utipower 400AH Intelligent Auto Pulse Battery Desulfator to Revive and Regenerate The Batteries for Lead Acid Batteries New Advanced Technology: dissolving sulfates WITHOUT DAMAGING THE BATTERY PLATES Auto-setting for 12-48v, Peak Amp: 4Amax Smart Battery Life Extender, Reduces Evaporation Rational Design: LED light indicates when pulse working Small & Lightweight: easy use, easy carry, cute appearance SPECIFICATION Working Amp :40mA max Peak Amp :4A max Peak Voltage :60-100V Pulse Frequency :10,000HZ Cutoff amp :5mA Voltage:12V,24V,36V,48V combined,manuall setting Remaks:LED light indicates when pulse working PRODUCT OVERVIEW Batteries often fail because sulfates slowly develop and cover the battery plates. This sulfating process also weakens the electrolyte and this combined with the gradual coating of the plates slowly and almost imperceptibly reduces the batterys ability to receive, store and then deliver power. This sulfating process gradually impairs battery function and causes a capacity loss until the battery can no longer perform the desired task and so the battery is deemed to have failed. FUNCTION The High-frequency Peak Pulse delivers an electronically controlled pulse to the battery causing crystalline sulfates to dissolve back into the electrolyte and so restoring battery function and electrolyte strength regaining the batteries ability to receive charging currentand deliver discharge current. ADVANCED TECHNOLOGY Many desulfator products use an old technology inductor design to generate the pulse to desulfate a battery. This old technology creates a harsh inductor peak that can be damaging to the battery plates. Utilising our new capacity pulsing method a soft peak is generated so dissolving sulfates without damaging the battery plates. Old technology also requires a large inductor so necessitating a physically large desulfator device whereas using our advanced technology design the Auto Pulse Desulfator device is very compact yet provides BIG performance.
