Methods and system for alerting for a low battery state of charge for an autonomous compartments cluster interacting locally with a mobile device via a short distance wireless communication, the autonomous compartments cluster comprising: at least one compartment equipped with a door and an actuator for unlocking the door, a locker module controlling the actuator, and a battery pack powering the locker module and the at least one compartment, characterized in that the locker module comprises a voltage comparator comparing an output voltage provided at the terminal of the battery pack with a reference minimal voltage wherein the voltage comparator is configured to trigger an alert signal for replacing the battery pack when a minimum transitory voltage at the terminals of the battery pack resulting from an energizing of the actuator by a first step-up converter during an unlocking initiation of the door is lower than the reference minimal voltage, and wherein a controller is configured to change a battery status stored in a memory of the locker module from a usable battery status to a low battery status.
