PowerWarehouse 2XRBC133SLA1331 Battery Pack

This two-pack replaces the original cartridge number 133 for the APC SMT1500RM2UTW uninterruptible power supply. It uses sealed lead-acid chemistry and is built to match the electrical profile of the factory module. The batteries arrive new and ready for immediate deployment in compatible rack-mount UPS units.

Simple Front-Access Swap

Installation requires opening the front panel, disconnecting the old cartridge, and sliding the new one into the same rails. The connector is keyed to prevent reverse polarity, so the fit is straightforward. The main risk is leaving the UPS unpowered during the swap, which drops the load if utility power fails at that moment. Buyers needing hot-swap capability without any downtime should verify their specific UPS model supports that feature before ordering.

Questions about this item

How do I verify the 2XRBC133SLA1331 batteries are working after installing them in my SMT1500RM2UTW?

The UPS will run a self-test on start-up and the front-panel status lights will show normal operation when the cartridge is seated correctly.

What comes in the 2-pack and do I need any extra cables or trays for the SMT1500RM2UTW?

The pack contains two complete cartridge #133 units that slide straight into the UPS; no additional cables or mounting hardware are required.
