7. Notes 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 NiCd or 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!
• To charge the drive battery, remove it from the model and place it on a fire-proof surface. Keep a distance to
flammable objects.
• As the charger as well as the drive battery heat up during the charging process, it is necessary to ensure sufficient
ventilation. Never cover the charger or the drive battery! Of course, this also applies for all other chargers and
rechargeable batteries.
• Never leave batteries unattended while charging them.
• Do not expose the charger or drive battery to high/low temperatures or to direct solar radiation.
• Disconnect the drive battery from the charger when it is fully charged.
• Chargers may only be operated in dry rooms. Charges and drive batteries must not get damp or wet.
• 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.
Liquids leaking from batteries/rechargeable batteries are chemically highly aggressive. Objects or surfaces that
come into contact with them may take severe damage. Therefore, keep batteries/rechargable batteries in a suitable
location.
• Do not recharge normal batteries. There is a risk of fire and explosion! Charge only rechargeable batteries intended
for this; use suitable chargers.
• Observe to correct polarity when inserting batteries into the transmitter or connecting the drive battery to the speed
controller (positive/+ and negative/-).
• If you do not use the model for an extended period of time (e.g. during storage) remove the batteries (or rechargeable
batteries) inserted in the remote control to avoid damage from leaking batteries.
• Recharge the rechargeable batteries about every 3 months. Otherwise, so-called deep discharge may result, rendering
the rechargeable batteries useless.
• Always replace the entire set of batteries or rechargeable batteries in the transmitter. 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!
• When handling LiPo batteries, observe the special safety information of the battery manufacturer!
