In the video, we see a fundamental principle for the correct assembly of the battery: the nut (the threaded part that is screwed on) should always be on the cable side, and not on the battery side. This is because when tightening, the torsion force is applied to the bolt head; if the bolt is on the cable side, it is the bolt that turns in the fixed nut, and the cable and the terminal remain stationary. If, on the other hand, we do the opposite, when we turn the bolt, the nut and the cable will turn together, risking twisting the electrical cable, making tightening difficult, and damaging the lead terminal of the battery. The universal rule is then always to connect the positive terminal (red) first and only then the negative one (black).
