APC PowerStack 450 Battery Kit

This replacement battery kit is designed for the APC PowerStack 450 rack-mount 1U uninterruptible power supply. It contains two 6V9A batteries configured as a compatible cartridge for the APC RBC18. The kit suits administrators maintaining existing PowerStack 450 units in server racks.

Compatible Cartridge Limits

The cartridge fits only the PowerStack 450 model and the APC RBC18 form factor. It will not work with other UPS models, larger rack units, or external battery packs that use different connectors or voltages. Buyers needing higher runtime or a different form factor must select a kit matched to their specific UPS.

Questions about this item

Should I choose the single kit or a multi-pack for my PS450?

The kit contains two 6V9A batteries pre-assembled to match the PS450 cartridge, so one kit restores full runtime.

What does the 450 rating mean for actual backup time?

The 450 VA rating reflects the UPS output capacity; with fresh batteries the unit will support its rated load for the manufacturer-specified runtime.
