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 3rd 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.
