Alternator: Charging leisure batteries ... (1 Viewer)

For those who don't use camp sites and depend on using the alternator as a charger .. this may be a worth while investment ..

THE PROBLEM:

Standard alternators are not designed to be good battery chargers; they are designed only to charge an engine start battery sufficiently to start the engine. Because of this inherent design problem associated with the standard regulator, a more advanced regulator is required which in effect converts the alternators from a constant voltage power supply to the latest 4-step constant current battery charger (see battery charger graphs). Because of this improvement in the alternator control system, these regulators dramatically enhance the alternator's charge rates by between 200-2000%,depending on how poor the original system is.

I fitted one of these onto my Yacht but it was made by "Adverc" and it done a great job and would recommend them. However I have reason to believe that computer controlled engines already have this type of control of the battery. IE when I measure the engine battery voltage when the engine is running the voltage is above 14.0 volts, now this is not possible with an alternator that is controlled by a machine sense voltage control.
