Product Description: Battery internal impedance, also known as internal resistance, is a key indicator of battery performance. Testing the internal resistance of a battery to determine its power supply capacity has been a common understanding in the industry. Factors affecting the internal resistance of the battery are: battery size, working time, structure, condition, temperature and charging status.
Product features:
1, can test the battery voltage, internal resistance, capacity;
2, can be used as a voltmeter, test battery voltage;
3, the battery of different voltage levels can be automatically switched;
4, the capacity of the battery can be measured;
5. Test data synchronization storage;
6. Sound prompt for discriminant results;
7, battery charging status indicator;
8. Real-time display of battery voltage;
9, no operation automatic standby;
10. Test data record storage;
11, through the U disk and analysis software system for data exchange.
