The click click sound of a dead battery is one of the worst things a motorist can hear. It seems to only happens when you are pressed for time or when the weather is terrible. A dead battery is an especially common occurrence in the dead of winter. The freezing temperatures are often very hard on batteries and can sap the power right out of one if it has not been properly maintained. When it is cold outside, the last place you want to be doing is under the hood trying to coax one last start out of a worn out car battery.
