The Michelin Smart Jumper Cables™ seem to be a great step up from ordinary jumper cables. These 12′ long cables are 8-gauge copper-clad aluminum wires with a control box that automatically adjusts the polarity when the clamps are connected, and prevents sparking or shorting. Basic jumper-cable connection rules still apply: from one side of the control box, connect one clamp to the boosting vehicle’s positive battery terminal and the other to its negative terminal. Then, from the other side of the control box, connect one clamp to the disabled vehicle’s positive battery terminal, and the other to exposed metal on the engine block or vehicle frame. If the control box’s green indicator lights are on, you’re ready to try a jump start. The control box also has built-in surge protection for the vehicles’ computers and electronics. A set of these smart jumper cables costs $34.99.
These look like a good idea to me — no more of that “put the red clamp on the positive terminal of the good battery, and then…,” especially on a dark, cold, rainy night with crummy cell-phone reception. What do you think?
