APC BE850G2 UPS Battery Backup & Surge Protector for Computer, Router, NAS

The APC Back-UPS BE850G2 is a compact 850VA/450W UPS battery backup and surge protector designed to protect home and office electronics during power outages, voltage fluctuations, and damaging electrical surges. This UPS features 9 total NEMA 5-15R outlets — 6 that provide both battery backup and surge protection, plus 3 that provide surge-only protection — giving you the flexibility to prioritize which devices stay powered and which are simply shielded from surges. Use the BE850G2 as a battery backup for a computer, monitor, Wi-Fi router, modem, networking equipment, gaming console, and other essential electronics. When utility power fails, it delivers up to 35 minutes of runtime at a 100W load, giving you time to stay connected, save your work, and safely shut down your equipment. A 354-joule surge energy rating, audible alarms, and an LED status display provide clear notification of UPS and utility power conditions, while a built-in Wiring Fault Indicator LED alerts you to potentially hazardous wiring problems in your wall circuit. Two 1.5A USB charging ports keep mobile devices charged even when your wall outlets are occupied. The BE850G2 features a hot-swappable, user-replaceable battery, so you can restore full backup performance without shutting down connected equipment or replacing the entire unit. The compatible genuine APC replacement battery is RBC17 (sold separately), a fully assembled 12V 6.5Ah sealed lead-acid battery cartridge designed for easy replacement. Backed by APC's trusted Back-UPS series, a 3-year warranty, and a $75,000 lifetime equipment protection policy, the BE850G2 is a compact, floor- or wall-mountable battery backup built for a home office, computer workstation, or home network — delivering dependable power protection for the equipment that keeps you productive and connected.
