6. 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 particular, various regulations must be
observed under any circumstances due to their high energy content (in comparison to conventional NiCd or NiMH recharge-
able batteries), because otherwise there is danger of explosion and fire.
Make sure to observe the following information and safety information when handling batteries or rechargeable batteries.
• Keep batteries/rechargeable batteries out of the reach of children.
• Do not leave any batteries/rechargeable batteries lying 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 can cause chemical burns to skin at contact; therefore, 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. Batteries (1.5V) are meant to be used once only and must be properly
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 not only damage the transmitter, flight model and the recharge-
able batteries. There is a risk of fire and explosion.
• Always replace the entire set of batteries or rechargeable batteries. Never mix fully charged batteries/rechargeable
batteries with partially discharged ones. Always use batteries or rechargeable batteries of the same type and manufac-
turer.
• Never mix batteries and rechargeable batteries! Either use batteries or rechargeable batteries.
• 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.
Attention!
After the flight, the 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). Otherwise, the flight
battery may be fully discharged and is thus destroyed/unusable!
• Recharge the rechargeable batteries about every 3 months. Otherwise, so-called deep discharge may result, rendering
the rechargeable batteries useless.
• Never charge the enclosed flight battery immediately after use. Always leave the flight rechargeable battery to cool off
first (at least 5-10 minutes).
Only charge intact and undamaged batteries. If the external insulation of the rechargeable battery is damaged or if the
rechargeable battery is deformed or bloated, it must not be charged. In this case, there is immediate danger of fire and
explosion!
• Never damage the flight battery covering, do not cut the foil cover, do not probe the rechargeable battery with sharp
objects. There is a risk of fire and explosion!
• Remove the flight battery that is to be charged from the model and place it on a fire-proof support. Keep a distance to
flammable objects.
• Always charge rechargeable batteries at the current indicated by the manufacturer and observe that the permissible
maximum values are not exceeded.
• As the charger as well as the flight battery heat up during the charging process, it is necessary to ensure sufficient
ventilation. Never cover the charger or the flight battery! Of course, this also applies for all other chargers and recharge-
able batteries.
• Never leave batteries unattended while charging them.
• Disconnect the flight battery from the charger when the rechargeable battery is fully charged.
• Charges and rechargeable batteries must not get damp or wet. The charger and the flight battery must not become damp
or wet!
