What Does It Mean to Jump Start a Car?
Jump starting a car means using an external power source to give your dead battery enough energy to start the engine. Once the engine is running, your car’s alternator takes over and begins recharging the battery.
Common reasons a car battery dies include:
-
Leaving headlights or interior lights on
-
Cold weather draining battery power
-
An old or failing battery
-
Electrical issues or long periods of inactivity
