Introduction

Use this guide to replace a worn-out battery.

  • Before proceeding, power down your machine. Close the display and lay it on a soft surface top-side down.

  • Remove the following ten screws:

    • Two 9 mm P5 Pentalobe screws

    • Eight 2.6 mm P5 Pentalobe screws

  • The special screwdriver needed to remove the ten 5-point Pentalobe screws can be found here.

These pentalobe screw sizes can't possibly be right - not even close. Should they perhaps be 0,8 mm and 1,2 mm?

Rulle Boer - Reply

The screw sizes refer to the length of the shaft, not the diameter of the head or socket. P5 is the standard pentalobe size for all these screws, regardless of length.

I agree that the notation is a little confusing. I think it's because, with standard sized hardware like for your house, you have shaft diameter (say 1/8" or 3mm) and shaft length (say 3" or 7.5cm). So we're programmed to think of small numbers like that as diameter. But in this case, they're length.

Pulling the fan cable out was terrifying but you actually just pull on the cable itself. No way to get any leverage at the connector to dislodge it. Did come out easily but like I said, scared me!

Do you have good Test Point Voltages? It appears there are silver colored Test points on the I/O Board. I am working on a water spill and trying to troubleshoot if both the I/O board and the Logic need replaced.

It's probably not necessary but may be a little safer to completely discharge the old battery before replacing it.

Wedge your fingers between the display and the lower case and pull upward to pop the lower case off the Air.
  • Wedge your fingers between the display and the lower case and pull upward to pop the lower case off the Air.

  • Remove the lower case and set it aside.

There is a nub on the inside of the case which is attached to the battery. When you try to pull it open, it appears to be attached to the plastic casing of the battery, which sometimes splits. I gently unhooked the nub from the battery before removing the case fully. This seems to happen if the battery has suffered some drop damage (plastic parts broken around screws and parts of plastic frame split). Just an FYI in case your lower case doesn't pull away easily.

Grab the clear plastic pull tab attached to the battery connector and pull it toward the front edge of the Air to disconnect the battery from the logic board. Do not lift upward on the connector as you disconnect it.

The guide says: "Grab the clear plastic pull tab attached to the battery connector and pull it toward the front edge of the Air to disconnect the battery from the logic board", but the battery model that I was replacing did not have a clear plastic pull tab at all...

The battery model shown in this guide is: A1405

I was installing battery model: A1406

A1406 has the following connector:

Bottom:

By looking at the bottom of the new battery I saw how it could be removed. Simply by a gentle upward movement. I very, very carefully nudged it a bit upwards using a screwdriver on the left and right side, as shown here:

http://www.directupload.net/file/d/4122/...

It came out fairly easy, luckily!

(And yes, I also cleaned up this MacBook before closing it again. It was a bit hairy in a literal way. Electronics and pets is not the best combination. ;-) )

This was a great guide!

I think you may have been reading the wrong guide by mistake.

Looking at the various MacBook Air battery replacement guides, all of the 13" models show the connector depicted in this guide. All of the 11" models (e.g. MacBook Air 11" Mid 2012 Battery Replacement) show a connector like the one in your photos.

The 13 inch's tab is a bit more difficult to reinstall than uninstall. Delicate care is needed.

Andrew Ruble - Reply

This is the tricky part if there is one. Just pull back towards the battery and not up.

When handling the battery, avoid squeezing or touching the four exposed lithium polymer cells.

  • Lift the battery from its edge nearest the logic board and remove it from the upper case.

Quick note about the replacement battery, if you bought from iFixit and the battery sections have a thin film over them, peel them off. They're to protect the battery during transit, and if you leave them on they might cause heating issues.

Here is a link to my question about it: Replacement battery has thin film on each section do I need to remove? plus, I just got an email from iFixit customer support that it needs to be removed.

My Mid 2012 doesn't have any plastic on the battery connector. Near to impossible to remove it.

Mine did. ¯\_(ツ)_/¯

Worked flawlessly on my MBA. Installed in 5 minutes. Coconut Battery now reports 6801 mAh on a design capacity of 6700 mah. That's an improvement as my old battery was clocking a meager 61% of design capacity (i.e., 4087) after 371 cycles.

Easy. Perfect replacement.

I tried to opened it and I failed. The screw doesn't work well. Worst idea ever!

Very easy. I bought the "A-Stock" battery. It came at a max charge of 6300mAh (max of 6700) -- decent. But within 2 weeks dropped down to a max of around 4,000 mAh. I'm thinking that I should have spent the extra $10 and bought the new battery. (I am using the Coconut Battery App.)

gvr4 - Reply

Update -- after about a month with the A-Stock battery, I got the "Service Battery" warning, but it did not stay -- disappeared after a while. Strange behavior. I would not recommend buying anything but a new battery based on this experience.

I'm wondering if you may be seeing a calibration issue. Batteries in Apple products can (generally) be recalibrated by draining them as much as possible (e.g. start playing a video or doing something else that will draw a lot of power and prevent it from going to sleep, letting it run until the OS does a battery-empty shutdown) then charge it to 100% without using the computer (e.g. leave the lid closed and the charger attached until the charger's light changes from orange to green.) Maybe repeat the cycle one or two times if you think it will help (although it should only be necessary to do this once.)

It wouldn't surprise me if a new battery needs recalibration after installation.

Guide was perfect. Saw several other guides mention T5 screws for back cover. This guide was correct with the 5-point Pentalobes. Got the iFixIt 54-bit driver set. Worked perfectly. Bit disappointed that CoconutBattery reports the battery is capable of 98% charge (6583/6700mAh) but I can live with that vs. the 48% on old battery. Thanks for the guide and parts.

The guide was great, the supplied screwdrivers worked, everything was where it was supposed to be (e.g. the plastic handle on the battery connector) - I was done in 10 minutes. Everything as advertised.

My batter was new, 6812 mAh.

Straightforward guide, completed in about 20 mins. The new battery reports 6746 mAh. Many thanks.

Be gentle when screwing in the replacement battery!!

I used little force but the corner plastic snapped and cracked...

Dennis - Reply

The screws have been treated with thread-locking compound. The exterior, case screws have been treated with particularly tenacious compound, which means it will take markedly more torque to unscrew them than the proper torque for screwing them in. When loosening and tightening the case screws be sure to have the driver well seated and aligned perpendicular to the head in both planes or you may bung up the heads.

For both interior (battery) screws and exterior (case) screws, don't assume that how hard you needed to twist to loosen them is how hard you should tighten them.

Installation was a breeze but now my battery % is on 87% for 4+ hours (where it was on the old battery) and when I unplug MagSafe power shuts off immediately. Any help appreciated.

Jeffmorris, try getting coconut battery and looking at the health of the battery, if its not the battery could be a larger issue. Sorry!

I replaced my wife's battery with this guide and it was a breeze, it's taking forever to charge though, maybe it's balance charging?

Thank you so much for the guide, super easy diy. getting the right screwdriver was quite an adventure but the repair took less than 10 minutes. If the battery works as advertised I will have an almost new macbook to work with.

thanks again.

Hello! I did this for my MacBook Air 13" mid 2012 and everything's fine. I'm charging it right know to the fullest. It's my first time that I open a MacBook and this guide worked perfect for it. I hope it keeps this way. Greetings from Mexico and keep the awesome work!

I have successfully replaced my MBA Mid2012 battery.

The instructions worked like charm... Kudos.....

Keep up the good work and much appreciated.

I ordered the battery from Amazon :-http://www.amazon.com/gp/product/B012BZM...

I had dropped my Mac Air on a tile floor and it would only boot up when plugged in. If the magnetic connector was jiggled the computer would shut down. Not fun! I taped the connector to the computer but even so, it would easily shut down unless handled like a case of eggs. Bought the pentalobe screwdriver from Ifixit. Had the back off in a flash. Gave the plastic tab on the battery connector a little push. Felt it click back into place. Replaced the back. Battery now working again. Thanks! Saved a trip to the Apple Store and probably a lot of cash.

Worked flawlessly on a Mid-2012 MBA -- my old battery was almost completely bailed out, followed this guide with a new battery and the P5 + T5 screwdrivers (both ordered from here) and had everything up and running in under 15 minutes. Much obliged!

As easy as pie, now my wife Macbook Air have new battery with cycle = 0 :).

Sang Le - Reply

Cheers to those who put this tutorial up. Followed the steps, worked perfectly!

Point to note:

The very end of these pentalobe screwdrivers can be very thin and sometimes a weak/cheap metal is used to make them.

IF you're pentalobe screwdriver "strips" at the head (NOT the screw itself) as you're taking out the screws, don't worry, give the very tip (straight-on mind-you) a quick pass in front of a grinder or hasp to in order to remove the rounded off edges and make it flat again!

Worked like a charm for me.

Again thanks for the advice!

Guide worked great! I bought an Anker battery off Amazon. I've had good luck with Anker external batteries. It cost more than some of the other brands but still 2/3 of what Apple would charge. The battery came with two sets of tools: the Torx and Pentalobe drivers. Was surprised at how tiny the screws were but the tools are magnetic and the screws stuck well to them.

The guide worked perfectly for me. The plastic tab broke off of the new battery but I'll cross that bridge when I come to it. The entire operation took about 15 - 20 minutes. Thanks!!

Perfect guide. Bought the part from iFixit and installed in under 5 minutes. Well worth the effort.

After any hardware installation, even minor ones like this, its worth running the Apple Hardware Test to ensure you didn't forget anything or nothing is misbehaving. While booting, hold down the D key and follow the prompts. Good 5 minutes to check everything is ok.

Ben - Reply

Easy-peasy. If you have the 2 tools/drivers and the battery you should be able to complete the replacement in less than 30 minutes (without any prior experience).

You may have to reset the date and time on your laptop afterwards, you'll know when you cannot access Google and other servers because your clock time/date is way different from the server time.

Great job.

Excellent guide that was easy to follow and left no unwanted surprises. Never opened a MacBook air (A1466) before so all new to me and had no trouble at all. I bought a new Hasess A1405 battery (https://www.amazon.co.uk/gp/product/B016...) which came with the necessary screwdrivers that worked fine. They were magnetised, as mentioned by another commenter, which was really handy as the screws are very small. The battery was sold as a 6800mAh/50Wh but the system information (Power) was showing it as 7188mAh which was a very pleasant surprise. Mine is a mid 2012 MBA and has the plastic tab on the old battery (and new battery) so pulling out horizontally, not vertically, worked like a treat. Interestingly, in response to comments about battery holes not lining up or breaking, my apple battery had broken 2 clips which left bits of plastic in the case that I needed to pick out before fitting the new battery. It didn't cause a problem to the operation of my MBA. Thanks!

While reversing the guide and installing the battery the plastic connector was frustratingly hard to connect to the logic board, but the guide is good in itself. It took me about 25-30 minutes, but I am finicky and overly careful. If your laptop is especially old, I would suggest having a can of air on hand.

My battery gave a failed signal for a while, and then it began working again. This happened after the first cycle. MagSafe2 stayed completely green--rather than going to amber; a reboot and replug caused it to fix itself -- it will probably happen again, unfortunately...

Andrew Ruble - Reply

Great guide. Should be rated "easy". With only 15 screws and a connector, no adhesives, no flex cables or flimsy clips, this battery is basically user-replaceable.

Hey, I just finished changing my MacBook Air 13" mid 2012 battery myself and it was a piece of vegan cake. This helped a lot. I had no problems with the manual/guide. I just had some screws issues like the screws were worned out. Overall, these steps were easy to follow. I hear that batteries that are not original would kill the mother board or another part in about 2 months so I hope not. I will try to check back on this thread later to keep y'all posted. Today is 07/25/17, I would like to post another note on 09/26/17 and say it still works. I saved money and would recommend doing things yourself if possible. Again, thank you.
