ABSTRACT:
A battery capacity indicating device includes a plurality of switching parts connected in parallel to a battery, each of which outputs a controlling signal corresponding to a predetermined voltage range when a voltage across the battery terminals falls within the predetermined voltage range, with at least one of the predetermined voltage ranges having finite upper and lower limits; a controlling part for receiving the output controlling signal among other controlling signals and generating from the received controlling signals a displaying signal corresponding to a display range into which the voltage falls; and a displaying part for generating a display indication representative of the display range. A battery capacity indicating method is provided wherein the displaying signals corresponding to the controlling signals are output when they are applied.
