Sun Xtender PVX-1040T 12V 104Ah Solar Battery - VRLA AGM Deep-cycle

The Sun Xtender PVX-1040T 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, uninterruptible power applications, and renewable energy installations.

A division of Concorde Battery Corp. An industry pioneer in VRLA-AGM battery design since 1987 — Sun Xtender engineered the PVX-1040T with pure lead calcium grids and plates thicker than industry standard, delivering longer cycle life, increased reliability, and higher power output than conventional AGM batteries.

The non-spillable AGM construction eliminates the requirement to monitor and replenish water levels entirely, while allowing installation in any orientation — upright, on its end, or on its side.

Key Features:

• 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
• 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
• Non-Spillable VRLA-AGM Design — Valve-regulated, maintenance-free construction eliminates the requirement to monitor and replenish water levels; non-spillable design allows installation in any orientation — upright, on its end, or on its side — without risk of electrolyte leakage
• M8 Copper Alloy Threaded Insert Terminals — Corrosion-resistant copper alloy M8 threaded insert terminals supplied complete with silicon bronze bolts, nuts, and washers required for installation; optional factory-installed SAE automotive post terminal available by adding "A" suffix to part number
• 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 off-grid and renewable energy environments
• Hazmat Exempt Shipping — All Sun Xtender batteries ship Hazmat Exempt, simplifying logistics for distributors, dealers, and end users across all shipping channels
• Dual Rope Lifting Handles — Integrated rope lifting handles on both ends of the battery facilitate safe handling and installation of the 63 lb unit without additional lifting equipment

The PVX-1040T delivers 104Ah of nominal capacity at the 24-hour rate and scales up to 118Ah at the 100-hour rate, making it well suited for the slow, sustained discharge cycles typical of off-grid solar storage applications. At the 1-hour rate the battery delivers 65Ah, confirming its ability to supply high current for shorter duration loads in inverter and backup power applications. 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 significant advantage in solar systems where charge current varies with available irradiance 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-1040T's long cycle life and resistance to the vibration and shock loads common in marine, RV, and mobile off-grid installations. As a Group 27 battery, the PVX-1040T occupies a form factor between the Group 24 PVX-840T and the Group 31 PVX-890T, offering 104Ah of 24-hour capacity in a standard Group 27 footprint compatible with common battery compartments and trays. All Sun Xtender batteries ship Hazmat Exempt, eliminating the regulatory complexity and additional freight costs associated with non-exempt lead-acid battery shipments.
