APC SU3000RMUS compatible replacement

This 12 V 22 Ah sealed lead-acid battery replaces the APC RBC12 cartridge number 12 in the SU3000RMUS uninterruptible power supply. It is built for server rooms and network closets that need a drop-in power source when the original cells reach end of life. The maintenance-free design means no electrolyte checks are required after installation.

Cartridge format simplifies swap-out

The battery ships pre-assembled in the RBC12 cartridge so technicians can exchange the entire pack without rewiring individual cells. This reduces downtime during scheduled maintenance and eliminates the risk of incorrect terminal connections. No additional mounting hardware or configuration software is supplied with the unit.

Questions about this item

When will the LEADACIDSLA12-22 battery need replacement?

The sealed lead-acid design is maintenance-free, so no water topping or servicing is required; plan to swap the cartridge after 3–5 years of normal UPS duty.

What limits runtime during a long outage on the SU3000RMUS?

The 12 V 22 Ah capacity sets the energy reserve; once the stored charge is depleted the UPS shuts down, so runtime is bounded by that amp-hour rating.
