e) Discharging Battery („DISCHARGE“)
To put partially charged NiMH/NiCd rechargeable batteries into a defined starting condition, they can be discharged
with this rechargeable battery programme.
Specifically NiCd rechargeable batteries should not be recharged from a partially discharged condition, since the
capacity may reduce by this (memory effect).
The rechargeable battery can also be used to measure the capacity of rechargeable batteries.
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 NiMH or NiCd battery as follows:
• Set the rechargeable battery type as described in chapter 12. a) (NiMH or
NiCd) and select the rechargeable battery programme „DISCHARGE“.
The set rechargeable battery type is shown in the upper left of the display,
and the rechargeable battery programme next to it. The value in the lower
left indicates the currently set discharging current; the value on the right
represents the deactivation voltage.
Use the buttons „INC“ and „DEC“ to select a different rechargeable battery programme; use the button
„BATT.TYPE/STOP“ to return to the main menu.
• If the value for the discharging current and the deactivation voltage is to be changed, briefly push the button
„START/ENTER“. The discharging current flashes.
• Set the discharging current with the buttons „INC“ and „DEC“. Keep the respective button pressed for quick adjust -
ment.
• Briefly push the „START/ENTER“ button; the deactivation voltage flashes.
• Set the discharging current with the buttons „INC“ and „DEC“. Keep the respective button pressed for quick adjust
-
ment.
• Briefly push the „START/ENTER“ button to confirm the setting. The display stops flashing.
Proceed as described above to change the discharging current or the discharging voltage again if desired.
• To begin the discharge process, keep the „START/ENTER“ button pressed for longer (approx. 3 seconds).
If the settings are wrong, or if the charger detects a problem, an audio signal is emitted and the appropriate
information is shown in the display. You can stop the warning signal by pressing the „BATT.TYPE/STOP“
button. The charger then returns to the previous configuration menu.
The display shows, e.g., the following data while discharging:
The rechargeable battery type is shown in the upper left of the display
(„NiMH“ = NiMH rechargeable battery), the upper middle shows the
discharging current and the upper right the current rechargeable battery
voltage.
The lower left shows the current rechargeable battery programme („DSC“ = „DISCHARGE“), the middle the
elapsed discharging time and the discharged capacity is mAh is displayed to the right of this.
• Once the discharging process has been completed, an audio signal is emitted (if it was not turned off).
If you wish to cancel the discharging process, push the „BATT.TYPE/STOP“ button.
