  DESIGN FEATURES An Accurate Battery Gas Gauge
  by James Herr Introduction
  A battery fuel gauge can be implemented in a variety of ways. The
  most popular is to derive the remaining battery capacity from the battery
  voltage. This method has advantages
  in that it is easy to implement and
  relatively low in cost, but it does have
  one major drawback: It is relatively
  inaccurate. Battery voltage has, at
  best, an inconsistent relationship
  to battery capacity—the relationship
  varies greatly depending on battery
  discharge rate and temperature.
  The latest portable devices, though,
  require more accurate battery gas
  gauging. For instance, a portable
  computer or PDA may need to save
  data, or state information, and shut
  down when the battery reaches a
  critical discharge point. Accurate
  prediction of this point allows the
  device to safely run longer on battery
  power. For applications that require …
