HDGC3985 Battery Discharge Charge Tester

General information

Battery Discharge Charge Tester is mainly used for the charge test of the lead-acid battery of the backup power supply in the telecommunications, mobile, substation, railway transportation and pertrochemical industry power DC industries. It can proceed the discharge and charge for the batteries to extend the lift-time .



● PTC ceramic resistor is adopted to avoid the red heat phenomenon for a safer discharge process .
● Cell monitoring module is performed the voltage commission by remote radio wireless communication mode, it can set up to four unique frequency brands.
● Wireless acquisition box can monitor each cell for monitoring the whole process of battery series .
● PC software can record and analyze total voltage, discharge current ,cell voltage and other data , generate the data report . it can virtually reflect battery serious performance curve, diagram and report for printing and searching .
● Connected with USB interface,the data of the discharge process can be record to U disk and transformed to PC by U disk .
● Intelligent SCM ARM control, 7inch 1024*600 LCD screen
● Automatic self-protection stop function, over-heat protection ,over voltage protection , over current protection and reverse connection protection ,alarm prompt is displayed on the screen .
● It can set charge/discharge termination condition including cell low voltage,whole group voltage low/high, charge current low, charge/discharge time , charge/discharge capacity .
● It can perform on-line compensated charge/discharge, and can also carry on discharge test for on-line working storage battery by connection external current clamp sensor.
● RS485 remote control charge , discharge and activation functions .
● It has the function of charge, discharge and activation with muti machine parallel mode by only operating in the display screen of the parallel instrument with parameters as the master.
