    • Pull off the black rubber stopper from your bottle of adhesive remover.

    • Twist to loosen or remove the bottle cap before you cut the applicator tip.

    • This unseals the bottle and allows the pressure to equalize before you cut the applicator tip. If you skip this step, the adhesive remover may spray out unexpectedly when the tip is cut.

    • Use scissors to cut off the sealed tip of the applicator.

    • Cutting close to the narrow tip will give you better control so you can apply the adhesive remover in small amounts.

    • Twist and close the bottle cap securely before you proceed further.

  27. MacBook Pro 13" Retina Display Late 2012 Battery Replacement: passo 27, imagem 1 %32

    • Lift the battery as a whole up out of the upper case, and remove the battery.

    • Before installing a new battery, remove all the old adhesive from the MacBook Pro's case.

    • With a little luck, you can slowly pull out each strip of adhesive with your fingers.

    • Otherwise, soak each section of adhesive with a bit of adhesive remover for 2-3 minutes, and then scrape it out with an opening pick or one of the other tools in your kit. This can take quite a bit of work, so be patient.

    • Mop up any remaining adhesive remover and give your MacBook Pro a few minutes to air dry.

    • 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 newly installed battery: charge it to 100%, and keep charging it for at least 2 more hours. Unplug and use it normally to drain the battery. When you see the low battery warning, save your work, and keep your laptop on until it goes to sleep due to low battery. Wait at least 5 hours, then charge your laptop uninterrupted to 100%.

    • If you notice any unusual behavior or problems after installing your new battery, you may need to reset your MacBook Pro's SMC.

Conclusão

To reassemble your device, follow these instructions in reverse order.

For optimal performance, calibrate your newly installed battery: Charge it to 100% and keep charging it for at least 2 more hours. Then use your device until it shuts off due to low battery. Finally, charge it uninterrupted to 100%.

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?

I poured isopropanol into those lowered areas but unfortunately it soaked up along the battery leads and got all the way under the keyboard and elsewhere where it shouldn’t. It made some other plastic parts of the computer swell which isn’t good so I would not recommend pouring any solvent in there. Add a very small amount of solvent (0.25 ml) just enough to soften the adhesive, and let it sit for about 30 min and then pry carefully and add a little more, making sure it doesn’t get soaked up by the battery leads.

Another important thing: when you buy a battery, make sure it’s new, up to 1 year from date of manufacture because they have a limited shelf life and get permanently damaged when sitting uncharged.

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).
