Corroded Battery Terminal

Cars break down, it's what they do.  My dad has had to remind me of that whenever things go wrong with my not-so-new 2001 Corolla.  Typically, I wouldn't consider changing a dead battery an issue, but it becomes one when the terminal breaks after years of use and corrosion.  It becomes an even bigger issue when the bolt connecting the broken terminal to the cable won't come loose, your car is parked half-way in the garage at night during a rain storm, and you have a dinner appointment with a friend in two hours.  After conferring with my friend Josh in AZ over text, using a lot of WD40, praying, and finally figuring out how to position two wrenches to apply enough pressure to loosen the bolt, I was finally able to replace the terminal 1 1/2 hours later.  The bottom right picture shows all that was left of the old terminal after the saga.  My arm was sore the next day, but my car starts now!
