6. Notes on Batteries and
Rechargeable Batteries
• Keep batteries/rechargeable batteries out of the reach of children.
• Do not leave the 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, dismantled or thrown into fire. There is danger of
explosion!
• Leaky or damaged batteries/rechargeable batteries may cause caustic burns if they come into contact with skin.
Therefore, you should use suitable protective gloves.
• Do not recharge normal (non-rechargeable) batteries. There is a risk of fire and explosion! Only charge rechargeable
batteries intended for this purpose. Use suitable battery chargers.
• Observe the correct polarity when inserting batteries or connecting a battery pack (pay attention to plus/+ and
minus/-).
• If the device is not used over a long period of time (e.g. during storage), remove the inserted batteries (or rechargeable
batteries) from the remote control to prevent damage from leaking batteries/rechargeable batteries. Disconnect the
battery pack from the speed controller.
Recharge rechargeable batteries about every 3 months, as otherwise they might be fully discharged due to self-
discharge, which renders the rechargeable batteries useless.
• Always replace the entire set of batteries or rechargeable batteries. Do not mix full batteries/rechargeable batteries
with half-full ones. Always use batteries or rechargeable batteries of the same type and manufacturer.
• Never mix batteries and rechargeable batteries! Either use batteries or rechargeable batteries for the remote control.
The operation of the remote control with rechargeable batteries instead of normal batteries is possible.
However, due to the low voltage (batteries=1.5 V, rechargeable batteries=1.2 V) and the lower capacity
of rechargeable batteries operating time is decreased. Usually this does not matter as the operating
time of the remote control by far exceeds the operating time of the battery pack in the vehicle.
If you use normal batteries in the remote control, we recommend the use of high-quality alkaline batteries.
