Sir, I can't thank you enough for this very clear walk-through of the process from end to end. I took my MacBook Pro 15, Late 2013 in to the Apple store in late December 2022 and was prepared to pay them $200 to replace the battery. The machine was crashing frequently and when I took it off the charger, the battery level would go from 100% to 70% in about 5 minutes and then crash. Apple told me that the machine is so old, they don't offer replacement batteries anymore. I was going to take it to a 3rd party fixit place (GoEBITS) but then I came across your video. (Isn't KZfaq the most wonderful thing?!) I took your advice and bought the battery kit from IFIXIT for $90. I noticed they also offered replacement plastic feet, so I bought a set of those too (3 of mine had fallen off). It took me about 90 minutes total to replace the battery and the feet and now my computer has a new lease on life! (And I feel so accomplished -- I'm a computer repairman!) Thank you, thank you, thank you!

Thanks for the video, will be replacing mine this weekend! For everyone watching don't remove the tape on top from the new battery until after you glue it and line it up! makes the process easier to line up the new battery.

Perfect guide, thanks for taking the time to put it together. Getting the adhesive off of the frame is the most time consuming part

Worked like a charm. I didn't even need the string since I was able to gently pry them up with some plastic sticks. YMMV. Thanks for saving me a ton of time!

I watched several videos on this and yours was by far the most helpful. Thank you so much for making this. When I took the case off, there was a lot of dust in the computer. I used compressed air to carefully clean all of that out. Got the battery and kit from iFixit. Used a guitar string and a pair of gloves, which made the battery removal pretty simple (still used the chemicals that came with the kit). Got the whole job done in 40 minutes. Mac is now back up and running and in excellent condition. Saved a lot of money and multiple days of down time from what Apple quoted me and learned a lot in the process. Thank you!!

Perfection! Thanks for such a thorough and well filmed tutorial! I followed exactly and easily and now have a wonderfully working macbook and trackpad once again!

Great idea using the nylon thread/string, it worked like a charm and installation was a breeze. Keep posting more videos like this.

Your clear and uncomplicated instructions worked perfectly for me. Thank you, Puromac!

Just wanted to say thank you for posting this guide - it prompted me to take on my early 2013 MacBook Pro whose battery was on its last legs. I ordered the kit from the European iFixit store (big up to them for delivering in two days to the UK from Germany - great service). The kit was fantastic and literally has everything you need. The only hiccup I had was that there is a base plate (shown in your video) which protects the touchpad and I accidentally removed mine as my nylon string went behind that instead of the battery. Absolutely no biggie as it stuck back down nicely and the job is done - took around an hour of careful labour using your string/twine method. Thanks once again.

Excellent video! I just completed the change out of my old swollen battery on my 2013 Macbook. It now sits flat again and my track pad works. Very pleased and thank you for eliminating all those unnecessary steps. Very thankful for your video!!!!!

I used this tutorial for my MBP 15" early 2013 model, and it worked great! In addition to improving my battery life, my laptop also runs much cooler than when my old battery had a "service battery" warning. I use the Mac Fan Control app, and I was clocking CPU core temps of 85-90C while using Google Chrome prior to this repair, and up to 100C for Adobe design programs! Now, the CPU cores run at about 45-55C for Google Chrome usage, and about 70C for Adobe programs... About the tutorial, I will say that the adhesive was much, much harder to dissolve than this video advertises. It took hours of applying solvent and sawing/prying under the battery in cycles. **Be super careful not to bend or warp the battery, it can catch fire or explode** Also, the trackpad is directly underneath the two main battery packs towards the center of the laptop. I almost dislodged the trackpad from the laptop when attempting to pry the battery from the adhesive. Make sure to wipe any excess fluid or remaining adhesive from the edges as well. Luckily, it still functions just fine, although it doesn't press down as far as it used to. Another note, the battery from IFixit did not sit perfectly flush some reason. Make sure to connect the battery to the laptop before you remove the protective plastic coating from the new battery & stick it into place (if you run into the same problem). There is a bit of flexibility in the wires that run from the battery pack to the connector. Lastly, make sure to dispose of your old battery using a hazardous waste removal company. It is unsafe to throw it in with standard trash.

Thanks for this great video. I held off for more than a year on replacing my battery after looking at the enormously complicated ifixit guide but with this video it was all over in less than an hour and I didn't even need glue remover (I used nylon string).

Just used your method and it saved me a bunch of time. I ordered the same kit you used from ifixit, and I was able to change the battery and now all is working well. Thanks so much dude, your video was SUPER helpful!

Thank you for this! Btw, dousing the string with the adhesive remover helped immensely.

Thank you, thank you, thank you! I’ve been putting off replacing the batteries in two of my MacBooks for ages. After watching your video, I’m far more comfortable attempting it with using your technique than others I’ve seen.

Thank you so much for this tutorial! I was hesitant to take my laptop somewhere in fear of someone else potentially doing more harm than good. Your instructions were VERY helpful and I was able to replace my battery with no problems! Appreciate this!! 🙏🏽

Awesome! I used this video to successfully replace the same iFixit battery in my MBP late 2013 15". The battery was still holding a charge but had expanded so much it would not sit flat and the trackpad was unusable. Now it works great. Using the kit plus the idea of the string was brilliant. This video is how "how to" videos should be made. Thank you for sharing!

Great tutorial. Just replaced my battery following it (no issues at all), the string technique is what made it a lot easier, just have to be patient for the adhesive remover to do its work.

Really good steps to do. I didn’t have the adhesive remove (which would have been easier) but I still managed to do it with the nylon thread but needed gloves as it was harder work to get the old battery out. Make sure you have the right screwdrivers as well. Great guide...thanks a lot

Best one I’ve seen yet!! Ordered my Ifixit kit , I have same model! Great job

Good tutorial. One of my only extra bits of advice would be to not squirt the adhesive remover directly onto the plate covering the trackpad (squirt it onto the cloth instead), since some of it might leak around the edges of the plate and get to the workings inside the trackpad, where it might do some damage if there are any parts that are sensitive to acetone. Even if the acetone doesn't damage the trackpad, it could continue flowing downward until it leaks past the edges of the trackpad itself and drip onto the display, which of course has a clear plastic front, where acetone could indeed do some damage. Just to be certain, it's a good idea, before you start applying the adhesive remover, to insert something impervious to acetone and other fluids between the display and the keyboard/palmrest/trackpad, like maybe a sheet of aluminum foil.

TY. I watched this vid a month ago and it gave me confidence to order & attempt. I never would have for something with 50+ steps. I just got the battery today, watched it again, and successfully removed & replaced the battery. Thanks again.

Just changed my wife's MacBook Pro battery using your tutorial. Excellent work. The hardest parts: getting the adhesive off (ended up using a razor blade, very carefully) and aligning the two battery screws on either side of the connector (I didn't, and didn't put them back. The laptop is pretty much a desktop and won't be jostled too much, so I'm hoping that won't be an issue. Besides, the battery is solidly stuck in place now and won't move.) Kudos to iFixit for their excellent kit. I love that it came with all the tools.

Thank you! I followed this video and was able to change the batteries. I bought the batteries from iFixit. This is really good video! I found using thread more difficult than what is being shown on the video. The last part of cleaning up was a bit tedious and I had to use scrapper to clean it up. Overall very helpful video! Thanks again!

Thanks for the tutorial. Followed it for replacing the battery in my Macbook pro and went pretty well although took quite some time as the middle two batteries really seemed quite stuck. You just saved me £120

Great guide, thanks. I also ordered the iFixit kit and followed a similar technique to yours but used dental floss and no adhesive remover. My kit did not have a syringe but a bottle with a tapered tip which made it difficult to apply in the way you did, but using a sawing action the battery cells came out without too much trouble.

Just replaced it according to you advice! It is now the second time, since I got my MacBook in Feb 2013, that my batteries were bloating to an extend, where the trackpad wouldn’t work properly anymore. The first repair was within my Apple Protection plan and the repair was claimed to have normally cost me 980$ , so I was glad I had the protection plan. This second repair was done by myself. Spent 59€ ( about 67$) for the battery pack and less than 30 minutes following your advice. I was initially shocked when I reviewed the iFixit procedure on their website/ repair manual, since it was marked as very difficult, was long ( 50+ steps!!)and with its own adherent danger ( just for the sake of preventing solvent damage. ) My extremely bloated old batteries turned out to be removed with surprising ease , utilizing a bit dental floss and a plastic spur. Thx again for your fantastic video!👍

Thanks so much for this video! First repair I ever did, and this video on the background helped me through. For anyone else trying this in the future: I found the dispenser of the adhesive remover a bit unpredictable. So I just used a double thread of dental floss, and with the sawing movement I did not have to use any iFixit adhesive remover to remove the batteries.

Thanks for the brilliant string technique! Worked like a charm.

Thank you for uploading and sharing. Because of you I attempted and successfully removed the old bloated battery. I will try and upload a reply video for others to reference (I’m not really a youtube content creator, so that might never happen). My battery was a fair bit more swollen but it all worked out. In Canada, ifixit does not provide the adhesive remover. I suspect they can’t import it and nothing local exists. The sawing nylon string method worked without any use of adhesive remover. I will say it wasn’t as smooth a process, but I was able to safely remove it with minimal off-gasing. Thanks again!

Fed, thanks so much for this tutorial. I completely agree there is more risk to taking out all the internal components as recommended by iFixit so I was very pleased to see, and then use, your approach. I used isopropyl alcohol to dissolve the glue, which I'm fairly sure was not nearly as effective as using the adhesive solvent, so the process took a bit longer and was more tedious than I'd hoped. But nonetheless all went well and I have a new battery in my 2012 Macbook Pro, giving it another few years at least. Thanks again Fed and @puromac!

Stucked at zif connector in iFixit guide and switched to this video. Far more easier. Thank you very much.

Excellent instructions. I used nail polish remover and gift wrap curling ribbon and used gloves to exercise additional force on the ribbon without hurting my hand. Worked perfectly. Thanks.

Wow what can I say but the best video on the web for changing the battery on my laptop. I previously watched a video taking all the parts out of the computer before replacing the battery . Glad I found you Best Regards Allan

Wow. I can't believe I find this video from a super old friend! Yes, I'm replacing the battery on my MacBook Pro... Thanks! Miss you buddy! Cheers Fed!

Fantastic video. Totally worth watching this and skipping the more complicated steps. I regretted not buying the ifixit battery but already bought a replacement kit without the tools or adhesive remover. For those in my shoes, you can use Goo Gone instead of the ifixit remover. It is non-toxic as well and worked great. It is a little nerve wracking at first to use the string method, but it works great. Thank you

Just finished my replacement based on this video. Excellent technique - the "string cutting" worked really well for me. An additional note for this technique: you may hear a little "popping" that sounds like it could be battery cracking - in my case that was the sound of the little piece of metal below the center batteries flexing as I "cut" the batteries off it. Once you know what that is, it's pretty obvious - but the first time it can make you worried that the batteries "cracked" (which, of course, no one wants...)

I've seen several variations on how to do this and yours is the best version. Thank you! Now I can fix my girlfriend's computer and save her some cash.

This is SUPER it gave the confidence to go out and do it my self

Fantastic. so much easier and intuitive than the other videos removing all of the extraneous components.

Great video. Thank you. I purchased the iFixit kit as well. I used 80 lb test braided fishing line instead of string and I did not need to use the solvent to remove the batteries.

Just did this, and it works. Thank you for showing me how. One thing that is different - the iFixit kit now includes a squeeze bottle with a tip rather than a small jar of solvent and a syringe. Much harder to control where/how much solvent is applied. The center 2 batteries were much harder to free up, perhaps because I was too concerned about getting solvent on the trackpad, which was underneath. But it worked!

Thank you very much ! I sent my MacBookPro to Apple who told me after 2 days, sorry we can't repair it, it's too old ... I saw your video, ordered the ifixit kit and followed the steps you show on the video ... everything is working fine even the trackpad is working again... thank you very very much !

Great video - probably the best one out there for Macbook Pro battery replacement technique.

Thank you...I quite enjoyed your method/explanation on this! I'm getting some kind of overheating issue, or it feels hot on my lap these days, but there is really no battery swelling to date, so I'll have to check to make sure my fans are operational! I'd not heard of Ifixit, so I'll definitely look into this! I did upgrade my SSD drive via 'Macsales' using the Aura 1 TB SSD two years ago, and it's worked flawlessly, and my previous 512 SSD is now an external drive! I love being able to DIY and will again watch this video prior to changing my battery when the time comes! Appreciate you doing this video for us!

The "sawing with string" method seems like the best way to remove the batteries without using excessive force.... nice instructional video!!! Thanks for sharing!!!!! Ifixit will get another customer now!!!!

Thanks for the video! The procedure worked as explained. I used waxed dental floss to saw through the stickers and used the plastic tools to remove the batteries toward the front of the case while using the cards to leverage the batteries.

Thanks very much. Watched a few videos and they made it overly complicated. Followed you step by step and now my laptop is working like new again!

Thanks for the video. I was able to replace my battery with your video instead of taking the entire macbook pro apart, like some other videos.

Thanks for your review and instructions. I followed your steps and it worked perfect. Over all very easy and saved my computer for 100 bucks.

Mate, you just saved me some cash, because I was so scared with OWC Battery Replace video and also IFixIt step by step that I was about to pay a technician to do this for me. None of the other methods are as easy as your "nylon and string" method. Thumbs up! But just a heads up: I wasn't that careful on avoiding the (OWC) Newertech adhesive remover touching the plastic base of the speaker that lays right in front the border cells. Just a little drop of it touched the black plastic and it turned white, as some chemical reaction was happening and melting the plastic. So people, while applying the adhesive remover be extremely careful to avoid dropping a bit of it on the logic board or touching any piece that is not supposed to. Again, thanks heaps for your video!!

Used this and worked great; placing the MB on a little angle and using the cord are neat tricks!

Thanks! This helped me. I did it without the iFixit kit so I peeled the batteries myself - and it turned out ok as well.

I think you have the most accurate video about this subject. Thank you

Thank you for your video, the twine technique worked amazing. Watched your video and had the battery out and new one in within an hour.

Awesome video! Expecting the new battery today and will follow these instructions to install. Thanks for posting!

By far the best video on this subject.

I wish you made this look a little harder to do. I feel like my odds of blowing myself up just seriously increased.

Amazing tutorial and so easy. I had to swap batteries today in a pinch and this video helped me greatly

I was not sure if there was a cover protecting the track pad, looks like there is ! Thanks, great video.

This is the best solution I have seen. Thanks so much. I should also say that the battery you get from iFixit is far superior to the $25 batteries you can buy on eBay. IFixit provides an incredible service and is worth paying a little extra for.

I did this job on my son's Late 2013 this morning. I found that using an old credit card from the side worked nicely to loosen the batteries. $55 for an OEM battery off Ebay. Came with the tools for the case screws and the battery screws, too.

Thanks so much! was a life saver going this method rather than ifixit's 54 step horror ! :D

nice work! good idea on using the string to cut through the adhesive.

Thanks - This video is exactly the way to do this. I just did this today, using the same ifixit kit and it worked perfectly. My original battery was ballooning badly and it had only 77 cycles. The only issue I had was startup after replacement. I got errors saying can't load system software and then no system found. I reset the SMC and the Pram, after which it booted up fine.

I used the iFixit kit and instructions. Worked like a charm.

Thanks so much, worked great. I didn't have that kind of adhesive remover, what I ended up doing is dabbing some Goo Gone on the string, adding a little more as I worked down each battery, worked beautifully. Thanks!

Thank you so very much for this - the BEST video I could find on replacing my MacBook Pro battery.

Thanks for the video "hand holding," it made all the difference. May I add a couple thoughts? Applying the solvent: when I tried squirting it gently into the gaps, the fluid wanted to get sucked uphill instead of flowing downward (capillary action, I think). I could dribble it in, and it would disappear uphill. Not what I wanted. I got around it using one of the guitar-pick looking tools they sent. I stuck the little flat tool into the crack, and when I dribbled the fluid down the pick, and it flowed behind the battery like I wanted. Also, it was hard to keep the fluid from seeming to want to flow into the top of the trackpad for the center two battery packs. I didn't hear you address that, and when you did it, you seemed to just squirt the fluid in at the top. It didn't seem to cause any lingering problems, so far, but it did concern me. In your video (13:16) you can see clearly the trackpad butts up against the case, so there's a gap for fluid to go into. And my fluid bottle had a built in nozzle, not a syringe, so it was not as easy to manipulate. I guess they've changed components since you filmed this.

I used a composite shim (available at any hardware store) to remove the battery and the adhesive stickers plus used some nail polish remover.

You saved me so much time, much easier than the iFixit method!

VERY clear and concise instructions. Will attempt to change my battery myself vs taking it to a repair shop.

Thanks! Just swapped out my 9 year old battery, made a huge difference!

Thank you for the Tutorial! Just replaced my battery, not too thought, but not super easy… just little patience. Thanks for suggesting ifixit too.

This video saved us a lot of money. Good job, thank you very much!

Thank you very much for the video. Of course, with the right tools it is always safer and easier, but I did not have time to wait for them, and managed to do it also with a dental floss, an old credit-card-like thing, and without the glue solvent.

now that its been a few years, how is the battery holding up? I am at the point in my macbook that the battery is lasting about 2 hours with basic use. The health of the pack is at 80%. It is not swollen. I'm currently on the fence whether i should replace it already or wait until it gives me less use on a full charge. Thx!

Thank you for this! I just finished replacing my battery. I’m now doing the calibration procedure. This was easy, peasy with the help of your vid. The batteries came out easily. Just want to remind folks: don’t forget to drain your battery and to protect the display with aluminum foil.

You da man - great video - just what I needed to prepare - ordered my parts and now awaiting - had also seen ifixit guides but, your video looks sure to help. I didnt get kit but, got own acetone and air can duster, prods, screwdrivers, Q-tips etc. all for less... hoping all goes well - mine a swollen like little pillows and kinda worried about exploding etc....

Thanks a million. The string tip for removing the old battery was great. I actually used 80lb fishing braid line and no glue solvent. Had to wear gloves so the line would not cut my skin, but it worked perfectly. Now I can carry my MacBook again without the need of being plugged.

Excellent demo. It worked like a champ.

This is much quicker than removing all the components and the nylon string idea looks easier than using the plastic credit cards supplied by iFixit. I went the other route and removed all the non-battery parts first. I found a lot of dust inside the heat pipe vents and the fan vanes. So this allowed me to use a soft artist's brush and vacuum to clean the dust off all the parts. I agree there's more risk of damaging the very small connectors and you have to be careful when reinstalling the logic board not to trap the various cable ends around it. Removing the dust allows my MBP to run cooler and quieter now with the new battery. Thanks for the good tips.

the best tutorial ever and approach for this task. Thanks!!

This method worked like a charm! One video showed basically disassembling every component from the case prior to battery removal. That was too many screws and connectors to remove and reassemble. One slip and the MacBook was dead! Tilting the case to keep the acetone under the batteries, and using great care with the string negated the laborious disassembly. The residual tape in my MacBook was much more difficult to remove than yours.

Excellent instructions. I just changed my battery out and it was so much easier than I was expecting. I used the iFixIt kit and it seems to be operating very well.

Thanks for posting this. Not having adhesive remover and the wires handy, I use WD-40 and dental floss instead. The dental floss is not as strong so it breaks easily, but I manage to do it eventually after several attempts. It takes me 2+ hours.

This was INSANELY helpful! Thank you for taking the time to create this video.

Great guidance - Made the job that much easier. Thanks!

you saved me so much freaking time and pain. Thank you.

THANKS so much. Mission accomplished this evening. I had my steel trash can at the ready in case of battery fire (as were quite swollen). TIP: blow the dust off your fans while the cover is off - just a can of compressed air for this.

I must say thank you for this is saved me a headache. It was a pain in the butt to get all the sticky residue off but I did and got it done and now my busted battery is at 107% of new. I fixit needs to change up their site or at least link to this video.

Didn’t follow exactly but this video was excellent! I just fixed my battery in my laptop so thank you!

Very nice video. Everything went just as you described.

This was great. Thanks

Thank you man, I’ve done it quite easily by your guidance

Thanks for the video. Your instructions worked perfectly.

Yeah thanks! I had to buy the battery from another dealer (iFixIt wouldn't send to Hawaii). Glad I read the video because I probably would've tried prying out the battery and it exploded or something. Replacing the battery on my wife's iPhone 7 was one of the scariest things I've done lately... iFixIt is willing to send me adhesive remover :)

Worked like a charm. Great tutorial! Big hugs.

many thx. just finished according to your manual and it works!

Excellent walkthrough! Thanks
