Compatible replacement cartridge

This twin-pack supplies two 12 V lead-acid cartridges built to match the APC NS2200RMI3U UPS. Each unit is verified for 100 % compatibility with the original equipment so installation is a direct swap. The batteries arrive new and ready for immediate deployment in server-room or rack-mount environments.

Capacity and runtime limits

The pair restores the UPS to its factory 2200 VA rating, giving enough reserve for graceful shutdown of attached loads during brief outages. Extended runtime beyond the standard discharge curve is not supported, so sites needing longer autonomy will require additional UPS units or external battery modules.

Questions about this item

Will the 2XRBC12SLA1231 cartridge fit my existing APC NS2200RMI3U unit without modification?

Yes, this 12 V cartridge is built to match the original APC NS2200RMI3U form factor and connector layout, so it slides into the same bay and plugs in directly.

How can I verify the 2XRBC12SLA1231 pack is delivering the rated 12 V output after installation?

After powering on the UPS, run a self-test from the front panel or management software; a successful test confirms the battery string is holding voltage and ready for runtime.
