Battery internal resistance tester

1.The improved DC test method is adopted to ensure accurate measurement results and good repeatability.

2.The test data is automatically saved and will not be lost after power failure.

3.The product is small in size, light in weight, and easy to carry. It can be widely used in battery rapid detection, daily maintenance and battery pack installation engineering acceptance.


High precision lead Acid Intelligent Internal Battery Resistance Impedance Meter Tester


1.The improved DC test method is used to simulate the actual use of the battery and automatically filter out the influence of charger’s ripple, electromagnetic interference and battery’s capacitive reactance and can test the battery in high noise environment with true and correct measurement data. Meanwhile, it can be used both online and offline;

2.It has constant current discharge, high measurement accuracy and good retestability, and the built-in “filtering circuit with floating charging current” is not affected by floating charge current;

3.With special test clips, it truly achieves “four-wire” measurement with accurate measurement results, good repeatability and high consistency, and both hexagonal and outer hexagonal bolts are applicable;

4.Floating charge voltage, battery internal resistance and connecting resistance can be measured simultaneously at one time;

5.It can automatically judge whether the connection is correct, gives prompts, and has the functions of reverse connection, wrong connection and over-voltage protection;

6.With self-diagnosis and self-calibration function, it automatically eliminates zero deviation and ensures the accuracy of measurement;

7.With built-in memory, it can save 300 pcs. / group × 10 sets of measurement data without power loss;

8.It has wide measurement range and is compatible with all types of battery specifications such as 2V, 4V, 6V and 12V; 9.With built-in high-capacity rechargeable lithium battery, it can work continuously for more than 10 hours;
