Abstract
A method and apparatus is provided for rapidly and safely estimating the high-rate load test voltage of a storage battery utilizing open-circuit voltage, temperature and a dynamic parameter such as conductance or resistance. An output indicative of the condition of the battery is provided as a function of the estimated load test voltage of the battery compared to industry standards without the necessity to charge the battery or discharge the battery with high-rate loads using bulky load testing equipment.
