WARNING AND SAFETY NOTES
oTo 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.
o
oDo not connect more than one battery pack to this charger at anyone time.
Never attempt to charge or discharge the following types of batteries.
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).
I
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.

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 setup adequate currentfor charging or discharging?
Have you checked the battery voltage? Lithium battery packs can be
wired in parallel and in series, i.e. a 2cell pack canbe 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
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.
I
Attention should be paid to the connection of Lithium battery especially.
Do not attemptto disassemble the battery pack arbitrarily
Please get highlighted that lithium battery packs can bewired 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 orexplosion .Lithium battery is recommended to charge in series.
----------------------
•• 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 bedischarged to lowerthan the minimum voltage, or itwill
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 of charge and discharge will optimize the capacity of
battery pack. r. 0

INITIAL PARAMETER SETUP [USERS SET UPI
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 usercan
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.

INITIAL PARAMETER SETUP lOSERS SET UPI
The screen shows the nominal voltage of Lithium battery. There are
three kinds of Lithium battery: LiFe(3.3V), Lilo(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.
To avoid from erroneous setting by users,B6+ 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.
Toavoid this error, the time term can beset to verifythe cell countby the
processor. Normally, 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 ofthe 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.
I
This shows the trigger voltage for automatical charge termination of
NiMH and NiCd battery. The valid value ranges from 5 to 20 mV per cell.
Setting the trigger voltage higher brings a danger of overcharging;
whereas setting it lower brings a possibility of premature termination.
Please refer to the technical specification of the battery.(NiCd
default: 12mV, NiMH default:7mV)

INITIAl PARAMETER SETUP lOSERS SET UP)
There is a 3-pin port on the left of the charger used as USB interface or temperature sensor port.
If the screen displays temperature, you can use the optional temperature probe to connect tothe
surface of the battery, Ifit is set as the USB port, you can connect the chargerto your PC through
the optional USB cable to monitor the charging process through optional software.
The maximum temperature of the battery can be setduring the charge process. The process will
be terminated automatically to protect battery once the temperature of battery reaches this
value. T",hisfeature is accomplished through temperature probe (optional).
~DEG.I;lNC~
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. Thevalid value ranges from 1 t060 minutes.
I
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.
The program provides maximum capacity protection function. If the Oelta-
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,
The beep to confirm users' operation sounds every time a button is pressed.
The beep or melody sounds at various times during operation to confirm
different mode change. These functions can be switched on or off.
This function monitors the voltage of the input battery used to power this
charger. If the voltage is lower than user-set value, the program will end
forcibly to protectthe input battery.

INITIAL PARAMETER SOUP [USERS SETUP]
Safe timer calculation
When charging NiC,d or NiMH batteries, divide the capacity by current, then divide the result by
11.9, setthis number of minutes as the value for safety timer setting. Ifthe charger stopped at
this time threshold, about 140% ofthe 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=11 00)/11.9=92 minutes
1000mAh 1.2A (1000/1.2=833)/11.9=70 minutes
Lithium (LiloILiPoILiFe) program
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, LiLo is 4.1V and liFe is 3.6V. The current and
voltage of the battery should be correctly set.
When you wantto change the values of parameters, please press START/ENTER key tomake it
blink and then use DES or INC to change the value. Then press START/ENTER key again to
store the value.
