Waste Time
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 1 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.
Capacity Cut-Off
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.
Key Beep / Buzzer
The beep to confi rm users’ operation sounds every time a button
is pressed. The beep or melody sounds at various times during
operation to confi rm different mode change. These functions can be
switched on or off.
Input Power
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.
Safe timer Calculation
When charging NiCd or NiMH batteries, divide the capacity by cur-
rent, 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
User settings and menu’s
As default this charger will be set to typical user settings when it is connected to a 12V battery
for the fi rst 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
