APC Replacement Battery Cartridge #159

The APC APCRBC159 is a battery cartridge that restores the original runtime and reliability of compatible APC Smart-UPS units. By replacing an aging battery with this factory-spec module, you keep servers, networking gear, and other sensitive electronics powered during outages and voltage fluctuations without having to purchase a new UPS.

The cartridge arrives preassembled inside an enclosed case. Lead acid cells, wiring, and quick-release connectors are already in place, so installation involves sliding the module into the UPS and attaching the included plugs—no soldering or complex assembly required. The design also keeps the battery secure during handling and helps prevent accidental contact with internal components.

With dimensions of 13.5 x 8.5 x 3.27 inches and a weight of about 26 pounds, the APCRBC159 fits neatly into models such as the SMT1500RM2U and other systems listed in APC documentation. It installs inside the UPS chassis and is not intended for separate rack mounting.

The battery operates between 32 and 104 degrees Fahrenheit, tolerating typical data center and office environments. APC backs the cartridge with a two year repair or replacement warranty, providing confidence that your power protection plan will remain dependable.

This replacement is well suited for IT managers refreshing equipment in server closets, small businesses that need continuous point-of-sale uptime, and home lab enthusiasts who want to avoid unexpected shutdowns. Swapping the cartridge extends the useful life of the UPS, saves budget, and reduces electronic waste.
