Direct replacement for Battery Cartridge 133

The PowerWarehouse APCRBC133-PW is a sealed lead-acid unit built to replace APC Battery Cartridge #133 in compatible Smart-UPS models. It fits the listed SMC2000I and SMT1500 series rack-mount and tower units without modification. The maintenance-free design eliminates the need for electrolyte checks. It arrives new and ready for installation in critical power infrastructure.

Steady output during extended runtime events

The sealed lead-acid chemistry delivers consistent voltage across the full discharge curve rather than a brief peak. Internal resistance remains stable as the cells deplete, so connected equipment sees clean power until the UPS initiates its low-battery shutdown. The 26.8 lb mass reflects the plate area needed for sustained current without excessive voltage sag. No active cooling is required during prolonged outages.

Leak-proof construction simplifies rack mounting

The ABS casing is sealed to prevent electrolyte leakage in any orientation, allowing horizontal or vertical installation in 2U rail kits. Dimensions of 13.5" L x 8.50" W x 3.25" H match the original cartridge footprint so existing battery trays and front-panel latches engage correctly. Terminals are positioned for the OEM wiring harness, reducing cable strain. The 18 month warranty period covers manufacturing defects. Buyers needing lithium-ion cycle life or hot-swap modularity should look elsewhere.

Questions about this item

How much heat does the 26.8 lb sealed lead-acid cartridge produce during continuous UPS operation?

The maintenance-free sealed lead-acid design runs without active cooling, so it adds minimal heat inside the UPS chassis during all-day use.

Which UPS models must I already own for the APCRBC133-PW cartridge to fit and connect?

It replaces Battery Cartridge #133 in APC units including SMC2000I-2U, SMC2000I-2URS, SMT1500R2-NMC, SMT1500R2I-6W, SMT1500R2I-AR, SMT1500R2X122, SMT1500R2X180, SMT1500RM2U, SMT1500RM2UNC, SMT1500RM2UTW, SMT1500RMI2U, SMT1500RMI2UNC and SMT1500RMUS.

Will the 13.5 x 8.5 x 3.25 inch cartridge work in an older Smart-UPS 1500 RM 2U that still uses the original RBC133?

Yes, it directly replaces the RBC133 cartridge used in those legacy 2U rack-mount Smart-UPS 1500 models.
