## Definition

A terminal (or post) is the physical connection where the vehicle's cable is bolted to the battery. The **EN standard types for passenger cars**: B0 (large taper, 19.5 mm + / 17.9 mm −, majority in Europe); B13 (same taper but with M6 bolt for Start-Stop systems); B19 (with side extension for Japanese cars). On **motorcycles** the terminals are F1 (M5 screw with nut) and F2 (flat Faston type). On **trucks and heavy machinery** they are Stud (threaded M10 or M12 post) or special DIN. Adapters exist for edge cases but they are NOT recommended (poor connection = high resistance = voltage drop on starting). If your original battery has a given terminal type, the replacement must match.
