The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses a B13 hold-down and A-Pole terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### What Q-Battery does differently The Q-Battery catalogue runs from small alarm batteries to large traction monoblocs, always with sealed, maintenance-free technology.

To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on.
