12. NiMH and NiCd Rechargeable Batteries
a) General
The rechargeable battery programmes for NiMH and NiCd rechargeable batteries generally differ only in the internally
used charging procedures. The settings in the menus are the same.
The charger must be in the main menu.
Select the rechargeable battery type matching the rechargeable battery used
here with the button "INC." or "DEC." (NiMH or NiCd), see gures on the right.
Conrm the selection by pressing the "START/ENTER" button.
Then use the button "INC." or "DEC." to select the different rechargeable bat-
tery programmes:
• "CHARGE": Charge rechargeable battery
• "Auto CHARGE": Charge rechargeable battery, automatically select charg-
ing current
• "DISCHARGE": Discharging the rechargeable battery
• "RE-PEAK": Re-charge a full rechargeable battery
• "CYCLE": Multiple charging/discharging or discharging/charging cycles
You can return to the main menu using the "BATT. TYPE/STOP" button.
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 charging current
of 3 A therefore is required 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 re-
chargeable battery with a capacity of 3000 mAh, 0.5C means that a charging current of 1.5 A must be set.
In general: The smaller the rechargeable battery (the individual cell), the lower the maximum charging cur-
rent.
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 charging of such cells (contained, e.g., in
receiver batteries), never set more than 0.5C.
Charge a NiMH or NiCd battery as follows:
• First, choose the rechargeable battery type with the buttons "INC." and "DEC." as described in chapter 12. a) (NiMH
or NiCd) and push the button "START/ENTER".
• Select the corresponding rechargeable battery programme "CHARGE" with
the buttons "INC." or "DEC.".
The value at the lower right represents the currently set charging current.
