The man said it Always connect the positive + cable first to the battery. Then connect the negative- cable to the engine somewhere. Never connect the negative cable to the battery itself. Batteries vent hydrogen gas and which can ignite with the slightest spark. For this reason never, ever, connect the negative first and never connect the negative to the battery.
You don't, you connect to the battery from the battery of another car. Use the positive cable to connect the two positive electrodes and the negative to connect the two negative electrodes.
