What is the normal sleep current for a Mercedes-Benz S350?
1 Answers
Mercedes-Benz S350 normal sleep current should not exceed 20.0mA. Introduction to sleep current: Sleep current refers to the weak current that still exists when the ignition switch is in the off position. It is precisely because of these sleep currents, along with the natural discharge of the battery, that vehicles are prone to being unable to start due to insufficient battery power after long-term parking. Reasons for sleep current: The existence of sleep current is because some control units must maintain power supply to preserve data memory functions. For example, the audio system needs to remember the last listened frequency band, the air conditioning system needs to remember the air direction and speed settings, and some sensors of the anti-theft system also require continuous power supply to ensure 24/7 monitoring functionality. This portion of sleep current discharge is considered normal external discharge for the battery.
