Extech BT100 Battery Capacity Tester User's Guide
The Extech BT100 is a battery capacity tester designed to measure the internal resistance and output voltage of lead storage cell, nickel-cadmium, lithium-ion, and nickel-metal hydride batteries. It utilizes an AC four-terminal method with a 1kHz test current to eliminate lead resistances and contact resistances for accurate results.
The device features a dual display that simultaneously indicates internal resistance and voltage, along with a comparator function capable of storing up to 99 sets of values. Users can perform manual data logging for up to 999 sets or continuous interval datalogging for up to 9600 points. The unit includes an RS232 PC port compatible with Windows software for data analysis.
