APC SUA3000RMXL3U UPS Replacement Batteries - Set of 8

Our review examines the replacement battery set for the APC SUA3000RMXL3U UPS and concludes this pack is a straightforward option for users who need a reliable, compatible battery swap. In this review the main reason to buy is compatibility: these factory fresh, sealed lead acid cells are supplied as an eight-pack specifically to replace the modules in that APC model, and they guarantee fit with existing cables and hardware. For anyone running a SUA3000RMXL3U and wanting to restore runtime quickly, this is a practical choice.

Key Features

• Guaranteed compatibility: Sold as a direct replacement set for UB1280-F2 (D5779) and other compatible part numbers so users can expect a correct fit with the SUA3000RMXL3U chassis.
• Factory fresh SLA chemistry: These are sealed lead acid batteries supplied new, which helps ensure predictable performance and safe, maintenance-free operation.
• Complete eight-pack: The item package quantity of 8 supplies a full replacement for UPS models that require multiple modules, avoiding piecemeal purchases and mismatched ages.
• Known part number: Uses the manufacturer part SP12-7.5HR (12 Volt 7.5 AmpH), a familiar spec for UPS technicians replacing these modules.
• One year warranty: The replacement SLA batteries include a minimum one year warranty, giving basic protection against early failures.

Who It's For

This replacement set is aimed at IT staff, small datacenter operators, and advanced home users who already own an APC SUA3000RMXL3U and need a like-for-like battery replacement to restore runtime and redundancy. It is particularly helpful where maintaining the original battery bank configuration matters and where users will reuse the UPS cables and mounting hardware.

Users who want plug-and-play solutions that include new wiring or nonstandard voltages, or who require extended manufacturer-backed service plans beyond a basic warranty, should consider professional service options instead. This product assumes reuse of the existing UPS connectors and trays.
