Start-Stop-Automatic – which running performance did you achieve with 1st starter and 1st battery?

Hi, a start-stop automatic, which is now installed in almost all new vehicles with internal combustion engine, demands starter and battery a lot more than in vehicles without this accessory. It is emphasized again and again that the starter system is technically designed for this additional load, but I would be interested to see what it looks like now in practice. How many kilometers has the start-stop automatic worked reliably in your vehicles, Since, of course, it also makes a difference whether the vehicle is used as a commuter car in long-distance traffic or as a short-distance city car, this information would also be interesting in this context.
