Which battery a Audi Q2 takes
AGM throughout most of the range, with battery coding required so the energy management system knows what it is charging. On the Q2 specifically, which the vehicle database lists across model years 2016 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.
