Lipo, Lilon, Life, Nicd, Nimh, Batteries Discharge Processes; Discharge Mode Per Battery Type - GRAUPNER Polaron EX Operating Instructions Manual

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.
Discharge mode selection
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.
After counting down, the charger initiates the discharge
process. Tapping the Enter button
the charger to immediately initiate the
process.
Delay time setup
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.

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
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.

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.

Number of cells checking
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.
