Which battery a Mercedes-Benz CL-Class AMG takes
Most modern Mercedes run a main AGM battery plus a smaller auxiliary battery, and the new one must be coded to the car — skip that and the intelligent charging system will not charge it correctly. On the CL-Class AMG specifically, which the vehicle database lists across model years 1994 to 2014, 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.
