What are the reasons for feeling the car battery is dead when starting the engine?

Reasons for feeling the car battery is dead when starting the engine: 1. The steering wheel is locked. If the steering wheel is not straightened when parking and has an angle greater than 30 degrees, it will automatically lock, acting as an anti-theft device for the car; 2. The gear is not in neutral or P position when parking; 3. Insufficient fuel. Check the fuel gauge to see if it is below the red line. If so, it indicates insufficient gasoline; 4. Check if antifreeze has been added. In winter, if antifreeze is not added, the water circuit may freeze, damaging other car components and preventing ignition, thus the car cannot start; 5. The car key battery is dead or low, causing the start system to fail to sense the current and preventing the car from starting.
Last time I had my car repaired, this happened often. It seems that a dead car battery is quite common. First, battery aging is the main reason. After three or four years of use, the battery's ability to hold a charge decreases, and it's more likely to die in cold winter weather. Second, a faulty alternator, which should charge the battery while driving, can fail and cause the battery to drain. Third, corroded or loose cable connections can prevent current from flowing. Fourth, leaving lights or electrical devices on can drain the battery overnight. Fifth, long-term inactivity can naturally deplete the battery, or a faulty voltage regulator can cause overcharging and damage. I recommend first checking the battery's age—if it's over three years, consider replacing it. Try charging it or measuring the voltage, regularly maintain and clean the connections, and add a protective cover before cold weather. Develop good habits to avoid unnecessary use of electrical devices—safe car usage is crucial.
