Another question on Converter sizes
There is another active thread regarding converter sizes, but I get lost in the wealth of detail offered here. I have a simple question: I have a PD 9200 , 45 amp converter, two Trojan T105 batteries ...

This thread, the OP is just wondering why he is not seeing the 14.4v at the battery when he STARTS charging.
The OP's charging current is to low. :?
In the case of the automobile alternator, the available current will greatly exceed the Amps used to start the vehicle. Starting will likely use <5% of the battery's AHs. The alternator's current is so much higher than the missing AHs, the bulk stage is nearly instant and you don't notice the Volts rising to the Absoprtion Voltage.
In the typical RV, the house charger's current is way below the missing AHs at the time charging is initiated. The bulk stage takes much longer to accumulate enough AHs into the battery and that is when the battery's Volts slowly rise to the Absorption Voltage.
