after recalibration and charging it on the 4th cycle, the battery’s health is %97 and from 8600 to 8306 … I have read and followed the instructions. Done SMC reset but I am wondering what I need to do to fix this issue. The battery is made on Nov 2021 so its not old battery but the battery dropped from %30 to %12 to %2 and then shut off on the last time that I was using it. It did not happen to the other 3 times. Now, I am going to do another calibration again, another SMC reset, to see what’s the problem … can someone direct me what to do or where I could be going wrong please, Thank you.

Sadly this battery is not healthy. uI would contact the seller to get it exchanged.
