Re: it will return the current charge capacity of the battery and the design capacity.  What numbers do you see? I have seen 5-6 battery health conditions in latitude bios: excellent, good, fair, poor, need to be replaced, “not installed” (physically installed but not detected by bios).  The last one seems to be associated w swollen battery.  Do you know what charge capacity percentage corresponds to each detected health condition?  Is it 80-100% for excellent, 60-80% for good, 40-60% for fair, 20-40% for poor, below 20% for need to be replaced?
I recently purchased a refurbished a Dell Latitude 5580. It won't power up unless it plugged up charging. It will only charge up to 84% and go no higher. So I wasn't sure if it was the AC charger or if the battery needs changing. Thanks
