PowerWarehouse LEADACIDSLA12-23 UPS Replacement Battery

SKU CH-W3XA-14FWK

A 12 V 23 Ah sealed lead-acid cartridge replaces the APC RBC12 in compatible UPS units

  • Maintenance-free design eliminates electrolyte checks
  • 12 V 23 Ah capacity powers critical UPS loads
  • Direct replacement for APC RBC12 cartridge #12
  • Sealed lead-acid construction prevents leaks and spills

Direct RBC12 replacement

This sealed lead-acid battery matches the APC RBC12 cartridge specification. It delivers a 12 volt output in a maintenance-free design. Install it in compatible UPS units to restore backup runtime without wiring changes. The PowerWarehouse LEADACIDSLA12-23 arrives ready for immediate service.

Upgrade from depleted RBC12 cells

Swap this cartridge when the original RBC12 pack no longer holds charge or self-tests fail. The jump is worth it when runtime has dropped below useful levels and the UPS electronics remain sound. Buyers who need a higher capacity than the standard 23 Ah rating should verify chassis fit before ordering.
