Direct replacement for APC SUA1000RM2U

This two-pack of 12 V lead-acid cartridges is built to match the original equipment in the APC SUA1000RM2U uninterruptible power supply. Each unit carries the model designation 2XRBC23SLA234 and installs without modification. The set suits administrators who need a like-for-like swap to restore runtime on an existing rack-mount UPS.

Passive thermal behaviour and low self-discharge

The sealed lead-acid chemistry operates without fans, so the UPS emits no additional noise during normal float charge or discharge cycles. Internal resistance remains stable across typical office temperatures, keeping power draw predictable during routine conditioning. No active cooling is required, and the batteries maintain readiness over extended standby periods.

Questions about this item

How do I install the 12 V lead-acid cartridges into my SUA1000RM2U UPS?

Power off and unplug the UPS, open the front battery door, slide out the old cartridge, insert the new 2XRBC23SLA234 pack in the same orientation, close the door and restart the UPS so it recognises the fresh cells.

When will the 2-pack need replacement and what signs should I watch for?

Typical life is 3–5 years; plan a swap when runtime falls noticeably or the UPS signals a battery fault during its automatic self-test.
