Yeah, just ask any alt. rebuilder. I work on cars every day, and can testify to it. When you buy a new alt. it comes with a data sheet. In large print ( usually) it will tell you to charge the battery fully because it will not charge a weak battery. An alternator will maintain 14 volts, not recharge the battery to 14v. While the vehicle is running, there are many things that need this voltage to operate, thus relying on the alt. output. It will put a little bit of a charge back into the battery, but will not fully recharge it.
