e) Discharging Battery ("DISCHARGE")
To put partially charged NiMH/NiCd rechargeable batteries into a dened starting condition, they can be discharged
with this rechargeable battery programme. Specically 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 battery type, battery capacity and number of
cells. The max. discharge output of the charger for channel 1 is 25 W, and for channels 2 and 3 it´s 10 W
each. This limits the max. possible discharge current for rechargeable batteries with multiple 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, briey push the "START/
ENTER" button. The discharging current ashes.
• Set the discharging current with the buttons "INC." and "DEC.". Keep the respective button pressed for quick
adjustment.
• Briey push the "START/ENTER" button; the deactivation voltage ashes.
• Set the discharging current with the buttons "INC." and "DEC.". Keep the respective button pressed for quick
adjustment.
• Briey push the "START/ENTER" button to conrm the setting. The display stops ashing.
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 conguration 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 dis-
charging current and the upper right the current rechargeable battery volt-
age.
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.
• 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.
