12V or 24V… how do I actually confirm what my system is before I buy the wrong battery?

Look at your old battery! Printed bold: '12V' or '24V'. If weathered: 90% of camper vans are 12V. If unsure, post a photo in the forum – we'll tell you in 3 minutes.
Jaysus, I've seen this ruin many a holiday. Quick test: if your interior lights dim when you start the engine, it's 12V. If they stay bright, likely 24V. But for the love of God, check your inverter label before buying anything!
Falsche Spannung kaufen = teures Feuerwerk. Ernsthaft: Meistens ist es 12V. 24V ist oft bei grossen LKWs oder Serienschaltungen. Was fährst du denn? Sag das, und wir raten mit 95% Trefferquote.
Easiest: use a multimeter on the main battery terminals. Resting ≈12.8V = 12V system; ≈25.6V = 24V. No meter? Borrow one—cheaper than the wrong battery
Schau aufs Typenschild vom Ladegerät/Wechselrichter: Steht da „Input 12V“ oder „24V“ – das ist meist eindeutig
