Compatible UPS battery cartridge

This two-pack supplies 12 V lead-acid cartridges built for the APC SU3000RMX93 uninterruptible power supply. Each unit matches the original RBC11 specification so the UPS recognises the replacement without configuration changes. The pack is intended for administrators who need to restore runtime on a single rack-mount unit.

Thermal and power behaviour

The sealed lead-acid chemistry runs passively with no fan, so operation adds no audible noise to the rack. Normal float charging draws only the low current the UPS charger provides, and the cells generate minimal heat during standby or discharge cycles. Buyers needing extended runtime beyond one cartridge pair will require additional UPS modules.

Questions about this item

How do I install the Cartridge #11 battery pack into my APC SU3000RMX93 UPS and what step is often missed?

Slide the cartridge into the UPS battery compartment until it locks firmly; the step often missed is reconnecting the internal battery connector before closing the door.

What maintenance will the 12V lead-acid cells in this 2-pack need and when should I plan a replacement?

These sealed cells require no watering; plan replacement after 3 to 5 years or when the UPS reports a battery fault.
