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 ...

800w should power a 30 amp converter
But it will take about 6 hours to recharge the batteries
Because the batteries are constantly tapering the charge
It won't be 30 amps for 4 hours
In many cases, with only two 6v
It won't be 30 amps for even one hour
In 3 hours you will get back to about 80 percent charge
You will return roughly 70 amp hrs, not 115
If your down 115, it will take approx 130 to get to full charge
From the converter,
some of the power is lost to the The rechargeg process
You can feel it, in the battery warning up
It is electro chemistry, and it is PITA
