Product Overview
The APC APCRBC124 #124 replacement battery cartridge is a genuine APC UPS replacement battery that restores runtime on supported APC Back-UPS and Smart-UPS Line Interactive systems. This 24V 9Ah lead-acid cartridge is tested and certified by Schneider Electric (APC) to return your unit to its original backup performance after the factory batteries have aged. Swapping in a fresh APCRBC124 cartridge maintains reliable battery backup for the connected equipment your UPS protects. It is the direct way to refresh capacity without replacing the entire UPS.
Product Description

The APCRBC124 is a pre-assembled 9Ah, 24Vdc replaceable battery cartridge for supported APC Back-UPS and Smart-UPS Line Interactive models. APC packages its replacement batteries as cartridges so the full pack is swapped as one certified assembly, keeping wiring and connectors consistent with the original equipment. Because battery capacity declines over the service life of any UPS, fitting a fresh cartridge is the most effective way to maintain rated runtime. On supported models the battery is user-replaceable, and hot-swap capability depends on the specific UPS, so confirm against your unit before servicing. APC uses two naming conventions for its cartridges: older parts carry the RBC prefix while newer parts use the APCRBC prefix, and this item is the APCRBC124. The cartridge ships brand new from a strictly managed warehouse, carries a 2-year warranty with UPS safety certifications, and supports APC-authorized recycling for responsible disposal of the spent battery.
Key Features
- Genuine APC cartridge — As a factory APC RBC, the APCRBC124 is tested and certified by Schneider Electric to restore your UPS to original specifications.
- 24V 9Ah lead-acid battery — The sealed lead-acid chemistry delivers the rated voltage and capacity your Back-UPS or Smart-UPS Line Interactive was designed around.
- Broad model coverage — The 9Ah 24Vdc replaceable battery serves supported APC Back-UPS and Smart-UPS Line Interactive systems.
- Fully assembled and ready for use — The cartridge ships pre-built so installation is a direct swap rather than building a battery pack.
