Abstract

PURPOSE:To display an unloaded storage battery voltage and a loaded storage battery voltage or a storage battery capacity, by separating a display part of a voltmeter having an enlarged scale into upper and lower display bands. CONSTITUTION:When a switch 3 is connected to one contact, a voltage measuring circuit consisting of a resistance 5, a constant voltage element 4, and a light emitting diode 7 is connected to a storage battery 1; and when the switch is connected to the other, a voltage measuring circuit consisting of the resistance 5, the constant voltage element 4, and a light emitting diode 8 and a load 2 are connected to the storage battery 1. In a display part 9 of a voltmeter 6, a display band 10 for unloaded case and a display band 11 for loaded case are provided. The specific gravity of the electrolyte, the storage battery voltage, the storage battery capacity calculated on a basis of the storage battery voltage value, etc. are displayed with different colors. Thus, the storage battery capacity, the specific gravity of the electrolyte, and the storage battery voltage for discharge are confirmed as a slight without error, thereby the storage battery is accurately monitored.
