ABSTRACT: "Device for signalling a specific charge condition of an accumulator battery". A device is described for signalling a specific charge condition of an accumulator battery (B), which device comprises a comparator circuit (C) for comparing the battery voltage (VB) with a reference voltage, a switching circuit (G2, G13) controlled by the comparator circuit and an indicator (L1, L2, L3) controlled by the switching circuit. The device comprises a memory cir- cuit (FF) which ensures that the indicator remains ener- gized for at least a specific time interval after the apparatus has been switched off.
