VMAX XTR31-135 12V 135AH Vmaxtanks AGM Sealed Deep Cycle 12V 135AH 800CCA Deep Cycle Group 31 Battery

The VMAX XTR31-135 is part of the "Extreme" series, engineered with military-grade alloy plates and 100% virgin lead. Unlike standard Group 31 batteries that compromise between starting and cycling, the XTR31-135 excels at both. It delivers a massive 1150 CCA to turn over large engines instantly, while its 135Ah capacity provides a class-leading 265 minutes of Reserve Capacity for your electronics and trolling motors. Why Pros Choose the VMAX Xtreme Series: * Dual-Purpose Performance: One battery handles both high-surge engine starts and long-draw deep cycle applications. * Extreme Vibration Resistance: Built with tightly packed plates and thick ABS casing to survive the constant pounding of heavy waves or off-road travel. * Zero Maintenance: Sealed AGM design is 100% leak-proof and spill-proof. No water to add, no acid leaks, and safe to mount in any position. * Long Service Life: Designed for 10-12 years in float applications and up to 1,000 cycles at 50% discharge. * BCI Group Size: 31 * Cranking Power: 1150 CCA / 1500 MCA * Energy Density: 1.8 kWh of reliable power * Weight: 78 lbs of heavy-duty lead (indicates superior plate thickness) * Terminals: Versatile Dual Setup (SAE Automotive Posts + 5/16" Stainless Steel Studs)

• MONSTER CAPACITY: Boasts a massive 135Ah (20-hour rate) and a 265-minute Reserve Capacity. This is designed for high-thrust trolling motors (55lb-80lb+) and power-hungry fish finders.
• DUAL-PURPOSE POWER: With 1,150 Cold Cranking Amps (CCA) and 1,500 Marine Cranking Amps (MCA), it delivers the high-surge current needed to start large outboard engines while still providing true deep-cycle endurance.
• MILITARY-GRADE BUILD: Constructed with heavy-duty lead-tin alloy plates and 100% virgin lead. This provides 2x the cycle life of standard Group 31 batteries and superior performance in extreme heat or cold.
• VIBRATION BATTLE-READY: The Xtreme Series features extra-thick plates and tightly packed separators, making it virtually immune to the heavy pounding of waves and high-speed boat vibration.
• PLUG-AND-PLAY TERMINALS: Equipped with dual terminals (SAE Automotive Posts + 5/16" Stainless Steel Studs) for versatile and secure connections to any marine or RV setup.
• Terminals: SAE POSTS + 5/16” STUDS
• MCA(Marine Cranking Amps): 1500A CCA (Cold Cranking Amps): 1150A
