If you screw up, you’ll get an alert and a chance to try again. But the reverse-polarity protection built into each of the jump starters we tested confirms that each clamp is on the correct post before completing the circuit. If you confuse them and connect positive to negative and vice versa without that protection, you’ll get sparks at the connection and potentially damage your car’s battery or electrical system. When you hook up a jump starter to your battery, you need to connect the positive (+) clamp to the positive post, and then attach the negative (-) clamp to the negative post. Safety features: While most jump starters have a suite of safety circuits to prevent sending more current or voltage than they’re designed to handle, reverse-polarity protection is what makes them notably easier to use, especially for people who are concerned about getting the connections wrong.
