Will the car battery die if the car is parked for a month?

If a car is parked for a month, the battery will not die. The methods for maintaining a car battery are: 1. Regularly inspect and clean the exterior of the battery during use; 2. Minimize the use of in-car electrical appliances after turning off the engine; 3. Car batteries have a limited lifespan, so replace them periodically; 4. If the vehicle is not used for an extended period, start the car regularly. The functions of a car battery are: 1. To supply power to the starting system, ignition system, and electronic fuel injection system during engine startup; 2. To provide power to the car's electrical equipment when the engine is off or idling at low speed; 3. To act as a voltage stabilizer for the vehicle's electrical system; 4. To store excess electrical energy generated by the alternator.
Yes, the car battery is likely to run out of power if left parked for too long. Once when I was on a business trip for a month, I couldn't start the car when I returned. The car battery discharges itself every day, and even when the engine is off, the anti-theft system and computer modules still quietly consume power. After a full month, the battery is completely drained. In hot weather, the discharge rate is even faster, and an old battery might not last more than a few days. It's recommended to start the engine for 30 minutes each week to recharge the battery, or disconnect the negative terminal to reduce power loss. Don't be like my friend who left the car unused for over half a year, resulting in a dead battery and spending an extra thousand bucks on a new one. For cars that are unused for long periods, it's also important to check the parking environment—avoiding direct sunlight can slow down the discharge rate. Developing good habits can save you a lot of trouble.
