Charge mode
Constant current and constant voltages are the main mode. Active charge and pre-charge are available according to different battery voltage.
Active charge
Tester may not recognize 0V-battery. Users should press the charge key to start up the active charge function. Being activated and going to normal charging status, when the battery establishes communication with the tester.
Pre-charge
Battery goes into pre-charge status when voltage of battery under setting pre-charge voltage.
Constant current charge
Battery goes into fast charge status when voltage of battery over setting pre-charge voltage. Fast charge time relates to the battery design capacity and fast charge current.
Constant voltage charge
Battery goes into constant voltage charge, when battery voltage up to battery saturation voltage, now current will be decreasing by battery saturation voltage
End of charge: When the current reduced to terminate current, Or e capacity reaches 100%
Charge current
3000mA Max, set by CHARGE function
Battery testing
Testing battery charge and discharge function is good or bad,test time set by user, according to user demand, can set by BT.TEST item. Test passed will display “OK” otherwise display “NG”
