     Description             Fast charger

  This fast charger can charge both Ni-MH battery
  (7.2V,9.6V) and Ni-Cd battery(7.2V,9.6V).
  Its brief benefits are;
  *Tricle charge function
  Tricle current flows after completion of charging
  to prevent self-discharging of battery and keep
  battery at fully charged condition.
  *Even a heated battery after use can be left in the charger.

  This charger automatically starts charging the battery

  after cooling down.                                                                              m

   The standard equipment for the tools shown may differ from country to country.

"Even if you insert a hot battery just after use,
it will start charging automatically
when the battery temperature becomes lower."

How to charge
    1. Computer control
       Computer deducts the completion of charging and controls charging current.
    2. Switching power source method
       First,input electricity is converted to high-frequency current of approximately
       one hundred kHz. And the voltage is transformed innto the battery voltages
       by the high-frequency transformer.
       The charger can be designed smaller and lighter than using the general transformer
       with this method.
    3. Constant current charging
       Charging current will be kept stable, so that the change of the battery
       can be detected.
       (See the "1. minus delta V" of Method of stop charging)
    4. Trickle charging function
Method of stop charging
  DC1801 has four different methods of stop charging.
  Each of methods will work individually.(whichever method comes first will stop charging.
  1. minus delta V
     Charging will be stopped by the detection of the drop of the battery voltage.
     See (1) of chart below.
  2. delta T
     Charging will be stopped by the detection of the rise of the battery temperature.
     See (3) of chart below. (for the batteries with 4 terminals only)
  3. T
     Charging will be stopped by the detection of the upper limit of the battery temperature.
     See (2) and (3) of chart below.
     The upper limits of the battery temperature are 45 degree C. for 1.3Ah batteries
     and 60 degree C. for 1.7, 2.0 and 2.2Ah batteries.
  4. Timer
     Charging will be stopped by the length of charging time as a supplementary method.
