ABSTRACT:
A battery backup installation for a time of use register for an electric meter is mounted within a case of the electric meter. The case includes a hatch which permits removal and replacement of the battery without requiring removal of the case from the meter. In one embodiment, the battery is installed in a battery clip on the face plate of the meter where it is accessible through the hatch. An extra length of wires from the battery permits the battery, and its mating connectors, to be withdrawn through the hatch for replacement thereof. In a second embodiment of the invention, the battery is captured in a door of the hatch and is withdrawn from the meter by the action of opening the hatch. In this embodiment, the hatch may be hinged or not hinged. Battery replacement is facilitated while the electronic register module is separated from line-supplied power. An auxiliary battery provides an auxiliary source of backup power during batterychange.
