My 2015 435i is in need of a new battery. Few weeks back I was able to find decent brands like Bosch and Exide online but now they are either discontinued, or they cannot be shipped because they contain hazardous materials. I'm not sure if suddely laws have changed but Iooks like I'm stuck with the type of brands that are available locally. Is duralast a good option? This is the only brand I can find in store or online from places that are willing to ship. Of course, the dealer is out of question as they quoted me $400 for a new one.
