Compatible Battery Kit for Smart-UPS 1500

This replacement kit fits the APC Smart-UPS 1500 Rack Mount LCD model SMT1500RM2U. It contains four 12V9A sealed lead-acid batteries that match the APC RBC133 specification. The kit is designed for users who need to restore runtime to an existing UPS without replacing the whole unit.

Reuses existing wiring harness

The batteries arrive ready to install into the current battery tray using the harness already inside the UPS. No new cabling or connectors are required, which keeps the swap straightforward and avoids extra parts. Comprehensive installation instructions are included to guide the process step by step.

High-rate discharge cells for reliable runtime

The four 12V9A batteries are built for high-rate and long-duration discharge cycles typical of rack-mount UPS applications. Factory-fresh cells deliver consistent performance during outages while maintaining stable voltage under load. The sealed design eliminates routine maintenance and reduces the risk of leakage in the rack.

Questions about this item

How long will the four 12 V 9 Ah cells sustain the UPS under full load before the low-battery shutdown triggers?

Runtime depends on the connected load and the UPS firmware; the kit supplies four 12 V 9 Ah SLA batteries that match the original RBC133 capacity.

What temperature rise or fan noise should I expect when the battery pack is powering the rack-mount unit continuously?

The sealed lead-acid cells generate minimal heat and no audible noise; the UPS chassis fans handle any thermal load exactly as with the factory pack.

Do I need to supply any extra cables, connectors or mounting hardware to install this kit in an SMT1500RM2U?

No; the kit reuses the existing wiring harness and fits the original battery tray, so only the four replacement cells are required.
