Lesee, since the 10SI Delco alternator was introduced some forty years ago with the 1116387 voltage regulator, 14.4 volts was the temperature compensated point of regulation. The the 15 SI alternator was introduced with the 1116405 voltage regulator set a T/C 15.0 volts.
Until someone in the industry gets off their dead A$$ and introduces a user adjustable authentic converter we shall continue to see the Wizard of Oz, Toto, Looney Tunes, and Car 54 Where Are You, bad charger jokes on the shelves.
Can the BOONDOCKER get to 14.8 volts, and stay there for long enough to raise the battery acid specific gravity within reasonable distance of seeing 95% state of charge? I do not know. I do know there are seven hundred to three thousand dollar chargers that can do it but they are almost always transformer based not PWM. Is there a converter out there that can do this? Fourteen point eight volts. Wit some free time investigate the TIME needed to fully recharge a 50% depleted battery with various voltages. I do not like fifteen volts! It overheats antimonial plate grids too easily when used continually. For a 20-minute top charge fine. For a few hours, no.
The SOLE converter I am aware of that works according to user specs in the quarter-century old Trace 2500 SB inverter charger.
But who knows maybe there is something out there that can work as good. I'm sure open to suggestions about this.
