The EnerSys ODYSSEY® Extreme Series Model ODX-AGM31 (engineering cross-reference code: 31-PC2150S) represents the pinnacle of industrial energy storage and engine starting performance, designed and engineered by EnerSys (USA). Built to withstand the rigorous field demands of military defense contracts and heavy commercial transport operations, this powerhouse delivers dual-purpose versatility in an all-in-one footprint: massive engine cranking bursts equivalent to dedicated starter batteries combined with continuous deep-cycling endurance down to 80% Depth of Discharge (DOD) without structural active material degradation.

The cornerstone of the ODYSSEY ODX-AGM31 design is proprietary TPPL (Thin Plate Pure Lead) technology. Unlike conventional automotive and industrial flooded batteries that utilize recycled lead-calcium or lead-antimony alloys, ODYSSEY plates are forged from 99.99% pure virgin lead and rolled into ultra-thin profiles. By dramatically reducing plate thickness, EnerSys engineers package significantly more active plates within the standardized BCI Group 31 envelope. This monumental surge in electrochemical reactive surface area allows the battery to discharge a staggering 2150 Amps of Pulse Hot Cranking Amps (PHCA) within the initial 5-second burst, backing it up with a true Cold Cranking Amperage of 1150 CCA to effortlessly ignite heavy displacement diesel powertrains under sub-zero arctic environments.

In addition to immense electrical output, the ODX-AGM31 (31-PC2150S) utilizes high-compression Absorbed Glass Mat (AGM) separators paired with flame-arresting Valve Regulated Lead-Acid (VRLA) safety pressure vents. The high-purity sulfuric acid electrolyte is completely absorbed into micro-porous fiberglass mats, yielding a 100% sealed, non-spillable structure that operates safely in any spatial orientation, prevents terminal post corrosion, and provides virtually maintenance-free operation throughout its service life. The rugged outer casing is molded from high-impact, flame-retardant thermoplastic polymer, safeguarding internal components against extreme vibrational stress and mechanical shock (meeting rigorous military-grade vibration standards). As a high-density stored chemical energy unit, the battery is handled under Dangerous Goods transport compliance (Class 8 Corrosive classification, UN 2800 Non-Spillable Battery exemption criteria), assuring dependable and secure deployment across demanding mission-critical facilities.
