My car sits outside all day at work with no shade, and I'm on my third battery in five years. That feels excessive but I'm not sure if it's the heat, bad luck, or something else. A colleague mentioned some Quality tips on how extreme temperatures affect your car battery and it got me thinking about whether my parking situation is the culprit. Has anyone else noticed batteries dying faster when parked in direct sun versus covered parking? And is there anything practical you can do to protect a battery if you don't have shade, or do you just accept it?
