There are generalizations, what you're finding from the "calculators" and "formulas", but those are just best guesses.
Some say divide RC by half, some say divide by half and add 16...you can see why this is a problem. It looks like your 96AH rating was concluded by dividing RC in half and adding 16?

If the battery manufacturer hasn't tested for AH and made that info available, somewhere, then the only way for you to truly know is to perform some testing on your own.
Correct on the way I got 96. I will forward your thoughts to Champion and see what they say.
