Newly replaced battery crashes at ~30%; suspicious battery levels

Hi all,

I have just successfully* replaced my MacBook Pro Mid 2014 battery using the iFixit guide and kit. I am noticing now two main issues, which I assume are interconnected:

  • When running on battery, the computer crashes at ~30% and cannot be powered back on until it is plugged in with the AC adaptor.
  • The displayed battery levels & charge times on the menu bar are suspicious.
    • I have *just* plugged in my device and it is at 28% with an expected charge time of 8:25 until full.
    • While infrequent, I have seen the displayed battery level % jump from the 25-30% threshold up to 50-70% for a moment before jumping back down

I suspect (and hope) this is a calibration issue.

Steps I have taken thus far:

  • Initial calibration (charge to full +2 hours; drain battery and wait 5 hours; charge up to full)
  • Reset SMC
  • Reset PRAM
  • Checked System Info - Power (see attached screenshot)

Hi Dan,

Thank you so much for your help. I am writing the iFixit Team now regarding the issue.

In your experience, is there a simple way to use 1st or 3rd party diagnostics tools to 'show' the problem with a battery?
