The above versions of the Audi A4 are equipped with a Start-Stop system, and in this case, we should use batteries made with AGM technology. Matching batteries have dimensions 278x175x190 mm. The parameters of these batteries are at least 70 Ah of a capacity and 720 A CCA (Cold Cranking Amps). All the batteries in the list above have a base hold-down B13.
Audi A4 B9 – petrol engines:
2.0 TFSI (185 kW) – with Start-Stop system
2.0 TFSI Ultra (140 kW) – with Start-Stop system
Avant RS4 2.9 TFSI (331 kW) – with Start-Stop system
The Audi A4 gasoline engines mentioned above are equipped with a Start-Stop system, and in this case, it means there is a need to use batteries produced using AGM technology. The dimensions of batteries suitable for 2.0 TFSI (185 kW), 2.0 TFSI Ultra (140 kW) and Avant RS4 2.9 TFSI (331 kW) engines vary slightly among different manufacturers and are: 315x175x190 mm or 317x175x190 mm. The parameters of these batteries are at least 80 Ah of a capacity and 800 A CCA (Cold Cranking Amps). The base hold-down of the above batteries is B13.
Owning a Audi A4 with a S4 3.0 TFSI (260 kW) engine and Start-Stop system means there is a need to use more expensive batteries made with AGM technology. Matching batteries have dimensions 353x175x190 mm. The parameters of these batteries are at least 95 Ah of a capacity and 850 A CCA (Cold Cranking Amps). All the batteries in the list above have a base hold-down B13.
Audi A4 B9 – diesel engines:
30 TDI Mild Hybrid (100 kW) – with Start-Stop system
35 TDI Mild Hybrid (120 kW) – with Start-Stop system
S4 TDI Mild Hybrid (255 kW) – with Start-Stop system
The diesel engines of the Audi A4 listed above have a Start-Stop system, and in this case, this means that we must use batteries produced in AGM technology. Batteries suitable for 30 TDI Mild Hybrid (100 kW), 35 TDI Mild Hybrid (120 kW) and S4 TDI Mild Hybrid (255 kW) engines have dimensions of 278x175x190 mm. The parameters of these batteries are at least 70 Ah of a capacity and 720 A CCA (Cold Cranking Amps). All the batteries in the list above have a base hold-down B13.
