Compatible UPS Models

This 12 V DC sealed lead-acid battery replaces the APCRBC114-SLA114 unit in APC Back-UPS NS Network 40, BN4001 and BE450G models. It restores runtime for desktop workstations, home-office networking gear and small server closets that rely on those specific UPS units. The direct-fit design matches the original form factor so no wiring changes are needed.

Installation Notes

The battery arrives pre-charged and ready to install; simply open the UPS battery door, disconnect the old pack and connect the new one using the existing terminals. Polarity is keyed to prevent reverse connection, but verify the red and black leads match before seating the pack. A common issue is forgetting to recycle the spent battery — local regulations usually require drop-off at a hazardous-waste point.

Pre-Order Checks

Confirm the UPS model number on the rear label matches BN4001, BE450G or Back-UPS NS Network 40 before ordering. Ensure the replacement slot accepts the standard APCRBC114-SLA114 footprint, as some revised chassis use a different cartridge. Buyers needing extended runtime beyond the original capacity or a lithium chemistry alternative should look elsewhere.

Questions about this item

How can I confirm the 12 V DC sealed lead-acid battery is working correctly after installation in my UPS?

After fitting the replacement unit, power on the UPS and verify the front-panel status shows normal operation with no battery-fault indicator; then run a self-test from the UPS control panel or management software to confirm the 12 V DC pack holds voltage under load.

What items are included with the APCRBC114-SLA114 battery and what must I purchase separately?

The package contains the sealed 12 V DC lead-acid battery cartridge only; mounting hardware, connection cables and any UPS firmware updates are not included and must be sourced separately if required.

Which BTI battery version should I select for a UPS labelled Back-UPS NS Network 40, BN4001 or BE450G?

The APCRBC114-SLA114 is listed as compatible with Back-UPS NS Network 40, BN4001 and BE450G models; match the exact UPS model number on your unit to one of those three designations before ordering.
