Based on the specs of that battery on the bigtimebattery site, that is the service battery not the starter battery.
Did you also replace your starter battery with an Optima battery?

I replace the service or accessary battery with the Optima. I didn't look too hard for the main battery, maybe they have one that is the right size and specs. Maybe I will stop by their booth at the next SEMA show and try and convince them to make one. It would be a good product for them to sell considering the problems with buying a Mercedes OEM battery and it would fit all S class from 2003 on
