Sun Xtender PVX-1380T 6V 138Ah Solar Battery - VRLA AGM Deep-cycle

The Sun Xtender PVX-1380T is a 6-volt valve-regulated lead-acid (VRLA) AGM deep-cycle solar battery designed for off-grid and grid-tied solar and wind energy storage systems, remote SCADA and telemetry installations, navigational aids, traffic and message boards, cathodic protection systems, and telecommunications infrastructure.

A division of Concorde Battery Corp. — an industry pioneer in VRLA-AGM battery design since 1987 — Sun Xtender engineered the PVX-1380T on the same compact Group 24 platform as the PVX-1030T, delivering 138Ah at the 24-hour rate — 34% more stored energy in an identical case footprint.

As the highest-capacity 6-volt model in the Sun Xtender Group 24 lineup, the PVX-1380T is the preferred choice when maximum amp-hour storage is required without increasing battery bank dimensions, making it an ideal drop-in capacity upgrade for existing 6-volt PVX-1030T installations.

Key Features:

• Highest-Capacity 6V Group 24 Model — Delivers 138Ah at the 24-hour rate in the same compact BCI Group 24 footprint as the PVX-1030T — 34% more stored energy, zero additional installation space, purpose-built for series-wired 12V and 24V battery banks requiring maximum capacity per unit
• 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

The PVX-1380T delivers 138Ah of nominal capacity at the 24-hour rate and scales up to 155Ah 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 84Ah, 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-1380T's long cycle life and resistance to the vibration and shock loads common in remote telemetry, traffic management, navigational aid, and mobile off-grid installations. Sharing the identical Group 24 case dimensions with the PVX-1030T, the PVX-1380T allows existing 6-volt battery banks to be upgraded to 138Ah capacity without any modification to battery compartments, trays, or cabling — the additional 35Ah of 24-hour capacity over the PVX-1030T comes entirely from the denser plate construction within the same outer envelope. All Sun Xtender batteries ship Hazmat Exempt, eliminating the regulatory complexity and additional freight costs associated with non-exempt lead-acid battery shipments.
