Which battery a BMW iX3 takes
BMW batteries must be registered to the car with a diagnostic tool. Without registration the alternator continues charging to the old battery's profile and the new one is ruined within months. On the iX3 specifically, which the vehicle database lists across model years 2020 to 2026, the safe approach is to read the label on the battery that is in the car now and match its group size, terminal side and capacity — or to give us the year and let us look it up.
