7. Notes on Batteries and Rechargeable Batteries
Despite the fact that handling batteries and rechargeable batteries in daily life nowadays is a matter of fact,
there are still numerous dangers and problems involved. For LiPo/Lion rechargeable batteries in particu-
lar, various regulations must be observed under any circumstances due to their high energy content (in
comparison to conventional NiCd or NiMH rechargeable batteries), because otherwise there is danger of
explosion and fire.
The helicopter is delivered without batteries and charging device. Nevertheless, we are including exten-
sive information on handling batteries for safety reasons. Please observe the manufacturer's information
included with the rechargeable batteries.
a) Transmitter
• Keep batteries/rechargeable batteries out of the reach of children.
• Do not let batteries/rechargeable batteries lie around openly. There is a risk of batteries being swallowed by children
or pets. If swallowed, consult a doctor immediately!
• Batteries/rechargeable batteries must never be short-circuited, disassembled or thrown into fire. There is a danger
of explosion!
• Leaking or damaged batteries/rechargeable batteries may cause acid burns when coming into contact with skin.
Use suitable protective gloves.
• Do not recharge normal batteries. There is a risk of fire and explosion! Only charge rechargeable batteries intended
for this purpose. Use suitable battery chargers.
• When inserting batteries/rechargeable batteries or when connecting a battery pack observe correct polarity (note
plus/+ and minus/-).
• If the device is not used for an extended period of time (e.g. storage), remove the inserted batteries (or rechargeable
batteries) from the remote control to avoid damage from leaking batteries/rechargeable batteries.
• Recharge the NiCd or NiMH rechargeable batteries about every 3 months, as otherwise there may be a total dis-
charge due to self-discharge, which renders the rechargeable batteries useless.
• Always replace the entire set of batteries or rechargeable batteries. Never mix full batteries/rechargeable batteries
with half-full ones. Always use batteries or rechargeable batteries of the same type and manufacturer.
• Never mix batteries and rechargeable batteries!
The remote control (transmitter) may be operated with rechargeable batteries instead of batteries.
However, the lower voltage (batteries=1.5 V, rechargeable batteries=1.2 V) and the lower capacity of re-
chargeable batteries do lead to a decrease of the operating time. However, normally this does not matter,
since the operating time of the transmitter is far beyond that of the helicopter.
If you use batteries in the remote control, we recommend the use of high-quality alkaline batteries.
When rechargeable batteries are used, the range can be reduced.
