APC APCRBC143 #143 Replacement Battery Cartridge
Product Overview
The APC APCRBC143 #143 replacement battery cartridge is a genuine APC UPS replacement battery built to restore runtime on supported APC Smart-UPS systems. As a factory APC RBC, this 120V 5Ah lead-acid cartridge returns your unit to its original backup performance after the original batteries have aged or failed. It is tested and certified by Schneider Electric (APC) for compatibility, so you maintain reliable battery backup for the equipment your UPS protects. This APCRBC143 cartridge is the direct path to refreshing capacity without replacing the entire UPS.
Product Description
The APCRBC143 is a pre-assembled replacement battery cartridge for supported APC Smart-UPS models. It uses a sealed, leak-proof lead-acid battery rated at 120V and 5Ah, shipped brand new and ready to install. APC packages its replacement batteries as cartridges so the full battery pack is swapped as a single certified assembly, which keeps wiring and connections consistent with the original equipment. Replacing aged batteries is the most effective way to maintain rated runtime, since battery capacity declines over the service life of any UPS. On supported Smart-UPS models the battery is user-replaceable, and hot-swap capability depends on the specific UPS model, so confirm against your unit before servicing. Note that 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 APCRBC143. The cartridge supports APC-authorized recycling for responsible disposal of the spent battery.
