A decent battery test will find a faulty battery wether it's been charged or not.The tester puts a load accross the battery and it will measure the voltage drop.Even if the alternator is charging corectly,the test will show wether the battery is holding that charge.I suspect yours isn't.
(Make sure you know the radio code before having the battery disconnected)
I'd rather push my Alfa than drive a BMW....
