  • Maintenance-free lead-acid design needs no water top-ups
  • Direct replacement for APC SUA2200R2ICH RBC43 cartridge
  • New sealed unit installs without special tools

PowerWarehouse LEADACIDSLA43-25 UPS battery

This 12V 5Ah sealed lead-acid unit replaces the APC RBC43 cartridge number 43 in the SUA2200R2ICH uninterruptible power supply. It arrives new and maintenance-free so installation is a direct swap without electrolyte handling. Buyers who need a different voltage or capacity will need another model.

Interface and runtime limits

The battery connects through the UPS's proprietary cartridge interface which fixes both voltage and communication protocol. Runtime scales with the 5Ah rating and the 2200VA load rating of the host unit so heavier loads reduce available minutes. Systems requiring hot-swap modules or extended runtime packs cannot use this cartridge.

Questions about this item

Should I pick the LEADACIDSLA43-25 or the RBC43 cartridge for my APC SUA2200R2ICH?

They are the same 12 V 5 Ah battery; LEADACIDSLA43-25 is the PowerWarehouse part number and RBC43 is the APC cartridge reference.

What does the 5 Ah rating mean when the battery is installed in the UPS?

It indicates the capacity to deliver 5 amps for one hour at 12 V, determining how long the SUA2200R2ICH can support its load during an outage.
