Will the car battery die if the car is not driven for a month?

Will the car battery die if the car is not driven for a month? The answer is yes. Here are the factors that affect battery discharge. Factors related to parking duration: The duration a battery can be left unused depends on its self-discharge rate. Due to inherent impurities in battery materials, power loss occurs whether the battery is in use or not. At room temperature, approximately 1% of charge is lost per day. When installed in a vehicle, the battery supplies current to maintain vehicle functions such as the central control computer and central door locks even when stationary. This standby current is referred to as "parasitic drain," and its magnitude varies depending on the vehicle's configuration. Other factors: High-end vehicles feature automatic wake-up functions. When activated by external influences, the current can reach several amperes and may take several minutes to return to sleep mode. The battery voltage level is not the sole determinant of whether the vehicle can start; it is also directly related to the vehicle's condition and ambient temperature.
