Ok possible stupid question but if you don’t know you don’t know lol.

Never had a battery on a car before that looks like this so on Friday I’m fitting my deplorable steps and you have to disconnect the battery. I had a little look and the positive has 3 bolts on it and the negative has 1 bolt and like a rectangular board thing behind lol?

So would someone just confirm the circles bolts are the ones to undo lol?

Cheers

Yes, but you only need to disconnect 1 and the negative is the safest if your spanner touches the body while removing or refitting.
