Apple A1582 Battery Replacement: Step-by-Step Guide for Your MacBook Pro 13" Retina A1502(EMC 2835)

Apple A1582 Battery Replacement Guide

Before starting, make sure your laptop is fully powered off and unplugged from any power source. Use the right tools—typically a screwdriver set included in the package—and work on a non-conductive surface to prevent static electricity damage.

This tutorial will guide you in detail how to remove the Apple A1582/ MacBook Pro 13" Retina A1502(EMC 2835) battery. You can watch the tutorial video below.


Step 1

Remove the following ten screws securing the lower case to the upper case:

  • Two 2.3 mm P5 Pentalobe screws
  • Eight 3.0 mm P5 Pentalobe screws

Throughout this repair, keep track of each screw  and make sure it goes back exactly where it came from to avoid damaging your device.

Step 4

Use the flat end of a spudger to lift the battery connector straight up out of its socket on the logic board.

Be sure you lift up only on the connector itself, not the socket, or you risk permanent damage to the logic board.

Step 17
  • Pull the trackpad cable away from the battery adhesive tape.
  • Be careful not to damage the cable. If it doesn't pull up easily, apply some heat with a heat gun or hair dryer to soften the adhesive and try again.
  • If you are installing a new trackpad cable, make sure the new cable matches the shape of the old one. If you don't fold it over, the new cable will be too long.

Step 18
  • If necessary, peel off any tape covering the trackpad cable.
  • Use the end of a spudger to unlock the slider on the ZIF connector.

Step 20

Remove the single 3.7 mm T5 Torx screw securing the battery board to the upper case.

Step 21
  • Apply a small amount of adhesive remover evenly around the edge of the rightmost battery cell.
  • Wait 2-3 minutes for the adhesive remover to penetrate the adhesive at the bottom of the battery.

If you don't have adhesive remover, you will use a heat gun or hair dryer to warm and soften a portion of the adhesive securing the battery to the upper case, then carefully pry at that time.

Step 22
  • Push a plastic card between the right-most battery cell and the upper case to cut the adhesive between the two.
  • Be careful not to damage any of the batteries with the tools during this process. Damaged lithium-ion batteries can leak dangerous chemicals and/or catch fire. Use only plastic pry tools
  • If you encounter significant prying resistance, stop and reheat the section you are working on.

Step 23
  • Repeat in the adjacent battery cell.
  • Place a small amount of liquid adhesive remover underneath the battery cell and wait 2-3 minutes for it to penetrate and soften the adhesive.
  • Alternatively, you can reheat this section with an iOpener if needed.
  • Push the plastic card in about an inch between the battery cell and the upper case and slowly pry the battery apart to separate all of the adhesive.

Step 24
  • Repeat the previous steps to separate the two left-most batteries.
  • Remember to apply a small amount of adhesive remover under each battery cell and wait 2-3 minutes for it to penetrate and soften the adhesive.
  • Use a second plastic card to separate the two left-most batteries from the upper case.
Apple A1582 Battery Replacement Guide

Step 25
  • Continue to repeat the prying steps.
  • Insert a plastic card between the second left-most battery cell and the upper case to cut the adhesive bonding the two, and pry the battery away from the case.

Step 26
  • If using liquid adhesive remover, add a few drops of remover to the center of each of the two outermost cells.
  • Lifting one side of the MacBook Pro by a few inches can help the adhesive remover flow in the correct direction under the battery. You can use a sturdy book or foam block to elevate one side of the MacBook Pro.
  • Allow the adhesive remover to penetrate for 2-3 minutes before continuing.
  • Gently fold the right-most battery cell and insert the plastic card correctly under the center battery cell.
  • Push the card in about halfway through its length to cut the adhesive between the battery and the case.
  • Avoid touching the trackpad and align the card where the adhesive is - on the logic board.
  • Leave the card in place to prevent the adhesive from resealing.

Step 27
  • Repeat the same process on the remaining battery pack.
  • Lift the outer battery cells and insert the plastic card about halfway into the left center battery cell, avoiding the trackpad.
Apple A1582 Battery Replacement Guide

Step 28
  • Return to the plastic card under the right center battery cell and twist it to separate the entire battery from the upper case.
  • At this point, you have cut through the adhesive between the battery and the upper case, and the battery should come out easily.

Step 29

Remove the battery

  • Before installing the new battery, remove any remaining adhesive from the MacBook Pro case.
  • If you're lucky, you can slowly peel the adhesive off with your hands.
  • Otherwise, soak each section of adhesive with a bit of adhesive remover for 2-3 minutes, then scrape it off with an opening pick or other tool. This can take quite a bit of work, so be patient.
  • Wipe off any remaining adhesive remover and give the MacBook Pro some time to air dry.
