The S.G. depends on the maker's choices. My AGM are a surplus acid design with a specific gravity of 13.00. Battery University suggests the average is 12.65. I know BFL13 aims for 12.75 on his.
As a result, I have to be careful to not deep cycle my bank, so I treat it as if it were made from flooded batteries with the exception of not equalizing.

A fully charged battery as a specific gravity of 1.255 and a totally discharged battery has a an S.G. of 1.110. This means that not all the sulfur/acid in the mix is on the plates waiting to be returned to the electrolyte.
A specific gravity of 12.75 or 13.00 is really, really, really high. I think you probably mean 1.275 or 1.300 don't you?
