I successfully replaced the battery, calibrated it, and worked fine for 4 charge cycles…..after this the battery just went dead!
The reported “battery condition” in the system Report says: “Replace now”…(!!!??).
Battery indicator in the desktop screen reports 100% charged, but system report states battery fully charged but with amperage (mA): 0
I tried to reset the SMC as per Apple’s website instructions for this MacBook Pro (15” late 2011). It did not resolve the problem either.
Was this a defective battery?
