Compatible replacement for APC SUA3000XLT

This two-pack supplies 12V 55 Ah lead-acid cartridges built to fit the APC SUA3000XLT uninterruptible power supply. Each unit is guaranteed 100% compatible with the original equipment so the UPS recognises the battery without configuration changes. The pack restores full runtime for servers and network gear that depend on continuous power. Installation follows the standard cartridge swap procedure used by the original manufacturer.

Thermals noise and power draw in normal use

Sealed lead-acid chemistry runs silently because there are no moving parts or cooling fans. Heat output stays low during float charge and typical discharge cycles, keeping rack temperatures stable. The batteries accept charge at the rate managed by the UPS controller, drawing only the current required to maintain full capacity. No additional power infrastructure is needed beyond the existing SUA3000XLT chassis.

Questions about this item

How do I install the two 12 V 55 Ah cartridges into my APC SUA3000XLT without missing a step?

Power down the UPS, open the battery door, unplug the old cartridge connectors, slide in both new 12 V 55 Ah cartridges, reconnect the same plugs firmly, close the door, then run the self-test to confirm the UPS recognises the new pair.

What replacement cycle should I expect for the 12 V 55 Ah cartridges in an APC SUA3000XLT?

The sealed lead-acid cartridges typically last three to five years; when the UPS runtime drops noticeably or the replace-battery indicator lights, swap both cartridges together to keep the 3000 VA unit at full backup capacity.
