8. Charging Rechargeable Batteries
If you use rechargeable batteries for power supply of the receiver, they are usually flat at delivery and must be
charged.
Observe:
Before a rechargeable battery reaches maximum capacity, several complete discharge and charge cycles
are necessary.
Always discharge the rechargeable battery at regular intervals, since charging a "half-full" rechargeable
battery several times can cause a so-called lazy battery effect. This means that the rechargeable battery
loses capacity. It no longer provides all of its stored energy, and the operating time of the model is reduced.
If you use several rechargeable batteries, purchasing a high-quality charger may be worthwhile. Such a
charger usually has a quick-charging feature.
