Remove Positive Or Negative First Car Battery. You should always remove the negative battery terminal first to reduce the risk of sparks which can make the car battery to explode. When you are replacing your car battery It isnt always easy to remember the order in which to disconnect and reconnect the terminals.
Use a socket wrench to loosen the nut on the black or negative terminal. The nut on the negative terminal of your battery can be held against if you grab a sockets from your kit. Besides the short circuit insurance issue there is a school of thought that says removing the negative first reduces the chances of a spark happening at the moment the circuit is opened and this spark igniting the hydrogen gas around the top of the batterysounds like a Mr wizard issue to me.

If you begin to remove the positive side before the negative and your wrench would make contact with any part of the vehicle then you could cause a short in the system. Whole car except a few parts like the positive pole are connected.
