Its absorbed glass mat (AGM) construction keeps electrolyte locked inside, enabling spill-proof installation in a variety of vehicle positions. Low self-discharge makes it especially useful for seasonal equipment, and its vibration resistance and faster recharge characteristics help extend usable life in demanding driving conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow much starting power and capacity does the D51R provide?\u003c\/h3\u003e\n\u003cp\u003eThe D51R is rated at 12 volts with 450 cold cranking amps (CCA) for dependable starts in cold conditions and a C20 capacity of 38 amp-hours for reserve power.
