U.S. Battery Manufacturing’s AGM 8D deep-cycle, maintenance-free battery is designed to increase runtime and service life for marine applications where reliable power is always needed. This 8D group sized, 12-volt battery measures 20.5’ (521mm)L x 10.6” (268mm)W x 8.86” (225mm)H and has been designed to fit in tight compartments and can’t be easily accessed for routine or frequent maintenance required for deep-cycle Flooded Lead batteries.
The US AGM 8D deep-cycle battery has a 308 amp-hour rating at a 20-hour rate, with a runtime of 262 minutes at a 56-amp draw. This performance delivers the power your boat’s accessories need to run longer and reliably, powering everything from lights and troll motors to keeping your satellite and emergency communications equipment working during long voyages. The battery’s internal structure features thick positive alloy grids for exceptional corrosion resistance, high-density positive active material, and advanced glass mat separators. These components work together to maintain the battery cell structure during deep-cycling, limit acid stratification, and inhibit internal shorts. The batteries also feature carbon-enhanced negative active material that improves charge acceptance and cycling performance. In addition to vibration resistance and maintenance-free valve-regulated operation, the battery is one of U.S. Battery’s latest AGM designs that are engineered to improve reliability, overall performance and deliver a longer cycle life.
With a heat-sealed, heavy-duty, red ABS case, the US AGM 8D can handle working in harsh environments and comes with an F14 insert style terminal; an optional screw-in SAE terminal post is also available. More information on the US AGM 8D is available by downloading the battery’s datasheet.
