7. Information 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.
Thus, imperatively observe the following information and safety measures when handling batteries and
rechargeable batteries.
• Batteries must be kept 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. In such a case, seek instant medical attention!
• Batteries/rechargeable batteries must never be short-circuited, taken apart or thrown into fire. There is a risk of
explosion!
• Leaking or damaged batteries/rechargeable batteries may cause acid burns when coming into contact with skin,
therefore use suitable protective gloves.
• Do not recharge normal batteries. There is a risk of fire and explosion! Only charge rechargeable batteries, which
are intended for this purpose; use suitable rechargeable battery chargers. Batteries (1.5V) are meant to be used
once only and must be disposed of when empty.
• When inserting batteries/rechargeable batteries or when connecting a battery pack or a charger, observe the correct
polarity (note plus/+ and minus/-). Wrong polarity may damage the transmitter, the airplane and the rechargeable
batteries. There is also a risk of fire and explosion!
• Always exchange the entire set of batteries or rechargeable batteries. Do not 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! Use either batteries or rechargeable batteries for the remote control
transmitter.
• If the device is not used for a longer 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.
Caution!
After the flight, the rechargeable flight battery must be disconnected from the helicopter. Do not leave
the rechargeable flight battery connected to the helicopter if the latter is not used (e.g. during transport
or storage). The rechargeable flight battery may otherwise be discharged completely and thus useless!
• Recharge the NiCd or NiMH batteries about every 3 months, as otherwise there may be a total discharge due to
self-discharge, which makes the rechargeable batteries useless.
• Never charge the enclosed rechargeable flight battery immediately after use. Always leave the rechargeable flight
battery to cool down until it has reached room or ambient temperature again. Charge intact and undamaged batteries
only.
