A frosty winter is a real test for the car battery. If the battery is left out in the cold overnight for more than a day, there is a risk that its charge will not be enough to start the engine. In such a situation, you need to go ask your neighbor for a cigarette lighter. This is where cigarette lighter wires are helpful. Multi-strand copper wires in a soft thick rubber braid will not get cold and will not melt in the heat. Crocodiles also have their own insulation. Choose from 6.5 or 10 foot lengths and up to 1800 amps of current.
