8. Charging the Batteries
Observe chapter 6.
a) Vehicle
• The vehicle may be operated with 4 NiMH batteries type AAA/micro instead of 4 batteries.
The model is delivered without any rechargeable batteries. They must be purchased separately. We recommend
using NiMH batteries with the highest possible capacity (800 mAh or more) to ensure a long driving time. NiMH
rechargeable batteries with low self-discharge are a good choice as well.
• The rechargeable batteries are usually delivered uncharged and must be charged. Before rechargeable battery
reach their maximum capacity, several complete discharge and charge cycles are necessary.
• Use a high-quality charger for single cells for charging. It usually has a quick-charging feature for rechargeable
batteries.
• Rechargeable batteries heat up when charged or discharged (driving the vehicle). Wait until the rechargeable bat-
teries have reached room temperature before charging them. The same applies after the charging procedure. Do
not use the rechargeable batteries in the vehicle until they have cooled down sufficiently after the charging process.
b) Transmitter
Before connecting the charger to the charging socket of the transmitter, always make sure that there are
actually rechargeable batteries inserted. When charging normal (non-rechargeable) batteries, there is a
risk of fire and explosion!
• Only use a charger designed for the respective number of cells in the transmitter and the corresponding recharge-
able battery type. Observe the polarity indication next to the charging socket!
• Rechargeable batteries in the transmitter must not be quick-charged as this damages the transmitter and heats up
the cells in the transmitter excessively. The charging current must not exceed 250 mA (see print on the transmitter
next to the charging socket).
• We recommend not charging rechargeable batteries directly in the transmitter but outside of it; use a high-quality
charger for individual cells.
