How Does the Duracell Ultra Battery Perform in Marine Environments?

Engineered for harsh marine conditions, the Duracell Ultra BCI Group 24M resists corrosion and vibrations. Its AGM technology prevents acid spills, even at extreme angles, while 750 marine cranking amps (MCA) ensure quick starts. Tests show 20% longer runtime in saltwater compared to flooded lead-acid batteries.

Saltwater exposure tests demonstrate the battery’s reinforced terminals maintain 95% conductivity after 500 hours of salt fog exposure – 35% better than standard marine batteries. The compression-sealed case withstands 30 psi impacts without deformation, crucial for rough water conditions. Field reports from Florida charter captains show 98% reliability in tropical environments across 3-year deployments.

Why Choose AGM Technology for Deep-Cycle Applications?

Absorbent Glass Mat (AGM) technology enhances safety and efficiency by immobilizing electrolytes in fiberglass separators. This allows faster recharge (40% quicker than gel batteries), zero maintenance, and vibration resistance up to 5G. Duracell’s AGM design achieves 98% recharge efficiency vs. 85% in flooded batteries.

The dual-layer glass mats contain 2.5x more electrolyte saturation points than standard AGM designs, reducing internal resistance by 18%. This enables 1,200A pulse currents for windlass operation without voltage sag. Unlike gel batteries that degrade at high currents, Duracell’s AGM maintains stable performance between -40°F and 176°F. Third-party testing confirms 92% capacity retention after 18 months of daily 50% discharge cycles.

What Sets Duracell Ultra Apart from Competitors Like Optima?

“The Duracell Ultra’s thick plates and high-density active material make it exceptional for frequent deep discharges. Most users don’t realize AGM batteries lose 15% capacity if stored below 12V for months—always use maintenance charging.”

FAQs

Can this battery power a 2000W inverter?

Yes, for 1-2 hours. At 2000W/120V = 16.7A, the 120Ah battery lasts ~7.2 hours at 50% DoD. Use two in parallel for extended runtime.

Is the Duracell Ultra compatible with solar charging?

Yes, works with PWM/MPPT controllers. Set absorption voltage to 14.4-14.6V and float at 13.5V. Maximum solar input: 100A.
