11. NiMH and NiCd Batteries
You can view the entire menu structure in the correct order on the fold-out page. Here
the key functions for operating are also given.
a) Charging batteries ("CHARGE")
The charge current to be set depends on the battery capacity and is usually 1C. However, you should
observe the battery manufacturer's instructions.
The value "1C" means that the charge current is equivalent to the battery's capacity.
As such, a charge current of 3.0A should be set for a 3000mAh NiMH battery at 1C.
Depending on the battery connected and its structure, a charge current of 1C may not be
possible. For example, receiver batteries usually consist of Mignon/AA cells that cannot
withstand such a high charge current without incurring damage.
In general: The smaller the battery (i.e. the individual cell), the lower the maximum charge
current. Many NiMH Mignon/AA cells with a capacity of approx. 2000mAh allow a charge
current of 400-500mA for a fast charge.
Charge a NiMH or NiCd battery as follows:
• In the main menu, select the "NiMH" or "NiCd" charge program with the button "BATT. TYPE/STOP".
• Press the button "START/ENTER"; the display shows the following, for example:
The left image shows the manual mode (you specify the charge current), the right image the automatic
mode (the charger sets the charge current, all you specify is the top limit).
If you now briefly press the button "INC" or "DEC", you access the discharge program
("DISCHARGE"), then the cycle program ("CYCLE") and return to the charge program
("CHARGE"), see chapter 11. b) and 11. c).
• Briefly press the button "START/ENTER" to access setup mode. Now the current value blinks on the
bottom right of the display.
