MacBook Air 13inch - New battery worked then wasnt recognised

Hi all,

I recently replaced my original battery in my Macbook Air, using an Ifixit battery and following the guide.

I did a battery calibration and then for the first 2-3 days after the replacement the new battery worrked flawlessly.

I use the laptop till about 80% charge. The next morning i go to turn it on and it doesnt boot. I plug the charger in and try to boot, it boots but no battery is shown in the tool bar. If i disconnect the charger it instantly turns off.

I cant acess any information about the new battery. I have tried using CoconutBattery:

I then followed this guide: MacBook Air Battery not even recognized after being Recalibrated

I have tried:

  • SMC reset (80s on the power button and 15s)
  • PRAM reset

When i plug my original battery back in, it is recognised by Coconutbattery:

Anyone have any ideas? could the new battery just be faulty?


Update (07/04/2022)

From further reading looks like this could be a faulty issue with the new battery.

Yep! The controller chip within the battery is bad. Contact the iFixit store for a replacement
