Detailed Description

Summary RFNT3 is a multi-function battery testing device, having the features below: 1)With one channel, supporting one intelligent battery 2)Supporting charge, discharge, test, capacity correction, charge / discharge 50% capacity 3)LCD for displaying battery informaiton 4)LED for indicating working status 5)With charge-key, discharge-key, backlight-key and function-key 6)Pre-charge, fast charge and constant voltage charge for charging stages and the variation range of the values of the constant current and the constant voltage is less than 1% 7)Constant current for discharging 8)With a USB port for connecting with computers, master machine can monitoring and control slave machine Basic Parameters Dimensions: 201 x 99 x 35 mm Weight: 333g Adapter Input: AC 100 ~ 240 V Output: DC 24V 2.65A Display mode Segment LCD with white backlight + LED in red and green Discharging mode Constant current discharge for double loads, inner load & external load Maximum charging current: 3A Charging mode Constant current and constant voltage are the main mode. Active charge and pre-charge are available according to different battery voltage. Standby power consumption ≤1W Time Time limit for charging: 8.8h Time limit for discharging: 8.8h Time limit for testing: 20s + 10s = chg + disc Time limit for capacity correction: 8.8h + 20s + 8.8h = disc + pause + chg Auto quit time for function menu: 10s Function Introduction Charge Active, pre-charge, constant current and constant voltage are the stages of charging mode. The initial charging mode depends on the battery voltage, so active and pre-charge don't happen to every batteries. Discharge Constant current discharge for double loads Inner load: 0 ~ 1000mA, adjustable continuously via Battery Manager default discharging current = 500mA External load: 0mA, 500mA, 1000mA, 1500mA, 2000mA, five gears with dip switches offered Tester will stop discharging if one of the conditions below is met. Test Testing time is 30 seconds and the purpose is to check both the charging and discharging performances. After finishing test, LED flickers with green colour and LCD reports the test result. Normal: Test OK Shown on LCD Abnormal: Test NG Shown on LCD Capacity Correction The battery capacity value in the battery management chip will different from the actual capacity after a battery goes through many recycling cycles. It will affect the use of the battery when the difference reaches a certain degree. Capacity correction is to deep discharge a battery and then fully charge, which will correct the capacity value in the battery management chip. 50% Capacity CD50%: charge firstly, and then discharge to 50% capacity DC50%: discharge firstly, and then charge to 50% capacity Online Functions Tester can be connected with master machine via a USB port. Users can monitor, control and set parameters via Battery Manager software in the master machine. Others Active cooling Active batteries of zero voltage When a battery is deep discharged, the discharge protection circuit will start up and the voltage in the battery connector will become zero voltage. In this case, an appropriate voltage should be supplied to active the battery. Battery identification Battery information can be read from battery management chip after establishing communication. Intelligent protection Against over-current, over-voltage, over-charge, over-heat and short circuit. Fan Discharging mode: fan startup Other modes: fan startup when temperature above 48℃ fan stop working when temperature below 40 Trouble alarm LED flickers in red colour and current command stops when one of the conditions below happen. △ There is not current for around 50 seconds when charge. △ There is not current for around 25 seconds when discharge. △ Charging time is above 8.8 hours. △ Discharging time is above 9.9 hours. ◇ Suitable for almost all laptop batteries, above 95% Accessories ◇ 1 x load ◇ 1 x adapter ◇ 1 x USB cord ◇ 1 x CD ◇ 13 x connectors ◇ 10 x cables ◇ 10 x jumpers
