Which battery a Volvo 66 takes
AGM with a support battery on many recent models, and coding is required so the car charges the new one to the right profile. On the 66 specifically, which the vehicle database lists across model years 1975 to 1980, 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.
