When I read the title of this video ("Insane Battery Hack") I thought, "what could be so insane about a car battery hack?". But then I watched it. Yep, it's kinda insane. I must admit, I'm not too sure it's accurate. I replaced the battery in my wife's car a few months ago, if only I'd known this hack then, I'd found me all kinds of neat stuff (mainly certain death and destruction).
