Thank you for choosing the Intelligent Digital Battery Charger/Discharger DCN50-II.
You get a rapid charger/discharger that is computerized with a high performance
microprocessor and specialized operating software. It can maintain your battery at its best
condition and also control them safely.
Please read this entire operating manual completely and attentively as it contains a
wide variety of specific programming and safety information.
zSpecial features
-High-power and high-performance circuit
DCN50-II employs the circuit that has maximum output power of 50W .As a result it
can charge or discharge up to 12 cells of NiCd/NiMH, 4 series of Li-ion/poly and 6/12V
Lead-acid batteries with maximum current of 2.5A.
- Optimized operating software
When charging or discharging,DCN50-1 has an ‘AUTO’ function that set the charging
voltage automatically for NiMH/NiCd batteries，it can prevent from over-charging can lead
to an explosion by users fault. Every program in the unit is controlled with mutual links and
communicates for every possible error so it introduces a maximum safety. These can be
set at users option.
- Maximum safety
Delta-peak sensitivity: The automatic charge termination program works on the
principle of the Delta-peak voltage detection. The charge monitors the voltage curve and
assessment of the peak with the charging time increment. This indicates the terminal point
of charging accurately.
Input power monitor: To protect the car battery using as input power from being
damaged the voltage of it always monitored. If it drops below the lower limit the process
will be ended automatically.
Fault condition protection: This device will not start operating when “battery polarity
reverse”, “battery wire opened” and “battery or terminals shorted”.

●Warnings and safety notes
Be sure to understand the information of the battery to be charged or
discharged accurately. If the program is set up incorrectly the battery can
severely be damaged. Especially Lithium battery can cause a fire or an
explosion by over-charging.
Never leave the charge unsupervised when it is connected to its power supply. If any
malfunction is observed immediately terminate the process and refer to the operation
manual.
Keep away the unit from dust, damp, rain, heat direct sunshine and vibration. DO not
drop it.
The circuit of the unit is designed to be powered by a 12V DC only.
This unit and the battery to charge or discharge should be set up on a head-resistant,
non-inflammable and non-conductive surface. Never place them on a car seat, carpet
or similar. Keep all the inflammable volatile materials well away from operating area.
The outer case slots and fan serve to cool the charger so must not be covered of
enclosed. Provide good ventilation.
To avoid short-circuits between the charge lead, always connect the battery cable to
the unit first and only then to the battery to be charged or discharged. Reverse the
sequence when disconnecting.
-The battery exceeds the limit ofDCN50-II’s specification.
-Battery pack, which consists of different types of cell (including different
manufacturers).
-Battery, which is already fully charged or just slightly discharged.
-Non-rechargeable batteries (Explosion hazard).
-Batteries that require a different charge technique from NiCd, Nimh, Li-Ion,
Li-Poly or Pb.
-Faulty or damaged battery.
-Battery fitted with an integral charge circuit or a protection circuit.
-Batteries installed in a device, or which are electrically linked to other
components.
-Batteries that are not expressly stated by the manufacturer to be suitable for the
currents the charger delivers during the charge process.

zGeneral notes
How to select charge current level?
This device provide four charge current levels(0.5A, 1.0A, 2.0A, 2.5A) for user
select. The charge current level depend on the capacity of the battery-pack and the
charge time you wanted. The maximum permissible charge current varies
according to the battery type or its performance, and can be found in the information
provided by the battery manufacturer. Generally, we suggest NIMH and NICD
battery-pack use 0.2~0.3C(the nominal capacity of Battery-pack), Li-Ion/Poly
battery-pack use 0.2~0.5C, Lead-Acid(Pb) battery use 0.1~0.2C. It is only allowed
to charge batteries at rates higher than the standard charge current if they are
expressly stated to be quick-charge capable. The charge current level is higher, the
time you expend is shorter.
When you need discharge?
-Some rechargeable batteries are said to have a memory effect. If they are partly
used and recharged before the whole charge is drawn out, they ‘remember’ this
and next time will only use that part of their capacity. This is a ‘memory effect’.
NiCd and NiMH batteries are said to suffer from memory effect. They prefer
complete cycles; so you should discharge the battery-pack empty before charge.
This device provide a fixed 0.5A discharge function for user select.
-The Lithium battery and Pb battery prefers a partial rather than a full discharge.
Frequent full discharges should be avoided if possible.
-If you want check the battery-pack’s capacity, you can select discharge function
after you full charged this battery-pack.
