Sizing generator to charge batteries
I currently have two costco "rv/marine" batteries which are due to be replaced. Planning to get 2x230 AH 6v Duracells for a total of 230 AH If the batteries are half empty, I have to charge 115 AH ...

1. You do not want to charge the batteries TOO fast. It will boil all the water out. That is why I do not connect my generator 12 volt output directly to the batteries. I connect the 110 Volt output to my RV and let the RV charge the battery.
2. The "charger" (DC power Converter) in the RV should limit the charge rate. If it is an expensive one it is programed to adjust the charge rate so the batteries do not charge too fast.
3. My 750 watt small generator will recharge my batteries in about 2 hours (a tank of gas) it I run it every day I am off the grid.
