F) Discharging Battery („Discharge") - VOLTCRAFT Quadro B6 Bedienungsanleitung

f) Discharging Batteries („DISCHARGE")
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 such a lithium rechargeable battery anyway you can set the discharging current between
0.1 A and 2.0 A.
The maximum possible discharging current depends on the rechargeable battery type, rechargeable battery
capacity and cell number (the max. discharging output of the charger per channel is 10 W each, which limits
the max. possible discharging current for rechargeable batteries with several 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!
The procedure when setting the discharging current and voltage/cell number must be performed the same as when
charging, see chapter 11. b), except that the rechargeable battery is not charged, but discharged after starting the
rechargeable battery programme.
After starting the discharging process, various information about the current
progress is shown in the display.
In the upper left, the rechargeable battery type and the cell number are displayed („Li3S" = Lithium rechargeable
battery with 3 cells); the discharging current is shown in the upper middle and the current rechargeable battery volta-
ge in the upper right.
The lower left shows the current rechargeable battery programme („DSC" = „DISCHARGE"), in the middle the
elapsed charging time and the charged capacity in mAh are displayed to the right of this.
The final discharge voltage differs depending on the battery type and already present in the charger.
• LiPo: 3.0 V per cell
• LiIon: 2.9 V per cell
• LiFe: 2.6 V per cell
If a multi-cell battery is connected via the balancer connections, you can switch between the normal display
and the display of the cell voltages during the discharge process by repeatedly pressing the „INC" button.
