APC 1500VA/900W Back-UPS Pro UPS Battery Backup (BR1500G) Review (2026)

Who this UPS fits

This UPS is built for a home office or workstation that cannot afford to lose power mid-task, covering a desktop tower, one or more monitors and networking equipment like a router or modem from a single battery bank. Its 10 outlets split between battery-backed and surge-only protection give room to plug in a full setup rather than choosing which device gets backup power. APC has built UPS hardware for decades, and the Back-UPS Pro line adds features aimed at demanding home offices rather than simple surge protection alone. Anyone who only needs to protect a single small device, or who lacks floor space under a desk for a unit this size, should look at a smaller capacity model instead.

Capacity and build explained

The manufacturer's official specification lists this unit at 1500VA and 865W, delivered through 10 NEMA 5-15R outlets, five of which provide battery backup and five of which offer surge protection only. It uses a user-replaceable lead-acid battery, so the unit does not need to be shipped back to APC when the battery eventually wears out, and a compatible external battery pack can be added later to extend runtime further. An LCD display on the front shows load and battery status as bar graphs, and APC includes PowerChute software for automatic, graceful shutdown of a connected PC during extended outages. The tower measures roughly 11.85 by 4.41 by 15.04 inches and weighs about 26.7 pounds, sizable enough to need dedicated floor or shelf space under a desk.

Living with it day to day

Day to day, the unit sits quietly until a power event triggers the battery, at which point the LCD and audible alerts communicate status so you know how much runtime remains. Automatic voltage regulation corrects brownouts and small surges without switching to battery power, which extends battery life by handling minor fluctuations differently from a full outage. Three soft-touch buttons on the front handle basic configuration without needing a computer connection. APC backs the UPS itself with a 3 year warranty and the battery with a 1 year warranty, giving a documented service window that smaller, unbranded UPS units in this space often do not offer at all.

Trade-offs and how it compares with other UPS units in this guide

Against its close sibling, the APC BX1500M, which matches this unit on VA rating and outlet count in a similarly sized tower, the two are close enough in role that the choice often comes down to which specific model is in stock or priced better at the time of purchase. The CyberPower CP1500AVRLCD, ranked just below both APC units, offers 12 outlets against this unit's 10, giving CyberPower a slight edge in raw outlet count for buyers who want to plug in more devices individually. Anyone who does not need this much capacity should look at the APC BX1000M in this guide, which trades runtime for a smaller, lighter and less expensive package better suited to a single monitor and a small desktop.

Verdict and who should pick something else

This UPS earns the top score in this guide, our score of 9.2 out of 10, for its high capacity, user-replaceable battery, informative LCD display and a documented 3 year warranty from an established brand. It is the right pick for anyone protecting a full desktop workstation with multiple monitors and networking gear who wants real runtime during an outage rather than just a few minutes of grace period. Buyers with lighter power needs, tighter floor space, or a smaller budget should look at the APC BX1000M or BE850G2 further down this guide, since this unit's size and price are only justified by genuinely needing its full 1500VA capacity.
