I recently acquired a vintage Eico Model 232 Vacuum Tube Voltmeter (VTVM) from the 1950s. Upon opening the VTVM for first inspection, I noticed the battery pictured above installed. I am not familiar with the Bright Star brand of battery nor can I remember in my lifetime a D Cell ever being available for a nominal price of 20 cents. So I reach out to you, my many followers, on any information that you may have about this vintage battery. Believe it or not, it still has a charge and reads 1.1 Volt when measure by the Volt-Ohm-Meter!
