This is not exact, it is only based on my general observations. After dry camping for 7 days, my 6v battery bank of 225a were down to about 50 percent, or down about 110a. Drove home which took about 9 hours. After resting the batteries over night, they read 6.4v which for me that is close to 100 percent, or a gain of about 110a. Not scientific, full of errors, but good enough info for me to understand what my system needs to keep traveling and dry camping.
I realize this doesn't answer your specific question, but this is what I can offer.
