Hawk Helmets Tech 12V Automatic 7-Stage Battery Charger with Smart FunctionSmart Automatic Battery Charger plus Maintenance & Recondition FunctionFor 12V Lead - Acid Battery by 7-Stage Charging ProcessFeatures & Spec: Perfect for all lead-acid, flooded or sealed maintenance free batteries (AGM and gel cell). Complete 7-Stage Charging Process (initialization, soft start charge, bulk charge, absorption mode, analysis, recondition, and float mode). Automatically switches to float / maintenance voltage after fully charging the battery. If the battery voltage drops too far under load, full charger output power resumes. Temperature compensated to ensure optimum charge voltage according to ambient temperature. Lower battery voltage start to charging, can charging any severely discharged or heavily sulfated battery. Battery voltage analysis, recondition battery automatically. Solid state two color LED indicates stage of charger. Spark proof and reverse polarity protected. Includes quick connect harness for use in hard to reach areas. Input voltage range: 100-240Vac Input frequency: 50/60Hz Output voltage: 12V Output current: 2000mA Size (L x W x H) in mm: 149 x 71 x 32 Weight: 0.45Kg Safety and EMC standard: CE,SAA,UL,FCC,CEC
