CONCEPTION AND MAIN APPLICATIONS
Multi voltage charger DC1804 is the renewed model of DC1803.
Its features and benefits are
(1) Approx. 10-20 minutes shorter charging time in comparing
with DC1801. See "Comparison of products:" on page 3/4.
(2) Maintenance (trickle) charging system keeps the full charged H
condition for 24 hours, even if the battery is left in this charger L
after finishing of charging process.
(3) Downsized ; The dimensions have been reduced to those of DC1413. Dimensions : mm ( " )

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