I think the battery swelling issue is due overheating or it might be the factory problem. Because I have another Macbook, using it same way and don’t have any battery swelling problem.

Now it’s time to fix the swollen Macbook battery issue, but first make sure that:

  • Battery is fully discharged. fully!, discharged!
  • You are at fully ventilated area
  • Use of gloves and goggles recommended

You need a needle to create tiny holes on each cell of the battery and release the gas from inside it. You need to peel the tape a little bit first and then create a hole into it. Dig a hole with needle in flat position. Don’t just vertically push the needle inside.

Now put some pressure on the battery cell with your hand and push out the gas from one side towards the created hole by swiping you hand on the battery cell.
