PowerWarehouse LEADACIDSLA133-01 UPS Battery

This PowerWarehouse LEADACIDSLA133-01 is a new replacement battery cartridge designed for the APC SMT1500RM2U uninterruptible power supply. It uses maintenance-free lead-acid chemistry and arrives ready to install without additional preparation. The cartridge restores backup runtime for connected servers and network equipment.

Capacity and headroom for APC SMT1500RM2U

The cartridge replaces the original RBC133 assembly and supports the 1500 VA rating of the host UPS. It handles typical rack-mounted server loads during short utility interruptions. Runtime decreases as the connected load approaches the unit's maximum capacity. Buyers needing extended runtime beyond a single cartridge should verify compatibility with external battery packs.

Questions about this item

Will the RBC133 cartridge fit alongside the existing batteries in my APC SMT1500RM2U?

The RBC133 cartridge is designed as a direct replacement for the APC SMT1500RM2U and contains the correct number of maintenance-free lead-acid cells to match the original configuration.

How can I verify the new LEADACIDSLA133-01 battery is working after installation?

After installing the cartridge, run a self-test from the UPS front panel or management software; a passed test and normal runtime during a simulated power loss confirm the replacement is functioning correctly.
