2. DISCHARGE

Useful for analyzing the remaining amount of electric charge stored in the battery. 

Insert a battery into slot.

1)

Press          to select DISCHARGE mode;

2)

Press          to select discharge current (100, 250, 350, 500, 650mA), 

Press CURRENT

After setting, the interface will stop flashing and DISCHARGE will initiate automatically 8 seconds later. 

Once the process is initiated, no other operations, like mode change, current selection etc. will be accepted. 
Users, however, can click            to check the battery real-time parameters like current, voltage, discharge 
capacity,  internal resistance and elapsed time.

Displays End when the 
DISCHARGE process has finished.

3. REFRESH

After setting, the process will initiate automatically 8 seconds later. It will stop flashing and enter into CHARGE
process.

First  charges  the  battery,  rest  for  one  hour,  discharges

,

rest,  then  recharges  again.

This  function  reduces  the 

memory  effect  and  re-activates  rechargeable  batteries  that  have  been  unused  for  a  long  period  of  time.  Also

useful when the battery capacity needs to be determined.

What  is  memory  effect:  It  describes  the  situation  in  which  rechargeable  batteries  gradually  lose  their  maximum 
energy capacity if they are repeatedly recharged after being only partially discharged. REFRESH may bring the 
rechargeable battery back to optimum condition.

When the CHARGE process finishes, the slot will rest for an hour 
and displays as shown on the right:

Rests for another hour after the DISCHARGE process has 
finished. Displays as shown on the right:

Insert a battery into slot.

1)

Press          to select REFRESH mode;

2)

Press          to select charge current (200, 500, 700, 1000, 1500mA). 
Discharge current will be half of charging current selected. 

Once the process is initiated, no other operations, like mode change, current selection etc. will be accepted. 
Users, however, can click            to check the battery real-time parameters like current, voltage, charge 
capacity,  internal resistance and elapsed time.

CAUTION

The charger is restricted to charging NiMH rechargeable battery only.

Never  adapt  this  charger  to  other  types  of  batteries  such  as  alkaline, 
lithium, carbon zinc.

Never charge or discharge any battery having evidence of leakage or damage.

Do not expose the device to direct sunlight, heating devices, open flames; avoid extreme high or extreme low 
ambient temperatures and sudden temperature changes.

Operate  on  a  hard  flat  nice  clean  smooth  heat-resistant  noninflammable  nonconductive  surface  in  a  well-
ventilated area. Never place the device on a carpet, or similar. 

Keep all the inflammable volatile substances away from operating area.

Avoid mechanical vibration or shock as these may cause damage to the device.

Do not short-circuit slots or other parts of the device. Do not allow metal wires or other conductive material into 
the charger.
