Your UPS has been running on a tired battery and the runtime warning keeps flashing. You don't need a guess — you need the exact cartridge that drops in, clicks shut, and keeps your router, POS terminal, or server alive through the next brownout.
The APC RBC2 is a genuine 12V, 7Ah valve-regulated lead-acid battery cartridge, tested and certified for 100% compatibility with the specific APC UPS models listed below. It comes fully assembled: connectors, installation guide, and a recycling guide are in the box. No soldering, no guesswork. Swap it in, close the panel, done.
Expected service life sits at three to five years under normal conditions (operating range 0–40 °C). Backed by a 2-year APC warranty so you're covered if it doesn't hold charge.
