The Sun Xtender PVX-490T is a premium valve-regulated lead acid AGM deep cycle battery engineered for off-grid and grid-tied solar and wind energy storage systems as well as backup power for essential appliances and machines, delivering exceptional cycle life, superior charge acceptance, and non-spillable construction in a compact and lightweight Group 22NF form factor.

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 on every charge cycle.
• Compact Group 22NF Form Factor at Just 36 lbs — Versatile Installation Flexibility: The lightweight and compact design makes the PVX-490T ideal for space-constrained installations while still delivering 49Ah of reliable deep cycle capacity for solar, backup, and UPS applications.

The Sun Xtender PVX-490T 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-490T is a direct result of that deep industry expertise and continuous refinement.

Designed for off-grid, grid-tied, and backup power applications including cash registers, computers, and telephony systems, the PVX-490T delivers 49Ah of nominal capacity at the 24-hour rate and up to 54Ah at the 100-hour rate. Its compact Group 22NF footprint and 36 lb maximum weight make it one of the most versatile and installer-friendly batteries in the Sun Xtender lineup, fitting easily into tight spaces where larger Group 24 or Group 31 batteries cannot.

Shipping Hazmat Exempt, the PVX-490T is ready to deploy with standard M8 threaded insert terminals, an optional factory-installed SAE automotive post, and silicon bronze bolts, nuts, and washers included — everything needed for a clean, reliable installation right out of the box.
