APC PowerStack 250 Rack Mount 1U Replacement Battery

This factory-fresh compatible battery kit replaces the APC RBC18 cartridge in PowerStack 250 1U rack-mount UPS units. It contains two 6V9A batteries designed to restore runtime for critical server and network equipment.

Upgrades expired or depleted RBC18 cartridges

The jump is worth it when the UPS reports a battery fault or runtime falls below operational needs. Buyers needing a different voltage, capacity, or form factor should verify their specific UPS model before ordering.

Questions about this item

Will the PS250I battery kit fit in a standard 1U rack space?

Yes, the PowerStack 250 is designed as a 1U rack-mount unit, so it occupies a single rack unit of vertical space.

How do I install the two 6V9A batteries inside the cartridge, and what step is often missed?

Slide the cartridge into the UPS chassis, connect the red and black leads to the matching terminals, then secure the front cover; the step most often missed is fully seating the connector until it clicks.
