  • Plastic pry tool
  • Tweezers
  • Adhesive remover
  • Replacement battery

Safety Tips Before You Start

Battery replacement requires care because lithium-ion batteries can be dangerous if damaged.

If the battery appears swollen, handle it carefully and consider professional repair service.

Step 1: Remove the Bottom Cover

Use the appropriate screwdriver to remove the screws from the bottom case.

Place the screws safely aside because they may vary in size.

Carefully lift the cover using a plastic pry tool.

Step 2: Disconnect the Battery

Locate the battery connector attached to the motherboard.

Using a plastic tool, gently disconnect the battery connector before touching any internal components.

This helps prevent electrical damage during the MacBook battery replacement process.

Step 3: Remove the Old Battery

The battery may be secured with screws or adhesive depending on your MacBook model.

For Screw-Mounted Batteries

  • Unscrew the battery carefully
  • Lift it slowly from the casing

For Adhesive Batteries

  • Apply adhesive remover carefully
  • Wait a few minutes
  • Gently loosen the battery using plastic tools

Never force the battery out aggressively.

Step 4: Install the New Battery

Place the replacement battery into the correct position.

Secure it using:

  • Original screws
  • Replacement adhesive strips

Reconnect the battery connector carefully.

Make sure the battery fits properly before reassembling the laptop.

Step 5: Reassemble the MacBook

Reattach the bottom cover and tighten the screws carefully.

Avoid overtightening because it may damage the casing or screw threads.

Step 6: Test the New Battery

Turn on the MacBook and connect the charger.

Check:

  • Charging status

  • Battery recognition in macOS

If everything works correctly, the MacBook battery replacement was successful.
