Your car battery level is indicated as ‘low’ in case the autoSense adapter registered a voltage drop below 11V at least twice within a 7 days time span. It will remain on ‘low’ until there are less than two voltage drops below 11V within 7 days. Then it will clear the status and set it back to ‘normal’. Please be aware that a voltage drop can be caused by various factors such as the use of indoor lights with a switched off engine, low outdoor temperatures etc.
In idle mode, standard electricity consumption of autoSense is 0.65 mA.
When the car battery is removed or out of charge, the device stops working as well
