Introduction

The battery is made up of six distinct cells, four of which are adhered to the upper case. Use great care in prying these four cells up from the case—bending or puncturing them can damage their performance, and may release hazardous chemicals. Only use plastic tools when prying.

    • Removing this board will ensure that the battery remains disconnected throughout your repair, preventing your computer from accidentally powering on. It's also a good idea to take it out so it doesn't fall out unexpectedly.

WHy to remove battery contact board? Replace can happen without it also, right.

This is the most difficult step. The tip of my spudger got bended and the aluminum case damaged it.

Hi where can u buy the battery for these

Kevin Higgins - Reply

Did you find out where to buy?

Uli -

There is a much easier way to get the batteries out. If you look at the 2 cells on either side (left and right), you will notice that they put them in an area that is slightly lowered. This is by design. To remove the batteries, pour a small amount of 90% isopropyl alcohol on both sides and let it sit for about 30 to 45 mins. It will dissolve the glue and you can gently then lift out the batteries without any prying. After you remove the batteries, simply wipe up any remaining alcohol, let it dry, buff it clean, and insert the new battery. Considerably easier and safer than potentially damaging the battery packs. If you are putting the same battery pack back, just use double sided tape. IMPORTANT NOTE: ALWAYS BE SAFE USING ISOPROPYL ALCOHOL AROUND FLAMES OR ANYTHING THAT MIGHT MAKE IT BURN. ALSO, NEVER ATTEMPT TO PRY THE BATTERIES IN ANY WAY IF ANY ALCOHOL IS STILL POTENTIALLY PRESENT!! WAIT UNTIL IT IS EVAPORATED!!

Thank You for the hint with the alcohol, but where can I buy a spare battery?

Uli -

looks like they run for $100 on ebay

bluto20 - Reply

They are on amazon for around $60-$70.

Prying the battery out is HARD! and VERY dangerous. I tried using a flat head screwdriver, put it under the battery and twisting the thing out. DO NOT DO THAT!! as it can punch a hole in the battery if you twist it too hard. I had a small smoke coming off by doing that and was lucky enough it didn't burn. Using isopropyl would be an ideal solution. But to bad I can't find that around here :(.

[DO THIS ON YOUR OWN RISK] What I ended up doing is using the screwdriver to gouge the underlying glue out as much as I can on the side (about 10%) and use fingers to pry it up. Good luck!

Perfect! not as difficult as it looked first, especially with the proper tools. To take the batteries out the alcohol (I used ethanol used for cleaning purposes) works like charm. I put a few ml in nearby the batteries, waited maybe 20min and was able to pry them out easily. Tried before without the alocohol and nothing moved. I ordered the battery on ebay for 70€ and it has the same numbers and text as the original it says apple japan as well. My old battery had more than a thousand cycles after 3 years and did not last vey long. Now the software shows 0 cycles and it is charging starting at 15% and will be fully charged in 2:45h. I think apple charges 249€ for the job here in Gernany. It took me about 1 hour to replace it (with waiting).

How much ethanol was necessary to remove the battery? Did you use a spudger or similar to pry it out? I just put about 3 ml of Isopropanol nearby the battery and waited for about 30 minutes. Unfortunately I couldn't remove it though. It still was firmly glued.

Thanks for the excellent instructions. They were easy to follow and the new battery is working. I purchased my battery on Amazon from Brtong for $49.99. I just installed it so I don't know how long it will last but it was new and the cheapest price. It came with two tools to remove all the screws.

This is a great resource. Thanks to all that contributed to this. I was able to replace my battery today and all went well. I had a very hard time removing the old battery. The spudger broke on me and I was afraid to use alcohol so I used a screw driver and sure enough, sparks flew removing the old battery. But got it done.

Thanks again to all and ifixit.com

Thanks for the guide! Perfectly presented. Took me about an hour following the steps.

t's very important to keep organized during this replacement for ease of reassembly as there may be different size/length screws in the same step.

Someone else had mentioned using isopropyl alcohol to remove the adhesive from the batteries which is truly a great idea.

In my specific case, isopropyl alcohol was not something I had on hand. As a substitute, I used my wife's nail polish remover since Acetone evaporates fairly well (yay high school science class FTW) and sure enough, they came loose no problem. This method is NOT guaranteed, but to the careful DIYer can work great in a pinch.

Daniel Conley - Reply

Followed this point to point description and it worked like a charm (Isopropyl alcohol also helped)! (Isopropyl alcohol is sold under different brand names.)

Screws described in points 15 and 19 are not exactly as my MacBook. You describe 2 long and 1 short. I have 1 short black screw and 2 long screws (1 black and 1 silver) - the silver one in the corner and is hidden and covered by "metal wool" (peel it of).

Sadly this was a disaster for me.

All went well at first. I was able to follow all the instructions, and I used some alcohol, since the batteries were very hard to remove. Make sure the force you apply is aimed downward, to scrape through into the adhesive. And don't use much. When the battery is ready to come up free, it will. Don't rush it and pry upward until it's really starting to lift, meaning the glue is giving way.

The rest of the instructions are easy, so I thought. I actually managed to break the left speaker connector from the board. I wasn't too worried, as I don't use the computer speakers much anyway. On reassembly, I tried to glue the connector back. Doubt that worked.

I was able to reassemble the whole machine. When I powered it on (with cable), the battery was recognized (system report) but WOULD NOT charge. The system then started to degrade. Mouse and keyboard started malfunctioning. It's dead. Will return the battery, and go shopping.

Just performed this today suing the same brtong battery from Amazon that someone else mentioned. $50 on Amazon. The instructions were perfect. All worked like a charm. I was scared off at first due to the stated difficulty. It is possible the glue on mine wasnt very good maybe. But seriously, anyone considering doing this, do it. It is not hard. And well worth it.
