Does Jump-Starting a Car Affect the Vehicle?

[DiPhoebe]

Jump-starting other vehicles can potentially harm your car. Here are some key points about jump-starting a car: Power supply during startup: When starting the engine, the battery provides power to the starting system, ignition system, and electronic fuel injection system. Power supply at idle: When the engine is stopped or at low idle, it supplies power to the car's electrical equipment. Protecting electronic devices: It mitigates voltage surges in the electrical system, protecting the vehicle's electronic components. Storing excess electricity: It can store excess electricity generated by the alternator for use during vehicle startup and by other electrical equipment.
