A battery pack which consists of different types of cells (including different
manufacturers)
A battery that is already fully charged or just slightly discharged.
Non-rechargeable batteries (Explosion hazard).
Batteries that require a different charge technique from NiCd, NiMh, LiPo or Gel cell
(Pb, Lead acid).
A faulty or damaged battery.
A 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.
Please bear in mind the following points before commencing charging:
Did you select the appropriate program suitable for the type of battery you are
charging?
Did you set up adequate current for charging or discharging?
Have you checked the battery voltage? Lithium battery packs can be wired in parallel
and in series, i.e. a 2 cell pack can be 3.7V (in parallel) or 7.4V (in series).
Have you checked that all connections are firm and secure?
Make sure there are no intermittent contacts at any point in the circuit.
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, recommended charging current and charging time. Especially, the
Lithium battery should be charged according the charging instruction provided
by the manufacturer strictly.
Never attempt to charge or discharge the following types of batteries.
WARNING AND SAFETY NOTES

Discharging
The main purpose of discharging is to clean 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 charging. The final discharge voltage should be set up
correctly to avoid deep-discharging. Lithium battery can not be discharged to lower
than the minimum voltage, or it will cause a rapid loss of capacity or a total failure.
Generally, Lithium battery doesn't need to be discharged. Please pay attention to the
minimum voltage of Lithium battery to protect the battery.
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 NiCd
and NiMH batteries are suffering from memory effect. NiCd has more memory effect
than NiMH.
Lithium batteries are recommended to be discharged partially rather than fully
discharged. 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.
Attention should be paid to the connection of Lithium battery especially.
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 battery capacity by the number of cells with total voltage stay the same. The
voltages imbalance may cause fire or explosion .Lithium battery is recommended to
charge in series.

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 on the charge program must
always be correct for the battery to be charged.
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 INC or DEC key. The value will be stored by
pressing Start/Enter key once.
Charging Lithium battery at balance mode
This function is for balancing the voltage of Lithium-polymer battery cells while charging.
In the balance mode, the battery needs to have a balance lead to connect to the battery's
power lead to the output of charger.
In this mode, the charging process will be different from ordinary charging mode. The
internal processor of the charger will monitor the voltages of each cell of the battery pack
and controls charging current that is feeding to each cell to normalise the voltage.
Note: We recommends charging lithium batteries with a balance lead in the balance
mode only.
