Charging
During charge process, a specific quantity of electrical energy is
fed into the battery. The charge quantity is calculated 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 by the battery manufacturer.
Only batteries that are expressly stated to be capable of quick-
charge are allowed to 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. Due to the difference between resistance of
cable and connector, the charger can not detect resistance of the
battery pack, the essential requirement for the charger to work
properly is that the charge lead should be of adequate conductor
cross-section, and high quality connectors which are normally gold-
plated should be fitted to both ends.
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 manufacturer’s
instruction.
Close attention should be paid to the connection of lithium
batteries.
Do not attempt to disassemble the battery pack arbitrarily.
Please get highlighted that lithium battery packs can be wired in
parallel and in series. In the parallel connection, the battery's
capacity is calculated by multiplying single the battery's capacity by
the number of cells, bearing in mind that total voltage stays the
same. If the voltage is imbalanced, it may cause a fire or explosion.
Lithium batteries are recommended to charge in series.
WARNING AND SAFETY NOTES WARNING AND SAFETY NOTES
Discharging
The main purpose of discharging is to clean the residual capacity
of the battery, or to reduce the battery' voltage to a defined level.
The same attention should be paid to the discharging process as
the charging process. The final discharge voltage should be set up
correctly to avoid deep discharging. Lithium batteries cannot be
discharged to lower than the minimum voltage, or it will cause a
rapid loss of capacity or a total failure. Generally, lithium batteries
don't need to be discharged. Please pay attention to the minimum
voltage of lithium batteries to protect them.
Some rechargeable batteries have a memory effect. If they are
partly used and recharged before the whole charge is
accomplished, they remember this and will only use that part of
their capacity next time. This is a 'memory effect' It is said that
NiMH and NiCd batteries are suffering from memory effect. NiCd
has more ‘memory effect’ than NiMH.
Lithium batteries are recommended to be discharged partially
rather than fully. Frequent full discharging should be avoided if
possible. Instead, charge the battery more often or use a battery of
larger capacity. Full capacity cannot be reached until it has been
subjected to 10 or more charge cycles. The cyclic process of
charge and discharge will optimize the capacity of battery pack.

LITHIUM BATTERY(LiPo/LiFe/LiIon)PROGRAM
These programs are only suitable for charging and discharging Lithium
batteries with a nominal voltage of 3.3V, 3.6V and 3.7V per cell. These
batteries need to adopt different charge technique is termed a constant
voltage(CV) and constant current(CC) method. The charge current varies
according to the battery capacity and performance. The final voltage of
charge process is also very important; it should be precisely matched with
the charade voltage of the battery. They are 4.2V for LiPo, 4.1V for Lilo, and
3.6 V for LiFe. The charge current and nominal voltage as for cell count set

PB( LEAD-SULPHUR IC ACID) BATTERY PROGRAM
This is programmed for charging Pb(lead-sulphuric acid) battery with
nominal voltage from 2 to 20V. Pb batteries are totally different from NiCd or
NiMH batteries. They can only deliver relatievely lower current compare to
their capacity, and similar restrictions definitely apply to charge. So the
optimal charge current will be 1/10 of the capacity. Pb batteries must not be
charged rapidly. Always follow the instruction is supplied by the
manufacturer of battery.
When you are willing to alter the parameter value in the program, press
Start/Enter key to make it blink then change the value with or key.
The value will be stored by pressing Start/Enter key once.

User set up starting screen.
The battery is on the cyclic process of charge and
discharge can often become warm after charge or
discharge period. The program can insert a time
delay to occur after each charge and discharge
process to allow the battery adequate time to cool
down before being subjected to the next process.
The value ranges from 1 to 60 minutes.
When you start a charge process, the integral
safety timer automatically starts running at the
same time. This is programmed to prevent
overcharge the battery if it proves to be faulty, or
if the termination circuit cannot detect the battery
full. The value for the safety timer should be
generous enough to allow a full charge of the
battery.
Safe timer Calculation
When charging NiCd or NiMH batteries, divide
the capacity by current, then divide the result by
The user can check battery's total voltage, the highest voltage, the
lowest voltage and each cell's voltage.
Please connect the battery to the charger main battery lead to battery
