What Amount of Current is Considered a Leakage in Cars?

[McStephen]

For ordinary cars, a current exceeding 40mA is considered a leakage, while for high-end cars, it's over 80mA. Below is a detailed introduction about car current leakage: Reasons for normal leakage: Some electrical devices must remain powered to maintain data memory functions. These devices mainly include computer control units and anti-theft sensors, which require continuous power supply to ensure round-the-clock monitoring capabilities. All these factors contribute to the inherent current leakage in cars. Reasons for abnormal leakage: Short circuits or oxidation shedding of the battery plates leading to self-discharge and power loss, as well as electronic components and circuits grounding causing leakage and battery depletion, are the primary causes of abnormal leakage.
