f) Discharging the battery ("DISCHARGE")
In general, it is not necessary to discharge lithium batteries before they are going to be charged (unlike the method
used with NiCd batteries). The battery can be charged regardless of its existing state. However, if you wish to
discharge a lithium battery, you can do so by adjusting the discharge current.
The maximum discharge current depends on the battery type, battery capacity and number of cells. The
max. discharge power of the charger is 80 W; this limits the max. possible discharge current in batteries with
multiple cells.
Discharge a lithium battery only to its minimum allowable voltage per cell (see table in Chapter 7 and
the battery manufacturer's instructions). If the battery is discharged further, the battery is permanently
damaged by this deep discharge and becomes useless!
If the charger is operated on a car lead-acid battery (rated voltage 12 V or 24 V), there is a special feature
when discharging.
In the system settings, you can turn on the "Regenerative Discharge".
In this case, the charger can charge the car lead-acid battery while discharging the lithium battery. The
energy of the lithium battery is not converted to heat during the discharge cycle, as in conventional chargers;
rather, it is fed back into the car lead-acid battery. This naturally comes with some losses.
The discharge in this mode can be set higher (depending on the battery, max. 10 A).
Don't use this function if the charger is connected to a power supply (and not to a car lead-acid battery)!
If the charger connected to a car lead-acid battery and if you have
enabled the "Regenerative Discharge" function, the display shows
"REGEN.DSC" instead of "DISCHARGE" when you select the
discharge program.
For more information, see Chapter 17.
The procedure for setting the discharge current and voltage or number of cells is carried out in the same way as
described under the battery program "CHARGE"; see Chapter 11. b) - with the difference that the battery will be
discharged and not recharged.
After discharging starts, various pieces of information about the current
progress appear in the display.
The battery type ("Li3S" = lithium battery with 3 cells) is shown at the top left,
the discharging current top centre and the current battery voltage top right.
Bottom left has the current battery program ("DSC" = discharging battery); the elapsed discharging time is in the
middle, and to the right is the discharge capacity in mAh.
If a multi-cell battery is connected via the balancer connections, you can toggle between the normal display
and the display of the cell voltages during the discharge process by repeatedly pressing the "INC" button.
The end discharge voltage differs by battery type and is already preset in the charger (LiPo = 3.0 V per cell,
LiIon = 2.9 V per cell, LiFe = 2.6 V per cell, LiHV = 3.1 V per cell).
