Battery charging voltage

According to Audi Workshop Manual Charging Voltage must not exceed 14.4V, and.....
A battery terminal voltage of 12.5V is expected to be normal at no load. (i.e. measure with a voltmeter with the negative terminal cable disconnected.)
A no-load voltage between 11.6V~12.2V would indicate a totally discharged battery.
I checked my charging voltage and it is 14.2V. I would have thought a 13.8V charging voltage should be OK.

Yeah alternator seems to be ok, but battery is dead. Just replaced it with a new BOSCH not the easiest job in the world, trying to get to the 6mm allen bolt at the front of the battery is a real pain first you have to remove the rubber seal on the secondary firewall, then lift the clips on the foam cable thingy and then you can just about get a 1/4" drive allen socket on it, but if your short like me i had to kneel on the engine to reach!!!!
