This is an eight-channel coin cell battery analyzer to analyze small coin cells from 0.001 mA to 10 mA, up to 5V. Each channel of the analyzer has independent constant-current and constant-voltage source, which can be programmed and controlled by computer software. This 8 channel coin cell tester provides most applications in battery testing fields such as electrode materials research, battery performance test, small-scale battery formation, capability grading, battery pack testing, etc.
