7. Charging the Batteries
a) Charging the Drive Battery for the Vehicle
• No rechargeable drive battery is included in the delivery. It must be ordered separately. This enables you to choose
whether you want to use a low-cost beginner’s battery or a high-quality professional battery with a high capacity.
• The drive battery is delivered uncharged and must be charged. Several complete discharge and charge cycles are
necessary before the drive battery delivers its maximum power.
• If you still use NiCd drive batteries, they should be run empty at all times, because repeated charging of a „half-full“
NiCd drive batters can cause a memory effect. That means that the drive battery loses its capacity; it no longer
releases all of its stored energy and the driving time is decreased.
For rechargeable batteries with NiMH technology, recharging partially discharged rechargeable batteries does not
cause any problems.
• High-quality drive batteries not only have a higher capacity, which allows you to drive your model vehicle much
longer, but also deliver a higher output voltage under load. This gives the motor more power and results in better
acceleration and higher speed.
• We recommend purchasing a high-quality charger. Such a charger usually has a quick-charging feature.
• Rechargeable batteries heat up when charged or discharged (driving the vehicle). Wait until the rechargeable batteries
have reached room temperature before charging them. The same applies after the charging procedure. Do not use
the rechargeable battery in the vehicle until it has cooled down sufficiently after charging.
• Only use a charger suitable for the battery type (NiCd/NiMH) used.
• Remove the drive battery from the vehicle for charging.
b) Charging Rechargeable Batteries in the Transmitter
The included transmitter may not have a charging socket; observe the included operating instructions for
the transmitter. In this case, remove the inserted batteries and charge them externally.
If your transmitter has a charging socket, check whether there are actually rechargeable batteries inserted
in the transmitter before connecting the charger. When charging normal (non-rechargeable) batteries,
there is a risk of fire and explosion!
• We recommend not charging rechargeable batteries directly in the transmitter but with a high-quality charger for
individual cells instead.
• Rechargeable batteries in the transmitter must not be quick-charged as this damages the transmitter and heats up
the cells in the transmitter excessively. Observe the maximum permissible charging current as indicated on the
transmitter or in the operating instructions of the remote control system.
• Only use a charger designed for the respective number of cells in the transmitter and the corresponding rechargeable
battery type.
