Plug into 100-240V AC shore power for 3-stage charging, then rely on the built-in ACR to share alternator output between the start and auxiliary banks once you leave the dock. Battery temperature compensation, start isolation, and emergency parallel combine to protect your electronics and your batteries.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blue Sea Systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 7608\u003c\/li\u003e\n\u003cli\u003eDC output current: 20A\u003c\/li\u003e\n\u003cli\u003eNominal output voltage: 12V DC\u003c\/li\u003e\n\u003cli\u003eIntegrated ACR continuous rating: 170A\u003c\/li\u003e\n\u003cli\u003eOutput connections: 2 positive, 1 negative\u003c\/li\u003e\n\u003cli\u003eAC input: 100-240V AC, 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003eCharge stages: 3-stage (multistage)\u003c\/li\u003e\n\u003cli\u003eTypical float voltage: 13.5V DC\u003c\/li\u003e\n\u003cli\u003eTypical absorption voltage: 14.4V DC\u003c\/li\u003e\n\u003cli\u003eOperating current (no AC power): 10 mA\u003c\/li\u003e\n\u003cli\u003eACR combine voltage: 13.0V (2 min) and 13.5V (30 sec)\u003c\/li\u003e\n\u003cli\u003eACR open voltage: 12.75V (30 sec) and 12.35V if voltage is rising\u003c\/li\u003e\n\u003cli\u003ePlug style: NEMA 5-15P\u003c\/li\u003e\n\u003cli\u003eCompatible battery types: AGM, Flooded, TPPL\u003c\/li\u003e\n\u003cli\u003eRecommended minimum battery capacity: 100Ah (20h rate) per bank\u003c\/li\u003e\n\u003cli\u003eRecommended maximum battery capacity: 400Ah (20h rate) total of both banks\u003c\/li\u003e\n\u003cli\u003eTemperature sensor 1820 included\u003c\/li\u003e\n\u003cli\u003eLED remote indicator included\u003c\/li\u003e\n\u003cli\u003eWeight: 6.75 lb\u003c\/li\u003e\n\u003cli\u003eWarranty: 5 years\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eUniversal 12V DC dual-bank marine system.
