I'm afraid to say that the battery is fubar'd,I suspect it's got a dead cell inside of it.
The low voltage is preventing the car from starting or even running properly,and even if the alternator is charging spot on,the battery still won't hold it's charge.
I'm afraid you need another battery,and then you can check your alternator.
I'd rather push my Alfa than drive a BMW....
