WARNING AND SAFETY NOTES
!
!
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.

WARNING AND SAFETY NOTES
!Discharging
10
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.
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's capacity by
the number of cells with total voltage stay the same. The voltage's imbalance may cause fire or
explosion .Lithium battery is recommended to charge in series.
The main purpose of discharging is to clean residual capacity of the battery, or to reduce the
battery’s 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.

As default this charger will be set to typical user settings when it is connected to DC 11~18V for
the first time. The screen displays the following information in sequence and the user can change
the parameter on each screen.
If you need 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.

User setup starting screen.
The screen displays the nominal voltage of Lithium battery. There are three
kinds of Lithium battery: LiFe(3.3V), Lilo(3.6V) or LiPo(3.7V). This is very
important so you have to check the battery carefully and set it up correctly. If it
is different from correct value the battery may be exploded during charge
process.
X-605 recognize the cell count of Lithium battery automatically at the
beginning of charge or discharge process to avoid from erroneous setting by
user. But deeply discharged battery can be perceived incorrectly. To prevent
the error, you can set the time term to verify the cell count by the processor.
Normally, 10 minutes are enough to perceive the cell count correctly. For the
battery of larger capacity, you may extend the time term. But if you set the time
term to long for the battery of smaller capacity, the charge or discharge
process can be finished within the time term with the erroneous cell count. This
may cause the fatal result. If the processor recognizes the cell count
incorrectly at the beginning of charge or discharge process, you may extend
the time. Otherwise, you had better use with the default value.

This shows the trigger voltage for automatic charge termination of NiMH
and NiCd battery. The effective value ranges from 5 to 20mV per cell. If the
trigger voltage is set higher, there is a danger of overcharging the battery; if
it is set lower, there is a possibility of premature termination. Please refer
the technical specification of the battery. (NiCd default: 12mV, NiMH
default: 7mV)
An optional feature using temperature probe contacting the surface of bat
tery, the temperature cut-off can be on or off. If it is on, set the maximum tem
perature at which the charger should allow battery to reach during charge.
Once a battery reaches this temperature during charge, the process will be
terminated to protect the battery.

The battery becomes warm after cycles of charge/discharge process. The
program will insert a time delay after each charge/discharge process to
allow the battery enough time to cool down before beginning next cycle of
charge/discharge process. The valid value ranges from 0 to 60 minutes.
When the charge process starts, the integrated safety timer starts to run
simultaneously. If error detected or the termination circuit can not detect
whether the battery is fully charged or not, this unit is programmed to
prevent overcharging. Please refer to the below statement to calculate
the timer you set.
Safe timer Calculation
When charging NiCd or NiMH batteries, divide the capacity by current, then
divide the result by 11.9, set this number of minutes as the value for safety
timer setting. If the charger stopped at this time threshold, about 140% of the
capacity will have been fed into the battery.
For example:
Capacity Current Safety Time
2000mAh 2.0A (2000/2.0=1000)/11.9=84 minutes
3300mAh 3.0A (3300/3.0=1100)/11.9=92 minutes
1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes

INITIAL PARAMETER SETUP (USERS SET UP)

The program is only suitable for charging/discharging Lithium(LiPo/LiIo/LiFe) batteries with a
nominal voltage of 3.3/3.6/3.7V/cell. Different batteries have different charge technique. There
are two methods termed as constant voltage and constant current. The charge current varies
according to battery capacity and specification. The final voltage is very important; it should
precisely match the voltage of the battery: LiPo is 4.2V, LiIo is 4.1V and LiFe is 3.6V. The current
and voltage of the battery should be correctly set.
When you want to change the values of parameters, please press START/ENTER key to make it
blink and then use DEC or INC to change the value. Then press START/ENTER key again to
store the value.

BALANCE CHARGING OF LITHIUM BATTERY
Balance charging of lithium battery
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 individual balance port
at the right side of the charger. And you need to connect the battery's power lead to the output of
charger.
Charging in this mode is different from the normal modes, because the built-in processor
monitors voltage of individual cell and control input current fed into each cell to equalized
voltage of individual cell.
