Sweeping pulse technology to optimize desulfation. Creates high frequency pulses and harmonics that both remove and prevent sulfation in 12 volt lead-acid batteries. Lead-Acid batteries are the workhorses of alternative power systems. They are efficient and low in cost. However, they are prone to the deposition of sulfate deposits on internal metal plates. These sulfate deposits ultimately diminish battery capacity and deteriorate battery longevity and health. The DS-1000 comes in 12V, 24V and 48V models (please specify). Handles 500 to 1200AH of battery bank capacity. Can be used to rejuvenate some apparently "dead" batteries. 3" x 3" x 1.5". Weight 0.6 pounds. 0.4W power consumption.
