CONCEPT AND MAIN APPLICATIONS
  Both of Ni.Cd and Ni.MH MAKITA batteries                                                                          H
  from 7.2V to 18V can be charged with this DC1803.
  Its features and benefits are
  (1) Approx. 10 - 20 minutes shorter charging time in comparing
      with DC1801.
  (2) Maintenance (trickle) charging system keeps the full charged
       condition for 24 hours, even if the battery is left in this charger
       after finishing of charging process.                                   W

  Ideal charging system in this class with the following installations
1 Controlling by micro computer : The installed micro computer perceives the full charged condition, and
                                  control the optimum way to stop the charging process, from the followings.
        A) Minus delta V system : Stop the charging process with perceiving the battery's voltage drop.
        B) Delta T system        : Stop the charging process with perceiving the change of battery's temperature.
                                    ( This system is applied to only the charger of 4 terminal-type.)
        C) T system (Timer)      : Stop the charging process with perceiving the battery's temperature which is
                                    input in the micro computer in advance. For instance the charging process is to
                                    be stopped at 45
