Introduction

When you're out on the water or hitting the open road, the last thing you want to worry about is your battery's performance. The Optima D31M BlueTop Marine Battery is engineered to deliver exceptional power, longevity, and reliability for both marine and recreational vehicle (RV) applications. This dual-purpose battery combines high cranking power with deep-cycle capability, ensuring that you have the energy to start your engine and run all your onboard electronics without a hitch.

Key Features and Benefits

Dual-Purpose Functionality

• Starting Power: With a robust 900 Cold Cranking Amps (CCA), the D31M provides reliable engine starts even in cold weather conditions.
• Deep-Cycle Capability: Designed to handle numerous deep discharge and recharge cycles, making it ideal for powering trolling motors, fish finders, GPS systems, and other onboard electronics.

SpiralCell Technology

• Enhanced Performance: Utilises Optima's proprietary SpiralCell design, featuring spiral-wound cells made from pure lead plates coated with lead oxide. This results in a cleaner, stronger power source compared to traditional flat-plate batteries.
• Extended Battery Life: The innovative construction reduces internal resistance and maximises output, contributing to a longer service life.

Maintenance-Free Operation

• Convenience: Completely sealed and spill-proof, eliminating the need for regular maintenance like adding water.
• Versatility: Can be mounted in virtually any position (except upside down), offering flexibility in tight or uniquely shaped compartments.

Superior Vibration Resistance

• Durability: Fifteen times more resistant to vibration than conventional batteries, ensuring it withstands the rigors of rough seas and off-road terrains.
• Reliability: Less susceptible to damage from wave impacts or bumpy rides, providing consistent performance over time.

Fast Recharge Capability

• Efficiency: Recharges faster than traditional batteries, reducing downtime and allowing you to get back to your activities sooner.
• Productivity: Ideal for applications that require frequent battery use and recharging cycles.

Environmental Resilience

• Temperature Performance: Operates effectively in extreme temperatures, both hot and cold, ensuring dependable power in all climates.
• Moisture Resistance: The sealed design protects against moisture and humidity, common challenges in marine environments.
