Answers :

The max charge voltage is usually around 14.5 volts, so 14.4 is not high.
Its possible the battery has a dead cell and that is causing the acid problem.
You might want to check with the dealer on what the max voltage is for your car.
Replace alternator have field problem. best replace whole alternator with new voltage regu;ator. i would replace battery cables also if they are old as the vechcle.
