PowerWarehouse 2XRBC2SLA283 UPS battery pack

This pack contains two 12 V lead‑acid cartridges built to replace APC RBC2 modules. It is intended for administrators maintaining compatible APC uninterruptible power supplies who need a direct drop‑in swap.

Sealed lead‑acid construction for rack‑mount UPS

Each cartridge arrives factory sealed and ready to install without tools or wiring changes. The matched pair restores runtime in a single service window, and the sealed design prevents leakage during routine rack handling. Not suited for UPS models that require a different cartridge form factor or voltage.
