C) Automatic Charge Mode ("Charge Aut"); D) Discharging Battery ("Discharge") - VOLTCRAFT V-Charge 200 Duo Operating Instructions Manual

c) Automatic Charge Mode ("CHARGE Aut")

In automatic charge mode, the charger checks the condition of the connected
rechargeable battery (e.g. the inner resistance) and calculates the charging
current from this. You need to set an upper limit for the charging current so
that the rechargeable battery is not damaged by a too-high charging current.
Depending on the rechargeable battery and its inner resistance, shorter charging times may be achieved in the re-
chargeable battery programme "CHARGE Aut" than in the rechargeable battery programme "CHARGE Man" (chapter
12. b).
Proceed as in the rechargeable battery programme "CHARGE Man" for setting and operation (chapter
12. b).
The only difference is that you do not set the actual charging current, but the limit for the maximum charging
current that the charger must not exceed for reasons of safety.

d) Discharging Battery ("DISCHARGE")

This rechargeable battery program can be used to put partially charged NiMH/NiCd rechargeable batteries into a
defined starting condition or to perform a measurement of the rechargeable battery capacity.
Specifically NiCd rechargeable batteries should not be recharged from a partially discharged condition, since the
capacity may reduce by this (memory effect).
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 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 (NiMH or NiCd) 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 lower right represents the
deactivation voltage at the end of the discharge process.
Use the buttons "INC" or "DEC" to select a different rechargeable battery programme; use the button "BATT
TYPE./STOP" to return to the main menu.
• To change the value for the discharging current and the deactivation voltage, briefly push the "START/ENTER"
button. The discharging current flashes.
• Set the discharging current with the buttons "INC" and "DEC". Keep the respective button pressed for quick adjust-
ment.
The maximum possible discharging current depends on the battery type and number of cells. The max.
discharging output of the charger is 15 W for each channel.
• Briefly push the "START/ENTER" button; the deactivation voltage flashes.
• Set the deactivation voltage with the buttons "INC" and "DEC". Keep the respective button pressed for quick
adjustment.
• Briefly push the "START/ENTER" button to confirm the setting.
Proceed as described above to change the discharging current or the discharging voltage again if desired.
