7. Charging accumulators
a) Loading the accumulator pack
• Accumulators are not part of the delivery and must be ordered separately. This allows you to chose whether you
want to use a low-cost beginner's accumulator or a high-quality professional accumulator with a high capacity.
• The accumulator pack is empty on delivery and must be charged.
• Before the accumulator pack delivers its maximum power, several complete discharge and charge cycles are
necessary.
• Always drive the accumulator pack empty, as recharging a "half-full" accumulator pack repeatedly, can cause a so
called memory effect. This means that the rechargeable battery pack loses its capacity, it no longer releases all of its
saved energy, drive time is decreased.
This effect is much slighter in accumulators with NiMH technology, and recharging partially discharged accumulators
is less problematic.
• High-quality accumulators not only have a higher capacity, which allows you to drive your model vehicle much longer
and also delivers a higher output voltage for extreme situations. This gives the engine more power and results in
better acceleration and a higher speed.
• If you are using several accumulator packs or accumulators, purchasing a high-quality charger may be worthwhile.
They are normally also suitably for fast charging of accumulators.
• Accumulators heat up during charging/discharging (driving the vehicle). Wait until the accumulator has reached
room temperature before charging it. The same applies after the charging procedure. Do not use the accumulator in
the vehicle until it has cooled down sufficiently after the charge process.
b) Charging accumulators in the transmitter
Prior to connecting a charger to the transmitter's charge socket, check whether accumulators are actually
inserted. When charging normal (non-rechargeable) batteries there is a risk of fire and explosion!
• The charge socket (see chapter 8, position 11) is designed for a round plug with an external diameter of 2.5mm, the
internal contact must carry "Plus/+".
• We recommend not charging accumulators directly in the transmitter but instead with a high-quality charger for
individual cells.
• Accumulators in the transmitter may not be quick-charged, as this damages the transmitter and heats up the cells in
the transmitter. Depending on the applied accumulators, we recommend a maximum charge current of 200-300mA.
Please note the label on the charge socket or the type plate.
• Only use a charger designed for 8 AA/mignon cells and the corresponding accumulator type (NiCd, NiMH).
