Compatible replacement for APC SUA3000

This two-pack supplies 12 V 55 Ah lead-acid cartridges built to fit the APC SUA3000 uninterruptible power supply. Each unit meets the original equipment specification so the UPS can resume full runtime after a battery change. Installation follows the standard cartridge swap procedure without extra wiring.

Sustained discharge performance

Under continuous load the cells deliver steady voltage through the rated 55 Ah capacity, supporting the SUA3000 through extended outages rather than only brief spikes. Internal resistance remains stable across repeated cycles, so runtime does not degrade sharply after the first few events. The 100 % compatibility guarantee backs reliable operation over the service life.

Questions about this item

How much heat does the 12V 55 Ah cartridge generate when the SUA3000 runs continuously?

The sealed lead-acid cells produce minimal heat during normal float charging; the SUA3000’s internal fan handles dissipation without extra cooling.

What must I already own to install this 2-pack in my SUA3000?

You need a working APC SUA3000 UPS with its original battery tray and connectors; the cartridges slide straight into that chassis.
