Introduction

Use this guide to replace a worn-out battery.

  • Shut down and close your computer. Lay it on a soft surface top-side down.

  • Remove the following ten screws:

    • Two 8 mm 5-point Pentalobe screws

    • Eight 2.5 mm 5-point Pentalobe screws

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

When you say:

Remove the following ten screws:

Two 8 mm 5-point Pentalobe screws

Eight 2.5 mm 5-point Pentalobe screws

Do the 8mm & 2.5mm dimensions refer to the LENGTH of those screws, or the size of the pentalobe? That is, are there other sizes of pentalobe drivers like there are for hex, phillips and torx? When only one dimension is provided, it is usually the socket/driver size, not the screw length, maybe since the length cannot be seen when the screw is installed.

Can I suggest that you clarify your instructions so folks are confident they are only in need of _one_ pentalobe driver?

Nerdily yours,

The 8mm and 2.5mm are the length of the screws. One pentalobe P5 screwdriver suffices for all the screws (P5 is implicitly the size of the pentalobe screw heads).

I sourced all the parts from ifixit, plus a magnetic project mat which I found to be very useful for organising the teardown and reassembly.

Use the flat end of a spudger to pry both short sides of the battery connector upward to disconnect it from its socket on the logic board. Bend the battery cable slightly away from the logic board so the connector will not accidentally contact its socket.

I performed this on my MacBook Air (11-inch, Mid 2011), model A1370. Rather than using the spudger to un-attach the batter connector, I gripped either side with my fingers as the second photographs indicated, and gently pry/wiggled it up and out by initially pinching into the side gap with my finger nails. The reason I did it this way is that the spudger works by leverage and I was afraid to rest it against the components surrounding the connector. The photos and instructions are excellent and illustrate the maneuver perfectly.

Hello there... In my case by battery exploded.... Can I still try to change it using these instructions?

The instruction to lift the edges of battery connector before disconnecting is certainly not clear. In my case, the cconnector pins came off the board with the battery, requiring further costly repairs. I would suggest that this instruction be more specific and include a caution.

It worked fine for me, but as others mentioned, you need to be careful to remove the battery connector from the motherboard connector and not accidentally remove the motherboard connector from the motherboard itself.

Additionally, on reassembly, I found that quit a bit of pressure was needed to get the new battery's connector to snap in place. More than I was comfortable applying, but it was necessary and it worked without a problem.

    • Two 5.2 mm T5 Torx screws

    • One 6 mm T5 Torx screw

    • Two 2.6 mm T5 Torx screws

In my case the screw points connecting the old battery the case had fractured or broken. The broken bits needed to be cleaned out of the case before installing the replacement battery. Didn't want any loose fragments rattling about inside.

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

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

What if new battery comes with what looks like plastic around the 6 cells?

I'm having trouble reconnecting the pins to the new battery cable. Any suggestions?

Arrived with 52% charge, capacity 4593 mAh of 4680 mAh. 98% health, manufacture date of the iFixit replacement battery is Feb 4 2012 (2.9 years), with 0 charge cycles. My order arrived extremely fast, and replacing the battery itself was easier than expected. Overall speed of my MBA seems to have improved somewhat as well. Despite my MBA mid-11 being almost 3.5 years old, the internals, fan included, were all fairly free from dust. So far, so good.

I removed a battery pack from a mid-2011 MBA. Two of the lithium polymer cells had expanded so much that the upper case was bulging out about 0.5cm. The bulge un-bulged itself as soon as I loosened the screws on the lower case. There doesn't seem to be any significant damage to the hardware. Pretty wild. Also, despite this repair being listed as "Difficulty: Moderate", it's about the easiest thing you can do that involves opening the bottom cover.

THIS IS FANTASTIC!! I ordered it on a Thursday & received it on a Saturday! Came very protected in the box. It took me only 40 min to replace the battery & these instructions were excellent to follow! I highly recommend!

Very easy, and I normally have little patience for this sort of task. Took me about 20 minutes. Replacement battery was 90% charged and has 101% (!?) health.

I would like to agree: the difficulty is even less than easy

Very quick and easy to change the battery. Purchased the three tools needed from iFixit and they were perfect. The battery was 75% charged. I could not be happier!

Took me less than 10 minutes to complete. Computer rebooted as soon as put the MagSafe connector. I had to force a synchronization of the date/hour in Preferences to get it up-to-date (I guess the system would have done automatically a little bit later).

The battery came from iFixit. Battery stats, as shown by Battery health https://fiplab.com/apps/battery-health-f... show now:

Original max: 4680 mAh, Current Max: 4758mAh; Health: 102%, OS X Health Status: Good

The battery came is reported to be 3 years old(!) and came at about 80% charge

Instructions are very clear!

When installing the battery, the battery cable seemed a little long. It's not, but don't be too tentative about bending the cable so it goes down into the well. All considered the replacement went very smoothly and was done within about 15min. The instructions were very clear.

Après avoir commandé ma nouvelle batterie, et mon tournevis pentalobe T5 sur ce même site, j'ai changé ma batterie ce matin, en suivant ce tutoriel à la lettre et tout s'est bien déroulé. Merci pour tout . A bientôt. Rodolphe

I it took me less than 15 minutes to complete; the special tools and great instructions made changing my battery a snap; I did have to press one part of the battery plastic (near the fan) to get the battery to lay down flat, also I had to re-position / bend the connector cable to get it to line up and connect properly; it sure was a relief to see my laptop booted up with a 96% battery life .

There are adhesive transparent plastic covers over the 6 lithium polymer cells on the new battery. Are they supposed to be removed or are they there for protection?

Mike Heath - Reply

Response received from ifixit costumer support. Feel free to ask yourself though. "Those plastic tabs can be removed and it is recommended as leaving them on will make your battery slightly hotter. They do come off irregularly and may leave more or less residue but the aesthetics are not too important as it will be residing in your device."

How do I get the battery delivered to me in Nigeria? Can anybody help?

Akin Wande - Reply

Very easy, step by step directions. Thank you

I have been thinking about doing this repair myself for awhile now, and after I called my local Apple store and they told me that I can't even have them do it because they don't make/manufacture/sell this battery anymore, that decided for me. It arrived about 78% charged, and so far i have not noticed any problems with it. I didn't even need to use the guide because it was that simple to do.
