About this UPS
The APC Back-UPS Pro BR1500MS is a high-performance UPS designed to protect your home office, desktop computers, gaming PCs, networking equipment, and smart home devices from power interruptions, surges, and voltage fluctuations. Compact and easy to set up, it provides peace of mind for both work and entertainment environments where reliable power is essential.
With a capacity of 1500VA / 900W, this UPS delivers enough backup power to keep your systems running during outages. The built-in Automatic Voltage Regulation (AVR) stabilizes voltage without draining the battery, while the LCD display keeps you informed of load levels, runtime, and system status at a glance. Backup runtime is approximately 14.5 minutes at half load (450W) and 4.1 minutes at full load (900W), giving you the time you need to safely continue working or shut down equipment.
This refurbished unit is supplied with brand-new batteries, fully tested to ensure dependable performance, and covered by a 1-year full replacement warranty. Units may show minor cosmetic imperfections, such as scratches or scuffs, but these do not affect functionality.
A cost-effective and dependable solution, the BR1500MS is ideal for maintaining uptime, protecting sensitive electronics, and ensuring smooth operation in both home and business environments.

What 'refurbished' means here
Refurbished. This unit has been load-tested with new batteries and is covered by our 1-year UPSPLUSBATTERY warranty (replaces the original manufacturer warranty). Cosmetic wear is normal for refurbished hardware; functional condition is verified before shipping. New units carry the full manufacturer warranty registered to the buyer.

Before you order
How do I know this UPS will run my equipment?
Add up the wattage draw of every device you'll plug in (servers, switches, monitors). The UPS's wattage rating — not VA — is the number that matters. Aim for the UPS to run at 60–70% of capacity at full load: this gives headroom for inrush current and a meaningful runtime margin. Email us your equipment list and we'll size the right UPS within one business hour.
What's covered by the warranty, and how long does it last?
New units carry the full manufacturer warranty registered to you on receipt. The manufacturer handles claims directly via their North American support channel. Refurbished units are covered by our own 1-year UPSPLUSBATTERY warranty handled in-house in Canada.
Can I extend runtime beyond what's shown above?
Many Smart-UPS-class models accept an external battery pack (XBP) connected to the rear battery port. If this UPS shows "Extended Runtime Capable: Yes" in the spec grid above, an XBP is supported. Compatible XBPs and the runtime gain they deliver vary by model — contact us if you don't see the right XBP in our catalogue.
