You should leave your car running for at least 20 to 30 minutes to recharge the battery. Does idling a car charge the battery? Yes, idling a car charges the battery, but it takes a lot more time to charge it that way when compared to driving your car.
It could take days to charge a car battery by idling. If you just jumped a car, the battery is either too depleted to start the engine — or something else is wrong and idling won’t help anyway. Leaving your car parked will not charge your battery. The engine’s rpm reading is low, and the alternator is running all the electronics.
The most important thing to understand about your battery is that you must keep it charged. If you let the charge drop too low, your battery can become irreparably damaged. Not to mention you won't be able to start your car, especially when it's cold outside. So, how low are we talking?
Generally, a fully depleted battery can take anywhere from 2 to 24 hours to recharge, depending on the charger’s amperage. Fast Chargers (15-30 Amps): These high-power chargers can fill a car battery in around 2-4 hours. While convenient, frequent use of fast charging can reduce the battery’s lifespan due to the high current.
Charging a car battery safely involves several critical steps. Using a jump starter is often safer than a fast charger for reviving a flat battery, and using the right charger helps avoid permanent damage. Properly charging a car battery is crucial for maintaining its health and longevity.
