Sun Xtender PVX-2580L 12V 258Ah Solar Battery - VRLA AGM Deep-cycle

The Sun Xtender PVX-2580L is a valve-regulated lead-acid (VRLA) AGM deep-cycle solar battery designed for off-grid and grid-tied solar and wind energy storage systems, large-scale telecommunications and SCADA infrastructure, microgrid applications, island power systems, and commercial backup power installations.

A division of Concorde Battery Corp. — an industry pioneer in VRLA-AGM battery design since 1987 — Sun Xtender engineered the PVX-2580L on the large-format Group 8D platform with pure lead calcium grids and plates thicker than industry standard, delivering the absolute highest capacity of any single unit in the Sun Xtender lineup.

At 258Ah at the 24-hour rate and 300Ah at the 100-hour rate, the PVX-2580L is the definitive choice for commercial and remote power projects requiring maximum energy storage in a single sealed AGM unit.

Key Features:

• Flagship Group 8D Capacity — Delivers 258Ah at the 24-hour rate and 300Ah at the 100-hour rate — the highest capacity of any battery in the Sun Xtender lineup — in a single sealed Group 8D unit purpose-built for commercial, industrial, and large-scale off-grid energy storage systems
• "L" Blade Solid Copper Terminals — Heavy-duty solid copper flat blade terminal design shared only with the PVX-2120L in the Sun Xtender lineup; engineered for the high-current demands of large-format commercial battery bank applications and supplied with silicon bronze bolts, washers, and nuts for maximum conductivity and long-term connection reliability
• PolyGuard® Microporous Polyethylene Separators — Proprietary dual-layer insulation protection shields positive plates against shorting, shock, and vibration; a Sun Xtender exclusive feature not offered by any other manufacturer in the industry
• Pure Lead Calcium Grid Construction — Plates are thicker than industry standard for longer cycle life, increased reliability, and greater power output; low impedance AGM design allows excellent charge acceptance with no current limit required when using controlled voltage charging
• Non-Spillable VRLA-AGM Design — Valve-regulated, maintenance-free construction means no water replenishment ever; non-spillable design allows the battery to be used upright, on its end, or on its side without risk of electrolyte leakage
• High-Impact Copolymer Polypropylene Enclosure — Battery cover and container uniquely molded with reinforced copolymer polypropylene featuring thick end walls to prevent bulging under pressure; built to withstand the demands of rugged commercial, industrial, and large-scale off-grid environments
• Hazmat Exempt Shipping — All Sun Xtender batteries ship Hazmat Exempt, simplifying logistics for distributors, dealers, and end users across all shipping channels

The PVX-2580L delivers 258Ah of nominal capacity at the 24-hour rate and scales up to 300Ah at the 100-hour rate — the highest capacity ratings in the entire Sun Xtender range, representing a 22% increase over the Group 4D PVX-2120L at the 24-hour rate within the wider Group 8D footprint. At the 1-hour rate the battery delivers 165Ah, confirming its ability to supply very high current for shorter duration loads in large inverter, UPS, and commercial backup power systems. The low impedance AGM construction ensures excellent charge acceptance across the full range of charge rates with no current limit required when using a properly regulated charge source — a critical advantage in large commercial solar and wind systems where charge current varies significantly throughout the day.

Sun Xtender's proprietary PolyGuard® separator system provides a level of plate protection not available from competing AGM battery manufacturers, directly contributing to the PVX-2580L's long cycle life and resistance to vibration and shock loads common in telecommunications towers, remote SCADA installations, railroad communications, and mobile commercial applications. The "L" Blade solid copper terminal design is shared only with the PVX-2120L across the entire Sun Xtender product line — a deliberate engineering choice for the high-current connection demands of Group 4D and Group 8D large-format battery bank wiring. All Sun Xtender batteries ship Hazmat Exempt, eliminating the regulatory complexity and additional freight costs associated with non-exempt lead-acid battery shipments.
