Will the car battery die if the car is not used for 20 days?

If the battery is fully charged and the car is in good condition before parking, it is acceptable not to use the car for 20 days. However, if the car is in poor condition and the battery is not fully charged, the battery may die after being parked for 20 days. Generally, if the car is not used for half a month, the battery may still have some power, but the voltage will have dropped, making it difficult to start. If the car is parked for more than three months, the battery will almost completely discharge. When parking the car, it is best to start it once a week to recharge the battery. Car batteries have a self-discharge characteristic. Even if the car is not used and parked, the battery will gradually discharge. Typically, a battery can fully discharge in three months. If the car is not used for an extended period, it is advisable to disconnect the battery. Some electrical components in the car do not stop working even when the engine is off, which over time can lead to battery depletion and even irreversible damage, significantly reducing the battery's lifespan. Precautions for long-term car parking include: It is best to store the car in a garage. If parked outdoors, cover the car with a car cover if possible, or at least park it in a shaded or covered area to avoid exposure to sunlight, rain, and damage from debris like fallen leaves to the car's paint. Do not engage the handbrake for long-term parking. For vehicles parked for extended periods, the brake system, being idle for a long time, can easily react chemically with water vapor and oxygen in the air, along with rainwater erosion. This can cause the brake discs and pads to rust to varying degrees, potentially leading to the wheels locking up if they stick together.
