drove home perfectly fine parked car, next day car will not start, only makes a clicking sound, battery saves fine, please help

 

Hi , do you mean Battery says fine , and where does it say fine . Is this on a multimeter ? You might have 12v , but not enough power and a dead cell . You need to do a drop test on the battery terminals with the battery leads off!!!! If there is not enough power , your electric system can detect low amps , and stops you energising the starter to save its life. The other thing you obviously chacked is that the terminals are clean and earthing is good. Hope that helps .
