How much charge can idling for 10 minutes provide to a car?
1 Answers
Idling for 10 minutes can charge the battery to approximately 6% of its capacity. Charging duration using the car's alternator: When the car battery is dead, using the vehicle's alternator to fully charge the battery requires the engine to maintain a speed above 2000 RPM, equivalent to driving continuously for at least 4 hours. However, idling for just 10 minutes can charge the battery to about 6%, which is equivalent to the battery drain from parking the car for one week, and so on. Car battery maintenance: Car batteries are relatively fragile components. With each charge and discharge cycle, the battery's performance gradually deteriorates. Under normal circumstances, with proper usage habits, a battery can last 3-4 years, and its lifespan may even be extended. If the car is not used for an extended period, it is recommended to disconnect the negative terminal of the battery. This prevents the battery from activating its self-protection discharge function, thereby avoiding battery depletion. Prolonged depletion can lead to permanent battery failure. Avoid using electrical devices in the car for extended periods while the engine is off; refrain from repeatedly starting the vehicle without intervals; do not use external power devices while the engine is off; and always remember to turn off the car lights after parking.
