The PowerStar Plus meets the highest standards for accuracy, efficiency, flexibility and reliability. Designed to recharge batteries from 20% state of charge to 80% state of charger in 3 hours or less. The charger uses SCR power conversion circuitry, which is virtually maintenance free, providing years of dependable service. With the PowerStar Plus, the battery determines its own charge rate based on its state of discharge, electrolyte temperature, and battery age. The charger provides a constant current-constant voltage-constant current (I-E-I) charge curve to eliminate the possibility of overcharge, even with the line voltage variations, and it completes the charge at the proper current regardless of battery age or specific gravity.
