The Sun Xtender PVX-690T is a premium valve-regulated lead acid AGM deep cycle battery engineered specifically for off-grid and grid-tied solar and wind energy storage systems, delivering exceptional cycle life, superior charge acceptance, and non-spillable construction for reliable renewable energy storage in the most demanding applications.

Key Features:

• Pure Lead Calcium Grid Construction with Thicker-Than-Industry-Standard Plates: Engineered with pure lead calcium grids and plates thicker than the industry standard, delivering longer cycle life, increased reliability, and superior power output compared to conventional AGM batteries.
• Proprietary PolyGuard Microporous Polyethylene Separators — Exclusive Dual Layer Protection: Sun Xtender's patented PolyGuard separators shield positive plates against shorting, shock, and vibration — a dual layer insulation protection feature not offered by any other manufacturer in the industry.
• Non-Spillable VRLA-AGM Construction — No Water Monitoring Required: The sealed valve-regulated AGM design eliminates the need to monitor and replenish water levels, delivering truly maintenance-free operation across the full service life of the battery.
• Low Impedance AGM Design for Excellent Charge Acceptance: The low impedance construction allows for superior charge acceptance with no current limit required during controlled voltage charging, maximizing solar energy harvest efficiency.
• High Impact Reinforced Copolymer Polypropylene Case with Thick End Walls: The rugged case material and thick end wall design prevent bulging under pressure, while corrosion-resistant copper alloy M8 threaded insert terminals with silicon bronze bolts and washers ensure long-term connection integrity.

The Sun Xtender PVX-690T represents over three decades of innovation in renewable energy battery design. Since 1987, Sun Xtender — a division of Concorde Battery Corp — has been engineering VRLA-AGM batteries specifically for the demands of solar and wind energy storage, and the PVX-690T is a direct result of that deep industry expertise and continuous refinement.

Designed for off-grid, grid-tied, and uninterruptible power applications, the PVX-690T delivers 69Ah of nominal capacity at the 24-hour rate and up to 78Ah at the 100-hour rate — providing the deep, sustained discharge performance that renewable energy systems demand. Its compact Group 24 form factor and two rope lifting handles make the PVX-690T an ideal choice for installations where space efficiency and ease of handling are as important as performance.

Shipping Hazmat Exempt, the PVX-690T is one of the most installer-friendly AGM deep cycle batteries available for residential and commercial solar applications. With standard M8 threaded insert terminals, an optional factory-installed SAE automotive post, and a Group 24 industry reference classification, the PVX-690T integrates cleanly into virtually any solar storage system design.
