SPECIAL FEATURES
SPECIAL FEATURES
Optimized operating softwareThe C6 charger features an automatic charging function that sets
the operating current during the process of charging or discharging. This can prevent
overcharging of lithium batteries which may lead to a battery fire and explosion. It will
disconnect the circuit automatically and alarm the user once a malfunction is detected. All
programs of this charger are controlled through two-way communication, achieving maximum
safety and easy to use. All settings are user configurable.
Internal independent lithium battery balancer
C6 employs an individual-cell voltage balancer. It isn't necessary to connect an external
balancer for balance charging.
Balancing individual cells battery discharging
During the process of discharging, C6 can monitor and balance each cell of the battery
individually. If the charger detects that the voltage of any single cell is abnormal, an error
message will be displayed and the process will be ended automatically.
Adaptable to various type of lithium battery
C6 can charge various types of lithium batteries including Li-ion, LiPo and the new LiFe
batteries.

Fast and storage mode of lithium battery
The 'fast' mode is used to reduce the charge duration, whereas the 'storage' mode can control
the final voltage of the battery. This will allow long-term storage of the battery and protect the
useful life of the battery.

Maximum safety
Delta-peak sensitivity: The automatic charge termination is based on the principle of the delta-
peak voltage detection. When the battery's voltage exceeds the threshold, the process will be
terminated automatically.
SPECIAL FEATURES
Automatic charging current limit
You can set up the upper limit of the charging current when charging NiCd or NiMH batteries.
This is useful for NiMH batteries of low impedance and capacity when using the 'AUTO' charging
Capacity limit
The charging capacity is calculated as the charging current multiplied by time. If the charging
capacity exceeds the limit, the process will be terminated automatically when the maximum
value you have set is reached.
Temperature threshold*
The battery's internal chemical reaction will cause the temperature of the battery to rise.
If the temperature limit is reached, the process will be terminated automatically.*
* This function is available by connecting the optional temperature probe, which is not included.
Processing time limit:
You can also limit the maximum process time to avoid overcharging the battery.
Input power monitoring
To protect the car battery from being damaged when used as DC power input, the voltage is
continuously monitored. If it drops below the lower limit, the process will be ended automatically.
Data store/load
Data for a maximum five batteries can be stored for your convenience. You can store data
pertaining to program settings of the battery for continuous charging or discharging. Users can
recall this data at any time without any special program setting.

currents the charger delivers during the charge process.

WARNING AND SAFETY NOTES
!
!
Please bear in mind the following points before commencing charging:
Charging
While charging, 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. Check with
manufacturer for the battery specifications you are using. 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). Use
conductors with adequate cross-section and high quality connectors, normally gold-plated, to
meet the charging and discharging purpose.
10
Did you select the appropriate program suitable for the type of battery that 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.

WARNING AND SAFETY NOTES
Always refer to the recommendations by battery manufacturer for charging current and time.
This is strictly important for lithium batteries.
Attention should be paid to the connection of Lithium battery especially.
Do not attempt to disassemble batteries.
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.
!Discharging
The main purpose of discharging is to clear capacity of the battery and 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 over-discharging the
battery. Lithium battery cannot be discharged to lower than the minimum voltage without
rapidly reducing capacity and risk to failure. Generally, lithium batteries do not need to be
discharged. Please pay attention to the minimum voltage of lithium battery in order to protect
the battery.
Some rechargeable batteries have a memory effect. If they are partially discharged and then
recharged, those charges will be limited to reduced capacity. This is a memory effect. The
NiCd and NiMH batteries are sensitive to memory effect as NiCd has more expose to this.
Lithium batteries are recommended to be discharged partially. Frequent full discharging
should be avoided. You should charge the battery more often or use a battery of higher
capacity. The charge and discharge cycle will optimize the capacity of battery pack.

The C6 detects the cell count of lithium battery automatically at the
beginning of charge or discharge process. A battery might not be
detected if it has been over-discharged. You can set the time limit to
verify the cell count by the processor. Normally, 15 seconds are enough
to detect the cell count correctly. You have to extend the time term limit
for batteries of large capacity. If the cell count is wrong or you set too
long of a time limit the charge or discharge process may come to an end
within the time limit. This may cause a 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, use the default
value.
This shows the trigger voltage for automatic charge termination of NiMH
and NiCd batteries. The valid value ranges from 5 to 20 mV per cell.
Setting the trigger voltage higher may lead to overcharging, whereas
setting it lower brings a premature termination. Please refer to the
technical specification of the battery-(NiCd default:12mV, NiMH
default:7mV).
The screen shows the nominal voltage of lithium battery. There are
three types of lithium batteries: LiFe (3.3V), Li-ion (3.6V) and LiPo
(3.7V). It is critically importance that you set the charger in order to
check the type of battery you have. It will lead to damage the battery
and cause fire or explosion if failure to do so.

The battery becomes warm after cycles of charge and discharge. The
program will insert a time delay after each charge/discharge process to allow
the battery have enough time to cool down before starting the next cycle. The
valid value ranges from 0 to 60 minutes.
When charging begins, the integrated safety timer starts. If an error is
detected or the termination circuit cannot detect whether the battery is fully
charged or not, the program will help to prevent overcharging. Please refer to
the page below to calculate safety timer duration.
When the delta-peak voltage cannot be detected or the safety timer times
out, the capacity cutoff feature protects against overcharging the battery.
When the battery reaches the maximum capacity that the user set, charging
will be automatically terminated.
The charger beeps each time when you press a button. The beep or melody
sounds are to confirm different mode changes during operation. These
functions can be switched on or off.
This function monitors the voltage of the input battery used to power the
charger. If the voltage is lower than the value set by user, the program will be
automatically terminated to protect the input battery.
15

When charging NiCd or NiMH batteries, divide the capacity by current, then divide the result by
11.9. Use this as the number of minutes for safety timer setting. If the charger stops 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

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 of charging, 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, Lilo 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, press 'START/ENTER' key to make it blink
and then use '+' or '-' keys to change the value. Then press the 'START/ENTER' key again to
store the value.
