Ranked #3 in Best UPS Battery Backups

APC BR1500G

4.0

2 sourcesall derived$353.09as of Jul 1

The APC Back-UPS Pro 1500G is a line-interactive UPS for power users and small businesses, rated 1500VA/865W with 10 outlets, 5 of them battery-backed. Reviewers liked the solid build quality and the bundled PowerChute Personal Edition software for monitoring, but several found 5 battery-backed outlets too restrictive. Output is stepped sine wave, and the battery is replaceable under a 3-year warranty. Reviewers rated its performance well; the sticking point is EU pricing, which looks poor next to US availability.

Strengths

— 1500VA/865W capacity suitable for mid-range desktop setups
— Line-interactive topology with voltage regulation capabilities
— Includes PowerChute Personal Edition software for monitoring and diagnostics

Watch-outs

— Only 5 of the 10 outlets are battery-backed, and retailer listings disagree on the exact count
— Higher price point in EU market compared to US
— Internal fan causes somewhat high noise levels during operation

Higher ratedRanked #1 in Best UPS Battery Backups

Eaton 5P 1550

4.5

2 sources1 derived$760as of Jul 31

The Eaton 5P1550GR is a rackmount UPS for data center environments, rated 1550 VA / 1100 W with true sine wave output. Reviewers noted the compact 1U form factor and the 6 C13 outlets, which can be grouped programmatically so critical and non-critical equipment are handled separately. ABM battery management extends battery life and warns you ahead of a replacement. Performance is solid for the class, though swapping the battery is on the user and the included power cord runs only 6 feet. It fits anyone who needs dependable rackmount power protection.

Strengths

— 1U rackmount form factor with compact footprint suitable for data center environments
— True sine wave output waveform for reliable power delivery to sensitive equipment
— 6 C13 outlets with programmable groups for critical and non-critical device management

Watch-outs

— Battery replacement requires user intervention and is not plug-and-play
— Limited runtime options without extended battery capability
— Power cord is only 6-foot length which may require additional cable management
