Battery Yellow Top H7 880CCA/1000CA Model DH7

The OPTIMA Battery Yellow Top H7 880CCA/1000CA Model DH7 is a 12-volt AGM (absorbed glass mat) battery engineered for vehicles with high electrical demands, dual battery systems, and auxiliary power installations. Delivering 880 cold cranking amps (CCA) and 1000 marine cranking amps (MCA), this battery provides robust starting power in demanding conditions—from off-road recovery operations to extended field deployments where reliable engine start and sustained electrical draw are mission-critical.

Built with OPTIMA's proprietary spiral-cell AGM technology, the Yellow Top H7 resists vibration, handles deep cycling better than standard lead-acid batteries, and offers superior reserve capacity for sustained auxiliary power. The 880 CCA rating ensures dependable cold-weather cranking, while the 1000 MCA specification reflects performance in marine and moisture-heavy environments. At 63.3 lbs with dimensions of 12 × 9.5 × 15 inches, this battery fits standard Group H7 applications. AGM construction eliminates the need for water maintenance and reduces spill risk—a key advantage in tactical vehicles and equipment where durability and safety matter.

This battery is purpose-built for operators who depend on auxiliary systems—communications equipment, lighting, winches, and mobile command stations—alongside conventional starter duty. Dual-battery setups common in overland vehicles, emergency response units, and tactical support vehicles benefit from the Yellow Top's ability to handle both starting and cycling loads without premature failure. The robust construction and vibration resistance prove invaluable in high-impact terrain and repetitive operational stress.

The OPTIMA Yellow Top H7 represents a category of dual-purpose batteries that bridge the gap between traditional starter batteries and deep-cycle designs. Serious users seeking reliable power in vehicles subjected to heavy electrical loads, harsh environments, and extended field operations recognize the value of AGM technology and OPTIMA's established market position in performance battery applications.
