A mobile environment-controlled unit having a structure, a compartment supported by the structure, and an environmental-control system in environmental communication with the compartment. The environmental-control system is configured to control an environmental parameter of the compartment. The environmental-control system includes an internal combustion engine, having a starter, powering the environmental-control system; a battery powering the starter; and a controller. The controller monitors battery health status, predicts battery failure, and communicates the predicted battery failure. Also, described is a method of operating the mobile environment-controlled unit and a controller for controlling the mobile environment-controlled unit.
