12. NIMH AND NICD RECHARGEABLE BATTERIES
a) General
The rechargeable battery programmes for NiMH and NiCd rechargeable batteries generally differ only in the inter-
nally 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 "ESC/MODE/STOP" or "DEC" (NiMH or NiCd), see
figures on the right.
Confirm the selection by pressing the "START/ENTER" button.
Then use the button "INC" or "DEC" to select the different rechargeable
battery programmes:
• "CHARGE Man": Charge rechargeable battery, set charging current manually
• "CHARGE Aut": Charge rechargeable battery, automatically select charging current
• "DISCHARGE": Discharging the rechargeable battery
• "CYCLE": Multiple charging/discharging or discharging/charging cycles
You can return to the main menu using the "ESC/MODE/STOP" button.
b) Charging Rechargeable Batteries ("CHARGE Man")
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 recharge-
able 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.
