A system for managing a battery removal from an electronic device is provided. The electronic device includes a battery interface including multiple battery coupling contacts that engage with battery contacts of the battery in an installed position of the battery. A battery removal detector is configured to detect, based on signals received via the battery interface, an ongoing battery removal process during which first battery contact(s) are disconnected from corresponding first interface contact(s) while second battery contact(s) remain connected with second battery coupling contact(s), and in response, to output a battery removal signal. The system also includes a controller that receives the battery removal signal and, still during the battery removal process, controls a memory device of the electronic device to prevent or complete a defined operation (e.g., writing of persistent storage keys) prior to completion of the battery removal process, to thereby prevent a corruption of the memory device.
