Work area is Kress's own rated maximum, converted from the 4,856 m² they publish. A robot rated below your lawn will not keep up with it.
Maximum slope is 40%, which is about 22°. Makers quote one or the other; they are the same figure, and 40% is not 40°.
Battery energy is voltage x amp-hours; run time depends on cut height, grass load and blade speed, so it isn't estimated here.
