Charging batteries
When a battery is charged, a specific amount of electrical energy is supplied to the battery.
This amount is calculated by multiplying the charging current by the charging time. The
maximum permissible charging current depends on the battery type and can be found in the
information provided by the battery manufacturer.
The standard charging current may only be exceeded if the battery information explicitly
states that the battery is suitable for quick-charge processes. The STANDARD CHARGING
CURRENT is 1/10 of the cells' nominal capacity (e.g. for a 1.7 Ah battery, the standard charging
current is 170 mA).
Notice!
The battery to be charged is connected to the charger's connection sockets (red = positive
pole, black = negative pole). Only use original charging cables with a sufficient wire cross-
section.
Notice!
Always follow the charging instructions of the battery manufacturers and adhere to the charging
current and charging times. The quick-charge process may only be used by batteries that have
explicitly been described as suitable for the high charging current applied by the charger.
Notice!
Please be aware that new batteries only reach their full capacity after several charging/
discharging cycles. Charging may also be terminated prematurely, particularly when new or
deep-discharged batteries are used.
Notice!
If a cell in a LiXX battery pack has become particularly hot following a quick-charge process,
this may indicate a fault in that cell. You must not continue to use this battery pack (exhausted
batteries must not be disposed of as domestic waste).
Notice!
A common cause of malfunctions is the use of unsuitable charging cables. As the charger
cannot distinguish between the battery's internal resistance, cable resistance and connector
resistance, the first requirement for ensuring that the charger functions correctly is to use a
charging cable with a sufficient wire cross-section, that is no more than 30 cm in length and
has high-quality connectors on both sides (gold contacts).
Notice!
A battery installed in a remote-control transmitter can be charged via the charging socket,
which is generally fitted on the transmitter.
Notice!
Transmitter charging sockets usually contain a diode that prevent reverse current. This
prevents damage to the transmitter due to reverse polarity or if a short circuit occurs between
the bare ends of the charging cable connectors.
Notice!
The maximum charging current permitted for the transmitter must never be exceeded.
Notice!
To prevent damage to the internal transmitter components due to overheating and heat build-
up, the transmitter battery should be taken out of the transmitter battery compartment.
