When you try to start your car and realize that the battery is dead, it can be a frustrating experience. Many drivers carry jumper cables, so the car can be jump started by another car or some other source of power. This temporary connection can start the car by providing enough power to crank the engine. After that, the normal charging system recharges and the jumper cables are then removed. Leaving the engine running can restore the original charge. Driving the car for a few minutes can help continue the recharging process.  The owner’s manual for your vehicle outlines safe procedures for how to jump start a car. Following these recommendations can prevent any damage to your battery.
