If you do not plan to use the charger for an extended period, disconnect any connected batteries from
the charger, and then disconnect the charger from the power supply.
•
Do not charge a battery when it is still hot (e.g. due to a high discharge current in your model). Allow the
battery to cool down to room temperature before charging or discharging it.
• Never damage the casing of a rechargeable battery. This may cause a fire or explosion!
• Never charge or discharge damaged, leaking or deformed batteries. This may cause a fire or explosion!
Discontinue use immediately and dispose of the battery in an environmentally friendly manner.
•
Disconnect the battery from the charger when the battery is fully charged.
•
Rechargeable batteries should be charged at least once every 3 months to prevent damage due to
overdischarge.
•
Store rechargeable batteries in a suitable location. Install a smoke detector in the room. Batteries pre-
sent a fire hazard and may generate toxic fumes. This applies in particular to batteries for model toys,
which are subjected to high charging/discharge currents and vibrations.
b) Additional information about lithium rechargeable batteries
Modern lithium rechargeable batteries have a significantly higher capacity than NiMH and NiCd batteries
and are more lightweight. This makes lithium batteries (especially lithium polymer batteries) particularly
suitable for use in model making.
However, lithium batteries require particular care to ensure safe charging/discharging, operation and han-
dling.
The following section provides an overview of the potential hazards associated with lithium batteries and
explains how these hazards can be avoided to ensure a long lifespan.
Please also refer to the battery safety information in section 6a.
• The casing of many lithium batteries is made of a thick film, which is very sensitive.
Do not dismantle, drop or insert any objects into lithium batteries. Do not apply mechanical loads or pull
on the battery’s connection cables. This may cause a fire or explosion!
Always observe these instructions when inserting or removing a battery from your model.
•
Ensure that the battery does not overheat during use, recharging, discharging, transport or storage. Do
not place rechargeable batteries next to sources of heat (e.g. a speed controller or motor) or expose
them to direct sunlight. This may cause the battery to overheat, which can cause a fire or explosion!
The temperature of the battery must not exceed 60 °C (or the maximum temperature stated in the
manufacturer’s instructions).
•
If there are any signs of damage (e.g. if your model is subjected to an impact), or the battery casing is
swollen, discontinue use immediately. Do not attempt to recharge the battery, as this may cause a fire or
explosion!
Exercise caution when handling the damaged battery and use suitable protective gloves. Dispose of the
battery in an environmentally friendly manner.
Never store damaged batteries in an apartment or in a house/garage. Damaged or swollen lithium bat-
teries may catch fire.
