It's an ideal fit for equipment that can't run a series pack and needs one battery to do the heavy lifting.\u003c\/p\u003e\n\u003cp\u003eAt 308Ah and 169 lbs, this is the top of U.S. Battery's single-battery 12V AGM lineup — bigger than the 4D, and the option to reach for when even a 4D's 246Ah isn't enough and you still need everything running off one battery rather than a series-wired bank. That capacity comes with real installation planning: at this weight, it's a two-person job and the compartment needs to be built to hold it securely.\u003c\/p\u003e\n\u003ch3\u003eWhy choose the US AGM 8D\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e308Ah — the largest single-battery capacity in U.S. Battery's 12V AGM lineup\u003c\/li\u003e\n\u003cli\u003eF14 terminal for heavy-duty wiring connections\u003c\/li\u003e\n\u003cli\u003eOne battery instead of a series bank for equipment that needs single-unit capacity\u003c\/li\u003e\n\u003cli\u003eSealed, non-spillable AGM chemistry — no watering, no acid spills\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eUS AGM 8D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e12V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacity (20HR)\u003c\/td\u003e\n\u003ctd\u003e308Ah\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacity (5HR)\u003c\/td\u003e\n\u003ctd\u003e252Ah\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReserve Capacity @75A\u003c\/td\u003e\n\u003ctd\u003e180 min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReserve Capacity @56A\u003c\/td\u003e\n\u003ctd\u003e262 min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReserve Capacity @25A\u003c\/td\u003e\n\u003ctd\u003e728 min\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e20.5in (521mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e10.6in (268mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e8.86in (225mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e169 lbs (77kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal\u003c\/td\u003e\n\u003ctd\u003eF14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Material\u003c\/td\u003e\n\u003ctd\u003eABS, Heat Sealed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Type\u003c\/td\u003e\n\u003ctd\u003eSealed AGM, Valve-Regulated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003e\u003cem\u003eBacked by U.S. Battery's manufacturer warranty.
