select the desired slot and then press 

MODE

 or 

DISPLAY

 to change the mode. 

 
The charging current can be adjusted between 50, 75, 100, 150 and 200 mA. 
 

NOTE:

  When a high impedance battery  (over 2500 milliohm) is loaded onto the charger, due to its 

high  internal  impedance,  the  displayed  charging  current  may  be  much  less  than  your  pre-selected 
charging current. When this occurs, it does not indicate the charger is defective. It does require longer 
charging times.

Operational Modes 

1.

 

Charge  Mode.

  The  rechargeable  battery  is  charged  up  to  its  maximum  capacity.  The 

maximum capacity depends on the battery. For NiMh, it is 10V. 
 

2.

 

Discharge  Mode. 

The  discharge  mode  is  used  to  reduce  the  “memory  effect”.  The 

rechargeable battery is discharged to a preset battery voltage (6V). 
 
Once the discharge is finished, the total accumulated discharging capacity is displayed in the   
mAh  display  mode,  showing  how  much  energy  was  discharged  from  the  battery,  which  is 
referred to as the accumulated discharging capacity.   
 
No trickle charge current will be applied after discharge cycle is finished. 
 
The default discharge current is 75mA, and can be adjusted between 50, 75, 100, 150 and 200 
mA. 
 

3.

 

Refresh Mode. 

A rechargeable battery is charged and discharged repeatedly to optimize to its 

maximum  capacity.  Old  rechargeable  batteries  or  rechargeable  batteries  that  have  not  been
