This's an eight-channel battery analyzer to analyze small coin cells and cylindrical batteries from 5.0 mA to 6000 mA, up to 5V, with gold-plated pins for the best connection. Each channel of the analyzer has independent constant-current and constant-voltage source, which can be programmed and controlled by computer software. This system provides most applications in battery testing fields such as electrode materials research, battery performance test, small-scale battery formation, capability grading, battery pack testing and etc.
