Automatic charger/discharger can active any disabled single cell battery of 2V/6V/12V or activate the disabled battery of 1-24 section. It can increase disabled single cell capacity and battery life so that prevent broken battery hurt normal battery. Integrating charge and discharge in one, it can automatically achieve charge and discharge process constant voltage and constant-current after setting parameter.

1. Display mode: LED display all parameters and test data in real-time with English menu. Display testing data: voltage, current, capacity charging time, discharging time etc.

2. Control pattern: Keyboard set all parameters: even charging voltage, under voltage protection, charging/discharging current, charging/discharging capacity charging /discharging time.

3. Operating mode: (1) Constant current discharging achieve the capacity test and load capacity test of the battery. (2) Intelligent three stages charging: Constant current-fixed voltage, reducing current-floating charging.

4. Automatic stop: It can stop testing automatically meet following conditions: test time out, testing capacity out, Over-current protection value and protective voltage out.

5. Automatic alarm function: When meet high temperature, opposing connection, battery wire disconnect, undervoltage, overvoltage, overcurrent, it will give a alarm.

6. Calibration correction function: Calibrate the charging/discharging voltage, charging/discharging current.

7. Modular design: Small size, convenient to carry, forced air cooling.
