Abstract: A drain detection system for a vehicle includes: a sensor configured to detect parameters of a low-voltage battery of the vehicle and collect battery data including the parameters when the vehicle is OFF; a telematics module; and a control module configured to i) receive the battery data from the sensor when the vehicle is ON, ii) transmit via the telematics module the battery data to a network device, which is remotely located from the vehicle, iii) receive an alert message from the network device indicative of a parasitic drain on the low-voltage battery, and iv) perform a first countermeasure in response to the alert message.
