Can leaving the car lights on overnight drain the battery?

Leaving the car lights on overnight can indeed drain the battery. If the car is equipped with halogen headlights, the battery may last only about 5 hours. For vehicles with xenon headlights, the battery can typically sustain the lights for around 8 hours. To maintain your car battery in daily life, pay attention to the following tips: Avoid prolonged parking: Avoid leaving your car parked in an open parking lot for extended periods. If long-term parking is necessary, remove the battery to prevent freezing damage. Monitor engine starting time: Car engines are harder to start in winter. Each attempt to start the engine should not exceed 5 seconds, with at least a 15-second interval between attempts. If the engine fails to start after several tries, check other potential issues such as the electrical system, ignition coil, or fuel system. Avoid continuous starting attempts, as this can lead to battery damage due to excessive discharge. Regularly charge the battery: Car batteries require regular charging. A battery left unused will gradually self-discharge and eventually become unusable. Therefore, start the car periodically to recharge the battery.
