Abstract

PURPOSE:To display separately specific gravity and liquid level of electrolyte by one circuit by connecting a liquid level sensor and a specific gravity sensor, provided inside a storage battery, to the terminal of the storage battery through a resistor and also to the anti-parallel circuit of a luminous diode. CONSTITUTION:The inside of the storage battery 1 is provided with the liquid level sensor 4 in a conductive state when contacting with the electrolyte 2 but in nonconductive state when not contacting with the electrolyte and also with the specific gravity sensor 5 in a conductive state when the specific gravity of the electrolyte 2 exceeds a fixed value but in nonconductive state when the specific gravity is below a fixed value. And, the liquid level sensor 4 and the specific gravity sensor 5 are connected to the terminal 3 of the storage battery 1 through respective resistors 6 and 7, and also between the sensor 4 and the sensor 5 is provided with the anti- parallel circuit of the luminous diodes 8 and 9 for connection.
