Trojan is like every other OEM. They are afraid of customers who have an uncanny ability to screw up a steel ball with a feather duster.
Sorry, but Battery Council International trumps Trojan Battery Company.
16.0 volts is appropriate for EQUALIZATION charging ONLY. PERIOD. But equalization charging the CORRECT WAY is getting impossible to do because of idiotic fear by charger manufacturers. A message for some forum participants: Sometimes equalization and recovery is hard to do. Even at 16.0 volts. I've seen too many high antimony batteries to keep track of DEMAND 16.0 volts for 24 - 36 hours. Drop voltage to 15.5 and you are talking five full days at 24 hours a day. A generator will love you for this. 120-hours of operation. How much fuel is that? Obviously this apples to off-grid.
Top charging likes charging to 15.0 volts
BOTH EQUALIZING AND TOP CHARGING REQUIRE A CONSTANT AMPERAGE OF FIVE PERCENT OF TOTAL BATTERY AMP HOUR CAPACITY.
The fastest safe charge level is 14.8
What takes an idiot smart charger 9 hours to do, when they rise to 14.4 for minutes then droop to an intermediate voltage, will take 2-hours at a constant 14.8
This is intelligent for boondocking?
What happens when a smart charger meets a sulfated battery? You'd better be hooked to public power cause you ain't gonna like my answer for how long it'll take if ever to drive sulfation back into solution.
Connection to public power is magic. Batteries have hundreds and thousand of hour to correct.
Connection to a generator is different. A world apart.
Like the difference between baking with a gas stove oven versus a campfire.
Yes, managing batteries when connected to public power is ideal with a smart charger, er, that is a few smart chargers.
Change this to generator connected charger then you tell me which smart charger has a prayer of managing batteries correctly.
Achieving 83% state of charge that takes forever running a generator ain't smart living.
Maybe 83% works for you. Just don't tout it that it works for everyone.
