VMAX XTR8D-310 Group 8D Deep Cycle AGM Battery – 310Ah / 1200 CCA

Product Description

310Ah AGM Group 8D Battery

The VMAX XTR8D-310 12V deep cycle marine battery delivers true dual-purpose AGM performance, combining 1,200 cold-cranking amps with a 310Ah deep-cycle capacity in a standard Group 8D case. It’s built for applications that need both strong starting power and long, reliable runtime—without a compromise. Engineered using VMAX’s military-grade AGM construction, the XTR8D-310 features thick internal plates, tightly packed separators, and a sealed, maintenance-free design. The result is excellent vibration resistance, high output, and durability that holds up in the toughest environments.

Features & Benefits

• High Cranking Power – 1,200 cold cranking amps ensure reliable starting power in all weather conditions.
• 310Ah Deep-Cycle Capacity – Designed for frequent deep discharges without loss of capacity.
• AGM Construction – Heavy-duty plates with Absorbed Glass Mat separators for extreme durability.
• Heavy Vibration Resistance – Rugged construction ideal for marine, RV, and industrial environments.
• Group 8D – Replaces Interstate 8D-XHD & NAPA 7269 batteries plus many others. Cross-Reference
• Low Self-Discharge – Maintains a charge longer between uses than conventional flooded batteries.
• Temperature Tolerant – Dependable starting power in both high and low temperatures.
• Dual Terminal Design – 3/8″ Studs + SAE Automotive Posts provide versatile connections.
• Built for Commercial Use – VMAX takes pride in building Tough Batteries for Tough Applications.
