    Alright so I have a Macbook Unibody A1278 13", The problem is the battery is not depleting a charge at all, well its not showing it. It says Replace Now, when I pull the mag safe charger out it calculates it to 20:00 and never moves from 100% or the calculated time. I mean it takes about 30 minutes to drain, but the battery will still say 100% till it dies. I have Battery Health and CononutBattery, and both are telling me innacurate readings. I mean its saying "Current Max - 64347 mAh" and "Original Max - 4100 mAh". Could it be the battery going out that can cause the readings to be so off and the mAh readings to be off the charts?


    All the attachments are screenshots of the readings I have gotten.

    Most likely it's time for a new battery. You can try resetting the SMC, then calibrate your battery using exactly the procedure in the CALIBRATION section of the link below. If that doesn't help, it's time to buy a new battery.

    This should answer most, if not all, of your battery/charging questions:
