The utility model discloses a special-purpose meter for measuring terminal voltage of a storage battery, comprising an organic-glass support plate. A voltage meter head is fixedly arranged on the organic-glass support plate, wherein the voltage meter head is respectively connected with tail ends of two bending meter pens via two meter pen wires; the bending meter pens are fixedly arranged on the organic-glass support plate, and an adjustable meter pen rotating device is arranged in the tail end of each bending meter pen; a hand-held hole type handle is arranged in the upper end of the organic-glass support plate; and a bending bare nib is arranged in the front end of each bending meter pen to contact with a pole column of the storage battery. The special-purpose meter of the utility model can conveniently realize single-person single-hand measurement of terminal voltage of the storage battery; and compared with traditional double-people measurement via a universal meter, the special-purpose meter is simple and reasonable in design, flexible and convenient in number reading in using process, being suitable for daily measurement and maintenance of storage battery groups in different voltage levels of transformer stations, power plants and factories, being able to effectively save time and labor force, and improving working efficiency.
