Can a Car Charge Its Battery by Idling for 15 Minutes?
1 Answers
Car idling for 15 minutes can charge the battery. Car idling refers to a working condition where the engine is running in neutral gear without any load, consuming fuel without moving the vehicle or doing any work, but it can still charge the battery. Charging Precautions: Using a dedicated car battery charger, the charging current is controlled by the computer. For severely depleted batteries, the initial charging current can reach 40A-50A, and as the battery nears full charge, a trickle charge is applied to ensure better saturation and protection of the battery, thereby extending its lifespan. Hazards of Idling Charging: While idling can charge the battery, it is relatively fuel-consuming and results in severe emissions pollution during idling.
