APC Back-UPS NS 1080 G Compatible Replacement Kit

This replacement battery kit is designed for the APC Back-UPS NS 1080 G uninterruptible power supply. It consists of two 12V9A batteries that match the APC RBC 123 specification. The unit ships factory fresh and ready for immediate installation by home-office users or small-business administrators who need to restore backup runtime.

Sealed lead-acid design runs without active cooling

The sealed lead-acid cells operate silently because no fan is required. Heat output stays low during normal float charging and typical discharge cycles. Each battery weighs 14 units, contributing to a stable, maintenance-free power reserve that fits the original UPS chassis.

Questions about this item

How do I install the two 12V9A batteries in the RBC 123 cartridge for my Back-UPS NS 1080 G?

Remove the front cover, disconnect the old cartridge, slide in the new RBC 123 kit with both 12V9A units pre-wired, then reconnect the plug and replace the cover.

When will the 12V9A batteries inside the RBC 123 cartridge need replacing again?

Expect three to five years of service; replace the cartridge when the UPS shows a battery warning or runtime drops noticeably.
