Interior light left on for 20 hours will drain the battery. Lifespan of car battery: Generally, a car battery lasts about 3 years. Whether the car battery has power plays a decisive role in whether the car can start. If the battery is dead, the car will fail to start, and the battery needs to be charged at this time. In severe cases, the battery may even need to be replaced. The battery's ability to hold a charge decreases with the number of charge and discharge cycles. Precautions for using interior lights: The power consumption of car interior lights is relatively small. If forgotten to turn off, it takes about 20 hours to affect the battery and cause it to drain. Generally, after the car is turned off, the interior lights will also turn off. If they remain on, it may indicate that a door is not properly closed.
