Nimh And Nicd Accumulators; Charging Accumulators ("Charge") - VOLTCRAFT B6 Notice D'emploi

12. NiMH and NiCd accumulators

a) Charging accumulators ("CHARGE")
The charge current to be set depends on the accumulator capacity and is usually 1C. However,
you should take the accumulator manufacturer's instructions into account.
The value "1C" means that the charging current is equivalent to the accumulator's capacity.
As such, a charge current of 3.0A should be set for a 3000mAh NiMH accumulator at 1C.

Depending on the accumulator 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 accumulator (i.e. the individual cell), the lower the
maximum charge current. Many NiMH mignon/AA cells with a capacity of
2000mAh allow a charge current of 400-500mA for a rapid recharge.
Charge a NiMH or NiCd accumulator 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 12. b) and 12. c).
• Briefly press the button "Start/Enter" to access setup mode. Now the current value blinks on
the bottom right of the display.
