OPTIMA BLUETOP Marine Batteries
OPTIMA BLUETOP Marine Battery: The BLUETOP starting battery (dark gray case) is to be used when a dedicated starting battery is required; it should never be used for cycling duty. The dual-purpose BLUETOP (light gray case) can be used for both starting and deep cycling; it is a true deep-cycle battery with extremely high cranking power.

Also use for:
  • Trolling motors, marine applications with heavy electrical accessories and RVs should use a dual-purpose BLUETOP (which is both a starting and deep-cycle battery)
  • Marine applications and RVs when the battery’s only function is engine starting
Key Benefits
  • Both dual-purpose and starting applications available
  • Up to 3x more recharges than other marine batteries
  • More than 15 times the vibration resistance
  • Spill-proof
  • Mountable in virtually any position
  • Maintenance-free
  • Optimal starting power (dual purpose and starting applications available)
  • Works well as a boat battery or RV battery
The OPTIMA model number for this battery is D31M. If you are replacing an OPTIMA battery you already have, this model is the same as batteries marked 8052-161, 9052-161, 27931, D31M-1125, BLUED31M, 27551, SC31DM, or N99D31MBLUE.

Warranty: 2 years private use, all OPTIMA® have their warranty details on the top label and are honoured by the warranty stated on that label. 

Why choose OPTIMA batteries?
OPTIMA batteries are the choice among performance enthusiasts who want to add more power to their adventures. Thanks to proprietary SPIRALCELL TECHNOLOGY, these batteries are more than 15 times more vibration-resistant, which means they can take a lot of abuse both on and off the road, and provide up to three times the life of a traditional flooded battery.

OPTIMA battery grids are constructed of 99.99% pure lead. The purity of the lead provides lower internal resistance for additional power and quicker recharging, corrosion resistance for longer life and reduced self-discharge when stored on the shelf.

OPTIMA's tightly coiled Absorbent Glass Mat (AGM) separators hold electrolyte like a sponge to eliminate acid spilling. Each maintenance-free battery is also completely sealed, preventing corrosion and acid spills.

Note: The difference between BLUETOP and YELLOWTOP deep-cycle batteries is that BLUETOP batteries have both automotive (SAE) posts and threaded studs, while YELLOWTOPS (other than D31T) only have SAE terminals.
