1.1. Warnings and Safety Information
Charging
During the charge process, a specifi c quantity of electrical
energy is fed into the battery. The charge quantity is calcu-
lated by multiplying charge current by charge time. The
maximum permissible charge current varies depending on
the battery type or its performance, and can be found in
the information provided by the battery manufacturer. Only
batteries that are expressly stated to be capable of quick
charge should be charged at rates higher than the standard
charge current.
Connect the battery to the terminal of the charger. Red is
positive and black is negative. In the event there is any
signifi cant resistance in the battery cable and/or connector,
the charger will not be able to properly detect the resistan-
ce of the battery pack resulting in an error. It is essential in
order for the charger to operate properly that the battery
charge leads should be of adequate quality for the size of
the battery.
Always refer to the manual by the battery manufacturer
pertaining to charging methods. Operate according to their
recommended charging current and charging time. Lithium
batteries, in particular, should be charged strictly according
to the manufacture's instruction.
Pay close attention to the connection of lithium batteries.
Do not attempt to disassemble the battery pack.
Notice
This charger was designed and approved exclusively for

Professional Balance Charger, Discharger
Please take note that lithium battery packs can be wired
in parallel and in series. In the parallel connection, the
battery's capacity is calculated by multiplying the single
battery's capacity by the number of cells, bearing in mind
that total voltage stays the same. If the voltage is imbalan-
ced, it may cause a fi re or explosion. Lithium batteries are
always recommended to be charge in series.
Discharging
The main purpose of discharging a battery is to clean the
residual capacity of the battery or to reduce the battery's
voltage to a defi ned level. It is critical that the same
attention be paid to the discharging process as to the
charging process. The fi nal discharge voltage should be set
correctly to avoid deep discharging. Lithium batteries
cannot be discharged to voltage lower than the minimum
voltage for the cell type. Doing so will result in a rapid loss
of capacity and/or total failure. Generally, lithium batteries
don't need to be discharged and it is not recommended. If
you choose to discharge your lithium batteries make sure
to pay attention to the minimum voltage setting.
Some rechargeable batteries have a memory effect. If they
are partly used and recharged before the complete charge/
discharge cycle is accomplished, they remember this and
will only use that part of their capacity next time. It is
generally known that NiCd and NiMH batteries suffer from
this memory effect.
Unless otherwise prescribed by law, the limit of our liability
shall not exceed the invoice value of the charger.
