Automatic Car Battery Charger Smart Fast Power Charging + Acid Digital Plug. Features: This is An automatically car Battery Charger which Can Charing the Battery Based on Battery's Condition It Uses the MCU Controller for Save & Fast Charging Service for Your Battery Constant Current Mode: When the Voltage of the Battery is Lower Than the Value Set by the Charger, the Charger Will Work Under the Constant Current Mode and Supply the Constant Current for the Battery. Constant Voltage Mode: Using the Pulse Width Modulation(PWM) Tech to Control the Charging Current and Output Voltage of the Charger Which Ensures the Battery is Fully Charged and Avoids over Charging. Floating Charge Mode: When the Voltage of the Battery is Approaching the Value of the Constant Voltage Mode, and the Current Will Cut Down to the Given Current Gradually, That Means the Battery Power is Full, then the Pilot Lamp Will Turn Green and the Fan Will Stop Working. The Charger Will Turn the Mode into Floating Charge Mode Automatically. At This Moment, the Battery Can Be Stopped Charging or Keep on Floating Charge for Half an Hour.   Evaporation Function Automatic Trickle Function Anti-anti-charging Function Anti Overvoltage Overcharge Function Power and Energy Short Circuit Protection Short Start Function Overcharge Wide Voltage Range LCD Display  US Plug Charger Mode: Three-phase (PWM Charging Mode) Includes Constant Current Charging Phase, Constant Voltage Charging Phase,floating Charging Phase   Specification: Fitmnet: for Car Motorcycle Materials: Plastic + Metal Battery Type: Storage Battery AC Input Applicable Battery: 12Ah-100Ah Charger Current: 6A Input Voltage: 150V-250V Output Voltage: 12V Rated Frequency: 47-63HZ Full Load Efficiency: 87% Working Temperature: -40~+95 ° Size: 21*6.5*12cm Package Weight:230g  Package Included: 1 X Battery Charger 1 X User Manual .
