Do you always unhook the positive or negative battery terminal first? Are you sure you want to delete this answer? It's because if your wrench accidentally shorts between the positive terminal and the body, or nearby metal, it won't spark with the negative terminal already disconnected.
One site mentions sparks, but you'll still get a spark when connecting black to frame. If positive is the potential shouldn't it be keep disconnected as long as possible? Conventional lead acid batteries produce hydrogen gas as a byproduct of the charging process. This gas tends to collect in and around the battery. As you are aware making the final connection can generate a substantial spark. By making the frame connection the point where the spark occurs it is far enough from the hydrogen gas to avoid an explosion.
When reconnecting a battery, why is it recommended to connect the positive lead first, and the negative lead last? What difference does it make if they are connected in the opposite order? This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question. The reason I would connect the positive cable first in a negatively-earthed car is that while tightening the positive connector with a spanner wrench , if I were to touch the body of the car with the spanner at the same time, nothing would happen and I would be OK.
