c) Programmes for NiMH/NiCd batteries
The battery programmes for NiMH and NiCd batteries differ only in the charging process used
internally. The settings in the menus are the same.
Charging NiMH/NiCd batteries 'NiMH CHARGE' or 'NiCd CHARGE'
This programme is used for charging and discharging NiMH/NiCd batteries, which are typically
used in remote-controlled model vehicles. The charging current to be set depends on the
battery capacity and is usually 1C. High-quality batteries can also tolerate a charging current of
up to 2C. However, you should always observe the battery manufacturer's instructions.
'1C' means that the charging current is equivalent to the battery's capacity. As such,
a charging current of 3 A should be set for a 3000 mAh NiMH battery at 1C.
A value of 0.5C means that the charging current corresponds with half of the
capacity value. For a NiMH battery with a capacity of 3000 mAh, 0.5C means that a
charging current of 1.5 A should be set.
In general: The smaller the battery (i.e. the individual cell), the lower the maximum
charging current.
Select the desired battery programme for the battery type
(NiMH/NiCd) – 'NiMH CHARGE' or 'NiCd CHARGE'.
Press the STATUS + buttons (4) and (21) and STATUS
- buttons (5) and (18) to set the charging current values.

Charging NiMH/NiCd batteries in automatic charging mode 'NiMH/ NiCd Auto CHARGE'
This mode is intended for automatic charging of NiMH/NiCd batteries. In automatic
charging mode, the charger verifies the state of the connected battery (e.g. the internal
resistance) and uses this to calculate the charging current. You must set an upper limit
for the charging current so that the battery does become not damaged by an excessive
charging current. Some batteries with lower internal resistance and capacity can tolerate
higher current flows in automatic charging mode.
Depending on the battery and its internal resistance, the charging time for 'NiMH/NiCd Auto
CHARGE' may be shorter than for the 'CHARGE' battery programme.
The only difference is that it is not the actual charging current that is set, but a limit
value for the maximum charging current that the charger must not exceed for safety
reasons.
Select the desired battery type (NiMH/NiCd) and the
battery programme – 'NiMH Auto CHARGE' or 'NiCd Auto
CHARGE'.

Charging NiMH/NiCd batteries in re-peak charging mode (NiMH/NiCd RE-PEAK)
When working with NiMH and NiCd batteries, the charger automatically ends charging when
the battery is full. The delta U method is used to determine when a battery is fully charged. Re-
peak charging mode is only suitable for charging NiMH and NiCd batteries. The state of charge
can be redetermined using the 'RE-PEAK' battery programme. The charger then automatically
charges the battery several times (once, twice or a maximum of three times) in succession.
After each recharge, the charger waits for approx. 5 minutes to allow the battery to cool down.
This not only ensures that the battery is fully charged, but also allows you to verify how well the
battery withstands fast charging.
Start by charging a battery fully with the 'NiMH CHARGE' battery programme as normal. Only
then should you start the 'RE-PEAK' battery programme. Proceed as follows:
Select the desired battery programme for the battery type
(NiMH/NiCd) – 'NiMH RE-PEAK' or 'NiCd RE-PEAK'.

Discharging NiMH/NiCd batteries 'DISCHARGE'
This battery programme can be used to bring partially charged NiMH/NiCd batteries to a
defined initial state or to measure the battery capacity. NiCd batteries in particular should not
be recharged when partially charged as doing so can reduce their capacity (memory effect).
The maximum possible discharging current depends on the battery type and number
of cells. The maximum discharging power for a charging channel is 10 W. This limits
the maximum possible discharging current at the battery.
To discharge a NiMH or NiCd battery, proceed as follows:
Select the desired battery programme for the battery type
(NiMH/NiCd) – 'DISCHARGE'.
