For these petrol engines, we recommend batteries with dimensions of 242x175x190 mm and a capacity exceeding 59 Ah. The weakest of these is the battery Bosch S4 S40 05 which capacity is 60 Ah and Cold Cranking Amps is 540 A. The most powerful battery is Lucas Supreme LS027 of a capacity 65Ah and Cold Cranking Amps: 640 A. All of the above motors have a base hold-down B13.
The Audi A3 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. 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). The base hold-down of the above batteries is B13.
The diesel engines of the Audi A3 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 1.6 TDI, 2.0 TDI and 2.0 TDI quattro 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). The base hold-down of the above batteries is B13. If you’re still unsure which battery fits your Audi A3 , or if you want to help others in their selection, please send us a photo of your current battery in the comment section at the bottom of the page.
