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/LiIon rechargeable batteries in particular, various regulations must be
observed under all circumstances due to their high energy content (in comparison to conventional NiCd or NiMH rechargeable
batteries), because otherwise there is a risk 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 them 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 (1.5 V) are meant to be used only once 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 will damage more than just the transmitter, flight model and the
rechargeable batteries. There is also 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 manufacturer.
• Never mix batteries and rechargeable batteries! Use either 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 in use (e.g. during transport or storage). Otherwise, the
flight battery may be fully discharged and thus be 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 flight battery immediately after use. Always leave the flight battery to cool off first (at least 5-10
minutes).
Only charge intact and undamaged rechargeable 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 from
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 to all other chargers and rechargeable
batteries.
• Never leave rechargeable batteries unattended while charging them.
• Disconnect the flight battery from the charger when the rechargeable battery is fully charged.
• Chargers and rechargeable batteries must not get damp or wet. There is a danger to life from electric shock; there also
is a danger of fire and explosion from the reachageable battery!
