APC SURTA1500RMXL2U Battery Kit

This kit supplies four 12V7A sealed lead-acid batteries designed as a compatible replacement for the APC Smart-UPS RT 1500 rack-mount unit. It targets IT administrators and facility managers who need to restore backup power to a SURTA1500RMXL2U system. The package matches the APC RBC 57 cartridge specification.

Sustained Discharge Performance

The cells are rated for high-rate discharge, meaning they maintain voltage stability during the extended runtime demands of a loaded 1500 VA UPS. Unlike general-purpose SLA packs, these batteries are built to support continuous inverter draw without premature voltage sag. Factory-fresh stock ensures each cell starts at full capacity.

Physical and Compatibility Limits

Installation is constrained to the existing battery compartment of the SURTA1500RMXL2U chassis; the kit adds 24 units of weight to the rack. No additional wiring adapters or firmware updates are required beyond the included instructions. The kit does not expand the UPS runtime beyond the original design envelope.

Questions about this item

How much heat will the four 12V7A batteries generate during continuous operation?

The sealed lead-acid cells produce only minimal warmth under normal float charge; no active cooling is required inside the rack enclosure.

What must I already have installed to use this replacement kit?

You need an APC Smart-UPS RT 1500 rack-mount unit (model SURTA1500RMXL2U) with its original battery tray and connectors in place.

Will this kit fit the original RBC57 cartridge slot in my older Smart-UPS RT 1500?

Yes, the four 12V7A batteries are dimensionally identical to the factory RBC57 pack and slide straight into the existing chassis.
