APC RBC1 compatible kit

This replacement battery kit is designed for APC uninterruptible power supply units that require the RBC1 form factor. It contains two 6 V 4.5 Ah sealed lead-acid cells ready for immediate installation.

Capacity and headroom

The 4.5 Ah rating supports typical UPS loads for the rated runtime specified by the original equipment manufacturer. Runtime decreases when the connected load exceeds the UPS unit's rated capacity or as the batteries age beyond their service life.

Questions about this item

Will the 4.5Ah batteries fit the same tray as my old APC RBC1 kit?

Yes, this kit contains two 6V 4.5Ah units built to match the original RBC1 form factor so they slide into the existing battery compartment without modification.

How can I confirm the 4.5Ah cells are delivering full runtime after I install them?

Run a self-test from the UPS front panel or management software; a passed test and the expected runtime shown on the display mean the new 4.5Ah batteries are operating correctly.
