Nimh And Nicd Batteries; A) Charging Batteries ("Charge") - VOLTCRAFT B6 Duo Bedienungsanleitung

12. NIMH AND NICD BATTERIES

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 3.0 A should be set for a 3000 mAh 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 2000 mAh allow a
charge current of 400-500 mA for a rapid recharge.
Charge a NiMH or NiCd battery as follows:
• In the main menu, select the "NiMH" or "NiCd" charge program with the button "TYPE/
STOP".

• Press the button "ENTER/START"; the display shows, e.g., the following:

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 "+" or "-", you access the discharge program
("DISCHARGE"), then the cycle program ("CYCLE") and return to the charge
program ("CHARGE"), see chapter 12. b) and 12. c).
• Briefly press the button "ENTER/START" to access setup mode. Now the current value
flashes on the bottom right of the display.
