I'm no electrician but I think it's not the voltage value that charges the batteries. After all, it's the same in every car. The current intensity.
After all, logically you have smartphones and chargers. Each has an output voltage of 5V but different amperes. With a small A it charges slowly and vice versa with a large A it charges quickly. So the fact that the alternator charges at 14.5 volts is no indication of how fast it charges the batteries. That's how it seems to me
