Eveready type Exell brand M504 15 volt Electronic and Photo application battery. Single battery. Alkaline chemistry. Length .63" x .59" width x 1.37" height. This is a cylinder, not the squarish shape of the original and wil not fit into the battery chamber of the Finco Model VM-30K; before you order make sure a cylinder of our dimensions will fit. Metric dimensions: Diameter 15.9 mm x height 34.9 mm. Eveready quit making this battery due to the decline in analogue test sets used by outside plant technicians and companies. Duracell never made this battery back when they were a battery company. This Eveready M504 battery was in the storeroom of every telephone work center in the USA and Canada for (in the old days) analogue test equipment especially the Tripplett 310A Volt Ohm Meter, one of the best and treasured by cognoscenti. High praise to Exell for bringing back the old Eveready-type batteries with such high quality control and engineering excellence.!
