44.9 volts is fine if the gravity in all cells is not unequal.
The engineer's specs at some of these battery companies revolves faster than a fart in a whirlwind. Yes I am talking about Trojan as well. They changed their charge regimen four times in eleven years when I was testing batteries. They were using xG x MM2 5% Sb. Adopting envelope separators should not have affected the chemistry but it affected their charging protocol.
"We're getting pallets of dry battery warranty"
Lower absorbsion and float
"We're getting pallets of sulfated battery warranty"
Raise absorbsion and float
I heard the chatter when I visited. Follow the bouncing ball. Political fiefdom nonsense.
Unless they deviate from alloy and electrolyte density composition, charge protocol should never change. But it's like women's fashion, and new car idiocy -- different is always better, so change it. The protocols I established thirty years ago have not changed. "Wanna screw with them?" Call one of the biggies on the telephone. Tell them you are interested in (pick one) a golf car battery. BUT! They are going to be operating in a min mat of 32c - 45c. What tropical blend and absorbsion and float voltages do they recommend?
De Injinear on da phone gonna drop it or put it on hold
Because a specification engineer is not really an degreed engineer. He is a trained salesman, with 2-years of junior college accounting.
He will then make you wait while he consults with a genuine engineer.
Alarms trip. Management picks up on extension phones. Click-click-click.
After 10 minutes the application engineer will inform you of the official edict.
Assume NO CHARGER has a correct algorithm for charging a battery. Know before you choose then choose the mechanism that closely parallels what the battery wants. When a charger finishes doing what it's paid to do, the battery must be charged 100%. Not 92% or 106%
"Uh mister. Five dollars please. Your car is washed"
"What about above the door handles?"
"We couldn't reach that high. Next time buy a lower car"
Today's lack of intellectual capacity professional wise, amazes me...and it's getting worse by the year...
