b) Charging batteries ("CHARGE")

The charging current to be set depends on the rechargeable battery's capacity and is usually
1C (also see chapter 7). High-quality rechargeable batteries also can stand a charging current
up to 2C. However, you should always observe the battery manufacturer's instructions.
The value "1C" means that the charging current is equivalent to the battery's capacity.
A charge current of 3 A therefore must be set for a 3000 mAh-NiMH battery at 1C.
A value of 0.5C means that the charging current corresponds to half the capacity value.
At a NiMH rechargeable battery with a capacity of 3000 mAh, 0.5C means that a charg-
ing current of 1.5 A must be set.
In general: The smaller the battery (the individual cell), the lower the maximum charging
current.
For example, conventional NiMH-mignon/AA-cells with a capacity of 2000 mAh permit a
charging current of 1C (this corresponds to a charging current of 2 A). For quick charg-
ing of such cells (contained, e.g., in receiver batteries), never set more than 0.5C.
Charge a NiMH or NiCd battery as follows:
• First select the rechargeable battery type in
the main menu, as described in chapter
11. a) (NiMH or NiCd).
• Select the cell number in "CELLS" with the
buttons "-" and "+".
• Push the button ">" in "MODE" repeatedly
until the mode "CHARGE" is displayed.
• For "CURRENT", use the buttons "-" and "+"
to set the charge current. Keep the respective
button pressed for quick adjustment.
