Compatible replacement for Smart-UPS C 450

This battery kit is built for the APC Smart-UPS C 450 rack-mount 1U unit. It contains two sealed lead-acid cells pre-wired for direct installation. The kit suits IT managers and small-business owners who need a drop-in power refresh without rewiring.

RBC18-compatible 6 V 9 Ah cell configuration

The decisive specification is the dual 6 V 9 Ah high-rate discharge battery arrangement that matches the APC RBC18 layout. This exact voltage and capacity pairing ensures the UPS recognises the pack and reports runtime correctly.

Two-cell pack restores original 450 VA runtime

With both cells fresh, the UPS delivers its factory-rated backup time for typical network gear. Runtime scales down if the load exceeds the unit's 450 VA rating, so the pack is not suited for larger arrays or extended outage scenarios.
