No version has factory Start-Stop, so they all take a conventional battery, from 52 to 74 Ah depending on the engine. The usual case size is L3 (278 × 175 × 190 mm). - Model fact: the Seat Leon I 1M mainly uses case sizes L3 (278 × 175 × 190 mm), L2 (242 × 175 × 190 mm) and L1 (207 × 175 × 190 mm).
