Negative first It’s important to disconnect the negative side of the battery first, otherwise you can cause an electrical short if the positive is removed first.
Why do you connect the positive terminal first?
Connect positive first, negative having less potential won’t arc. The higher the voltage, the greater the chance of arcing and fusion. On a car if negative first and you are touching any metal part of car, when attaching positive there is possibility of arcing through you. Your body becomes part of the circuit.
