What is the normal discharge level for a car?

[SanJuliet]

Different car brands have varying discharge currents. Vehicles with fewer electrical appliances tend to have lower discharge currents, while those with more electrical appliances exhibit higher discharge currents. After the engine is turned off, the car's sleep current typically ranges between 40 milliamperes and 80 milliamperes. Below are the daily power leakage of car batteries and methods for inspecting car discharge: Daily power leakage of car batteries: A car battery loses approximately 1% of its charge daily. If the battery remains connected to the car, it uses a minimum current (commonly referred to as "sleep" current) of about 80mA to maintain basic functions. If the car is equipped with an anti-theft alarm, additional power is consumed, generally resulting in a daily power loss of around 2% to 3%. Methods for inspecting car discharge: First, use a battery tester to check if the battery has aged. If the test results are normal and the battery discharge is due to human factors, simply recharge the battery. If the battery gradually depletes while the vehicle is in operation, first inspect the generator or charging system for any faults.
