PowerWarehouse 2XRBC55SLA559 cartridge pack

This two-pack supplies 12V lead-acid cartridges numbered 55 for the APC SUA2200I UPS. Each unit is built to match the original equipment specification so the UPS recognises the batteries immediately. The pack is intended for administrators who need a direct swap without reconfiguring the power-protection unit. Installation follows the standard front-panel replacement procedure.

Sustained discharge and recharge behaviour

Under continuous load the matched pair shares current evenly, keeping voltage stable for the rated backup window. The sealed construction prevents electrolyte loss during repeated deep-discharge cycles. Recharge acceptance remains consistent after multiple outages, so the UPS returns to full capacity within its normal charging window. Buyers needing longer runtime than the SUA2200I chassis allows should consider a higher-capacity UPS model.

Questions about this item

How much heat does the 12 V lead-acid cartridge produce during continuous UPS operation?

The sealed 12 V lead-acid cells generate only modest warmth under normal float charging; the APC SUA2200I chassis handles the thermal load without extra cooling.

What existing hardware must I already own for this 2-pack to function?

You need an APC SUA2200I uninterruptible power supply; the two cartridges slide directly into its internal battery bay.
