Will the car keep consuming electricity if the door is not closed?

If the car door is not closed, it will continuously consume electricity. Leaving the door open can lead to battery drain and, over time, damage the battery. When the car is not in use, it is necessary to turn off all electrical appliances, close the doors, and lock the central control. The operation of car doors and windows relies on the battery for power. Before turning off the engine, all windows should be closed, and after turning off the engine, the doors should be closed. After leaving the car, use the long-press lock button method to secure the doors. Car starting precautions: 1. Before starting, open the ignition switch and wait for about 5 seconds to allow the fuel pump to operate before starting; 2. After starting the engine, turn on electrical devices such as headlights and radios. Before parking, turn off these power-consuming electrical facilities first and then shut down the engine.
Yes, leaving the car door open does drain the battery because the interior lights stay on, acting like a tireless nightlight. The battery gets slowly depleted this way. I once had a friend whose car door wasn’t properly closed, and the lights stayed on all night—the next morning, the car was dead and couldn’t even start the engine. It’s a good idea to double-check that all doors are securely closed, including the trunk, as it can also trigger the lights. Additionally, some cars have alarm systems that beep to warn you if a door isn’t properly shut. Remembering this small detail can save a lot of hassle. Make it a habit to confirm the doors are locked before leaving—not only does it save battery, but it also saves your wallet, as replacing a battery isn’t cheap.
