Left lights on 2014 Hyundai Elantra
I stupidly left my headlights on for
48+ hours but it started up right

get so lucky that my battery didn't
No worries, most newer cars turn power drains off when key is not on. My Yukon lights inside and out go out after a few minutes with my hatch open and doors open, and even the radio shuts off after five minutes. I work out of the back of my Yukon and never have to worry about battery going down.
