WARNING AND SAFETY NOTES
There is a 3-pin port on the left of the charger used as USB interface of temperature sensor port. If the
screen displays temperature, you can use the optional temperature probe to connect to the surface of
the battery. If it is set as the USB port, you can connect the charger to your PC through the optional
USB cable to monitor the charging process through optional software.
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).
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 1to 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 overcharg-
ing. Please refer to the below statement to calculate the timer you set.
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.
The beep to confirm users' operation sounds every time a button is pressed.
The beep tor 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 protect
the input battery.
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 safetl 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

SAFE TIMER CALCULATION
Lithium (LiIo/LiPo/LiFe) program
The program is only suitable for charging/discharging Lithium-polymer batteries with a nominal
voltage of 3.3/3.6/3.7/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, LiIon 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 DES or INC to change the value. Then press START/ENTER key again to
store the value.
