Introduction

This guide contains instructions for using the old-style iFixit adhesive remover with separate bottle and syringe, which is no longer sold. For the updated version, click here.

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.

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 will damage your speakers if it comes in contact with the plastic speaker enclosures. This guide instructs you to remove the speakers before proceeding to the battery.

    • Remove the following pentalobe screws securing the lower case to the MacBook Pro:

      • Eight 3.1 mm

      • Two 2.3 mm

    The number of screws listed here is wrong on my model. I had four of the smaller size.

    Just to add to my comment above (I can't edit it because it's anonymous), my MacBook Pro is a mid-2015 15in model 2.8GHz (A1398; EMC2881). For the bottom case it uses six 3.1mm screws, and four 2.3mm screws at the clutch/hinge side of the MacBook Pro. I tried using a 3.1mm screw at the clutch/hinge end, as described in the main article, and they don't fit. It has to be four 2.3mm screws.

    Removing the screw will void warranty?

    Ok, so here is what I discovered. There is no mobile application for these instructions, while having them on a computer is nice but when the computer you have is the one you are changing the battery on these instruction are of no use. I advise coping them and then paste them in PDF and print them out. Or you better have a photographic memory. I’m just saying.

  2. Lifting from the edge nearest the clutch cover, lift the lower case off the MacBook Pro.

    • The lower case has two plastic pegs (red) that fit into plastic clips in the upper case (orange).

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

    pretty hard to put it back, so I just remove the clips on the upper case....

    The trick to putting it back on is to guide your fingers to the same level as the clips, and then when you put the case down move your hand from the left side of the case to the right side of the case; applying pressure when you reach the area where the clips are.

    • Peel back the sticker covering the battery connector.

    You only need to remove the tape to the edge of the flap. This is enough to be able to pry the battery connector up.

    • Gently lift each side of the battery connector to pry the connector out of its socket on the logic board.

    • Bend the connector back toward the battery, ensuring that the battery connector doesn't accidentally make contact with the logic board.

    why is this necessary to remove a hard drive?

    @lawrencetaylor On any electronics repair, you need to disconnect all sources of power before you start. It’s a basic safety precaution and also removes the risk of accidentally shorting a connection somewhere (which can potentially kill your MacBook).

    • Use a spudger or tweezers to pry the three AirPort antenna cables straight up off of their sockets on the AirPort board, and bend them up and out of the way.

      • The cable connection points are fragile. Be careful to lift only on the connector, and not on the socket or cable.

      • To reconnect, align the connector carefully into position over the socket, and press it down firmly with the flat of your spudger.

    I seriously hate this step - it is pretty much the only difficult part of the job. Reconnecting these microscopic stinkin connectors is a monumental PITA…

    Guys, be very carefull with these 3 cables.. If you are not going to replace the whole display, just be careful as much as possible.

    When reconnecting these tiny wires, use one hand to guide and align the connector by holding the wire and the other hand to press them down with a flat end of a spudger. Spent 10 minutes figuring it out and connecting the first one, then only a few seconds on both of the remaining connectors :)

    If you try to do this with one hand, it’s extremely easy to move them out of the alignment while pressing them down.

    I think there is a better way - where you disconnect the wifi card using the black screw in middle of wire 2 and 3 first and then untie these connectors. I pryed away the connectors but the sockets on the card were all damaged during the process. Ended up having to get a replacement card before reassembly could be completed. So again there are 2 components - connectors which are being pryed away and really fine and delicate socket. Very easy to damage them. Better to take the card off and delicately peel these connectors off. I would not recommend using these pry sticks mentioned here for that.

    ATTENTION ! Cette étape est grandement sous-estimée, aucune mention de la délicatesse de l’opération contrairement à d’autres étapes bien plus facile… De plus, il semble possible de sauter cette étape en déconnectant seulement la carte comme expliquer sur la version anglophone du guide !!! J’ai endommagé le connecteur le plus proche du ventilateur, pour rien… Heureusement, tout semble fonctionner correctement…

    • Pull the display data cable straight out of its socket on the logic board.

      • Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.

      • Do not touch the contacts on the data connector or its socket with your fingers or any tools, as you may deposit oils or damage the pins.

    • Gently bend the display data cable toward the display hinge, to expose the screws on the MagSafe 2 board.

    • 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.

    • Open your container of adhesive remover.

    • Fill the syringe included in your kit with a small amount (approximately 1-2 milliliters) of adhesive remover.

      • It's best to fill the syringe with no more than about 1-2 milliliters of adhesive remover at a time, so as to avoid accidentally applying too much.

      • Refill your syringe as needed throughout the rest of this procedure.

    • Lift and remove the battery.

    • Before installing your 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 strip of adhesive with a bit of adhesive remover for 2-3 minutes, and then scrape it out with a plastic tool. 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 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.
