comprehensive and easy to follow. I was able to remove the old battery and install a new one in around 1 hour. Take your time, read all of the instructions and look at all of the images a couple of times before starting. I separated all of the screws and labeled them so reassembly was a snap. Huge thanks to the author and to this site for offering the parts and detailed guide! My Mac is like new again.

I did this battery replacement this morning. If you follow the excellent instructions and take your time this is not very difficult. One thing that wasn’t covered is that the replacement battery comes attached to a piece of plexiglass to aid in the positioning of the 5 pieces of the battery. The quality control on the positioning was not perfect on mine - I had to detach half and position, then place the other half. The placement of the replacement is not covered in the instructions - but isn’t very difficult.

I recommend getting the full kit - it was complete and made the replacement go easier. My new replacement is charging to 97% and has a capacity of 6358 mAh. This is almost 1000mAh more than my original battery was reporting! My old battery was only lasting an hour, this one is reporting 4+ hours.

Thanks! Great documentation and a solid kit.

Thank you for a great guide! I was a bit worried about this, as it was rated Difficult, but it was not bad at all. I have been working on computers for many years, but had never cracked this model of MBP. My 13-year old daughter assisted me with the “transplant”, and all went well. (She has repaired a few iPhones for friends.) My old battery was only lasting a little over two hours, and I hope I have a significant increase in charge time with this new battery. Changing the battery took us about two hours, the longest amount of time was dealing with the adhesive. We found that the card provided worked better than the spudger, and the cloths in the kit were perfect for getting the remaining adhesive off after removing the battery. My daughter got to learn a new skill, and is confident that she could replace the battery in her MBP.

Zunächst mal großes Erlebnis, wenn das Paket mit all dem passenden Werkzeug und dem Akku ankommt. Alles hervorragende Qualität. Mal abwarten, ob der Akku hält, was er verspricht.

Die Anleitung ist sehr gut geschrieben, allerdings klappte der Akkuwechsel wesentlich leichter, als angekündigt. Hier ist keine Zauberei erforderlich. Nur gute Vorbereitung. Was Sinn macht: Ein Foto vom offenen Laptop machen, auf DIN a 4 ausdrucken, dann kann man die Schrauben immer an die richtige Stelle legen (am besten mit Klebeband fixieren, zB. den PRITT-Roller).

Stellt Euch einen Staubsauger zur Seite mit weicher Bürste. So könnt Ihr sehr vorsichtig die Berge an angesammeltem Staub entfernen, die sich im Gerät abgelagert haben.

Ich würde einen Hinweis begrüßen, dass die Akkus beim Einbau möglichst nah an den inneren Rand eingesetzt werden, um den Einbau der Lautsprecher zu erleichtern, die sind sonst sehr unter Spannung.

Ach ja: Der Akku wird dank eigener Platine als neuer Akku erkannt und die Anzahl Ladezyklen mit 1 angegeben.
