GHARGER PRO-8

09
To avoid short circuit between the charge lead always connect the charge cable to the charger first,
then connect the battery.Reverse the sequence when disconnecting.
Do not connect more than one battery pack to this charger at any one time.
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.
GHARGER PRO-8

Discharging
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'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-dischargeing.
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 used until it has been subjected to
10 or more charge cycles.The cyclic process or charge and discharge will optimize the
capacity of battery pack.

Program flow chart
As default this charger will be set to typical user
settings when it is connected to a 12V battery 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.
GHARGER PRO-8

The screen shows the nominal voltage of Lithium battery.There are three
kinds of Lithium battery:LiFe(3.3V),LiIo(3.6V)or LiPo(3.7V).This information
is of critical importance that you have to check the battery carefully to make
sure it is set up correctly.If it is different from correct value,explosion can
occur during charge process.
The screen shows the сut-off temperature of Lithium battery.you can press
“DEC”or“INC”to select the сut-off temperature(Temp.Rang:20~80℃).The
maximum temperature of the battery can be set during the charge process.
The process will be terminated automatically to protect battery once the
temperature of battery reaches this value.This feature is accomplished
through temperature probe(optional).
GHARGER PRO-8
To avoid from erroneous setting by users,Charger Pro-8 detects the cell count of
Lithium battery automatically at the beginning of charge or discharge process.
But battery that is deep-discharged can't be detected correctly.To avoid this
error,the time term can be set to verify the cell count by the processor.
Normaly,15 seconds are enough to detect the cell count correctly.You need
to extend the time term limit for the battery of large capacity.But the charge or
discharge process may come to an end within the time term because of the
time limit decided by the wrong count if you set too long time limit for the
battery of small capacity.This may cause fatal error.You have to extend the
time term if the processor detect the cell count incorrectly at the beginning of
charge or discharge process.Otherwise,default value is recommended to use.

The program provides maximum capacity protection function.If the Delta-
peak voltage can not be detected or the safety timer times out,the charge
process will stop automatically,when the battery reaches the user-set
maximum charge capacity.
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

Safe timer Calculation
Lithium (LiIo/LiPo/LiFe) program
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=1000)/11.9=92 minutes
1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes
The program is only suitable for charging/discharging Lithium-polymer 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 3.6V,LiIo is 4.1V,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 DEС or INC to change the value.Then press “Start/Enter” key again to store the value.
In this program,here provide you two languages(English and Deutsch).
