Product Name: Ultipower 12V8a SLA Battery Charger Model NO.: UBC-2-1208 Principle: Switchmode Charging Type: Electric Charger Type: Lead-Acid Battery Charger Input Voltage: 85-250VAC Charging Current: 12V8a Rated Power: 12V-150W Safety: Polarity Protection, Short Curcuit Charge Mode: Fully Automatic Technology: Reverse Pulse High Tech Revive Battery Compact: 0.72kg Display: Digital Display Function: Desulfation Function Feature: Intelligent Control&Maintenance Certification: Ce RoHS Trademark: UltiPower Transport Package: Carton Origin: Jiangsu Province of China HS Code: 8504409992 Product Description 12V8A SLA battery charger1. Latest reverse pluse tech reviving batt.2. Smart control&maintenance3. Polarity &overcharge protection4. Fully Automatic charging5. Desulfation function6. Digital displayUltipower 12V 8A smart scooter charger with desulfationFeatures:Adopting switch mode design, reverse pulse technology and MCU (micro control unit) system, the chargers are more compact, reliable and advanced. The most important is the reverse pulse technology.Switch mode:Or we call Switching Power Supply, this is different from Linear Power (using in traditional charger).1. Conversion efficiency:More than 85% electric energy was transferred to battery chemical energy during charging process comparing with 40% of conventional charger.2. Compact:Net Weight: 0.72kgMCU system:1. Automatic charging1). Multi charging procedures2). Monitor the whole charging process3). Polarity & overcharge protectionPrevent the output leads from sparking due to accidental reverse connection or short circuit, never worry about overcharging.Reverse Pulse Technology:Combined with MCU system, chargers generate reverse pulse current during the charging process.1). Reducing battery internal impedance, gassing and temperature rise, restore the sulfate into liquid to recover battery capacity.2). Maintain battery, extend battery' service life and keep battery in shape...3). Low temperature rise and save energy.This will helps you to cut considerable costs on battery maintenance.Besides, all chargers have digital display.Digital Voltmeter, Ammeter and thermometer will show battery' voltage, current and charger's temperature on battery.We have CE & RoHS certificationFull range of ur product line: 6V-72V, 600mA-50A.
