APC SUA1000 UPS Replacement Batteries - Set of 2 - Direct Fit

Our review of the APC SUA1000 UPS Replacement Batteries - Set of 2 finds them to be a straightforward, practical choice for anyone needing a reliable one-for-one swap for aging SLA cells. These replacement batteries are clearly aimed at users who want a cost-effective, guaranteed compatible option for their APC SUA1000 without modifying wiring or hardware. The single biggest reason to buy is compatibility: the pack is supplied factory fresh and guaranteed to fit models that use LW-6FM12S, LHR12-12, HR1251W, GPS12-12F2 or BP12-12 batteries, removing the guesswork from a UPS battery replacement.

Key Features

• Guaranteed compatibility: Supplied specifically as a replacement for LW-6FM12S and related models so customers can swap batteries without changing cables or connectors.
• Factory fresh cells: Each battery is brand new and sealed lead acid, which ensures full capacity out of the box and a predictable service life.
• Pair packaging: The item comes as a set of 2, so both UPS batteries can be replaced at once for balanced performance and easier maintenance.
• Manufacturer part number: Uses the SP12-12HR designation for 12 Volt, 12 AmpH batteries, matching expected electrical specifications for APC SUA1000 models.
• One year warranty: Includes a minimum one year warranty, providing basic protection against premature failure.

Who It's For

This replacement pack is best for home office users, small businesses, and IT technicians who maintain APC SUA1000 UPS units and want a direct-fit, no-fuss replacement. It suits anyone who prefers buying two matched sealed lead acid batteries at once to restore balanced runtime and maintain UPS reliability.

It is less suitable for someone seeking extended runtime upgrades, non-standard battery chemistries, or plug-and-play connector changes; buyers who need custom capacity or different voltages should look for specialist battery options or professional service.
