7. Information on Batteries and Rechargeable Batteries
Although use of batteries and rechargeable batteries in everyday life is a matter of course today,
there are many dangers and problems. In particular in LiPo/LiIon batteries with high energy content
(as compared to conventional NiMH batteries), various provisions must be complied with to avoid
danger of explosion and fire.
Therefore, always observe the following information and safety notes in handling of batteries and
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; there-
fore, use suitable protective gloves.
• Liquids leaking from batteries/rechargeable batteries are chemically highly aggressive. Objects or sur-
faces that come into contact with them may take severe damage. Therefore, keep batteries/rechargea-
ble batteries in a suitable location.
• Do not recharge normal, non-rechargeable batteries. There is a risk of fire and explosion! Charge only
rechargeable batteries intended for this; use suitable chargers.
Batteries (1.5 V) are intended for one-time use only and must be disposed of properly when discharged.
• Always observe the correct polarity when inserting batteries into the transmitter or connecting the flight
battery (observe plus/+ and minus/-).
Incorrect polarity will damage not only the transmitter but also the plane model and the rechargeable
battery. There is a danger of fire and explosion.
• Always replace the whole set of batteries in the transmitter. Do not mix full batteries with half-full ones.
Always use batteries/rechargeable batteries of the same type and manufacturer
• Only use high-quality alkaline batteries for the remote control transmitter. When using rechargeable
batteries, the charging electronics in the transmitter will be unable to charge the flight battery sufficiently.
• If the device is not used for an extended period of time (e.g. storage), remove the inserted batteries from
the remote control transmitter to avoid damage from leaking batteries.
• D o not leave the rechargeable flight battery connected to the plane model 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!
Remove the flight battery from the model plane for recharging.
• Never charge the flight battery right after use. Always leave the LiPo flight battery to cool off first (at least
5 - 10 minutes).
• Only charge intact and undamaged batteries. If the outer isolation of the rechargeable battery is dama-
ged or the battery is deformed or bloated, it must not be charged. In this case, there is immediate danger
of fire and explosion!
