PowerWarehouse 2XRBC133SLA1333 Replacement Pack

This two-pack of lead-acid cartridges is built for the APC SMT1500RMUS uninterruptible power supply. It restores the original runtime and load support that the UPS was designed to deliver. The batteries arrive new and are guaranteed 100% compatible with the specified unit. Install them to bring the backup system back to factory-spec readiness.

Capacity and headroom for the SMT1500RMUS

The pair supplies the energy reserve the 1500 VA unit expects, keeping connected servers or network gear running during an outage. Runtime scales with the attached load, so lighter configurations last longer while heavier draws deplete the reserve faster. Once the stored charge is exhausted, the UPS shuts down until mains power returns. Buyers needing extended runtime beyond the standard cartridge capacity will require a different solution.
