Zusammenfassung:The utility model relates to a battery status indicating circuit specifically is a novel battery stator indicator. The utility model provides a current battery stator indicator consumption big, instruct the not good problem of effect. A novel battery stator indicator, includes NPN type transistor, PNP type transistor, emitting diode, first resistance, second resistance, third resistance, fourth resistance, the 5th resistance, electric capacity, wherein, the base of NPN type transistor is connected through first resistance and positive supply end, and the base of NPN type transistor is passed through fourth resistance and is held with the negative supply and be connected, the collecting electrode of NPN type transistor passes through second resistance to be connected with the positive supply end, and the collecting electrode of NPN type transistor is connected with the base of PNP type transistor, the projecting pole of NPN type transistor is connected through the 5th resistance and negative supply end, the co
