Compatible Battery Kit for APC Smart-UPS 400

This replacement kit provides a factory-fresh power source for the APC Smart-UPS 400 SU400-Slim uninterruptible power supply. It contains four 6V 4.5Ah batteries configured as two APC RBC1 compatible cartridges. The kit weighs 12 units and is ready for immediate installation.

Lead-Acid Chemistry Limits Runtime and Cycle Life

The sealed lead-acid cells deliver reliable backup but lose capacity after repeated deep discharges. Users needing longer runtime per outage or a higher number of discharge cycles will find this chemistry restrictive. The kit matches the original 400 VA rating only and cannot extend the unit's rated output.
