Compatible Replacement for APC SUA3000XL

This sealed lead-acid battery replaces the APC RBC55 cartridge used in the SUA3000XL uninterruptible power supply. It is designed for IT managers maintaining backup power for servers and network equipment. The maintenance-free construction means no fluid checks are required during its service life.

Steady Output During Extended Discharge

Under sustained load the chemistry delivers a stable voltage curve rather than a brief peak, keeping connected gear running smoothly throughout a prolonged outage. It is not suited for applications needing lithium energy density or rapid recharge cycles.
