| description | A cordless device 11 comprises a load 13 and a multiple pack power supply 15 connected to load 13. A voltage detection circuit 23, 63, 64, 75, 76 is connected to supply 15 and detects when one of the batteries 17, 19 is charged and the other is discharged. Circuits 23, 63, 65, 75, 76 may also function as a voltage comparator circuit to identify when one of the batteries 17, 19 is defective. The detection or comparator circuit includes comparators 25, 33 for comparing the battery voltages. An indicator 41, 43, 65, 74, 81 is connected to the output of comparators 25, 33 and provides an end user identifiable signal responsive to the outputs of comparators 25, 33. |
