The programmed data are stored to memory to be used in the battery discharge process.        
Tapping the Enter button causes the charger to initiate the preliminary steps, including 
a check of the balance connector, discharge mode, number of cells, and the delay time 
setup. The discharge process starts immediately after these preliminary steps. With proper 
programming, the charger will display a 5-second countdown. The discharging sequence 
is shown below.

LiPo, Lilon, LiFe, NiCd, NiMH  battery discharge processes

The charger checks for a connection with the balance 
board.
This process is automatic.

The discharge mode and the delay time are programmed. 
Tap  the  box  to  activate  (blue).  Tap  the  DEC/INC  button  to 
select the desired mode. The discharge modes are explained 
below.

Discharge mode selection

After  counting  down,  the  charger  initiates  the  discharge 
process. Tapping the Enter button            will cause 
the charger to immediately initiate the          discharge 
process.

The  delay  time  can  be  programmed  to  values  between 
1-150 minutes. After this preset time, the charger will then 
initiate the battery discharge process.

Delay time setup

Discharge mode per battery type

[ AUTOMATIC ]
- In this discharge mode, the discharge process proceeds automatically. The first two steps in-
clude checking the number of cells and determining the discharge current. The charger then calculates the 
internal resistance and discharge current for every period of time. The programming automatically adjusts the 
discharge current to ensure that the optimal discharge current is delivered to your pack. 
- Cutoff voltages (NiCd=0.9V/cell, NiMH=0.8V/cell, LiIon/Po=3.0V/cell, LiFe=2.5V/cell, Pb=1.8V/cell) are
applied (Charging the Lithium and Pb batteries after discharging does not affect the battery performances.)
- The preset CUT-TEMP is used in this discharge mode.

[ NORMAL ]
  - 

The charger will stop the discharging process every minute to calculate the average resistance.

[ LINEAR ]
  - 

The charger will discharge the pack, stopping once after 3 minutes to calculate the internal resistance. 

Discharge mode for the POLARON EX CHARGER

LiPo, LiIon, LiFe 

NiCd, NiMH, Pb

NORMAL  : Normal discharge. 
LINEAR   : The preset current is maintained throughout the discharge process.
LINK      : The packs with the same number of cells and capacity can be   
            discharged simultaneously.

AUTO     : The charger will automatically adjust the discharging conditions.
NORMAL  : Normal discharge process.
LINEAR    : The preset current is maintained throughout the discharge process.

In the LINK mode, the packs should have the same voltage, capacity and number of 
cells. Differences in these charging parameters can cause damage to the batteries. 

* Please install the balance cable to CH1, CH2.

This page (left) shows the battery check process with the 
balancer connected to the charger.
Tapping the Enter button         will access the next page
and cause the charger            to automatically initiate 
the charge process. 

After connecting the balance board, the charger can then 
check the number of cells. If the number of cells is
incorrect, tap the ESC button to return to the previous page 
and re-check the parameters. With the correct number of 
cells, the next page will automatically be accessed.
To initiate without a balance board, the number of cells 
should be determined and manually entered. After tapping 
the Enter button, the charger will then immediately initiate 
the discharge process.
