12.8 V battery ORANGETOP™ Q31M-DP120

lithiumionwaterproof

Dual-purpose battery for both engine-starting and deep-cycle applications Powerful engine cranking power, up to 1200A Meets or exceeds Nov. 2022 Mercury specifications for lithium-ion engine starting batteries. High capacity, long-lasting performance with 120Ah, 120% the capacity of most GR31 batteries. Industry-leading communications via NMEA 2000 and Bluetooth app that displays battery status. Advanced microprocessor-controlled battery management system (BMS) automatically monitors and controls all functions. BMS-balanced cell state of charge for improved performance and extended life span. Battery-to-battery communication maximizes charging, equalization and performance. QUAD terminals for easy installation of accessories. Robust design with industry-leading vibration, dust and water resistance. Integrated protection from alternator "load dump" in the event of BMS disconnect. A lithium charger, or lithium charging algorithm, must be used for charging lithium batteries. Fitment Cross Reference: Gr 31 max starting current (10 seconds): - 1200A starting current (20°f, 8 seconds): - 800A max charging current (continuous): - 120A operating/discharge temp limits: - -4F to 131F (-20°C to 55°C) charging temp limits: - 32F to 113F (0°C to 45°C) A HISTORY OF INNOVATION With a 40-year history of technological innovation and engineering, OPTIMA® products offer unstoppable power for extreme enthusiasts and others who require THE ULTIMATE POWER SOURCE.
