The PowerStar sets the industry standard for accuracy, efficiency, flexibility and reliability. Designed to recharge any 100% discharged lead-acid battery in its ampere-hour rating within 8 hours, the PowerStar is engineered to provide the maximum charging performance. Also available in 60% and 80% rated models.

The charger uses SCR power conversion circuitry, which is virtually maintenance-free, to provide years of dependable service. With the PowerStar, the battery determines its own charge cycle rate with its state of discharge. The PowerStar provides a constant current-constant voltage-constant current (I-E-I) charge curve to eliminate the possibility of overcharge, even with line voltage variations, and it completes the charge at the proper current regardless of battery age or specific gravity.
