Ich wollte die Batterie wechseln, aber bei meiner PS2 Slim ist an der Stelle der Stecker des Laufwerkes fest? Und ich kann weit und breit keine Batterie entdecken. Weiß jemand warum das so ist? Gibt es verschiedene Revisionen, so dass die Batterie noch woanders sitzen könnte?

This does not explain how to get the battery out of the black plastic, replace it, and put the wires back. That's the most important part!

I believe that is because the clock battery is sold as a single unit. So there is no way to replace the actual battery inside.
