Abstract
A portable measurement device and method for measuring a parameter value of a battery. The measurement device connects a large resistive load to a battery being tested. The load is connected to the battery through a first set of kelvin connected clamps and a switch. A microprocessor measures open and closed circuit voltages via a second set of kelvin connected jaws. The microprocessor determines voltage drop curve data based on the measure open and closed circuit voltages. The microprocessor compares the voltage drop curve data to voltage drop profile data for a particular parameter to determine the parameter value for the battery.
