Abstract
A backup power supply comprising a removably attachable battery that is configured to provide a backup power supply to an electrical appliance is disclosed herein. An electrical housing is configured to be mounted on the electrical appliance. A removably attachable battery is mounted on the electrical housing, which comprises a circuitry that includes a sensing device that is configured to detect primary power supply from a main power supply to the electrical appliance. A transfer switch is configured to select one of primary power supply provided by the main power supply or the backup power supply provided by removably attachable battery based on the sensing device deciding what is appropriate. A control circuitry is configured to control the transfer switch to engage the removably attachable battery in the circuitry when the sensing device fails to detect the primary power supply from the main power supply to the electrical appliance.
