12. NiMH and NiCd Rechargeable Batteries
a) General Information
The rechargeable battery programmes for NiMH and NiCd rechargeable batteries generally dif-
fer 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 re-
chargeable battery used here with the button "INC" or
"DEC", 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": Charge rechargeable battery
• "Auto CHARGE": Select the charge current according
to the rechargeable battery
• "DISCHARGE": Discharging the rechargeable battery
• "RE-PEAK": Repeat the charge end recognition
• "CYCLE": Perform multiple discharge/charge cycles
You can return to the main menu using the "BATT. TYPE/STOP" button.
b) Charging Rechargeable 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 rechargeable 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 current.
