SKU CH-FKAR-C3R18

12 V 9 Ah maintenance-free lead-acid cartridge replaces APC RBC12 in SU5000TXFMR units

  • Maintenance-free design reduces upkeep for APC SU5000TXFMR units
  • 12 V sealed lead-acid chemistry delivers reliable backup power
  • Direct RBC12 cartridge replacement simplifies installation
  • 9 Ah capacity supports extended runtime during outages

Direct APC SU5000TXFMR fit

The PowerWarehouse LEADACIDSLA12-09 is a maintenance-free lead-acid battery cartridge built to replace the APC RBC12 module inside the SU5000TXFMR uninterruptible power supply. It arrives new and ready to install without additional wiring or configuration.

Sustained discharge stability

The sealed lead-acid chemistry delivers consistent voltage through the full discharge cycle of a 5000 VA load rather than only during brief outages. Internal resistance remains low enough to support extended runtime without premature voltage sag. Buyers who need hot-swappable lithium modules or network-managed battery strings will not find those features here.
