So I'm in that annoying position where my battery is showing signs of giving up (slow crank in the mornings, interior lights dim when I start the car) and I need to make a decision in the next few days. My mechanic recommended Delkor and said they handle the heat better than most, but they're about 30% more expensive than some of the cheaper brands I'm seeing around. I've been burned before by buying cheap batteries that barely last a year, so I don't mind paying more if it actually means I won't be stranded somewhere in August. The problem is everyone claims their battery is "high quality" so it's hard to know who to trust. I was doing some reading online and ended up on batteryzoneuae.com/delkor which had a decent amount of info about the specs and warranty. Has anyone here actually used Delkor in a German car for two or three summers? Do they really last longer or is it mostly marketing? I drive a 2017 Audi A3 if that matters. Really just want something that won't leave my wife stranded somewhere.
