WebProduct Highlights. The BT2152B Self-Discharge Analyzer measures self-discharge current of Li-Ion cells providing a revolutionary reduction in the time required to discern good vs bad cell self-discharge performance, and dramatic reductions in cell manufacturing WIP WebA power analyzer is an instrument that measures and quantifies the rate of power flow in electrical systems. Power flow is expressed in Joules/second (J/s) or kilowatt-per-hour (kW/h). Electrical power is the rate per unit of time that electrical energy is transferred in an electrical system between two points.
