Update: "dead" 12v battery turned out not, I jiggled the wires

As the title suggests, I went to take a picture of my 12v battery so I could show Autozone what brand it is. When I moved some wires around the battery I heard an electric hum, sure enough I went in the car and the car turned on with display and all. Am I in the clear? I have a day trip planned tomorrow, it's 100 miles. I feel like it's ok now? Thoughts would be appreciated
