Compatible Replacement Battery Kit for Smart-UPS

This replacement battery kit fits the Smart-UPS 750 Rack Mount LCD (SMT750RM2U) and the APC RBC 123. It contains two 12V9A sealed lead-acid batteries rated for high-rate discharge. The kit is designed for server and network equipment that rely on this UPS model for backup power.

Check Your Existing UPS Before Ordering

Verify that your unit is the Smart-UPS 750 Rack Mount LCD with model number SMT750RM2U. Confirm the UPS currently uses an RBC 123 battery cartridge so the two 12V9A blocks will match the original wiring harness. Ensure the battery compartment accepts two blocks of this capacity and voltage.

Factory-Fresh Build with Reusable Harness

The two batteries arrive factory fresh and are built for performance and reliability in demanding discharge applications. You keep the existing wiring harness, reducing electronic waste and simplifying installation. Comprehensive replacement instructions are included for a straightforward swap.

Questions about this item

Does the kit include the wiring harness or do I reuse the one from my SMT750RM2U?

The kit supplies two 12V9A batteries only; you reuse the existing wiring harness from your UPS.

Why are there two 12V9A batteries instead of a single larger cell?

The SMT750RM2U requires a matched pair of 12V9A units to deliver the correct voltage and runtime.

How long will the 750 VA UPS run on this replacement set under typical load?

Runtime depends on the connected load; the pair restores the original capacity designed for the 750 VA unit.
