How long does it take to recharge the battery after starting a car?

10 minutes. Common starter specifications are 12V, 2000W, with a rated current of about 166.7A. Research shows that the current required for starting a typical DC motor is about 5 to 7 times the rated current. Taking 5 times as an example, that's 833.5A, lasting for 1 second. However, most ordinary household cars take about 3 seconds to start. Based on calculations, starting the car once consumes approximately 32AH of electricity. More relevant information is as follows: Note 1: Whether using a traditional key or push-button start, always first power up the entire vehicle's electrical system (turn to the ON position) to allow the vehicle to perform a self-check. Wait for the indicator lights to turn off before starting the engine. At this point, the self-check is complete, and oil pressure has been established. Note 2: After starting, continue to warm up the car while driving. Once the engine speed returns to the normal range, you can proceed to drive. However, avoid accelerating abruptly at this stage. It's best to drive in gear, keeping the engine speed below 2000rpm. Right after starting, the water temperature in the engine's radiator is still relatively low. Drive at low speed for 3-5 minutes until the water temperature reaches the normal range (around 90 degrees), after which you can drive normally.
