•
The battery charger and the drive battery become hot during the charging process. Never cover the
battery charger or drive battery. Do not expose the battery charger or drive battery to extremely high/low
temperatures, direct sunlight or moisture/wet.
•
Never leave batteries unattended when they are charging.
•
Rechargeable batteries should be charged regularly (approx. once every 2 - 3 months) to prevent them
from undergoing deep discharge. This may result in permanent damage and render the batteries use-
less.
NiMH batteries (except special batteries with a low self-discharge) lose their charge within a few weeks.
Lithium batteries usually retain their charge for several months. However, if the batteries undergo deep
discharge, this will result in permanent damage and render them useless.
•
Lithium batteries should not be stored for extended periods of time fully charged, but with only around
50 - 70 % of the available capacity (note the additional information supplied by the battery manufacturer,
if available).
• Never use an excessive charging current; observe the manufacturer's specifications for the ideal/maxi
-
mum charging current. The supplied battery charger is optimally harmonised with the lithium drive bat-
tery.
•
Disconnect the drive battery from the battery charger when it has fully charged.
b) Transmitter
•
When using rechargeable batteries in the transmitter, the operating time will be reduced considerably
due to the lower voltage (rated voltage: disposable battery = 1.5 V, rechargeable battery = 1.2 V).
If you still wish to use rechargeable batteries, we recommend using NiMH batteries with lower self-
discharge. For safety reasons, however, you should use disposable batteries and not rechargeable
batteries.
•
Never mix disposable batteries with rechargeable batteries.
•
Always replace the entire set of batteries in the transmitter.
•
If you do not plan to use the transmitter for an extended period of time, remove the batteries from the
transmitter to prevent them from leaking and causing damage.
c) Vehicle
•
For the vehicle, use only the supplied lithium-ion drive batteries of type "18650" (rated voltage 3.7 V)
or identical replacement drive batteries. Never use other rechargeable or disposable batteries in the
vehicle.
•
If the device is not used for an extended period of time (e.g. in the event of storage), remove the drive
batteries from the vehicle to prevent them from leaking and causing damage.
•
Always use two identical lithium-ion batteries for the vehicle (same manufacturer, same type, same
capacity).
•
Only charge the supplied drive batteries with the supplied battery charger. Never use a different battery
charger as this can result in a fire or explosion of the drive batteries.
