Jump starting

Main article: Jump start (vehicle)

A car with a "dead" (discharged) battery can be made to start by supplying it with power from an external source, such as the battery of another car. The cables used to make the necessary temporary connection are also commonly called "jumper cables". These usually are equipped at the ends with alligator clips.
