•
Connect the battery to be charged to the charger output sockets using a suitable charge lead (red =
positive terminal, black = negative terminal).
•
Be sure to read the information provided by the battery manufacturer regarding charging methods,
and observe the recommended charge currents and charge times. Do not attempt to fast-charge
batteries unless they are expressly stated to be suitable for the high currents which this charger
delivers.
•
Please bear in mind that new batteries do not reach their full capacity until they have undergone
several charge / discharge cycles. You should also be aware that the charger may terminate the
charge process prematurely when connected to new packs, and batteries which have been deep-
discharged.
•
A Ni-Cd pack will normally be warm at the end of a rapid-charge process, but if you notice that one
cell of the pack is much hotter than the others, this may well indicate a fault in that cell. Such packs
could fail completely without warning, and should not be used again. Dispose of the battery safely,
preferably taking it to a toxic waste disposal centre.
•
Ensure that all connectors and terminal clamps make good, sound contact. For example, if there is a
brief interruption due to an intermittent contact, the result is inevitably a malfunction such as a restart
of the charge process, which would result in the pack being massively overcharged.
•
A common cause of malfunctions is the use of unsuitable charge leads. Since the charger is
incapable of detecting the difference between a pack’s internal resistance, cable resistance and
connector transfer resistance, the first requirement if the charger is to work perfectly is that the
charge lead should be of
adequate
conductor cross-section and should be
not be more than
30 cm long
Good-quality connectors (gold-contact types) must be fitted to both ends.
• Charging transmitter batteries
A battery installed in a radio control transmitter can usually be recharged via the integral charge
socket which is fitted to the transmitter itself. Transmitter charge sockets generally include a diode
which prevents reverse current flow. This prevents damage to the transmitter electronics should the
charger be connected with reverse polarity, or if a short-circuit occurs between the bare ends of the
charge lead connectors. However, a transmitter battery protected in this way can only be charged by
the CHARGER if the diode is by-passed. Please read your transmitter operating instructions for
information on how to do this. The stated maximum charge current for the transmitter battery must
never
be exceeded. To avoid possible damage to the internal transmitter components due to
overheating and heat build-up, we recommend that the battery should be removed from the
transmitter’s battery compartment prior to charging. The transmitter must be set to „
OFF
“ and left in
that state for the
whole
period of the charge process.
Never
switch a radio control transmitter on when it is still connected to the battery charger. The
slightest interruption in the charge process may allow the charge voltage to rise to the point where it
immediately
ruins the transmitter.
Never
attempt to carry out any battery discharge or battery maintenance programs via the
