We’ve been told that a 100AH battery is measured at 20A and means that it can run 20A for 5 hours, or 10A for 10 hours, or 1A for 100 hours. Did you know; that statement is not entirely accurate? In 1897 German scientist Wilhelm Peukert derived a formula that showed that the rate of discharge increases as the load increases Continue reading Analyzing battery run times
