Battery issues

[atayl0r]

I bought my computer a year ago, and recently noticed that the battery will only charge to 82%. I then did a battery test and it said it needed to be calibrated. I calibrated it twice, with no change. After it was finishing calibrating both times it said

Battery Check: Primary - replace 

and 

Primary Logic State - Calibration Required, Charge state - Blown fuse

I do not understand why it would say replace because all of the other tests said it was fine. 

Can someone help with this?

These messages say the battery needs replacement. If the laptop is a year or less old its under warranty.
