For these engines, no matter if we have a Start-Stop system installed in the car, we should use batteries made in AGM technology. We choose batteries of 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 engines of the BMW Z4 listed above have a Start-Stop system, and in this case, this means that we must use batteries produced in AGM technology. Dimensions of matching batteries differ slightly depending on the manufacturer and are 315x175x190 mm or 317x175x190 mm. All the batteries in the above list have the same capacity 80Ah and Cold Cranking Amps: 800 A. All of the above motors have a base hold-down B13. If you’re still unsure which battery fits your BMW Z4 , 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. You can also send the picture to contact@whatbattery.co.uk (we will place it in the comments to also help other users). Be sure to specify the car model, year, type, as well as the engine capacity and power. We’ll do our best to assist you!
