d) Discharging Rechargeable Batteries ("DCHG")
Normally, it is not necessary to discharge lithium batteries (contrary to NiCd batteries) before charging. The battery
can be charged immediately, independent of its current status. If you want to discharge a rechargeable lithium battery
anyway, you can set the discharge current.
The maximum possible discharging current depends on the battery type, battery capacity and number of
cells. The max. discharge output of the charger is 15 W for each channel. This limits the max. possible
discharge current of rechargeable batteries with multiple cells.
Discharge a lithium rechargeable battery only to the minimum permitted voltage per cell (see table in
chapter 7 or observe information of the rechargeable battery manufacturer). If the rechargeable battery is
discharged any further, this deep discharge will permanently damage it and render it useless!
• First, choose the rechargeable battery type with the button "BATT TYPE./STOP" or "DEC" as described in chapter
11. a) (LiPo, LiIon, LiFe or LiHV) and push the button "START/ENTER".
• Select the rechargeable battery programme "DCHG" with the button "INC"
or "DEC".
The upper left shows the rechargeable battery type, the upper right the
discharge end voltage per cell.
The lower left shows the currently set discharge current; the lower right shows the cell number ("3S") and the
associated total rechargeable battery voltage after discharge (cell number x discharge end voltage per cell).
Use the button "INC" or "DEC" to select a different rechargeable battery programme; use the button "BATT
TYPE./STOP" to return to the main menu.
• If the values need to be changed, push the "START/ENTER" button. The discharging end voltage per cell ashes.
Set this voltage with the button "INC" or "DEC". Keep the respective button pressed for quick adjustment.
The discharge end voltage set here applies per cell. The total voltage of the connected rechargeable bat-
tery is automatically calculated after setting the cell number (see below) and displayed at the lower right of
the display.
Conrm the discharging end voltage by pressing the "START/ENTER" button.
• The discharge current at the lower left of the display ashes. Change the discharging current using the button "INC"
or "DEC". Keep the respective button pressed for quick adjustment.
The maximum possible discharging current depends on the battery type and number of cells. The max.
discharge output of the charger is 15 W for each channel and thus limits the discharging current.
Conrm the discharging current with the "START/ENTER" button.
• The number of the cells in the lower right of the display ashes. Set the number of the cells with the button "INC" or
"DEC". Keep the respective button pressed for quick adjustment.
Depending on the cell number and the discharge end voltage set per cell (see above), the total voltage of
the connected rechargeable battery is calculated automatically (at the end of the discharge process) (for a
two-cell Lithium rechargeable battery, e.g., 6.0 V).
Conrm the cell number with the "START/ENTER" button; the display stops ashing.
• When no display is ashing anymore, keep the "START/ENTER" button pushed (approx. 3 seconds), to start
discharging.
