What is the normal current for a car?

[LucilleLynn]

Car leakage current is normally below 40mA for ordinary vehicles and below 80mA for high-end vehicles. Here is some relevant information about car leakage: Introduction: Car leakage refers to the gradual discharge of the battery when the vehicle is parked, which can affect car starting or cause electrical malfunctions. Some cars have dark current, which falls within the normal leakage range. This is because certain electrical devices require continuous power supply to maintain data memory functions, such as audio systems and air conditioning. Some anti-theft sensors also need long-term power supply to ensure 24/7 monitoring. Car discharge troubleshooting methods: Use a battery tester to check if the battery is aging. If the test is normal and the battery discharge is caused by human factors, simply recharge the battery. If the battery gradually depletes during vehicle operation, first check if there is a fault in the generator or charging system.
