I'm looking for a battery that will fit for you and that you can buy in Germany. The battery that will do it if a different tech than what is normally used in Germany and the rest of Europe. The one you selected is fine but I going to check the physical size to see if it will fit.
They have a 1000 cca battery but this one comes in a case that is too large. I think we should stay away from AGM batteries as they will not benefit us in the cca's we want.
You should be able to up to the Exide Premium model EA770 and get a maximum CCA = 760
Take the battery try in and confirm it.
btw: Batteries can be moved to truck for racing issues or for personal reasons. Can't think of anything that moving batt will help you for your situation.
