A portable optical code reader, in particular for bar codes (BC), having at least one supply battery (7); an electronic circuit (5) with a microprocessor (15); and optoelectronic lighting and receiving devices (10, 12) cooperating with the microprocessor (15) to read an optical code, in particular a bar code (BC). The microprocessor also estimates the charge of the battery (7) on the basis of the maximum charge storable in the battery, of measured recharge units supplied when recharging the battery, and of charge units estimated to have been consumed during operation of the reader. <IMAGE> <IMAGE> |
