The BT100 Battery Capacity Tester is designed for measuring the internal resistance and output voltage of batteries including lead storage cell, nickel-cadmium battery, lithium-ion battery and nickel-metal hydride battery. It adopts AC four-terminal method to eliminate lead resistances and contact resistances, yielding the most accurate results. It has a 1kHz test current with up to 10µΩ resistance resolution and dual display to simultaneously indicate the internal resistance and voltage of the battery. The tester also features a comparator function with storage of up to 99 sets of resistance and voltage values for battery deterioration characterization. It comes with pin type and alligator type 4-terminal Kelvin leads for quick and accurate resistance measurements. The memory capacity can store up to 999 manually stored data points or up to 9600 points stored using interval datalogging. It is equipped with an RS232 PC port and Windows compatible software.
