(GB2346491-A)   NOVELTY - The back-up power source (52) is contained within fuse component (42) that is plugged into existing fuse block. The fuse component includes positive and ground prongs (54,55) connected to the poles of battery through leads (58,59), respectively. Power from fuse component is fed to real time clock via back-up power wire and a diode.    USE - For real-time clock of on-board device controller like engine control module of vehicle.    ADVANTAGE - Life span of back-up battery is increased. The fuse component includes a fuse casing made of moldable plastic to maintain environmental soundness of fuse component, to prevent leakage of encased back-up battery and to protect battery from external electric impulses or EMF.
