This listing is for a clean, fully functional CyberPower PR750LCD3C Smart App Sinewave Mini-Tower Uninterruptible Power Supply (UPS) rated for 750VA and 750W with a pure sine wave output ideal for sensitive electronics. The unit has been thoroughly bench-tested and officially passed its diagnostic self-test, confirming excellent internal component and circuitry health. The internal battery cartridge was replaced in August 2025, meaning these premium sealed lead-acid cells have under a year of standard wear and possess an estimated 2 to 4 years of remaining operational lifespan before requiring a future swap. Cosmetically, the heavy 26-pound hardware is in very clean condition, offering six battery-backed and surge-protected NEMA 5-15R outlets alongside a tilting multifunction LCD control panel for real-time electrical status monitoring. While a brand-new unit retails for $468.95 USD, this professionally verified, pre-owned system offers exceptional secondary market value for home servers, networking gear, or gaming setups.
