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.

z Special 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.
