Introduction

Use this guide to remove the glued-in battery from your MacBook Pro. This is best done with the help of an iFixit battery replacement kit; the liquid adhesive remover in your kit will dissolve the adhesive securing the battery, allowing you to remove it with ease. Alternatively, you can use an iOpener to apply a modest amount of heat in order to soften the adhesive before prying out the battery.

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.

For all the screws you use the P5 pentalobe screwdriver?

Pentalobe is only for the screws on the bottom cover. The Torx screw driver is for the remainder.

Is the Pentalobe screwdriver mentioned in the tools list? I did not have one so I used a filed down flat blade screwdriver. Not a fantastic idea, but it works.

Alex Birkett - Reply

Yes, it's mentioned on the top of this page. P5 Pentalobe to be precise. I didn't have one either, so I bought one from iFixit and that works fantastic. An absolutely precise fit, which is important especially when you might open your MacBook a couple of times during the years you own it. Not using the correct tool might do more harm to the screws than you want! I once had this with a Lenovo Yoga 3 Pro, which has Torx screws (T4 I think) and I used cheap Chinese quality tools, with the result that both the tool and one of the screws are damaged.

the macbook in the picture is 2012. does it has the same structure as 2013?

Edison - Reply

I never, ever, ever considered using anything but the correct tool on the Pentalobe screws. Too easy to strip and void your warranty (if still in effect), as well as make it almost impossible to get inside later for another upgrade or repair. The Wiha P5 Pentalobe screwdriver fits like a glove and costs only about $11 (a fraction of your drive's price)at Amazon.com. Get it!

There are two screws that are shorter-they go to the back near the vent.

I have a friends MacBook Pro that has some water damage that caused the MacBook not to be able to use battery power, but still work when plugged into A/C. Upon further inspection I can see visible corrosion on a few of the 9 cables going from the battery connector to that small circuit board. Is it possible to just replace that circuit board?

jramsey21 - Reply

I have the some problem. I was thinking to replace the whole battery but I am not it will solve the problem. Any suggestions?

salvatorebarbera -

Sometimes it can be enough to just clean the contacts without having to replace the entire board. Dosent work for complicated IC's like plcc type, where corrosion is underneath the chip. Here you will have to reheat and reapply the IC.

andrehedegaard -

Have either of you replaced the battery and/or circuit board to fix the MacBooks with the water damage ? I have the same problem with the MacBook working fine when connected to power but dying immediately when the power cord is removed.

Steve - Reply

Hi, Steve. I had the same problem: Macbook Pro 15 retina with coffee damage. And it worked fine when connected to power. I made it working after replacing the whole battery. It seems that circuit connected to the battery becomes disabled to prevent short circuit.

When placing the battery connector back into the socket on the logic board, check that every part of connector is pressed down. You should hear a soft click when it's back in place.

If you miss or let this step for later like I did, the power left in the battery even though the computer is completely shut down, will screw up the I/O board cable like I did. I noticed this after I put all the pieces back, turn the computer on and surprise, no wifi hardware is detected. -.-

I put a small piece of blue painters tape on the battery connector contacts to prevent it from accidentally making a connection and shorting. This helped keep things a bit more protected.

Same as my comment on Step 11: This step was not necessary for me to remove the battery. Perhaps it's a safety precaution? Regardless, I skipped the speaker cable removal (Steps 11, 12) and didn't have any problems replacing the battery. ( FYI - I used a heat path method, vs the solvent).

Overall, I really enjoyed this project and it was a complete success but this step is the one spot I came up short. I forgot to flip the retaining tab back down when I reassembled and I got a totally unresponsive keyboard and trackpad before I opened it back up and realized I had forgotten this tiny but crucial step.

  • 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.

is it possible to use MBP early 2015's battery on a late 2013 model?

Thanks to this guide I saved my broken MacBook Pro from a coffee spill that killed the battery. It cost me about 30% compared to what it would have cost to have the battery changed at an Apple authorized repair center. It wasn't easy to do, but that just made it all the more satisfying.

One comment: the new battery pack I bought came attached to a thin film which had to be removed. I unfortunately tore off some of the strips of glue attached to the back of the battery cells, before getting the hang of it. No big deal. But if you have to do the same thing: peel slowly.

After i replace the battery, the new battery is outofsync with osx battery indicator. When the indicator hit the 30% mark the macbook just shutdown completly. How do i syncroniz the new battery with osx?

The tutorial i saw only, tell you to fully charged the battery and let it depleet until the warning message pop up that your battery is low and your mac go into sleep mod. Problem my mac cant go into sleep mod because it thinks that it has 30% left of juice.

Is there any method to change the sleep setting or to force a recalibration?

I would download an application called coconut battery from here: http://www.coconut-flavour.com/coconutba...

This will indicate your battery's current health (I am not sure how accurate it is or how it measures the milliamps/hour) which might help you determine when you need to recharge it. I don't know what else you could do but I'd check the battery's health before anything since it might be causing the problem if it is faulty.

Brilliant guide, worked a treat.

Was tricky to remove the battery even with iOpener but carefully persevered. Took around 1hr 15 in total.

Thanks so much, this saved my girlfriend a lot of money!

Ben Saunders - Reply

How strong is the adhesive on the iFixit replacement battery, compared to the Apple OEM adhesive? Are we looking at a similar painful extraction process if/when we pull the replacement battery?

For that matter, is an Apple-esque strong adhesive actually necessary in this application? Double-sided tape is usually weaker; it might be a little thinner than the adhesive layer, and certainly far more user serviceable. Would tape be sufficient to hold the battery in place? Once you've got the bottom case screwed back on, the battery is immobilized anyway.

I really want to know the answer to this one

frugalpov -

It's still going to be fairly painful to remove. The battery needs to be very well secured—you don't want a soft-shell lithium ion battery coming loose and moving around inside the laptop. Even a little bit of movement could be dangerous.

Saved me fortune. I was using the laptop for more than year as a desktop. The new battery helped me bring the macbook back to life.
