2 years is pathetic. I have replaced three batteries in the many ICE cars I have had. 2015 Audi A3 just before I got rid of it at 5 years. Toyota Previa ('87?) at 5 years and 2004 Jag XJ8 at 10 years before I gave the car to my niece (the battery was still performing its job!) Have a 1M BMW at 9 years and 50K miles and bimmers are famous for being tough on batteries. I don't get this at all ( tho I LOVE the car anyway!)
