Slow Charging of Transmitter Ni-Cad Batteries
• Transmitter Ni-Cad batteries can be slow charged by the TX-Output
and the transmitter’s charging socket.
Quick Charging of Transmitter Ni-Cad Batteries
• Always take the transmitter battery out of the transmitter when using
the quick charge mode.
In case of defects the transmitter might be damaged by heat or
battery acid.
• Don’t quick charge by the transmitter’s charge socket.
The transmitter electronic could be damaged by too high charging
currents (>1A).
The charge stop automatic of the QUADRA-CHARGER could be
misled by the transmitter electronic.
• Therefor connect transmitter batteries always direct to the QUADRA-
CHARGER.
Memory Effect
The Memory Effect is a physical phenomenon. Ni-Cad batteries have a
kind of memory. The way a Ni-Cad is stored, charged and discharged
has a massive influence on its power output and capacity.
• If you charge a only half discharged Ni-Cad its power and capacity will
be less than if it was completely discharged before.
Therefor discharge Ni-Cads completely once in a while. RC-Power Ni-
Cads should be discharged after every use.
• A Ni-Cad has more power if it was charged shortly before use. For
best RC performance a Ni-Cad should be warm.
• Only RC-Power Ni-Cads: a Ni-Cad has its best power output when
being charged with a high charge current (see page 6).
For best RC performance a Ni-Cad should be warm before use.
Please pay attention to the battery manufacturer’s recommendations
to avoid over load.
• TX, RX and similar Ni-Cads are normally charged with a low current.

Battery Maintenance
• Follow the instructions of the battery manufacturer.
• For best results and life time we recommend to discharge RC-Power
Ni-Cad batteries completely after use with the QUADRA-CHARGER.
Discharge
Improve the fitness of your RC-Power Ni-Cads and avoid the Memory
Effect by discharging them after every use. RX, TX and similar Ni-Cads
should be discharged once in a while to prevent the Memory Effect.
• Connect the Ni-Cad to the POWER-Output.
• Select DISCHARGE with the MODE SELECT-Button.
• Push the red START-Button.
• The discharge with 3-4 Ampere starts.
• The DISCHARGE-LED flashes red, the cooling fan is working.
• When the Ni-Cad is discharged down to 0.5V/cell, the process is
automatically stopped. A triple peep tone is heard.
The QUADRA-CHARGER recognizes how many cells are connected
and stops automatically the discharge at 0.5V/cell .
• The DISCHARGE-LED is now green. Repeated peep tones indicate
that the discharge is finished, the battery can be disconnected.
• The discharge can be stopped and restarted with the START/ STOP-
Button at any time.
• The V-PEAK-Display shows and stores the lowest reached voltage.
• The %-CHARGE-Display starts with 100% and drops to 0% at the
end.

REFRESH 1
After some time Ni-Cad batteries should be treated with the
REFRESH 1 process. Especially Ni-Cads that were stored in a charged
condition for a longer period of time will regain most of their old strength.
The Memory Effect will be overcome.
The battery passes an automatic CHARGE-DISCHARGE-Cycle.
• Connect the Ni-Cad to the POWER-Output.
• Adjust a quick charge current (see page 6).
• Select REFRESH 1 with the MODE SELECT-Button.
• Push the red START-Button.
• The REFRESH 1-LED flashes red.
1. BASIC DISCHARGE
If some capacity is still left, the Ni-Cad will first be discharged.
The DISCHARGE-LED is red – the REFRESH 1-LED flashes red.
2. PRE-CHARGE
The Ni-Cad will be pre-charged with 0.15A for 2 minutes.
The CHARGE LED is red – the REFRESH 1-LED flashes red.
3. QUICK CHARGE
The Ni-Cad will be quick charged with the adjusted current.
The CHARGE LED is red – the REFRESH 1-LED flashes red.
4. DISCHARGE – The Ni-Cad will be discharged with 4A.
The DISCHARGE-LED is red – the REFRESH 1-LED flashes red.
5. CYCLE-END
After the complete cycle is finished, the REFRESH 1-LED is green.
The charger indicates with repeated triple peep tones that the Ni-Cad
is completely discharged and can be disconnected.
• The start of every single step is indicated by a peep tone.
• The REFRESH-Function can be stopped anytime with the START/
STOP-Button. Beginning with the BASIC DISCHARGE the
REFRESH-Function can be started again from the beginning by
pushing the START/STOP-Button a second time.

REFRESH 2
Use REFRESH 2 when a Ni-Cad is loosing its performance and
DISCHARGE or REFRESH 1 don’t bring any improvement. Chemical
changes of older Ni-Cads can be regenerated within certain limits.
The battery passes automatically 3 CHARGE-DISCHARGE-Cycles.
1. Select REFRESH 2.
2. Start the function same as REFRESH 1 (Connection/Charge Current).
3. Cycle 2 starts automatically after Cycle 1.
4. Cycle 2, the REFRESH 2-LED flashes twice.
Same function like Cycle 1, pre-charge, charge, discharge.
5. Cycle 3, the REFRESH 2-LED flashes three times.
The functions pre-charge, charge, discharge will run down a 3
rd
time.
6. End REFRESH 2
After cycle 3 is finished, the REFRESH 2-LED is green.
The charger indicates with repeated triple peep tones that the Ni-Cad
is completely discharged and can be disconnected.
• The start of every single step is indicated by a peep tone.
• The REFRESH-Function can be stopped anytime with the START/
STOP-Button. Beginning with the BASIC DISCHARGE of Cycle 1 the
REFRESH-Function can be started again from the beginning by
pushing the START/STOP-Button a second time.
Trouble Shooting Guide
• Short Circuit at the POWER-Output:
Charger peeps, makes noises – unplug, use only isolated connectors.
• Reverse Polarity at the POWER-Output:
No function, the LED’s are not flashing - unplug immediately, use only
polarity proof connectors.
Displays: V-Battery = 0, V-PEAK = 0, V-Input = 11-15V.
• Mains or 12V supply interrupted: Function-LED’s are not flashing.
Displays: V-Battery = 0, %-Charge = 0, V-Input < 10V.
• Temperature Protection activated:
Functions-LED’s stop to flash and start to light continuously red.
• Internal fuse between the 2 panels broken:
No function, let exchange by an expert, charger can be broken.
