SKU CH-6KDR-RZ2WC

Maintenance-free 12 V 5 Ah lead-acid cartridge replaces APC RBC43 in SUA2200R2X180 UPS units

  • Direct replacement for APC SUA2200R2X180 UPS units
  • Maintenance-free lead-acid chemistry eliminates fluid checks
  • 12 V 5 Ah rating matches original cartridge specifications
  • PowerWarehouse LEADACIDSLA43-28 built as RBC43 #43 equivalent

Compatible with APC SUA2200R2X180 UPS

This 12 V 5 Ah sealed lead-acid battery replaces the APC RBC43 cartridge in the SUA2200R2X180 uninterruptible power supply. It is built for server rooms and network closets that need a direct drop-in cell to restore backup runtime. Maintenance-free chemistry means no electrolyte checks are required after installation.

Pre-wired cartridge fits original chassis

The unit arrives as a complete cartridge assembly matching the original form factor, so installers slide it into the UPS without rewiring or adapter brackets. Terminals align with the factory connector, reducing replacement time during scheduled maintenance windows. No additional cables or mounting hardware are included because the cartridge reuses the existing hardware.

Questions about this item

When will this 12V 5Ah SLA battery need replacing under normal UPS duty?

A sealed lead-acid cell in a UPS typically lasts three to five years before capacity drops below useful levels; plan on a swap in that window.

What limit appears first when the SUA2200R2X180 runs on this RBC43 cartridge during a long outage?

The 5Ah rating governs runtime; once the stored charge is depleted the UPS shuts down regardless of load.
