Right after we took delivery of our Ascent, we left for vacation (without it). When we returned eight days later, the battery was dead. Although I’m fairly certain now the reason it was dead was because one of the kids left a light on in the back, I did notice something unusual when I was jump-starting the vehicle. As you can see in the attached pic, there is a white milky substance, which I immediately noticed when I removed the terminal cover. Is this normal? I haven’t had any issues since jump-starting it a week ago, but wanted to follow up on this.
