Introduction

Use this guide to remove the glued-in battery from your MacBook Pro. This is best done with the help of an iFixit battery replacement kit; the liquid adhesive remover in your kit will dissolve the adhesive securing the battery, allowing you to remove it with ease. Alternatively, you can use an iOpener to apply a modest amount of heat in order to soften the adhesive before prying out the battery.

iFixit adhesive remover is highly flammable. Perform this procedure in a well-ventilated area. Do not smoke or work near an open flame during this procedure.

For your safety, drain your MacBook Pro's battery before you begin this procedure. A charged lithium-ion battery can create a dangerous and uncontrollable fire if accidentally punctured. If your battery is swollen, take extra precautions.

Note: The solvent used to dissolve the battery adhesive can damage certain plastics, such as the MacBook Pro's plastic speaker enclosures. Take care when applying the solvent.

If you're using the old-style iFixit adhesive remover with separate bottle and syringe (no longer sold), click here for a slightly modified set of instructions.

    • Before installing your 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.

is it possible to use MBP early 2015's battery on a late 2013 model?

Thanks to this guide I saved my broken MacBook Pro from a coffee spill that killed the battery. It cost me about 30% compared to what it would have cost to have the battery changed at an Apple authorized repair center. It wasn't easy to do, but that just made it all the more satisfying.

One comment: the new battery pack I bought came attached to a thin film which had to be removed. I unfortunately tore off some of the strips of glue attached to the back of the battery cells, before getting the hang of it. No big deal. But if you have to do the same thing: peel slowly.

After i replace the battery, the new battery is outofsync with osx battery indicator. When the indicator hit the 30% mark the macbook just shutdown completly. How do i syncroniz the new battery with osx?

The tutorial i saw only, tell you to fully charged the battery and let it depleet until the warning message pop up that your battery is low and your mac go into sleep mod. Problem my mac cant go into sleep mod because it thinks that it has 30% left of juice.

Is there any method to change the sleep setting or to force a recalibration?

I would download an application called coconut battery from here: http://www.coconut-flavour.com/coconutba...

This will indicate your battery's current health (I am not sure how accurate it is or how it measures the milliamps/hour) which might help you determine when you need to recharge it. I don't know what else you could do but I'd check the battery's health before anything since it might be causing the problem if it is faulty.
