• To avoid short circuits between the banana plugs tted to the charge leads, please al-
ways connect the charge leads to the charger and only then to the battery! When disconnecting, proceed in reverse order.
• When charging a transmitter, an interruption of charge can - even for short periods -, let
the charge voltage rise in such a way that the transmitter is destroyed by the overvoltage
immediately. Risk of re!
Notes on batteries handling
• Batteries, and also individual cells are not toys and should be kept out of the
reach of children.
Before each use, check the proper condition of the battery. Do not use defective
or damaged cells / batteries.
• Overcharging and deep discharge lead to irreparable damage to the cells and damage
permanently the capacity of the battery.
• Never store batteries uncharged, discharged or partially charged for long periods. Before storing batteries charge them and from time to time check charge status. NiMH cells
should be 1 V per cell and Lilo / LiPo cells should never be less than 3 V per cell, in order
to achieve an optimum service life.
• Overcharging also damages the capacity of the battery. Therefore do not charge any hot
or charged batteries again.
• High power charge and discharge shorten the life expectancy of the battery. Therefore,
do not exceed the rates stated by the manufacturer.
• Lead-acid batteries are not high power rechargeable. Never exceed the maximum charge
rate stated by the battery manufacturer.
• When buying batteries ensure good quality, rst charge new packs at low rates, and work
up gradually towards higher currents.
• Charge the battery just before you want to use them, the batteries are at their most power.
• Rechargeable batteries / cells must not be heated, burnt, short-circuited or overloaded
with excessive or reversed polarity currents.
• Batteries cells connected in parallel with combination of old and new cells, different features as capacity and voltage, made by different manufacturers, brands or types should
not be used.
• A built-in battery in a device should be removed whenever the device is not used. Always
turn off equipment after use to avoid deep discharge. Recharge the batteries just for the
right time.
• The battery to charge should be placed when charging on a non-ammable, heat re-
sistant and non-conductive pad! Also ammable or highly ammable materials must be
placed away from the charging station.
• Batteries must be charged only under supervision. Observe the maximum specied
charge rate for the specic cell type. Charge current must never be exceeded.
• Should the battery heat during charge to more than 60 ° C, the charge must be stopped
immediately and the battery must be cooled to about 30 ° C.
• Never charge batteries that are hot or not discharged to the rated discharge voltage.
• No changes should be made to the batteries. Never solder or weld directly to the cells.
• Released electrolyte is corrosive, not allow contact with skin or eyes. In an emergency,
rinse immediately with plenty of water and then consult a doctor.
• Suitable extinguishing media are extinguishing blankets, CO2 estinguishers and sand.
• The valve openings of the cells must not be blocked or sealed in any case, for example
by soldering. When soldering do not exceed a temperature of 220° C and for a period not
longer than 20 seconds.
• To avoid deformation, do not produce an excessive mechanical pressure.
• If a battery is overheated, proceed as follows:
Disconnect the battery and place it on a non-combustible surface (stone oor) until it has
cooled. Never keep the battery in your hand to avoid the risks of re and / or explosion.
• Protect batteries from vibration, and do not expose to mechanical stresses.
• When charging and during operation of the batteries, they can generate explosive gas
(hydrogen), be careful with adequate ventilation.
• Never short circuit the batteries. This might cause re and / or explosion!
• Batteries may explode or burn through a defect. We therefore recommend that all lithium,
NiCd and NiMH batteries, should be charged in a LiPo safety case Order Nr. 8370 or 8371.
• Do not open batteries, chemical burn danger.
• NiCd or NiMH battery packs perform their best by rst individually all cells are discharged separately and only then the entire battery pack is charged. Discharging should
be done by the charger cell by cell.
• Make sure that the charge-discharge are done properly.
•
The correct operation cannot be guaranteed in this case. Be sure to check through multiple, monitored test charges, if a proper shutdown occurs for the batteries you are using.
There is a serious re and / or explosion risk!
Charging single NiCd or NiMH cells or batteries with 1 ... 4 cells, can be difcult
for the automatic shut-off. Since the onset after the full load point voltage drop is
not very pronounced, the automatic shut-off cannot or do not respond properly.
Capacity and use time
For all current sources applies: The capacity decreases with every charge. At low temperatures
the internal resistance increases reducing the capacity. As a result, the ability to provide power and
holding the voltage can be reduced.
Frequent charging and / or discharging programs can also lead to a gradual reduction in capacity.
However, current sources should be reviewed at least every 6 months on their capacity, and re-
place them if there is a signicant loss of capacity.
Use only genuine Graupner batteries!
Disposal of waste batteries
Every consumer is legally obliged under the German battery ordinance to return all used
and exhausted dry and rechargeable batteries.
Disposal in the household waste is prohibited. Old batteries can be brought to the public
collection points or given at our retail outlets and wherever batteries of the same type are sold. You
can return used batteries sent by us to the following address:

Damaged batteries need a special packaging for shipping because they are very
toxic!!!!!
Environmental information
DISPOSAL INSTRUCTION
This symbol on the product, user manual or packaging indicates that this product must
not be disposed of with other household waste at the end of its life. It must be handed
over to the applicable collection point for the recycling of electrical and electronic equipment.
The materials are recyclable as marked. By material recycling or other forms of re-usage you are
making an important contribution to environmental protection.
Batteries and accumulators must be removed from the device and disposed of at an appropriate
collection point.
Please inquire if necessary from the local authority for the appropriate disposal site.
General operating information
• When charging the battery it is supplied a certain amount of electricity, which results from multiplying charge current by charge time. The maximum amount of power depends on the capacity
of each battery and the maximum charge current according to the battery type. Both values are
given in the specications of the battery manufacturer.
Only when explicitly rated, fast rechargeable batteries can exceed the normal charging
rate. As STANDARD CHARGE CURRENT, is referred to the 1/10 of nominal capacity: (1/10
C) for a battery with a capacity of 1700 mAh the standard charge current is 170 mA.
• The battery should be connected using a suitable charger cable to the connection terminals of
the charger (red = positive, black = negative). Use only original charging cable with sufcient
cross-section.
• Always follow and observe the recommended charge currents and charge times as rated in the
instructions of the battery manufacturer. Only batteries which are expressly suitable for quick
charge can be charged with the high charging currents provided by this charger.
• Please keep in mind that new batteries reach their full capacity after several charge / discharge
cycles. Some new or deep discharged batteries may also have premature charge termination.
• Should, after a fast charge, a cell of the NiXX battery packs have become particularly hot, this
may indicate a defect of that cell. This battery pack should no longer be used! (Used batteries
have to be disposed of as special waste!).
• Since the charger can only detect the total resistance, but does not distinguish between internal
resistance of the battery, cable resistance and connector transfer resistance, the rst requirement for a proper function is a charging cable with sufcient cross-section and a length of not
more than 30 cm with high performance connectors (gold contacts).
• A transmitter built-in battery can be charged via the tted charge socket.
• Transmitters are often included with a reverse current protection in the form of a diode. This prevents damage for the transmitter from reverse polarity and short circuit between the bare ends
of the charging cable connector. Depending on the design of this diode CAN however even
hinder a correct recognition of the state of charge by the automatic charger.
• The maximum allowable charge current for the transmitter must never be exceeded.
• To prevent internal damage to the transmitter due to overheating due to a fast charge, the transmitter battery should be removed from the transmitter battery compartment.
• The transmitter MUST be switched „OFF“ (OFF) during the charging process!
• Never turn on the transmitter when it is connected to the battery charger.
• Do not discharge the battery through maintenance programs via the charge socket!
The charge socket is not suitable for this use.
• The charger sets the required charging current only as long as the technical possibilities of the
charger are not exceeded! Should it be provided a charging current that the charger technically
cannot afford, the value will be automatically reduced to the maximum possible value. In this
case, the actual charge current will be shown in the display.
• Make sure to check after a „nish“ message that the displayed charge rate shown by the unit is
the same you expected. So you can recognize reliable and timely incorrect shutdown. The probability of false indications depends on many factors, most likely with deep discharged batteries,
low cell counts and particular cell types.
• Make sure, by several test charges, especially on low cell numbers, of the proper function of the
automatic shut-off. Under certain circumstances, fully charged batteries are not detected by a
weak peak, resulting in re and / or explosion hazard!
• The charger might not detect automatically the connected battery type, LiPo or NiMH, in this
case the battery type and the appropriate charge mode must be selected manually! Consequently, please be sure to check before charging: Is this the appropriate charge program, the
correct charging current is set? Failure to comply may result in re and / or explosion!
• Are all connections securely rm, or is there an intermittent contact? Please keep in mind that
the rapid charging of batteries may be dangerous. A break, even for a short time, for example
due to an intermittent contact, leads inevitably to malfunctions, may trigger a restart of the char-
ge and totally overloaded the pack. This represents a re and / or explosion risk!
