What can Kongter do?

Regular maintenance and test is a " must-have" procedure for standby batteries. It is also recommended by IEEE latest standard for maintenance and testing of standby batteries. the excellent performance of BT-3915 for testing cell internal resistance/conductance and voltage will help you eliminate the weak batteries and ensure their performance.



- Two-in-one: switchable between internal resistance and conductance measurement

- Wide test range: 5~6000Ah, compatible for cell of 1.2V, 2V, 6V and 12V

- Smart and portable hand-held device, rugged and easy-to-go

- Colorful touch screen with optional operations of keyboard and touch screen

- Simultaneously test voltage and internal resistance/conductance

- Fast testing for battery and string in seconds with testing data auto saving

- Strong anti-interference in high current with stable and accurate performance  

- Low testing frequency, effectively avoid interference from capacitive resistance

- Direct USB drive for software update and data transfer to computer

- Powerful PC management software, convenient for data storage and analysis

- Big memory for testing data storage of more than 3000 cells  

- Buzzer alarm function and over voltage protection

- Auto-calibration function before testing enhances the testing accuracy

- Build-in reference value and self-defined value for comparison of testing result

- Retest and compensation function: any faulty operation or omission could be retested simply with one click

- Optional function: can wirelessly transfer data to IT system via GPRS model
