Very Important!
Always remove the Negative (Black) terminal first when removing the battery. After the negative terminal is completely removed and pulled away from the battery post, then remove the positive.
When installing a battery, install the positive cable first and tighten it up all the way. Then install the negative cable last.
The reason for doing this is to prevent you're wrench or other tools from Arcing and Sparking, while tightening the positive, when you're wrench accidentally touches the body or any ground point. If the negative is not connected when you're tightening or loosening the positive, you don't have as much risk of causing those mini lightening strikes, burns, fires, melting you're wrench, or any under the hood fireworks display.
