The maximum possible discharging current depends on the battery type and number of cells.
The maximum discharging power is 10 W. This limits the maximum possible discharging
current for batteries with multiple cells.
Discharge a lithium battery only up to the minimum permissible end-point voltage per cell (note
the information provided by the battery manufacturer). If the battery were to be discharged
further, this deep discharge would lead to permanent damage and the battery would become
unusable.

The display shows the value of the discharging current
in the second row on the left. It must not exceed 1C.
The voltage value on the right must not be lower than
the voltage recommended by the manufacturer so as to
prevent excess discharge.
After setting the current and voltage, press and hold the

for more than 3 seconds to
start the charging process.
This display shows the number of cells that you have
set. The charger detects the number of cells in the
connected battery and displays them.
R = Number of cells detected by the charger
S = Number of cells that you have set
If both entries are identical, you can start charging.
If this does not apply, press the

button

to return to the previous menu. Check the set
number of cells again and correct it, if necessary.
This display shows the status during the charging
process in real time. Press the
STOP BATT/PROG
button once to stop an ongoing discharging process.
b) Programme for lead-acid batteries
Lead-acid batteries are completely different to lithium, NiMH and NiCd batteries. When
compared to their high capacity, they can only provide low currents. The charging process
is also different. The charging current for modern lead batteries must not exceed 0.4C. The
optimal charging current is 1/10C. The optimum charging current should, therefore, be approx.
1/10 of the capacity of the battery.
A higher charging current is not permitted as this would overload the battery. This
not only poses a risk of explosion and fire, but also a risk of injury due to the acid
contained.
Always observe the specifications printed on the battery and the manufacturer's
specifications, in particular regarding the charging current.
Lead-acid batteries cannot be charged using the fast charging programme. Observe
the information provided by the battery manufacturer.
Charging lead-acid batteries ‘Pb CHARGE’
This programme is only to be used for charging lead-acid batteries with rated voltages of 6 to
12 V. The charging current to be set depends on the capacity of the battery and should usually
be 0.1C. High-quality lead batteries can also tolerate a charging current of up to 0.4C. However,
you should always observe the battery manufacturer’s instructions.
The value ‘0.1C’ means that the charging current is equivalent 1/10 of the capacity
of the battery. For a lead battery with a capacity of 5000 mAh (= 5 Ah), a charging
current of 0.5 A must be set at 0.1C.

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’ and ‘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 ca-
pacity 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.

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 not become damaged by an excessive
charging current. Some batteries with lower internal resistance and lower capacity can
tolerate higher currents in automatic charging mode.
Depending on the battery and its internal resistance, the charging time for ‘NiMH Auto
CHARGE’ may be shorter than for the "CHARGE’ battery programme.
A significant difference over other methods 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.
